Am new to javascript and am having this problem;
//Some other code
//Here I create an input element of type text and assign a onclick event property
var quantityTxt = document.createElement("input");
quantityTxt.type = "text";
quantityTxt.onclick = calcAmount();
[Code]...
Now my problem is that the above function gets called even when the cell has not been clicked, hope am clear enough,
I have a table with a date field in each row:
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?
hi everybody, didn't find this using the search :( this is my problem:
i create a dom element dynamically (<span>) and want to assign a class
attribute to it such that it has some css style, this works in ie, but
not in firefox :( here's the simple code:
<div id="somediv"></div>
var div = window.document.getElementById("somediv");
var span = window.document.createElement("span");
span.innerHTML = "span";
span.attributes.getNamedItem("class").nodeValue = "span_class";
div.appendChild(span);
so this works well in ie6, but firefox gives this error:
Error: span.attributes.getNamedItem("class") has no properties
if i run this code on a statically defined span (in the html file),
where a class attribute already is set:
<div id="somediv">
<span id="spanspan" class="">
</span>
</div>
changing the class to "span_class" works both in ie and firefox.
how can i fix my above code such that it works in both browsers? it
seems that on newly created dom elements the class attribute isn't even
there (to change it), how can i create it, and then change it?
I have a text box im dynamically adding to the dom created with this line of code
When I try to get the value of the text box by referring to its id. I get an "undefined". I can get the value if I use plain javascript.
After loading a HTML fragment using AJAX, I can not select the newly embedded elements using the $("#id") notation. document.getElementById works fine though.

I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
Imagine an element with a specific selector getting created and then once the element exists and the selector is applied, all of the behaviors are applied (events, styles and plugin methods).
[Code]...
This would be similar to the live event where a function is applied to the specified event of all selectors even if they do not exist yet. The only difference is that the event is not the typical peripheral driven event (mousemove, keyup,etc) but would be fired once that element exists in DOM.
My requirement is to submit html form with Attachment filesfor a web based email application.I have used javascript to achieve Attach more files functionality.When user clicks on ttach more files link, following HTML is dynamically generated using javascript:
<input type=file name=some_namesize=/>
The Javascript code is:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;

I have a page where I do:
var e = document.createElement('img');
e.src = "myimg.jpg";
e.id = "i";
In some functions I need to get the html code of e, i.e. "<img
src="myimg.jpg" id="i">. Is there a method like "getHtmlSource" of the
element?
Am creating text input element dynamically using DOM and i want to pass a event when onchange event is triggered.. Am able to assign the function to it but failing to pass the event..
View 2 Replies View RelatedI have live focusin and focusout bound for form validation. But if some content is created dynamically (either via a templating system or via ajax) it doesn't seem possible to initialise those elements (i have placeholder text that i might want to add inside the element for example).
Is there an event that is fired when an element is added to the dom?
Code:
This is a trimmed down version of my problem, '.myElement' gets duplicated on double click. In '.myElement' is content and a close button that when clicked removes itself.
The problem is "newly" created elements don't get the the dblclick or the child 'a.close' click events. i know i can double the events and re apply after the element is created but in my real version there is WAY more going on in each of these events and i don't want to create all that redundant code. i guess i can pull all the actions out into functions and bind after creation but even that is a little messy, is there an apply events feature in jQuery or something?
like:
Code:
I'm creating some rows and cells in a table with javascript. I'm then trying to select these cells individually by id, but jquery can't seem to find them. It always returns length 0. The jquery code is, I believe, executing after the cell creation, so I would expect them to be in the DOM already. I can bind the click event to each cell by selecting the cell's class. Why can I select the class, but not the id? It would be nice to be able to do this rather than iterate through each cell in the class.

I hope I got the title right, anyway, I have a button element as shown below;
//Edit Image (Edit the current Item)
$("img[title='Edit']").click(function(){
var ajaxTranId=$(this).attr("id");

for (x=0;x<=10;x++) {
var tempID = 'elementName' + x;

