A new challenge is to select only one particular element from a set of similar or identical elements.
jquery provides filter () and not () to do this.
Filter () is able to refine the element to only those that satisfy the filter, not () on the contrary, he removes all the conditions that satisfy the condition. -

Split ():
Program code
<script type= "Text/javascript" >
$ (document). Ready (function () {
$ ("input[@value =btn1]"). Click (function () {
Split with ￥
Alert ($ ("Span.sale"). Text (). Split ("￥") [2]+ "| |" +$ ("Span.sale"). Text (). Split ("￥") [1]+ "| |" +$ ("Span.sale"). Text (). Split ("￥") [0]);
});
});
</script>
<body>
Get price 120:<input type= "button" value= "BTN1" ><br>
<span class= "Sale" >
Out sale:￥160<br/>
Deal price:￥120</span>
<!--
Apply split to solve this problem. An example of split is given below:
msg = "2007/10/01";
msg = Msg.split ("/");
Alert (msg[2]);
He would divide the msg into an array of 3 blocks, which would then be easily accessible.

Help: Filter in Firefox error, do not know whether I write wrong?
var stext = $ (data). Filter (' #content '). html ();
Data is the content that is retrieved through Ajax, I want to filter, as long as the contents of the content of the ID is the part.
This writing in IE all normal, do not know why in Firefox does not work, with Firebug to find errors, the hint is the 1521th line of jquery-1.2.1.js "f = (' false| | function (a,i) {return ' + F + '} '); " This paragraph has a problem, do not know whether it is a bug, do not know how to deal with. Toss n long, almost collapsed! No way, I just contact jquery, or a small rookie.
This problem has been solved by itself!
I do not know if anyone has the same problem, but I would like to share their experience!
When filtering with filter, fixed data such as march.hu said that (var data = "<p> The first paragraph </p><p id= ' second ' > second paragraph </p>";), this does not matter, However, when using AJAX to retrieve dynamic data for filtering, you must specify both the label type and ID to filter correctly, or you will get an error in Firefox.
Error: var stext = $ (data). Filter (' #content '). html ();
Correct: var stext = $ (data). Filter (' Div#content '). html ();
