Trying to add new HTML elements to the document using the jQuery append() function it seems it doesn't add event handlers to the newly created elements.jQuery only seems to add these in Internet Explorer:
I found the bug ticket with similar problem: [URL] but it was closed as invalid. The problem still exists for me. I have the following live event: $("a:not([onclick])").live('click', ajaxLinkHandler); It's not applying to content loaded via $.ajax(...).responseXML which I used to append in the following way:
// withing ajaxLinkHandler var content = $(loadedDocument).find("[component='"+ id +"']"); $(this.contentContainer).empty().append(content);
I have a piece of javascript which does not work as intended. The code is:
var v = document.getElementById('ReportViewer1'); if (v) { v.ClientController.CustomOnReportLoaded = endPoll; }
The endPoll event handler should be added to the list of event handlers for CustomOnReportLoaded. In the code about, it removes all other event handlers and just adds itself. Looking through JQuery i found:
this will add the new event handler to the collection of event handlers already attached to the click event.how do I select the ClientController through JQuery's selectors?
which is the recommended way to bind event handlers to elements. Preferably without giving each of them an id. As far as I know, the "classic" way (<input onchange="...">) is considered deprecated and evil. So what is the jQuery way of doing this?
I'll start off by saying I'm a novice developer. I'm building an mvc application and recently started using the jquery hotness. I've set up a right hand nav and bound click events for collapsible panes. Inside one of those divs (action pane) I've bound click events which will open a modal dialog with a form. The form is submitted with $.post(). Then I've used $.get() to refresh several divs with the new content. Once that happens, all of my links begin to fire twice (collapsible panes and the links in the action pane) in ie8 and the latest firefox but not in chrome. I pulled out all the markup and js and put it on a static test site: [URL].
I want to use .ajax instead of the following js function so that I can use the event handlers to update the DOM after changing the contents of a jQuery UI tab. What happens now is that the DOM only contains the first loading of the JQuery UI tab (fragment-3 in this example). Once the tab is changed by the displayfrag3 function (a table is rewritten with new <td ids>) the DOM doesn't see any new id tags so "on click" functions using the new ids don't work.
My Call to this Function:
My Attempt at using jQuery .ajax:
What is the call statement for this and how do I pass a variable to it?
Could someone show me the correct jQuery .ajax code and explain how to add the success handler to update the DOM.
I have a simple filmstrip that uses getJSON to return data. The data is an array containing two arrays. The first, is the base path to photos. The second is a list of the photo file names. I am trying to loop through the array of photos and set them in divs. Then I need to attach an event to popup a larger view of the image placed in a dynamically generated div containing the image and initially hidden.
So what I am trying to accomplish is: 1. get JSON data from server. 2. get base image path from json data array 3. get list of images from json data array 4. Loop through list of images, prepend base path and assign to hard coded div. 5. create a dynamically generated div with larger version of same image. 6. Attach hover action to cause a mouse-over action on the hard coded div to popup the dynamically generated div containing the larger version of the image.
My issue is that once my code runs, no matter what image in the filmstrip I mouse over I always get a popup with the last image in it. Here is my code: <script language="javascript"> $(document).ready( function(){ $.getJSON("<?php echo site_url('filmstrip/index');?>", function(data){ var dir = data['dir']; var imgs = data['imgs']; var i =0; .....
is there a way to set up a page so that a event handler function is bound to a DOM object and event but it runs _after_ the browser's default action is complete?
I would like to add an event handler to the submit() method on the form. If the form contains an elemant recaptcha, it should show a recpatcha in a modal, and upon completing that recaptcha, assign the entered captcha to that element to be submitted long the form.
Basically, I would be able to attach the code that renders the modal and the recaptcha form in the .submit event handler.
I was just wondering; if we have multiple form.submit() handlers that we attach to the forms. in what order are they executed? and what if one of the handlers return false - will the others still be executed? What if we add the "preventDefault" call in any of these handlers?
Basically - I need to know how I can make sure that this handler I'm attaching to the form does not interfere with any other handlers that may have been attached to the forms submit event...
I'm loading a list of elements into mydiv with ajax, I want them to be selectable so I call the UI plugin selectable after the list has loaded.
The list building function produces this:
<div id='mydiv'> <ul id='mylist'> .... </ul>
[Code].....
The problem is, every time I click the link to reload the list via ajax, I get a duplicate selectable event handler created. Should I be removing the old event handlers before reloading the div ? if so, how?
Everything works, as in selectable still works, and only seems to fire once but I get ever growing memory usage in firefox and an ever growing list of event handlers in the firebug script tab. Eventually firefox starts to crawl and I have to restart the browser.
This is not the way I want to handle events. I checked MSDN and it seems to indicate that the first way should work. Is there something I can do to get the first way (event handlers?) to work in IE5?
I have a script in which a function launched by a START button continuously calculates and writes a value to a text box. The calculation is done in a for loop. In the loop is a conditional that is a global variable, a boolean. If the boolean is true, break ends the loop (or is supposed to!). A STOP button has an onclick function that sets the global variable to true.
What happens, though, is that the function for the STOP button is not executed until the for loop reaches the maximum value set for i. Anyone know how you can get one button to stop a process started by another?
Is it necessary to return a value from the event handlers? For instance, what does the return value in the following code signify? What will be its impact if it returned otherwise (true)?
<html> <head> <script type="text/javascript"> function BodyClick() { // How to access the event object here? alert(window.event.shiftKey); } function WindowLoad() { document.body.onclick = BodyClick; } window.onload = WindowLoad; </script> </head> <body></body> </html>
It does not work in FireFox. How to make it work?
