Please advice
<script type="text/javascript">
function getWindow(FromUserID, UserID, PerID, UserName) {
$.ajax({
type: "POST",
url: "TestMessageService.asmx/OpenWindow",
data: "{'FromUserID': '" + FromUserID + "', 'ClickedUserID': '" + UserID + "', 'ClickedPerID': '" + PerID + "', 'ClickedUserName': '" + UserName + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var msgs = response.d;
$('#div_Panel').append(msgs).fadeIn("slow");
var elements = $('.panelContent');
for (var i = 0; i < elements.length; i++) {
elements[i].scrollTop = elements[i].scrollHeight;
}
},
failure: function (msg) {
$('#div_Panel').text(msg);
}
});
}
</script>
[WebMethod]
[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
public string OpenWindow(string FromUserID, string ClickedUserID, string ClickedPerID, string ClickedUserName)
{
string checkNewMsg = "<script type=\"text/javascript\">window.setInterval(fc_" + ClickedUserName.Replace(" ", "") + ", 10000); function fc_" + ClickedUserName.Replace(" ", "") + "() { alert('" + ClickedUserName + "'); }</script>";
StringBuilder sb = new StringBuilder();
sb.Append(checkNewMsg + "<div class=\"ch_Box\">");
sb.Append("<div class=\"ch_Header\">");
sb.Append("<div style=\"float:left;margin-top: 9px;margin-left: 8px;\"><img src=\"Images/Status.png\"></div>");
sb.Append("<div id=\"roomUsers\" class=\"ch_HeaderItem\">" + ClickedUserName + "</div>");
sb.Append("<div onclick=\"closePanel(this)\" style=\"width: 23px; height: 27px; cursor: pointer; position: absolute; margin-left: 232px;\"><img style=\"height: 20px; margin-top: 4px;\" src=\"Images/close.png\"></div>");
sb.Append("<div id=\"cont_" + ClickedUserID + "\" class=\"panelContent\">" + FillMessages(roomID, FromUserID.ToInt()) + "</div>");
sb.Append("<div class=\"ch_Text\">");
sb.Append("<input id=\"msg_" + FromUserID + "_" + ClickedUserID + "_" + ClickedPerID + "_" + roomID + "\" type=\"text\" class=\"inp\" onkeypress=\"PushText(this)\" autocomplete=\"off\" /></div>");
sb.Append("</div></div>");
return sb.ToString();
}
I don't know why doesn't return script tag an asmx but when i remove the tag and then in the js side while i add script' tag before return value the problem is solved.
Just like this;
In asmx side;
string checkNewMsg = "window.setInterval(fc_" + ClickedUserName.Replace(" ", "") + ", 10000); function fc_" + ClickedUserName.Replace(" ", "") + "() { alert('" + ClickedUserName + "'); }#func#";
In Js Side;
success: function (response) {
var msgs = response.d;
var arrCont = msgs.split('#func#');
var MsgCont = "<script type=\"text/javascript\">" + arrCont[0] + "<\/script>";

I'm generating a table usinf jQuery. in each row I have an input field, that should search some values from DB usibg autocomplete. first row works perfectley but with the second I have problems, it returns in autocomplete only a value from the field above, I have no idea how can i fix it... can somebody help?
