Special Writing of css float in Javascript

Recently, I used a program to set the float attribute of css in js. I thought it was the same as the usual method. It wasn't. First, let's take a look at the method of operating css attributes in js:

Different from css:

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.

I think most front-end developers are familiar with this rule. It is really special to use js with a special attribute in css.

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>
