I'm trying to append an onChange attribute to an element created through javascript. The following doesn't work. The select is created and has the proper name and id but no onChange..
var sel = document.createElement('select');
sel.name = 'size[' + i + ']';
sel.id = 'size[' + i + ']';
sel.onchange = "changeMini();";
Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.
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 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?
How to focus an element, which is created on the fly,(document.getElementById('id').focus() is not working in IE 7)
View 5 Replies View RelatedI'm creating an img element and appending it where needed. Is it better to set the new img element attributes like this:
var imgEl = document.createElement('img');
imgEl.src = "images/cal.jpg";
imgEl.width = "16";
[code]...
or should I be using imgEl.setAttribute('src', 'images/cal.jpg');
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.
The following:

I have a small HTML form that has a textfeild which when clicked on open a calender, this works fine. I also want to display the selected date in another textfeild using "OnChange". This is what I am working with:
TEXTFEILD
Code:
<input name="startDate" type="text" class="bodytext" id="startDate" size="10" maxlength="10" onclick='scwShow(this,this);' onchange="PrintValues3();" target="_parent._top" onmouseclick="this.focus()">
[code]....
The result2 is then displayed in a textfeild called "result2" but in my case its not.
Is it possible to use both "OnClick" and "Onchange" together?
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.
View 7 Replies View RelatedI'm trying to check to see if a dynamically created element exists BEFORE creating another element of the same exact type...but my if statement at the beginning is not working and another element is just created.

I'm using something along the lines of...
Code:
//next we need to create a row
workingTR = workingTable.insertRow(position+i);
// then I use setAttribute to set the class
[Code]....
the row (tr) is being assigned the class of employee-detail, and I've confirmed this by looking throught the dom explorer. however, it's NOT inherting the CSS formating that is located in a external file .css. I hard coded in a row with the same class 'employee-detail' and it inherited the css formatting.
I'm wondering why my javascript created row is not inheriting the css class formatting.
Code:
.employee-detail {
font-size:10px;
font-weight:bold;
}

View 2 Replies View RelatedI am trying to dynamically create child elements and add a background image before appending it to the parent node.

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"});
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?

Now my problem is that the above function gets called even when the cell has not been clicked, hope am clear enough,
I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
I am echoing some dynamic content into a DIV based on form entries. The content is essentially a dynamic table, with results populated based on the user input. The user can further refine the database results by entering more data into other fields. All of this works fine. What I'd like to add is the ability to click on an <a> tag header on each column to sort by that column. I haven't gotten it to work, so I wanted to try a more simple test. I currently echo <a id='test' href='#'>Click Me</a> into the DIV set aside for AJAX response. I then setup a jquery .click() event monitor to simply alert me when I click on it. If I place this <a> tag in the main portion of the content that is static, I get the alert box. But when I put this into the content of the DIV tag generated dynamically by AJAX, it doesn't fire the alert. Is there something I need to do to 'reload' the page? Is the dynamically added content not part of the document since the entire page isn't reloaded?

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:
For some reason my change() function is only called when the page loads. I'd
much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() {
var new_select = new Selector('tdata','myselect','myid');
var new_select_list = new DataSource("some_list");
new_select_list.addItem(1,"One");
new_select_list.addItem(2,"Two");
new_select_list.addItem(3,"Three");
new_select_list.addItem(4,"Four");
new_select_list.addItem(5,"Five");
new_select.setDataSource(new_select_list);
new_select.formInput("form","input");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
