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');
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; .....
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?
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' }
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)?
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.
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.
View 2 Replies View RelatedHow would you access information about various attributes of an element with javascript?
View 2 Replies View RelatedI'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.*?
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:

I have a huge form with a lot of data.
There is a table that data in it I need to display on a print screen (of course this data isn't being displayed in the regular table).
So, I put the display text in a span tag.
So, this is how each item will look:
I need a way to grab all spans on the page that have the attributte of "printData" and grab that text inside that attribute and print it out.
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 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();";
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:
jQuery('<p><a>jQuery</a></p>');

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;
}

I have a problem, I have a table which dynamically create <tr> elements with a unique numerical id, this is created on a while loop from a database statement, when I click on a hyperlink on each <tr> I use this:

So in this way, I'm sending the unique code (codigo) and I fadeToggle the <tr> identified with that specific id, it works, no problem, it display with one click, hides with another one, BUT, now I need that, when you click on a hyperlink, if any other <tr> is being displayed at the moment, close all of them, and open the clicked one, is there any way I can do this?
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?