here is my code:
$.ajax({
type: "GET",
url: "/Home/JsonWeekEvents",
dataType: "JSON",
success: function (result) {
$.each(result, function (i, val) {
var trow = $('<tr/>').data("id", val.Id);
//trow.append('<td>' + val.Id + " " + '</td>');
trow.append('<td style="padding:5px; width:100px; height:70px"></td>');
trow.append('<td valign="top" style="padding:2px; width:150px; height:100px">' +
'<div class="ui-widget">' +
'<input size="10" maxlength="10" id="tagsM" class="tags" />' +
'<input type="button" id="addBtn" onclick="addEvent();" size="5" value="+" /><br/>' +
'<div style="text-align:center" id="desc_Num">' + val.Monday + '</div >' +
'</div >' +
'</td>');
tab.append(trow);
});
$("tr:odd", tab).css('background-color', '#C4C4C4');
$("#weekEvents").html(tab);
},
error: function () {
alert("Failed! Please try again.");
}
});
var tab = $('<table class=MyTable border=1 ></table>');
var thead = $('<thead></thead>');
thead.append('<th style="padding:5px">FSE' + " " + '</th>');
thead.append('<th style="padding:5px">Monday' + " " + '</th>');
thead.append('<th style="padding:5px">Tuesday' + " " + '</th>');
thead.append('<th style="padding:5px">Wednesday' + " " + '</th>');
thead.append('<th style="padding:5px">Thursday' + " " + '</th>');
thead.append('<th style="padding:5px">Friday' + " " + '</th>');
thead.append('<th style="padding:5px">Saturday' + " " + '</th>');
thead.append('<th style="padding:5px">Sunday' + " " + '</th>');
tab.append(thead);
tab.on("focus", "input[class='tags']", function (e) {
//var prefix = $('.tags').val();
$('.tags').autocomplete({
source: function (request, response) {
$.ajax({
url: "/Home/GetSearchValue",
dataType: "json",
data: { search: $('.tags').val() },
success: function (data) {
response($.map(data, function (item) {
return {
label: item.Title + ', ' + item.Description, value: item.Title,
Id: item.Id,
Title: item.Title,
Description: item.Description,
Location: item.Location
}
}));
},
error: function (xhr, status, error) {
alert("Error!" + xhr);
},
});
}
});
Would advise something like the following:
tab.on("focus", "input[class='tags']", function(e) {
if (!$(this).hasClass("ui-autocomplete")) {
$(this).autocomplete({
source: function(request, response) {
$.getJSON("/Home/GetSearchValue", {
search: request.term
},
function(data) {
response($.map(data, function(item) {
return {
label: item.Title + ', ' + item.Description,
value: item.Title,
Id: item.Id,
Title: item.Title,
Description: item.Description,
Location: item.Location
}
}));
});
}
});
}
});
This will initialize autocomplete on focus event. If it's already initialized, that will not be repeated. The source will perform a GET request and search for the request.term from the User's input on that specific field.
I am adding some html/css in div.InnerHtml by applying foreach loop reading each directory contents to post images, and i want to call function showfile(dynamic parameter) into it.
how should i do this?
the showfiles(dynamic parameter) function is working fine, but i want to make it work after user clicks the controls generated in div, which is not working, please have a look on my code and give me suggestion.
public void Showimages( string fname)
{
string name = Path.GetFileName(fname); //select only name.ext
str2 = "<div style='max-width:250px; max-height:170px;'>"
+ "<a href ='" + filepath2 + "/" + name + "' >"
+ "<img class='img-responsive' src='" + filepath2 + "/" + name + "'>"+name+"</a></div>"; //post image + name in loop
imgcontainer.InnerHtml += str2;
}
public void Generatecontrol(string dp)
{
//linkdiv.InnerHtml += "<asp:LinkButton runat='server' class='linkb' OnClick='Showfiles(" + dp.ToString()+ ")' >" + dp.ToString() + "</asp:LinkButton><br />";
linkdiv.InnerHtml += "<span class='col-lg-4'><asp:LinkButton runat='server' class='col-lg-4 linkb' OnClick='Showfiles' CommandArgument=" + dp.ToString()+ " ><img src='/pimages/folder.jpg' height='75' width='75' border='0'/><br />" + dp.ToString() + "<br /></asp:LinkButton></span>";
}
See you are passing the value as CommandArgument, so you have to take the same from CommandArgument. Change the signature of Showimages like the following:
public void Showimages(object sender, CommandEventArgs e)
{
string name = Path.GetFileName(e.CommandArgument.ToString());
// your code here
}
Pritesh,
If your main concern is only displaying images dynamically, then you can use jquery, here below I prepared a small snippet, please look at once,
Backend code:
public List<string> GetImages()
{
string fileName = "";
string[] files = System.IO.Directory.GetFiles("");
List<string> listImages = new List<string>();
foreach (string file in files)
{
fileName = System.IO.Path.GetFileName(file);
listImages.Add(fileName);
}
return listImages;
}
HTML:
<div class="row" style="margin-top:20px;">
<div id="imgPreview"></div>
</div>
<button id="btnShowImage" onclick="ShowImages()">Show Image</button>
Jquery
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
function ShowImages() {
$("#imgPreview").html("");
$.ajax({
type: 'post',
url: '/xyz/GetImages',
data: formData,
success: function (response) {
if (response != null) {
var imageList =DisplayImages(response);
$("#imgPreview").append(imageList);
}
},
processData: false,
contentType: false,
error: function () {
alert("Whoops something went wrong!");
}
});
}
)};
function DisplayImages(data) {
var imageDiv ="";
if (data != null) {
$.each(data, function (index, value) {
//This is for dynamically generating image div. You can manipulate this section as per you need.
