With jquery how to achieve a column to achieve column discoloration, and then click on another column also discoloration, but the original change back to the primary color, I have the array of a (1,2,3, I cycle through the output a value.)
Copy Code code as follows:
<ul>
<li><a onclick= "Show ();" ><b>a[0]<b><a></li>
<li><a onclick= "Show ();" ><b>a[1]<b><a></li>
<li><a onclick= "Show ();" ><b>a[2]<b><a></li>
Click 1,1 discoloration, click 2,2 Color, but 1 will change back to the original color. I show the method implements other functions.
Here's the code for my preliminary interview.：
HTML Code:
Copy Code code as follows:
<style type= "Text/css" >
. clckclass{color:red;}
</style>
<script type= "Text/javascript" >
$ (' ul Li a '). bind (' click ', function () {
$ (' ul Li A:not (this) '). Removeclass (' Clckclass ');
$ (this). addclass (' Clckclass ');
});
</script>jscript Code:
<style type= "Text/css" >
. clckclass{color:red;}
</style>
<script type= "Text/javascript" >
$ (' ul Li a '). bind (' click ', function () {
$ ('. Clckclass '). Removeclass (' Clckclass ');
$ (this). addclass (' Clckclass ');
});
</script>
In the above code, the style ' clckclass ' may be used on other elements, using $ ('. Clckclass '). Removeclass (' Clckclass '); Removes the Clckclass style from the element used in the Clckclass style on the screen. This is obviously not the result we want, we just need to move out of ul Li a clckclass style. But then it turns out that the code in the above the only point is that the clckclass can only be used in these several tags, if other use, it may affect the effect, I was not considered, I only considered the Clckclass this style only applies to the above situation, then according to this can make a small change As follows:
JScript Code:
Copy Code code as follows:
<style type= "Text/css" >
. clckclass{color:red;}
</style>
<script type= "Text/javascript" >
var Removeclassa = $ (' ul Li A.clckclass ');
$ (' ul Li a '). bind (' click ', function () {
Removeclassa. Removeclass (' Clckclass ');
$ (this). addclass (' Clckclass ');
Removeclassa = $ (this);
});
</script> this writes that the node that owns the class of Clckclass is saved in the variable, and the next click can be done without a traversal, faster.
