Get XML Back From Event?

Mar 22, 2011

I can use the following code to create an HTML table based on an XML document. However, I would like to pass the onreadystatechange event a callback function (with arguments) to process the XML document. This way I can effectively remove the processing of the document from the event handler.Alternatively, is there a way the event handler can return a reference to the document, so that I can then parse it externally to the event handler?

Code:

function LoadXMLDoc(url) {
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();

Event On Anchor Change(click Back Button) In URL

Jul 26, 2007

We are developing an Ajax based application. In this application the
URL is fixed and as user navigates on the application we will change
Anchor on the URL so that user can bookmark the url and can load the
page on demand.

When user refreshes the page we have no issue in the populating the
page based on the anchor in URL as on load we can capture the
hash(#anchor) and act accordingly.

sample URL: http://www.google.com/somecontext#<anchor>

When the user clicks back button anchor is changing but not able to
know where to get callback.
Is there any event or way I can find when the user has clicked back
button.

Chrome And Firefox Reloads The Page On Back Event?

Jul 23, 2011

We are developing an application with ASP.Net and C#. We have a back button (html link) on few pages, by clicking on back button it triggers the browser back event. So user will be able to see his last viewed results (by going only one level back).

We are calling "window.history.back();" function of Javascript to achieve this, but the problem is that its working fine in IE but not in Chrome and Firefox. Whenever user clicks on the back button, Chrome and Firefox reloads the page from server and execute all the server side events.

What we need is simply go to one step back without reloading or refreshing the page.

Rollover Event Will Pull Back Data For Each Region?

Oct 18, 2011

For the first time in a long time, I've encountered a project with a single image that has many regions.Each region is a polygon, and will bind to a unique rollover event. That rollover event will pull back data for each region.I've thought of using a hidden image in a canvas with a black background, and a different color foreground for each region. Then, mapping the color the proper region data on the backend.I've thought of passing a huge Javascript object with keys that relate to a position in the image, and values that define the region data.Initially, I dismissed the idea of a good, old-fashioned image map, in an attempt to find something sleeker and sexier. But perhaps this is the best solution?

Having A Lightbox Pop Up When A User Clicks The Back Button In Their Browser Rather Than Just Navigating Back

Jul 1, 2011

I'm looking to have a lightbox pop up when a user clicks the Back button in their browser rather than just navigating back. The purpose is to ask a question with a Yes/No answer, and if they click No, I allow them to go back. The only thing I've found anything like this is the onUnload event, but that doesn't prevent them from going back. How should this be handled?

JQuery :: "Back" Button Breaks "mouseout" Event?

Mar 27, 2010

I have bound the "mouseover" and "mouseout" events to an element to swap the background image and create a rollover effect.It works well, except that the image region also contains a link. When the user clicks the link, they navigate to the new page. If they move the mouse, and then click the browser's "Back" button, the original page appears - but with the rollover image still showing because "mouseout" was never called, even though the cursor is no longer over the element.

Back (history.back()) After Refresh

May 29, 2006

I have a webpage popup (lets call it POPUP) which refreshes the opener window (this one we call PARENT) when we close it, saying we want to save data. For this, we use

top.oWndOpener.refresh();

When we don't want to save the POPUP data, we just close the popup and
don't refresh the PARENT. In the PARENT we have a "Back" link which executes a simple

history.back()

The problem is:
If we refresh parent, we need to go back 2 pages, because the refresh
method adds another page to the history. But we have no (easy) way of
knowing in the PARENT if it had been refreshed. With this, our users
are forced to click two times in the Back link.

Is there anyway of going back to the previous page, no matter how many
refreshes happened in the current one ?

JS Call To PHP To XML File Back To PHP And Then Back To JS?

Mar 16, 2010

I have been trying to utilize a pre existing snippet of JS that makes a call to some PHP, where the PHP echo's out the answer, namely a dynamic quick search output, that gains its data from an xml file (which works as expected) and thought I might be able to rework the code to work for my altered purpose (which has been a disaster at every attempt) which is as follows:

1. I have a JS file called call4section.js - JS that has a string (str) value assigned (could be number or a combination of numbers and letters) which is passed to a PHP script called call4section.php.

2. The PHP script takes receipt of the string and finds a match within an XML file for the entry under <reference>.

3. The XML file has a format as follows:

<pages>
<note>
<section>value</section>

[code]....

