how to append string to

Question

I've the elements as follows, ``` ``` and I want it to be changed as follows within browser. ``` ``` So that I can use the "a" data values to next page. Can any one give me the code, which does the appends inside `div id="pager"` -> `` -> `href="` and i wants to remove the added text with another onChange event. Thanks in advance

Accepted Answer

Since jquery is tagged :

```
$('#pager a').each(function(){
     this.href += '?a=text';
})
```

Vanilla JS would look like this :

```
var a = document.getElementById('pager').getElementsByTagName('a'),
    length = a.length;

for(var i=0; i< length; i++){
    a[i].href += '?a=text';
}
```
