From a previous quest we asked about inserting a new attribute into a html tag and the code below does the job nicely, but how should it be coded to add multiple attributes, for example changing..
<body bgcolor="#DDDDDD">
to...
<body bgcolor="#DDDDDD" topmargin="0" leftmargin="0">
The code that works for a single attribute is...
document.getElementsByTagName("body")[0].setAttribute("id", "something");
How to modify this for inserting multiple attributes?

Reset to default 5As simple as calling it twice:
var body = document.getElementsByTagName("body")[0];
body.setAttribute("topmargin", "0");
body.setAttribute("leftmargin", "0");
Using jQuery:
$('body').attr({
topmargin: 0,
leftmargin: 0
});
Using JS:
Write a function yourself like:
HTMLElement.prototype.setAttributes= function(attrs, values) {
for(var i=0;i<attrs.length;i++){
this.setAttribute(attrs[i] ,+values[i]);
}
};
//And call it like:
document.getElementById('custom-header').setAttributes(['topmargin','leftmargin'],['0','0'])
May By like this
document.getElementsByTagName("body")[0].setAttribute("id", "something");
document.getElementsByTagName("body")[0].setAttribute("topmargin", "0");
document.getElementsByTagName("body")[0].setAttribute("leftmargin", "0");
