Question

i want to add an attribute to a table header without id or class. all it has is field. my code here does not work. i appreciate any help

$(th[field = "item_group_ID"]).attr('hidden', 'true');

or is there any other way i can do this? heres the table

<table id="dg" title="jaiko pogi " class="easyui-datagrid" style="width:980px;height:370px;"
        url="show_biochem.php"
        toolbar="#toolbar" pagination="true"
        rownumbers="false" fitColumns="true" singleSelect="true" height="auto";>
    <thead>
        <tr>
        <th field="item_group_ID" width="8">ID</th>
        </tr>
    </thead>

$('#dg').datagrid('hideColumn','item_group_ID');

Your selector is incorrect. It should be a string:

$('th[field="item_group_ID"]').attr('hidden', 'true');

Also, are you trying to hide the element? If so, adding an attribute called "hidden" won't do it.. try this instead:

$('th[field="item_group_ID"]').hide();

You are missing the quotes:

$("th[field='item_group_ID']").attr('hidden', 'true');

If you are trying to hide the selected element use .hide() function, instead.

What are you trying yo do? If you want to hide the element, just use `.hide()` jQuery function. – Ionică Bizău Aug 19 '13 at 18:13
tried it, still wouldnt hide. http://www.jeasyui.com/demo/main/index.php this is the one im using. – raymond Aug 19 '13 at 18:21

If you want to use an attribute that is not part of the official HTML syntax (i.e. field), you can use attributes named data-* (i.e. data-field). So:

<th data-field="item_group_ID" width="8">ID</th>
