How to solve the bug of innerHTML and getElementsByName in IE

For example, there is such a problem.
Copy codeThe Code is as follows:
<Div id = "playlist">
</Div>

Add a playlist to this div. This list is added with innerHTML.
Copy codeThe Code is as follows:
Var plst = null;
Plst = player. getPlaylist ();
If (plst ){
Var txt = '';
For (var I in plst ){
Txt + = '<a name = "fv_item_a _' + I + '"> </a> <div class = "fv_item" id = "fv_item _' + I + '"> <div class = "playing_bg" name = "playing_bg"> </div> ';
Txt + = '<div class = "playing" name = "playing"> playing... </div> ';
Txt + = ' ';
Txt + = '<p class = "fv_playlist_title">' + plst [I]. title + '</p> ';
Txt + = "</div> ";
}
Var obj = document. getElementById ("playlist ");
If (obj ){
Obj. innerHTML = txt;
}
}

You don't have to worry about complicated code in the middle. Now I want to retrieve the div whose name is playing. Easy to use
GetElementsByName
However, it is very strange that it cannot be obtained under ie. GetElementById is fully usable.
Below is a good solution:
Copy codeThe Code is as follows:
Function GetElementsByName (tag, name ){
Var elem = document. getElementsByTagName (tag );
Var arr = [];
Var index = 0;
Var l = elem. length;
For (var I = 0; I <l; I ++)
{
Var att = elem [I]. getAttribute ("name ");
If (att = name ){
Arr [index ++] = elem [I];
}
}
Return arr;
}

You can use this function. Only one more parameter is required.
I don't know if there are any other solutions for bloggers. This solution is not perfect. Leave a message in the comment.
