Using c# .net
Hi, I´m trying to do a postBack on a unload event, in google chrome the currently script works fine
window.onbeforeunload = function () {
__doPostBack('<%= pararThread.ClientID.Replace("_", "$") %>');
}
for internet explorer and other, I had to use Jquery
$(window).unload(function () {
__doPostBack('<%= pararThread.ClientID.Replace("_", "$") %>');
});
So far, so good, but, only in Firefox, the page is doing the postback, but it no longer goes to another page, Example, if a click on a Link, it will fire the event unLoad, it will do the post back, but the page will refresh and will not reach the link.
Ps: I´m doing this postBack because I need to stop a Thread that os runing on the server.
Just add this code snippet in your .master page or any other appropiate page just before the </body> tag:
<script language="javascript" type="text/javascript">
<!--
function __doPostBack(eventTarget, eventArgument) {
var theform;
if (window.navigator.appName.toLowerCase().indexOf("microsoft") > -1) {
theform = document.aspnetForm;
}
else {
theform = document.forms["aspnetForm"];
}
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->
</script>
Replace 'aspnetForm' with your own.

My app runs inside an iframe in a wrapper page. When the wrapper page loads, the source for the iframe is set like this
<script type="text/javascript">
var frameSrc = 'myApp.jsp';
$(document).ready(function() {
loadFrame(frameSrc);
$("#iFrm").height($(window).height() - 175);
$(window).bind('resize', function(){
$("#iFrm").height($(window).height() - 175);
return false;
});
$("#adminLink").click(function(){
frameSrc = 'myAdmin.jsp';
loadFrame(frameSrc);
});
return false;
});
function loadFrame(src){
$("#iFrm").attr('src', src);
}
</script>
And this loads and runs just fine, but then I've got the admin link on the page that is intended to load a different page into the iframe and it has an event handler inside the document.ready function.
The issue that I'm encountering is that the myAdmin.jsp is loading and then the original document.ready script, in the wrapper page, is running again - completely with the original frameSrc value. It seems as though by changing the iframe source, it's triggering a reload of the entire wrapper page and the original iframe source. Has anyone seen this? Am I missing something obvious?
I got an answer to this question while working through various possible solutions. The problem turned out to have to do with adminLink. The href value was empty, which appears to have directed the browser to reload the current page (the wrapper). When I put javascript: return false; in the href my issue resolved.
<a id="adminLink" href="">Administration</a>
vs
<a id="adminLink" href="javascript:return false;">Administration</a>
I have a jquery to show links in a div without reloading page:
jQuery Code:
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function(event) {
// Prevent default click action if javascript is enabled
event.preventDefault();
//load the content of the new page into the content of the current page
$("#content").load( $(this).attr("href") + " #content");
})
});
</script>
everything is fine and working, but this is so simple! how i can add a loading image before content loading in this code?
and second question, is there any way to show a new page link in address bar after loading?
You can use the call back function to remove the loader.
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function(event) {
// Prevent default click action if javascript is enabled
event.preventDefault();
//load the content of the new page into the content of the current page
$('#loader').show(); // Show some hidden loader on the page
$("#content").load( $(this).attr("href") + " #content", function() {
$('#loader').hide(); // Hide the loader when it completely loads the given URL.
});
})
});
</script>
For your second question this should be the answer. Change the URL in the browser without loading the new page using JavaScript
I am using validation engine from http://www.position-absolute.com/ site.
The validation is applied on the div tag which is opened as popup on parent page.
Issue : when error message is shown on a control, it is appearing behind the div.
Search to similar issue suggest the usages of z-index, but how to control the z-index of error message poping from validation engine? Giving high number to div z-index:99999 did not work.
Please help
just change your script as
<script type="text/javascript">
$(function () {
$(".primary").click(function () {
$(".formError").remove();
});
$(".close").click(function () {
$(".formError").remove();
});
$("#yourformid").submit(function (ev) {
ev.preventDefault();
var validForm = $("#yourformid").validationEngine('validate');
$(".formError").css("z-index", 15000);
if (validForm) {
$("#yourformid").submit();
}
});
});
</script>
it works fine
I have an image that is in my apex application with the id tag of submit_button. I want to display an alert when the user tries to click this image but for some reason nothing is happening. In my header on the page I have this code
<script type="text/javascript">
$(document).ready(function() {
$('#submit_button').click(function) {
alert('hi');
}
});
</script>
Any ideas?
I don't know why that doesn't work (it doesn't work for me either, I just tried), but it is very simple to do via a dynamic action with the following properties:
Event = click
Selection Type = DOM Object
DOM Object = submit_button
"True" Action = Execute Javascript Code
Fire on page load = (unchecked)
Code = alert('hi');
How can i catch the "onblur" event of my htmlbox textarea?
I want to be able to get the htmlbox content when it's onblur..
Thank's In Advance.
Try this code, it loops waiting 1 second until htmlbox creates the iframe, then it adds a .blur handler to the iframe, I found out the iframe's id by using IE8's Developer Tools, by clicking on the arrow icon in the developer tools and clicking the box you can see how HTML looks after the page loads and javascript processed. if($("iframe").length) is true then then htmlbox has created the iframe and you can attach the .blur event handler.
<script type="text/javascript">
$(function(){
var check = function(){
if($("iframe").length){
$("#hb_html").blur(function(){
alert('Blur has occurred!');
});
} else {
setTimeout(check, 1000)
}
}
setTimeout(check, 1000)
});
</script>
This example demonstrates:
<script type="text/javascript" src="jquery-1.5.min.js"></script>
<script type="text/javascript">
$(function(){
$("#bar").blur(function(){
$(this).text("I have been blurred.");
});
});
</script>
<textarea id='bar'>foo</textarea>
Make sure the file jquery-1.5.min.js is in the same folder IF you use the example above.
You can read up on the .blur event at http://api.jquery.com/blur/
It receives a function as an argument and executes it when it becomes blurred.
