如何将正文中的数字替换为波斯数字?

I want to convert every number in the html content to Persian numerals without other effects on page elements.

For example:

<div style='color: #c2c2c2'>
  text number 1
  <span>text number 2</span>
  <div>
    text number 3
    <b>text number 4</b>
    <a href='#page2'>text number 5</a>
  </div>
</div>

be converted to:

<div style='color: #c2c2c2'>
  text number ۱
  <span>text number ۲</span>
  <div>
    text number ۳
    <b>text number ۴</b>
    <a href='#page2'>text number ۵</a>
  </div>
</div>

let persian = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');
let english = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');

Thanks.

You can use this method: (http://jsfiddle.net/A4NfG/1/)

persian={0:'۰',1:'۱',2:'۲',3:'۳',4:'۴',5:'۵',6:'۶',7:'۷',8:'۸',9:'۹'};
function traverse(el){
    if(el.nodeType==3){
        var list=el.data.match(/[0-9]/g);
        if(list!=null && list.length!=0){
            for(var i=0;i<list.length;i++)
                el.data=el.data.replace(list[i],persian[list[i]]);
        }
    }
    for(var i=0;i<el.childNodes.length;i++){
        traverse(el.childNodes[i]);
    }
}
