I have a javascript file that Select a button using jQuery and check it for validation.the code is:
$(document).ready(function () {
$('#<%= btn_Insert.ClientID %>').on("click", function (event) {
if (Validate() != true) {
event.preventDefault();
}
});
function Validate() {
return (1 == 1);
});
but I can' get ClientID for button and I get this Error:
Object doesn't support this property or method
where is my mistake?How I can get Client ID for a server side Button?
thanks
EDIT 1)
When I add script in head part of page it works but when I write it to a JS file and add reference to it in head part it does not work
I suspect that the error comes from the fact that event has a special meaning in some browsers. Try renaming the variable:
function Validate() {
return (1 === 1);
}
$(function () {
$('#<%= btn_Insert.ClientID %>').on('click', function (evt) {
if (!Validate()) {
evt.preventDefault();
}
});
});
or even easier :
$('#<%= btn_Insert.ClientID %>').on('click', function() {
return Validate();
});
UPDATE:
Now that you have edited your question it is clear where the problem is. You are trying to use server side tags (<%= %>) in a separate javascript file. That's impossible. They will render literally and will not be processed by ASP.NET.
In order to solve your issue you could apply a CSS class to the button and then use a class selector:
$('.someClass').on('click', function() {
...
});
Another possibility is to use the ends with selector:
$('[id$="btn_Insert"]').on('click', function() {
...
});

Just add ClientIDMode="Static" to your server button control and use its ID in js w/o problems:
$('btn_Insert').on('click', function() {
return Validate();
});

I'm trying to integrate Page Builder by SiteOrigin into my plugin. I've added some custom fields under the row styles via the siteorigin_panels_row_style_fieldsfilter found here. One of the custom fields is a select. I would like fields to either be hidden or displayed when the select is at a certain value. I've enqueued the Javascript to Page Builder using the siteorigin_panel_enqueue_admin_scriptsaction as per the documentation, and have even added the panelsopen event with some test code:
jQuery( document ).ready(function($) {
$(document).on('panelsopen', function(e) {
$('select[name="style[test_field]"]').bind('change', function (e) {
if( $(this).val() == 'option1' ) {
$('input[name="style[second_field]').hide(500);
$('input[name="style[third_field]').show(500);
} else {
$('input[name="style[second_field]').show(500);
$('input[name="style[third_field]').hide(500);
}
});
});
});
However, this does not seem to be working. Any help or ideas how I could solve this would be greatly appreciated!
After some research I figured this out by using the ajaxComplete() function in jQuery. This is how it works:
$(function() {
$(document).ajaxComplete(function() {
$('select[name="style[test_field]"]').bind('change', function (e) {
if( $(this).val() == 'option1' ) {
$('input[name="style[second_field]').hide(500);
$('input[name="style[third_field]').show(500);
} else {
$('input[name="style[second_field]').show(500);
$('input[name="style[third_field]').hide(500);
}
});
});
});
I hope this helps anyone trying to achieve something similar.
is it possible to create a twitter-button , while clicking a link? :
http://fiddle.jshell.net/gmq39/22/
I tried with:
$.getScript('http://platform.twitter.com/widgets.js');
The "button", which appear´s has no functionlaity and style´s
Anybody know´s a workaround or what do i need to inlcude? need your help.. greetings!!
Use twttr.widgets.load(); to bind the twitter functionality to a dynamically added button.
Also, to make sure you don't load the script over and over again, you could first check if the script is already loaded with something like this
function twitter() {
if ($(".twitter-follow-button").length > 0) {
if (typeof (twttr) != 'undefined') {
twttr.widgets.load();
} else {
$.getScript('http://platform.twitter.com/widgets.js');
}
}
}
$(function () {
$('body').html('Follow #MagnusEngdal')
twitter();
});

