Set Attributes On A Created Element?

Jan 24, 2009

I'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');

Flashplayers Created Do Not Obey Style Attributes Of Parent

Oct 26, 2009

I'm having trouble with some flash players that don't abide by the style attribute of the div they're created in using Javascript. When the flash-players' source is hard-coded into the page source they render fine, but the more players, the more bloat as you can see in the source of the original page.

Example:
[URL]
Original Page with old code:
[URL]
The problem code:
<script type="text/javascript">
function clv(obj){
var strst="[URL]";
var strnm=obj; .....

Set Dom Element Class (if Element Was Dynamically Created)

Jan 25, 2006

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?

JQuery :: Get All Attributes Of An Element?

Sep 6, 2011

If I have the following hyperlink :

<p><a href='page.htm' id='foo' class='bar' alt='alt text'>click</a></p>

I know that I can get (eg) the href attribute via $('a').attr('href') BUT I would like to do the following :

get *all* the attribute names and values without knowing anything about the attribute names and values in advance (or even how many there are) - something like a loop and $('a').(attribute name, attribute value). I suppose they would best be placed in a JavaScript object as a set of name/value pairs eg { href: 'page.htm', id: 'foo', alt: 'alt text' }

Array Element Attributes

Sep 9, 2006

var fdot;
fdot[0]=new Image();
fdot[0].src="images/5dot0.jpg";
fdot[1]=new Image();
fdot[1].src="images/5dot1.jpg";
fdot[2]=new Image();
fdot[2].src="images/5dot2.jpg";
fdot[3]=new Image();
fdot[3].src="images/5dot3.jpg";
fdot[4]=new Image();
fdot[4].src="images/5dot4.jpg";
fdot[5]=new Image();
fdot[5].src="images/5dot5.jpg";

function overlay(e,num) {
var targ;
if (!e) var e = window.event;
if (e.target) targ = e.target;
else if (e.srcElement) targ = e.srcElement;
if (targ.nodeType == 3) // defeat Safari bug
targ = targ.parentNode;
targ.src = fdot[num].src;}

Overlay is called as an onmouseover event from an image's map AREA tag, sending event and a number. FF's JS Console spits out that fdot has no properties. Ideas? Better ways to do this effect (replace the image depending on which area of the imagemap is mousover'd)?

Onclick Get All Element Attributes?

Oct 13, 2011

I need a function that can return any elements attributes when clicked.

Mostly this is for getting link data. But there are a few elements in the Google Maps javascript api that I don't know what type of element they are.

Once I am able to get any clicked elements attributes, I will execute the data in ajax to log the data in my database. Once I have an idea of what needs to be and doesn't need to be tracked, I will apply filters accordingly.

JQuery :: Add Attributes / Extend Element?

Aug 13, 2009

When you need for a certain element (say a text input box) to remember some data, what is the best way to do this? Can you extend the input box object with jquery? Right now i've been storing it in the rel tag $('#testInput').attr('rel','extrainfo') it just seems like there should be a better way to do this.

Working With Element.style Attributes

Nov 1, 2005

I'm developing a web-template editor for a client, and they want it to update the changes in real-time using javascript. So, in other words, when a person selects a different background image, I use:

document.body.style.backgroundImage="url("+bgimg+")";
Well, I've run into a little problem. I can't seem to find any manual on what comes after style.*

So far, I've seen style.color, style.backgroundImage, style.backgroundRepeat, style.backgroundColor. But, I'm looking for something that can control text-decoration, font-weight and a:hover

Does anyone no where I can find a list of all properties support after style.*?

Change Attributes When Removing Element

May 9, 2011

I have a JavaScript file which Adds and Removes elements when you click a button.

Adding stuff is okay, but removing elements is more complicated.

When you add an element you also add id=x. Each time you add an element x goes up one. For example if I click "add element" 5 times it would be like this:

HTML Code:

If I wanted to remove the thrid element then I would want the following divs to replace it, for example it should look like this:

HTML Code:

I can't figure out how to do this, here is what I tried but it won't work

JQuery :: After Element Is Created Event?

Aug 12, 2010

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.

Created Element Not Inheriting Css Class Formatting?

May 30, 2010

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;
}

JQuery :: Grab Element Created With Append Function

Jul 27, 2011

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"});

JQuery :: 1.4 Live And An Event To Be Notified When A New Dom Element Is Created

Jan 20, 2010

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?
