Java script code:
<script type="text/javascript">
$(document).ready(function () {
$("#visualization").css('display', 'none');
});
</script>
<script type="text/javascript">
$('#info a').click(function drawVisualization() {
$("#visualization").css('display', 'block');
});
</script>
On load i am hidden the div and i want show the div by clicking the button
asp.net code:
<asp:Button ID="Button1" runat="server" Text="Button"
onclick='blue' />
c# CODE:
protected void blue(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(), "TestInitPageScript",
string.Format("<script type=\"text/javascript\">drawVisualization();</script>"));
}
i am fairly new to the coding;can anyone help me to solve this issue. After invisibling i am not able to show the visualization(div)
There's a much easier way to do this, which doesn't involve an entirely unnecessary post-back to the server. Something like this:
$('#<%= Button1.ClientID %>').click(function () {
$("#visualization").show();
});
This would assign a JavaScript click handler to the client-side rendered output of Button1. Of course, Button1 still causes a post-back, but since it doesn't need to do anything server-side it doesn't even need to be a server-side control. Make it something like this:
<input type="button" id="button1" value="Button" />
Then adjust the jQuery selector to use the client-side id:
$('#button1').click(function () {
$("#visualization").show();
});
If all you're doing is showing/hiding page elements, and you're already using JavaScript to do it, server-side code is entirely unnecessary.
you can use it like
Page.ClientScript.RegisterStartupScript(this.GetType(),"CallMyFunction","$('#visualization').css('display', 'block');",true);
<asp:Button ID="Button1" runat="server" Text="Button"
onclick='display()' />
<script>
function display()
{
$("#visualization").show();
}
</script>
$(document).ready(function () {
$("#visualization").css('display', 'none');
$('#Button1').click(function(){
$("#visualization").css('display', 'block');
});
});
I would just do it all on the client. Something like this would work.
$("#Button1").on("click", function(e){
$("#visualization").show();
});
If there's no reason to do a postback, you can do e.preventDefault(); after the call to .show();
Instead of Creating a Button OnClick event you can write a simple jquery or javascript to get the desired output
There are various ways to solve the above problem.
1)You can write OnClientClick attribute of Button control in asp.net and pass the value as
the javascript function name that you have created in the above code as drawVisualization()
and another important thing is that you will have to remove the runat="server" attribute because it causes the postback(means your page again reloads which will cause the div to hide)
2)You can create a jquery button click event
for eg:
First of all just create a simple function
function drawVisualization() {
$("#visualization").css('display', 'block');
});
and then the button click event
$('#button1').on( "click", function() {
drawVisualization(); //call the function that you have created to show the desired output
});

I have jquery code on cc.js that I need to execute when an asp.net button is clicked.
The code on cc.js has a variable called settings and then submits these settings to an API (POST action) with the following code:
'Transaction Submit'
$.ajax(settings).done(function (response) {
console.log(response);
});
Basically I need this button <asp:Button ID="BtnSubmit" runat="server" Text="Submit" /> to execute that jquery code. How can I do so?
You are looking for the OnClientClick property
<asp:Button ID="BtnSubmit" runat="server" OnClientClick="JSFunctionName(); return false;" Text="Submit" />
You will need to add the additional return false statement to prevent a post back from occurring if you button element is located inside a form.
This is assuming you want to decouple your front end html from your js code by using an inline call. If that is not the case then you mod your cc.js to autobind on the element as others have mentioned. One thing they left out is that in that process is that IF you button is inside a form then you need to prevent the auto-post back like so:
$(document).ready(function() {
$("#BtnSubmit").click(function(){
JSFunctionName();
e.preventDefault();
});
});
If the ID of the button is BtnSubmit, then you should be able to add a event handler like this.
$(document).ready(function() {
$("#BtnSubmit").click(function(){
alert("button clicked - do stuff here.");
});
});
change the alert("button clicked - do stuff here."); to your ajax request code.
You can write the following code to create an event on Button click to call the jquery method..
Basically, you take the ID by $("#btnSubmit") and on its click event write your Ajax function.
$("#BtnSubmit).on('click',function() {
// your ajax code here
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<asp:Button ID="BtnSubmit" runat="server" Text="Submit" />
Hope this helps.
Just Add a click event with your button id using jquery..
$("#BtnSubmit").on('click',function(){
console.log('success...');
//ajax call here...
});
You can use Ajax within JS functions. I'm not sure what version of .NET you're using, but I'll answer with what I know for MVC 5.
