Small rules and special cases for js to dynamically call css attributes

Source: Internet
Author: User

I saw a good article about css attributes called by js just now. (pai_^) is good! Forget it, and summarize it to your blog! (* ^__ ^ *) Xi ......

 

1. for css attributes without hyphens, you can directly use style. attribute name.

 

For example, obj. style. margin, obj. style. width, obj. style. left, obj. style. position, etc.

 

2. for css attributes that contain dashes, remove each dashes and replace the first character after each dashes with uppercase letters.

 

For example, obj. style. marginTop, obj. style. borderLeftWidth, obj. style. zIndex, obj. style. fontFamily, etc.

 

 

Because float is a reserved word in Javascript, how can I write float in a style sheet in js?

 

We cannot directly use obj. style. float. This operation is invalid.

 

The correct method is: IE: obj. style. styleFloat, other browsers Mozilla (gecko), ff, and other styleFloat: obj.style.css Float.

 

Let's give an example for your understanding:

 

<Div onclick = "alert (this. style. float );

This. style. float = 'left ';

Alert (this. style. float); "> Test 1 </div>

<Div onclick = "alert (this. style. float );

If(this.style.cssfloat?#this.style.css Float = 'left ';

} Else {this. style. styleFloat = 'left ';

} Alert (this. style. float); "> Test 2 </div>