And well, I dont seem to be able to get any further forward with it. Effectively, I can echo out the $reply (if it worked I think), but my stumbling block is sending the starting string, with the JS expecting some reply sent from the PHP.

Back - Forward Browser Button For Iframe - Bring Back/forward Iframe Or Top Window?

Jan 24, 2011

I am wondering how Back, Forward browser button works for iframes. Does it bring back/forward iframe or top window? I remember I had before a problem because I wanted to bring back iframe and not top window as it did. But today I tested my Facebook app and was surprised to see it works as I need which means it brings back/forward iframe window and not top. Is it possible that Facebook has some javascript code which does that or is this normall behaviour?

JQuery :: Live() Event Doesn't Refresh The Class Of The Event Which Was Changed Dynamically

Jul 4, 2009

I got this problem with live() event.I have used it as follows.

$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});

I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.

Having Trouble With Event Listener: Detect Iframe Close Event Fromparent

Apr 3, 2007

I have an iframe that includes a button:
<input type="button" value="close this window" onclick="window.close();" >

I would like to detect the iframe close event from the parent window, I
was using this code but I did something wrong because the temp function
is fired every time the parent page loads:

function temp(){
alert('the iframe was closed');
}
function setup(){
var myIFrame = document.getElementById("iframe1");
if (myIFrame.addEventListener) {
myIFrame.addEventListener('onclose', temp(), false);
}else if (myIFrame.attachEvent) {
myIFrame.attachEvent ('onclose',temp);
}else{
myIFrame.onclose=temp();
}
}
window.onload=setup;

JQuery :: Event.stopPropagation() Is Preventing A Live Event On A Child Element

Jul 6, 2009

As far as I understood, stopPropagation() is supposed to stop events bubbling 'up' though the element tree (through parent elements). Eg. If I use stopPropagation() on a click event on an anchor element in a list, the event would not be triggered on the list. In my code I have a popup div, that needs to have stopPropagation(), as a click on the document (everywhere other than the popup) will hide it. When I add an element to the popup that has a live click event, the live click event is never called, even though it is a child element of the popup. Shouldn't the live click get called first? If I remove the stopPropagation all is well.. some code:

$('#a_test_link').live("click", function(e){
e.preventDefault();
alert('done!');
});

[Code].....

JQuery :: OnChange Event - Web Application - Each Blur Event Makes A Call Webserver To Store Value Of Textfield

Jan 21, 2010

I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.

The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.

I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.

Sample code (IE 8 on Windows 7 computer):

script:

HTML:

JQuery :: Triggering Event When Checkbox State Is Changed By Another Event?

Jun 27, 2011

Is there a generic way to fire an event when the state/value of a checkbox is changed by another event - i.e. not a user action. In this scenario, I have a set of checkboxes with a "select all" checkbox. I have the code written such that checking or unchecking the "select all" checkbox updates the state of all of the checkboxes below.

The extra requirement here is that some of these checkboxes have "children". So, when you check one of these, its children are automatically checked as well. So, what I need to do is check the main "select all" checkbox, which would then check all of the immediate children, which would then check all of their immediate children. I tried both an onchange and onclick event, but neither seem to be firing.

<head>
<script src="/scripts/jquery/jquery-1.3.2.min.js" type="text/javascript"></script>

this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.

JQuery :: Triggering A Click Event Via (event.button != 0)?

Apr 8, 2010

I have an object that has a click event I'm trying to trigger. However in the click event I have the following if statement:

if(event.button != 0){return true;}

This if statement allows right clicks to go through and activate but it also prevents me from triggering the event. Any ideas on how to prevent this? If I remove the if statement from the first click function everything works as intended.Here's my example code based off of the trigger event examples:

<!DOCTYPE html>

Onclick Event Expands DIV / Will Onmouseout Event Close?

Jan 9, 2009

currently on our site we have and expanding <div> that responds to both the onmouseover and onmouseout events. It works wonderfully.

The UX people now would like the expanding <div> to open with the onclick event and then as soon as the mouse leaves the expanded div, it would close. I have tried using the onmouseout event in conjunction the onclick event but it does not work (the div persists).

Event Groups - Attaching Event Listeners With A Namespace