Here's how I would do it:
HTML
<button id="SubmitBtn">Submit</button>
JS(JQuery)
$('#SubmitBtn').on('click', function () {
//Transaction Submit
$.ajax({
type: "POST",
url: '/ProjectName/Controller/Method',
data: { methodParameter1: data1, methodParameter2: data2 },
success: function (data) {
//do whatever
}
error: function (response) {
//do whatever
}
});
});
I want to know all possible ways to trigger a button in jQuery, I tried this but it's not working,
$("#<%=btA.ClientID%>").trigger('click');
Note: its a ASP.Net button and what I want is to trigger button click so that it will trigger a code-behind click method of buttonA.
Try this
$("#<%=btA.ClientID%>").click();
if it doesn't work try to alert this and check if it is getting accessed by JQ
alert($("#<%=btA.ClientID%>").length);
Have you registered the event with jquery in following manner
$(function(){
$("#<%=btA.ClientID%>").click(function(){
// your logic here
});
});
One more thing to confirm, are you loading this button directly on page load or you are having some page update panel which load it afterwords?
If yes then you should bind the event to button in following manner
$(document).on('click',"#<%=btA.ClientID%>", function() {...});
$("#<%=btA.ClientID%>").click();
Or
$("input[id$='yourbuttonId'").click();
Reason that trigger not working is Jquery only allow you to trigger a click that Jquery has created. Use the trigger route after you have written a click listener.
Its beats me since it should be a very straightforward thing. I actually just tried it out and it worked without a hitch. Here is my markup:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#<%=btA.ClientID%>").trigger('click');
});
</script>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lbA" runat="server"></asp:Label>
<asp:Button ID="btA" runat="server" OnClick="btA_Click" Text="Click Me!" />
</div>
</form>
</body>
</html>
... and I have this method in my code behind:
protected void btA_Click(object sender, EventArgs e)
{
lbA.Text = "Hello World!";
}
When the application runs, it triggers the click event of the btA button fires immediately and the Hello World! text is rendered on the label. Check if you could be missing something.
$("#<%=btA.ClientID%>").click();
I believe this is the only other way.
May be you are trying to wire the event,when the control itself is not loaded on to the page.
Try this instead.It buys a little bit of time and then wires up the event.
setTimeout(function () {
$("#<%=btA.ClientID%>").trigger('click');
}, 10);
I always make ClientIdMode="static" so that you can easily call the element with the same id you configured in the page..
So you dont hvae to use ClientID.. More over you cant use asp.net code in a separate js file.
$("#<%=btA.ClientID%>").trigger('click');
to
$("#btA").click();
Asp button is not working in a jquery dialog box:
<script type="txt/js">$(function () {$('#<%= ButtonEmail.UniqueID %>').button();});</script>
<div id="dialog-modal" title="Cadastro">
<p>Digite seu email para que eviemos o link do cadastro para ele:</p>
<p><asp:TextBox ID="TextBoxEmail" CssClass="ui-corner-all" runat="server"></asp:TextBox>
<asp:Button ID="ButtonEmail" runat="server" Text="Enviar Link" onclick="ButtonEmail_Click" /></p>
<div><asp:Label ID="LabelEmail" runat="server" Text="teste"></asp:Label></div>
</div>
c# code:
protected void ButtonEmail_Click(object sender, EventArgs e)
{
...
}
even when a delete this: $(function () {$('#<%= ButtonEmail.UniqueID %>').button();}); dont work, the button stays with the original design, but dont work
Use this
<script type="text/javascript">
$(function () {
$('#<%= ButtonEmail.ClientID %>').button();
});
</script>
Please note the ClientID which replaced UniqueId. Also ensure that the dependent scripts are loaded (There should be no javascript errors).
After reading some of the comments on the other answer, I'm starting to wonder if possibly it's your server side click event which is not working? In that case you're probably going to have to provide more information and code.
To make an asp.net server side click work in a dialog, ensure that the dialog is part of the form (after its been made into a dialog by jquery. Details are here. jQuery UI Dialog with ASP.NET button postback
may be something like this
var buttonId = <%= ButtonEmail.UniqueID %>;
$(function () {$('#' + buttonId).button();});
Im well aware of the fact that the problem im having has been asked and discussed on SO before, but i've read them all countless times and none of them actually helped me solve my problem.
I am working with Visual studio, ASP.NET and C#.
Here's what i want to do exactly:
I have a JQuery dialog with a Label inside of it. I also have a button.
When that button is pressed,i want to jump inside the button's click event and set a text for the label inside the JQuery Dialog. Then i want the dialog to open, displaying the label with the text that has just been set in my button's click handler.
Here's the content that should be in my JQuery dialog (note that i've simplified my code for this question):
<div id="dialog" title="Basic dialog">
<asp:Label ID="Label1" runat="server" ></asp:Label>
</div>
On my page i I have an ASP.NET button, with an onClick event. In the code behind, inside the click event for my button i set the text for Label1.