I have a small problem that should be very easy to overcome. For some reason I cant work this out. So the problem is I cannot get a button to link to some jquery. My set-up is as follows (showing the relevant code):
Default.aspx
jQuery:
function getContent() {
var data = {
numberID: 1
};
$.jsonAspNet("ContentService.asmx", "GetContent", data,
function (result) {
$('#content').html(result);
});
}
jQuery(document).ready(function () {
getContent();
});
HTML:
<div id="content"></div>
ContentService.vb
<WebMethod()> _
Public Function GetContent(number As Integer) As String
Dim sb = New StringBuilder
sb.AppendLine("<table>")
sb.AppendLine("<tr>")
sb.AppendLine("<td class='ui-widget-header ui-corner-all'>Number</td>")
sb.AppendLine("</tr>")
sb.AppendLine("<tr>")
sb.AppendLine("<td>" & number & "</td>")
sb.AppendLine("<td><a href='#' id='test' class='fg-button ui-state-default ui-corner-all'><img src='" & Context.Request.ApplicationPath & "/images/spacer.gif' class='ui-icon ui-icon-pencil' /></a></td>")
sb.AppendLine("</tr>")
sb.AppendLine("</table>")
Return sb.ToString
End Function
So that's the basics of what I have everything works but I'm not sure how to get the a button (id='test') to get linked to some jQuery. I want it to be pressed and bring up a popup.
I have tried to put the jQuery on default.aspx but this doesn't seem to work unless the button is place in the HTML on that page.
$('#test').unbind('click').click(function () {
alert('Working');
});
I'm sure this is easy to do, but I have been trying for a while and cannot seem to get it to work.
Is the problem that you're trying to bind to the element that ISN'T in existance yet?
are you calling the $('#test').unbind('click').click(function () {
alert('Working');
}); BEFORE the service has returned?
$('#test').on('click', function () {
alert('Working');
});
This will bind the event to the '#test' element once it has been inserted in to the DOM.
As you load the content via ajax, you have to bind to $('#content'). Like this:
$(function () {
$('#content').on('click', '#test', function () {
e.preventDefault(); // if a default action is not needed needed
alert('Working');
});
});
I guess this is about not preventing the default behaviour of the A href tag. Now it will probably link to '#' instead of firing the onclick event.
$('#test').on('click', function (e) {
alert('Working');
e.preventDefault();
});
You could try to wrap this in a document ready, or eventually use the .on binder from jQuery, since it's dynamic content.
Solved
It was a very small thing that caused this. The code to fix this problem is as follows:
$('#test').unbind('click').click(test);
This needed to go inside the function with the json so:
function getContent() {
var data = {
numberID: 1
};
$.jsonAspNet("ContentService.asmx", "GetContent", data,
function (result) {
$('#content').html(result);
$('#test').unbind('click').click(test);
});
}
Thank you to everyone that has tried to help me.
I have a javascript function that i have named refreshProjects(), what it does is filter a dropdownlist depending on what was selected in a previous dropdownlist. But i need to also filter my list direcktly after the page has finishd loading.
I have tried using the code window.onload = refreshProjects(id) with no sucsses, but onload workes when i use window.onload = alert('This page has finished loading!'), so i know that part off the script works. So how do i call a javascript function on load, i thought that it would be simple but evrything i tried have failed.
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
window.onload = refreshProjects(id); <-- Problem
$("#ddCustomers").change(function () {
refreshProjects($(this).val());
});
function refreshProjects(id) {
var projects = $("#ddProjects");
$.get('#Url.Action("FilterProjects","TimeEntry")', { customerId: id },
function (result) {
// clear the dropdown
projects.empty();
//Add a deafult "null" value
$("#ddProjects").get(0).options[0] = new Option("[ - No project - ]", "-1");
// rebuild the dropdown
$.each(result, function (i, e) {
projects.append($('<option/>').text(e.Text).val(e.Value));
});
});
}</script>
}
This is for MVC 4.5.
Try changing window.onload = refreshProjects(id); to:
window.onload = function() { refreshProjects($("#ddCustomers").val()); };
Onload expects a callback function. You were directly executing refreshProjects() and setting the return value as the onload.
But since you seem to be using jQUery, you could do the following:
$(function() {
refreshProjects($("#ddCustomers").val());
});
This will execute refreshProjects when the document is ready (which actually is before window load).
You can also try to use the following:
$(document).ready(function () {
refreshProjects(id);
});
This should work aswell if you are using jQuery.
After getting a new page with $.get none of the javascript will run on the new page.
Is there a way to make javascript use the new page too?
Many thanks
Dorjan
Edit: Example:
$(function() {
$('.viewPage').click(function() {
$('#mainarticle').fadeOut('slow')
$.get($(this).attr('href'), { js: "1" }, function(data) {
$('#mainarticle').html(data).fadeIn('slow');
});
return false;
});
});
Now this works fine however, the new page's anchor tags won't trigger (lets say it has a .viewPage).
I hope that clarify's the issue.
You need to bind events to your anchors using live:
$('a.something').live("click",function() {
alert('this will still work after a.something has been replaced via ajax');
});
Another way using $.get's callback:
$.get( "page.html", function(data) {
$('#someDiv').html(data);
$('a.something').click(function() {
alert('this will still work after a.something has been replaced via ajax');
});
});
Now that I've seen your code:
$(function() {
$('.viewPage').live("click",(function() {
$('#mainarticle').fadeOut('slow')
$.get($(this).attr('href'), { js: "1" }, function(data) {
$('#mainarticle').html(data).fadeIn('slow');
});
return false;
});
});
Yep; there is another jquery ajax method that will take the returned script from your page and execute it. Check the jquery docs.
