javascript - How to get the value of custom HTML attribute using JQuery? -

-

i have repeater check boxes in each row. i'm trying check check box in row based on check box in same row. i'm executing function on onclick event of check box , function finds custom attribute of parent , checks if parent checked or not. if returned true checks check box same attribute name child class . th problem can't value of custom attribute of parent class. undefined.

childid in jquery function undefined. tried using data property it's of no use . 

$(objid).data('chldname'); function check_view(objid) {     var childid = $(objid).attr('chldname');     if ($(objid).is(':checked')) {         $("[name=" + childid + "]").attr('checked', true);     } }

html:

<td style="text-align: center">     <asp:checkbox id="cb_uploadaccess" runat="server" chldname='chld<%#eval("role_seq")%>' onclick='javascript:return check_view(this);' />     <asp:hiddenfield id="hiddenuploadaccess" runat="server" value='<%#eval("upload_access")%>' />  </td> <td style="text-align: center">     <asp:checkbox id="cb_viewaccess" name='chld<%#eval("role_seq")%>' runat="server" />     <asp:hiddenfield id="hiddenviewaccess" runat="server" value='<%#eval("view_access")%>' />  </td>

create data-chldname attribute , access using 

$(objid).attr('data-chldname')