My only requirement is that I need to assign the BodyClick() handler dynamically in script (not statically in HTML). So I cannot use this solution: <body onclick="BodyClick(event)">
I've been teaching myself javascript and I'm a bit confused about the whole events business. I've been reading the Sitepoint book (among a bunch of others) and when it gets to Ch 4 things get down right confusing. They claim that inline event handlers are "so 1998", something I've heard before and then they proceed to write some pretty complex library files to get around the fact that IE <= 7 doesn't support much of the alternative ways of handling events--a familiar enough story. Anyhow, it seems that many many tutorials all over the internet (and countless pages) resort to inline event handlers as the standard. So, I'm confused. I obviously need to know inline event handlers if I intend to work as a web developer even though it's so 1998. Obviously inline even handlers are not quite on par with inline font attributes and transparent gif files despite the language one often hears. Can someone set me straight, and if possible suggest a brilliant tutorial, book chapter, or website that lays everything crystal clear for me?
I wanted to add a onclick event handler to an image in a loop cos I have a dynamic number of images. The problem is I also need to pass a parameter. This works in Opera 8, but doesn't work in IE:
document.images[i].onclick = "javscript: ShowDesc(" + i + ");";
I've been reading this page on accessing event handlers and avoiding the inline ones. Suppose I want to hover over a link and make it display something else, I thought this is what I would put in the <head>:
<script type="text/javascript"> var x = document.getElementById('question'); x.onmouseover = function() {document.getElementById('answer').style.display='inline'} x.onmouseout = function() {document.getElementById('answer').style.display='none'} </script>
The HTML being:
<a id="question" href="#">Question</a> <span id="answer" style="display:none;">The answer is 42</span>
I've reread the article in the link but to no avail, I don't know what is wrong.
<HTML><SCRIPT LANGUAGE="JScript"> function mouseclick() { alert("I was clicked on " + window.event.srcElement.tagName); } </SCRIPT> <BODY <H1>Welcome!</H1> <P>This is a very <B>short</B> document.
</BODY> </HTML>
The above script works fine in IE But not in Netscape 7.2 :((
I have written a script that gets trigered by IE's toolbar button. In this script I would like to asign an event handler to an element of the document currently open in IE. The way one access the document object from a toolbar button script is:
var doc = external.menuArguments.document;
Now assuming the document has an element called TextArea1, the logical thing to do would be:
parentwin.document.all('TextArea1').onkeypress = new Function('window.alert('asdf');');
Which goes compiles and runs, except the event handler does not get triggered.
Another trick i tried is as follows:
var s = parentwin.document.createElement('script'); s.text = 'window.alert('asdf')' s.htmlFor = 'TextArea1' s.event = 'onclick' parentwin.document.scripts[0] = s;
I want to build a table that knows where it has been clicked. I found the following solution myself. Are there better ones?
http://www.student.oulu.fi/~pkarjala/question1.html (tested on Mozilla 1.7.8/Linux)
It sets the event handlers for each TD in the build() loop, including a parameter in the function call that is different for each TD.
The whole thing is a simple example with a table with 5 by 5 cells. If you click on a cell it's supposed to change color. Naturally, my question is one more general terms. How to make big tables that associate various event handlers with various cells, and where you will know exactly which element triggered the event? How to make it simple and maintainable?
I am writing a javascript code that parses dom and finds event handlers attached to mouseover events. Then i will replace the existing handler say B() with my own function say A(). When the event happen and control comes to my function A(), after doing required processing i will call B() as shown below
<a href = "abc.com" mouseover = "B();"link </a>
while parsing i will have (trimmed down version)
var oldHandler = node.onmouseover; node.
function A() { / * my code */ oldHandler.call(this); }
This was working fine as long as B() was a global function. I started getting problems when B was a member function. For eg:
function Alerter(text) { this.text=text; var me=this; this.invoke=function () { alert(this.text); } } var sayHi = new Alerter('Hello, world!');
The web developer would have code like <a href = "abc.com" mouseover = "sayHi.invoke()"link </a>
But this time around, my function A() fails since although i have handler to sayHi.invoke(), it has to be executed in correct context. Other wise "this.text" is giving me error because when i say oldHandler.call(this), i am executing the sayHi.invoke() with the html element being passed as this.
I want to create a HTML Table and correspondingly have 2 buttons. One would be add button and other would be remove button. I have few text boxes where I will fill the data and later on clicking Add these text boxes details would be added to the Table. I am using javascript code to handle the event (on click event handler) Similarly I wanted to delete an entry from the table. This is where I am having a problem. The requirement is: In the table if I click on any row I want that row to be highlighted. I can use any color to highlight the row. Then on clicking Remove Button I want to delete that row that is highlighted. I am unable to solve this as I dont know what event handler to use to perform this action and also how to code for this. I am not sure about the events the HTML table can handle and how the selected row can be deleted.
When I register an event handler directly into the HTML tag everything works fine, but I'm trying to register them from the external JS file where the function is, and that doesn't work at all. I've read that this is called the "traditional method" and that it should work.
I've tried it a million different ways, but what I'm putting below AFAIK is correct... but it just doesn't work. I've tried it in Firefox, IE, and Chrome - and used the "Inspect element" feature in Chrome, and am not getting any error messages.
Here is just a simple example of what I'm trying to do - its extremely basic, I know, but I just can't figure out why it won't work.
HTML:
JS:
(Again, it works perfectly when I stick the onclick="message()" event handler directly into the HTML h1 tag, but not when in the external file.)
I am trying to add onclick event handler to many objects but I can't understand why it doesn't work. To assign event handler I use traditional approach as described in [URL]Heres the code (extract.js):
Code JavaScript: //the class function extract(){
[code]....
I know that both select tags don't have options, but I generate them with JS because they hold sequential numbers and this part has no impact on the problem at hand.Both functions help select next or previous index in a given select tag for greater comfort
