jquery class selector doesn't work in IE6 -

eidt: , sorry carelessness. inittree() fails.

this works fine in ff , chrome:

$("#tree").treeview({     collapse:false, }); 

this works fine in ff chrome , ie6:

$("#tree").treeview({     collapse:false  //<-here key, no comma }); 

i have tree like:

<ul id="tree">     <li>root         <ul>             <li>node_1_2<a class='addnode'>add</a><a class='deletenode'>delete</a>                 <ul>                     <li>node_2_4<a class='addnode'>add</a><a class='deletenode'>delete</a></li>                     <li>node_2_6</li>                 </ul>             </li>         </ul>     </li> </ul> 

if click <a>add</a>, should append chid node element. like:

$("a.addnode").live("click", function() {     if($(this).parent().children("ul").html() == null){         leafhtml = ...;         $(this).parent().append(leafhtml);     }     else{         leafhtml = ...;         $(this).parent().children("ul").append(leafhtml);     }     inittree(); }); 

this works fine in firefox , chrome. in ie6 did nothing. seem $("a.addnode") didn't work.

first of need way debug happening. there things firebug lite can check out suggest placing couple of alerts.

$("a.addnode").live("click", function() {     alert('click caught');     if($(this).parent().children("ul").html() == null){         alert('no children');         leafhtml = ...;         $(this).parent().append(leafhtml);     }     else{         alert('children');         leafhtml = ...;         $(this).parent().children("ul").append(leafhtml);     }     alert('end');     inittree(); }); 

you know get's called , doesn't called instead of guessing. if should take guess there 2 errors here cause problem. selector fine.

1: $(this).parent().children("ul").html() == null never true. should check against $(this).parent().children("ul").children().length == 0 instead.

2: $(this).parent().children("ul").append(leafhtml) makes no sense. text inside ul not valid , wouldn't suprised if ie6 ignores it(it should).

i suspect #1 makes #2 happend , invalid ie6 ignores it.