I have a function that dynamically creates a new div, part of the function looks like:
root = document.getElementById('rootbox2');
var oDiv=root.appendChild(document.createElement("div"));
with(oDiv){
id=ji;
className="workshopRow";
setAttribute("attending","");
setAttribute("attending_count","0");
}
var oText = oDiv.appendChild (document.createTextNode(""));
var oDiv1=oDiv.appendChild(document.createElement("div"));
with(oDiv1){
className="workshopName";
}
var oText = oDiv1.appendChild (document.createTextNode(""));
var oSelect=oDiv1.appendChild(document.createElement("select"));
with(oSelect){
name="select_"+ji;
id="select_"+ji;
className="workshop";
onchange="calc_subtotal("+ji+")";
}
var oText = oSelect.appendChild (document.createTextNode(""));
var oOption=oSelect.appendChild(document.createElement("option"));
with(oOption){
value="12";
setAttribute("price",10);
}
What I am looking to do is add an onchange event to the select element, not sure if i have programmed it correctly but it does not seem to work.
I have tag something like
<div class='abc'>
using jquery i want to change the class dynamically.
i saw the jquery reference, it has something hasClass, but i donot see addClass.
Im sure this is a very silly problem, but im trying to create a li and then set its class in jquery but it doesn't seam to be working
Code:
var listid = field + "_errormessage";
if (errorMessage != "")

I came up with some code to load javascript files dynamically. But I've got problems..
When the script element is dynamically added to the head section of html, i think that the document.ready event fires once again and therefore the code sort of runs twice.
In the html page I call this method:
In the script test.js I have the function SayHi():
The SayHi method never gets called and alert('begin') & alert('getScript') get called twice in this sequence:begin begin getScript getScript.
I have two div elements (both dynamically created, one within the other). The parent div has an event attached to it:
contextmenuDIV.onmouseout = function () {doSomething()}
for example. However the onmouseout event will fire when you mouseover the child div as (of course) I am technically leaving the div layer (despite it being the parent).
Is there anyway to cancel this? I've read all about bubbling and all that, but it's just confusing me even more!
Anyway, at all, to allow me to have divs within another div element but only allow the event to fire for the parent!
why I should use the dom level 2 event handling over inline events like ...
Code HTML4Strict:
<a href="http://www.yahoo.com" onClick="myFunction()">click me</a>
I work in a team of developers and our pages are dynamically created using Java.I can at any moment change the inline JS across a site due to this so changes are easier then if the site was just static HTML.As far as reasons to use dom 2 over inline, I looking for something beyond:
it separates behavior from html
it is a best practice
it is the 'modern' way of doing it
I need facts that explain why it is a best practice or why 'modern' is better like : you can only assign one function action to the event.That was just an example which I see but is not true to me.I can either assign multiple functions to it like:
Code HTML4Strict:
<a href="http://www.yahoo.com" onClick="myFunctionA();myFunctionB();myFunctionC()">click me</a>
or I can call my functions from a single function call like
Code HTML4Strict: <a href="http://www.yahoo.com" onClick="myMultiFunctionCall()">click me</a>
and then have a function defined before the inline call like
Code JavaScript:
function myMultiFunctionCall()
{[code].....
Here the second statement overwrites the first.By the way, here is a con for using dom and to me a big one considering debugging: you can't see what event handlers are assigned to what unlike inline where it is obvious because it is in the page. see http:[url].......
I am having a list (ul) in which a mouse over will populate its sub categories as list under that(like tree) and so on. My problem is, when passes mouse over a 2nd or 3rd level element, 2 mouse over events will be fired (The actual one and its parent) The sample code is given below
HTML Code:
<ul>
<li>
Root[code]............
I have a question about event handling in javascript.Let's say I have 3 divs, directly in the body of an html document.
<html>
<body>
<div id="div1black"></div>[code].......
Each of those div's is positioned differently using css, as displayed in the image below: Each div has an event listener for the click event.In the image above I marked a point. If the user would click on that point, are all 3 event listeners supposed to fire? As I understood it, there's a capture and a bubbling phase, but these only go down through and up from the ancestors of the target right? And none of the div's are ancestors of eachother, they just happened to overlap because of the css position.
How would I let all registered eventsHandlers be fired whenever a user clicks on overlapping HTML elements? (so the eventHandlers for each of the 3 div's should be fired).
I have a document with a parent element that has mousedown,mouseup and mousemove events registered to it. The parent element has some child elements as well. I observe inconsistent behaviours between browser types when I hold the mouse button down, move the pointer and release the button.
ie7 - mouseup fires when over a child or parent
op9 - mouseup fires only when over the parent
ff2 - mouseup fires only over a child or parent but only if the pointer has moved since the mousedown occured
Because much of the talented JS community doesn't frequent the 'looking to hire' marketplace boards, I wanted to link to my post looking for help in understanding fully a group of functions I would like to use. While much of this I understand, along with some of the OOP principles used, there are some hang-ups I'm running into. Therefore, I'm looking for someone to walk me through the functions and help me understand the logic behind it. And since time is money, especially for those who are more skilled, I would rather respect this and pay for the conversation.
Further, if the person who takes up the task doesn't object, I will document the functions use for the community to benefit, since these are public boards. Of course, giving full credit to the original writers and the person who helped me understand.
