My code is this:
Code:

In a few words it creates a button which when it is clicked it launches the add_text script. Add text script creates a text element for a form and puts a random value for the textbox. Textbox also takes a name which is of array type name="txt[]". Also form has the post method.
When I press e.g. 4 times the add text field button 4 text boxes are added. But when I click the submit button I get a result of 1 instead of 4 when the print count($txt) is executed. Copy paste the code to see the problem.
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.
I 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?
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,
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 have written some dom code to create a list of divs, each with it's
own id. I want to set the onmouseover and onmouseout events to
highlight the div when the mouse is over it. However I cannot use the
method below because oDiv.id is always set to the last div I create -
so the last div is highlighted regardless of which div I am onmouseover
This must be a common issue, how do I go about fixing it?
I can have a separate function which takes event.srcElement and tracks
back through the parent elments until it finds a div with an id
starting with "entry_" but I was hoping for an easier option.
Is this something to do with closures?
Here's a much simplified example :
for( nIndex=0; nIndex<aEntries.length; nIndex++)
{
oEntry = aEntries[nIndex];
oDiv = document.createElement( "div");
oDiv.id = "entry_" + oEntry.uniquename;
oDiv. {document.getElementById(
oDiv.id).className = "hover";};
oDiv. {document.getElementById(
oDiv.id).className = "";};
oBody.appendChild( oDiv)
}
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?
I am not completely new to JQuery, but not a beginner either. Anyway, I want to do some advanced stuff like creating everything dynamically with JQuery. So here's the rough concept:
Step 1: Information get's collected
Step 2: Information will be written in divs, the divs will get an ID and will be displayed with .append()
Step 3: Setting css-propertys with the div's ID.
I can't grab the div which I created with .append.
Actually I can't access anything which was created with .append - for example if I want to get an .attr() - I can't do it with these elements. Is there a workaround or am I wrong:
$("#site").append("<div class='container' id=' " + containerId + "'>" + containerId + "</div>");
$("#" + containerId).css({
"left" : positionX + "px",
"top" : positionY + "px",
"background-color" : "#F000FA"});

Ok this is my first day with JQuery, so I know I'm probably asking a stupid question; But, given the following code, how do I pass a parameter when I set the function for an event.
var url = $("#deleteBlog").attr("href");
$("#deleteBlog").click(deleteBlog);
I have a custom function:
function myFunc(o){
o.css("color","red");
}
and then I have a jQuery event like this:
$("myButton").mouseenter(function(e){
myFunc(this);
});
How can i pass the element to the custom function and then do all the jQuery manipulation from there?
How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

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?
The client is a realtor with a non-standard intranet which is a "conferencing" system with a very interesting built-in web server (FirstClass). They post property listings to conferences as email messages, with the property address as the message subject. I'm trying to place the addresses on a Google map using the goMap() plugin.
I've figured out how to read the conferences and extract the addresses to a web page, either as well-formed JSON or as a string formatted exactly as one would hard code it for goMap, but when I attempt to initialize a map it either rejects it with an error, or ignores it and gives me the default map (of Europe). If I copy/paste the server-generated string into the init function it works just fine.

how to get that info into my initialization function dynamically?
One of the problems with IE's attachEvent is that "this" will still refer to the window, as opposed to the object that called the function. Example:
Code:
function alertName() {
alert(this);
[code]....
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.
I'm using the Microsoft Virtual Earth Version 1 Commercial Control.
I want to make it so you can click on a pinpoint that's plotted on the
map and all mouse events are passed to the map so that the user can
click anywhere on the map (including the pin points) and drag/zoom the
map around.
For those of you who haven't used Virtual Earth:
Basically, there are a bunch on absolutely positioned Div elements. I
basically want to pass all mouse events from one absolutely positioned

it.
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?

I'm trying to remove an element that was created after the DOM was loaded using append().
I append the element to a div when the checkbox is checked. But if this checkbox is then unchecked I want to remove the element, but couldn't figure it out thus far.
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.
