Hi Experts,

I can't seem to find any information regarding the type of tag used in the following code snippet.

Would someone be kind enough to explain the syntax please?

Many thanks
$("<a/>").html("<span class=\"verdana\">&laquo; &nbsp;</span>Prev")

If you pass a HTML string to jQuery function, $(), it just generates the DOM element(s), similar to JavaScript createElement(), but you can pass any HTML string with many elements in it.
You need to insert it in the DOM tree in order to see it, using one of jQuery methods like append(), prepend(), insertAfter() and so on.

And... html() does not insert, it replaces the innerHTML.

Hi, thanks for your post

This does work, I just wanted to understand the syntax a little better.

If you take a look at the following link you'll notice the pagination at the very top of the page. Click a digit or the next button and the "Prev" link appears.

I've added a little more of the script below to help shed some light but due to NDA I can't release the rest, apologies for that.

Thanks again



$("<a/>").html("<span class=\"verdana\">&laquo; &nbsp;</span>Prev").attr("href", "#").live( 'click',(function() {

				func_tool(tool,tableid,(currpage-1));

				return false;

			})).appendTo("#pagination").wrap("<span class=\"prev\"></span>");

Ah

it was the appendto we missed

$("<a/>").html("<span class=\"verdana\">&laquo; &nbsp;</span>Prev").appendTo('body')

That makes sense.

So jhp said it:

$("<a/>") // create a link
.html("<span class=\"verdana\">&laquo; &nbsp;</span>Prev") // replace the innerHTML
.attr("href", "#") // set the href to #
.live( 'click',(....) // attach/bind an event handler to all current and future links
.appendTo("#pagination") // append this link to the object with id="pagination"
.wrap("<span class=\"prev\"></span>") // wrap the link I guess

I would expect the wrap to come before the append


<div id="pagination" class="nicepagination center">

  <span class="prev">

    <a href="#" style="">

      <span class="verdana">« &nbsp;</span>Prev

    </a>

  </span>

.

.

.

</div>

I think that that live() has no merit, but possible side effects.
Just regular .click(function () {... would suffice.
