JS function arguments and get CSS style method

function parameter, when the number of arguments is variable, you can use arguments

Arguments.length= Number of arguments

To get a CSS style method:

The getComputedStyle () method----> Gets the computed style of the computer (the final style after several changes), IE 6 7 8 is compatible

Style. Properties-----> Operations are element inline styles, resulting in attributes that are inline styles

Currentstyle-----> Standard Browser not compatible

Attention:

You cannot get a composite style. Example: Backgroud:url () color ....

A single style should not be used for judgment.

Do not have spaces

Do not get a style that is not set: incompatible

Dealing with compatibility cases:

if ($ (' Div1 '). Currentstyle) {

$ (' Div1 '). Currentstyle.width;

}else{

getComputedStyle ($ (' Div1 ')). width;

}

Using the function:

function GetStyle (obj,attr) {

Return Obj.currentstyle? Obj.currentstyle[attr]:getcomputedstyle (obj) [attr];

}