imageDiv = "<div style='max-width:250px; max-height:170px;'>";
imageDiv += "<a href ='~/your static path/" + value + "' >";
imageDiv += "<img class='img-responsive' src='='~/your static path/" + value + "'>" + value + "</a></div>";
});
}
return imageDiv;
}
</script>
Let me know if it helped.
I want to pass value through jQuery Json.The problem is that while passing the value then,it have some problem,thats why it is not calling c# code.
This is the html table:
$(function ()
{
debugger
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebForm7.aspx/BindCategoryDatatable",
data: "{}",
dataType: "json",
success: function (dt) {
debugger;
for (var i = 0; i < dt.d.length; i++) {
$("#tblid > tbody").append("<tr><td> <input type='checkbox' class='chk' id=" + dt.d[i].projectid + " /></td><td>" + dt.d[i].projectname + "</td><td>" + dt.d[i].Name + "</td><td>" + dt.d[i].technology + "</td><td>" + dt.d[i].projectliveurl + "</td><td><input type='image' src=" + dt.d[i].StatusImage + " onclick='actvstatus(" + dt.d[i].projectid + ", " + dt.d[i].status + ")' alt='Submit' width='18' height='18'> </td><td>" + dt.d[i].DisplayOrder + "</td><td> <i class='ui-tooltip fa fa-pencil' onclick='btnQueryString_Click(" + dt.d[i].projectid + ")' style='font-size:22px;margin-left: 32px;'></i><i class='ui-tooltip fa fa-trash-o' onclick='deleteRecord(" + dt.d[i].projectid + ")' style='font-size: 22px;margin-left: 32px;color:red'></i> </tr>");
}
$("#tblid").DataTable();
},
error: function (result) {
alert("Error");
}
});
});
This is my c# Code:
[WebMethod]
public static List<mProjects> BindCategoryDatatable(int catid)
{
clsProjectBL objcategory = new clsProjectBL();
List<mProjects> modelCategory = new List<mProjects>();
DataTable dtCategory = new DataTable();
//dtCategory = objcategory.GetAllCategoryDetails("admin");
dtCategory = objcategory.GetAllProjectDetails("admin", catid);
if (dtCategory.Rows.Count > 0)
{
modelCategory = (from DataRow dr in dtCategory.Rows
select new mProjects()
{
projectid = Convert.ToInt32(dr["projectid"]),
CategoryID = Convert.ToInt32(dr["CategoryID"]),
projectname = dr["projectname"].ToString(),
Name = dr["Name"].ToString(),
technology = dr["technology"].ToString(),
projectliveurl = dr["projectliveurl"].ToString(),
DisplayOrder = Convert.ToInt32(dr["DisplayOrder"]),
status = Convert.ToBoolean(dr["status"]),
StatusImage = dr["StatusImage"].ToString(),
//Deleted = Convert.ToBoolean(dr["Deleted"])
}).ToList();
}
return modelCategory;
}
The value is not pass through webmethod...
Your back-end required a parameter catid so you have to pass catid to AJAX call as #BenG and #palash answer with data attribute.
data: { catid: 1 }
Or you pass it to the url with format
url: "WebForm7.aspx/BindCategoryDatatable?catid=" + YOUR_ID.
