Question

Suppose on my HTML page I have many hrefs to a link.

Using Javascript, I need to loop through all hrefs and replace them with something and I don’t have any ids to a href.

Please help.

Answer 1

var anchors = document.anchors;
for(var i=0,len=anchors.length;i<len;i++){
   anchors[i].href = 'some_new_url';;
}

Edit (after OP’s comment)

document.anchors return anchors collection provide anchors have name attribute in them.

These are valid anchors for document.anchors

   <a href='http://www.link1.html' name=''>Link1</a>
   <a href='link2.html' name=''>Link2</a>

But this is not,

<a href='link2.html'>Link2</a>

Better, use this instead

var anchors = document.getElementsByTagName('a');
for(var i=0,len=anchors.length;i<len;i++){
    anchors[i].href = 'some_new_url';;
}