This is my button:
<asp:LinkButton ID="testButton" runat="server" onClick="button_Click" text="click me"/>
and here's the code behind click handler:
protected void button_Click(object sender, EventArgs e)
{
Label1.Text = "Hello";
}
This actually works, but not as i want it to.
My problem:
For some reason the label's text only gets set the SECOND time i press the button. So that means, the first time i click the button, the dialog opens, displays nothing, then the dialog dissapears and the page posts back. The second time i press the button, i see that the text has been set for the label, but then again the dialog instantly dissapears and the page posts back.
i've tried adding the following to my button: OnClientClick="return false;"
When i do this the postback issue is gone, but now my button's click event doesn't fire.
I've also tried to add the following to my script: event.preventDefault(); This causes the same problem as with the return false;, the page doesn't postback but simply does not jump into the button's click event.
here's my dialog script:
<script>
$(function () {
$('#dialog').parent().appendTo($("form:first"))
$("#dialog").dialog(
{
autoOpen: false,
buttons: {
"Ok": function () {
$(this).dialog("close");
}
}
}
);
$("#testButton")
.button()
.click(function openConfirmDialog() {
$("#dialog").dialog("open")
});
});
</script>
Basically all i want to do is click a button to set a label's text, open a dialog, and keep that dialog open until a user closes it.
I might be missing something, but it amazes me to see how hard it is to do something as simple as i want to do.
kind regards,
Jane
When page is posted back by clicking on button control, dialog is refreshed and closed. You need to implement a way to show dialog box when page is posted back with data within in.
i: In first step create a variable at code behind. e.g
protected string PostBackOption ="";
ii: Add check to set dialog option text when page is post back in page load or page pre render event. e.g
if (Page.IsPostBack)
{
PostBackOption = "$(\"#dialog\").dialog(\"open\");";
}
iii: Now call this variable within javascript as shown below.
<script>
$(function () {
$('#dialog').parent().appendTo($("form:first"))
$("#dialog").dialog(
{
autoOpen: false,
buttons: {
"Ok": function () {
$(this).dialog("close");
}
}
}
);
$("#<%= testButton.ClientID %>")
.button()
.click(function openConfirmDialog() {
$("#dialog").dialog("open")
});
<%=PostBackOption %>
});
Now when you click on click me button, page will postback, after post back dialog will not dis appear and label will be populated with text "hello" properly.
I created a simple example decides whether or not to autoOpen based on your Label containing a value. The dialog goes away due to the page refreshing. You could use UpdatePanels if you wanted to eliminate the whole page posting back, or you could do something like this:
HTML and jQuery:
<!DOCTYPE html>

<head runat="server">
<meta charset="utf-8" />
<title>jQuery Dialog Demo</title>
<link rel="stylesheet" type="text/css" href="//ajax.aspnetcdn.com/ajax/jquery.ui/1.8.16/themes/cupertino/jquery-ui.css" />
</head>
<body>
<form runat="server">
<div id="dialog" title="Basic dialog" style="display: none;">
<asp:Label ID="Label1" runat="server"></asp:Label>
</div>
<asp:LinkButton ID="testButton" runat="server" onClick="button_Click" text="click me"/>
</form>
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.ui/1.8.16/jquery-ui.min.js"></script>
<script type="text/javascript">
var $labelText = $("#Label1").html().trim(),
$dialog = $("#dialog").dialog({
autoOpen: $labelText.length,
buttons: { "Ok": function () { $(this).dialog("close"); } }
});
$("#testButton").button().click(function() {
if ($labelText.length) $dialog.dialog("open");
});
</script>
</body>
</html>
C# CodeBehind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class test6 : System.Web.UI.Page
{
protected void button_Click(object sender, EventArgs e)
{
Label1.Text = "Current time in ticks: " + DateTime.Now.Ticks.ToString();
}
}
Output:
Your label is already added to the form, no need for adding the dialog to the form. ASP.Net only accepts controls that are put into the <form runat="server"> tag.
i'm facing a problem tryin to execute a simples jquery inside my userControl. This jquery doesn't has anything with the pages that is goin to load my UC.
the code looks like it:
<script type="text/javascript">
function pageLoad(s, e) {
$(document).ready(function() {
tooltip();
});
}
</script>
i tryied to debug using firebug but not even the breakpoint is reach.. by some reason i think that the browser is just ignoring my script.
it's my first ask here.. sry anything.
you need to write just below lines because ready function get fire automatically when page get loaded with all controls
<script type="text/javascript">
$(document).ready(function() {
tooltip();
});
</script>
how about:
<script type="text/javascript">
$(document).ready(function() {
tooltip();
});
</script>