Otherwise, it will not be worked because BindCategoryDatatable return an empty list.
I am creating a webpage in which I fetch top 8 rows from database on page load. I put load more button on my bottom of my web page. What I want is when I click on load more button it shows me next new 8 rows and skip previous records and if there is no new record found then show me nothing.
Below is my code which I was trying but it was repeating same duplicate records.
//Below event is fetching top 8 rows on page load
function viewAllEvents() {
$.ajax({
url: "Event.aspx/viewEvents",
data: null,
contentType: "Application/json; charset=utf-8",
responseType: "json",
method: "POST",
success: function (response) {
var x = response.d;
for (var i = 0; i < x.length; i++) {
$("#tabss > .event-container > .row").append(
"<div class='col-md-3'><div class='event'><div class='eventsimg'><img src= " + '../MediaUploader/' + x[i].EVE_IMG_URL + " alt=''></div><div class='event-content'><h3 class='title'>" + x[i].EVE_NAME + "</h3><p>" + x[i].EVE_DESCRIPTION + "</p><input type='button' id=" + i + " class='btn btn-pri' style='padding: 9px 9px;font-size: 12px;' onClick='eveReq(" + i + ", " + x[i].ID + ", " + x[i].EVE_CAT_ID + ");' value='Send Request' /><input type='button' class='btn btn-pri' style='padding: 9px 9px;font-size: 12px;margin-left: 2px;' value='Read More' /></div><div class='links clearfix'></div></div></div>"
);
}
},
error: function (xhr) {
alert(xhr.status);
},
Failure: function (response) {
alert(response);
}
});
}
//Below event is for when load more button is clicked
function addTabs() {
$.ajax({
url: "Event.aspx/addTab",
data: null,
contentType: "Application/json; charset=utf-8",
responseType: "json",
method: "POST",
success: function (response) {
var x = response.d;
for (var i = 0; i < x.length; i++) {
$("#tabss > .event-container > .row").append(
"<div class='col-md-3'><div class='event'><div class='eventsimg'><img src= " + '../MediaUploader/' + x[i].EVE_IMG_URL + " alt=''></div><div class='event-content'><h3 class='title'>" + x[i].EVE_NAME + "</h3><p>" + x[i].EVE_DESCRIPTION + "</p><input type='button' id=" + i + " class='btn btn-pri' style='padding: 9px 9px;font-size: 12px;' onClick='eveReq(" + i + ", " + x[i].ID + ", " + x[i].EVE_CAT_ID + ");' value='Send Request' /><input type='button' class='btn btn-pri' style='padding: 9px 9px;font-size: 12px;margin-left: 2px;' value='Read More' /></div><div class='links clearfix'></div></div></div>"
);
}
},
error: function (xhr) {
alert(xhr.status);
},
Failure: function (response) {
alert(response);
}
});
}
Below is my web methods:
[WebMethod]
public static List<EVENT> viewEvents()
{
var slist = new List<EVENT>();
var db = new BLUEPUMPKINEntities();
db.Configuration.LazyLoadingEnabled = false;
slist = db.EVENTS.OrderByDescending(eve => eve.ID).Take(8).ToList();
return slist;
}
[WebMethod]
public static List<EVENT> addTab()
{
var slist = new List<EVENT>();
var db = new BLUEPUMPKINEntities();
db.Configuration.LazyLoadingEnabled = false;
slist = db.EVENTS.OrderByDescending(eve => eve.ID).Skip(8).Distinct().ToList();
return slist;
}
Though I didn't use your code but I believe if you can go through this example below then you'll know what to do:
First declare a global variable which will count the record returned so far:
private int recordCount = 0;
Then in the click event do the following:
//My sample data
int[] data = { 1, 2, 3, 4, 5, 6, 7, 8 };
var results = data.Skip(recordCount).Take(2);
//Increment recordCount by the count of the results return above
recordCount+= results.Count();
if (results.Count() > 0)
{
//return results
}
