IE6/7 GetAttribute Get href/src Property (relative path 0 value differs from other browsers _javascript tips

The test code is as follows:

Home <script> var link = document.getelementsbytagname (' a ') [0]; var img = document.getelementsbytagname (' img ') [0]; Alert (Link.getattribute (' href ')); Alert (Img.getattribute (' src ')) </script>
[Ctrl + A All SELECT Note: If the need to introduce external JS need to refresh to perform]

There are elements A and IMG (standard document mode), and a relative path is set. The browser effects are as follows

IE6/7: Return to full path

Ie8/9/10/firefox/safari/chrome/opera: Returns a relative path

If you want to be consistent with other browsers in Ie6/7, you can set the second argument for GetAttribute to 2.

Home <script> var link = document.getelementsbytagname (' a ') [0]; var img = document.getelementsbytagname (' img ') [0]; Alert (Link.getattribute (' href ', 2)); Note the second parameter alert (img.getattribute (' src ', 2)); Note the second parameter </script>
[Ctrl + A All SELECT Note: If the need to introduce external JS need to refresh to perform]

The standard getattribute method is not to define the second parameter, the magic ie AH. The following is an MSDN description of the setattribute parameter
