Jquery object help


 
jQuery.fn.checkBoxTableHighlighter = function(){
 return this.each(function() {  
  var $obj = $(this);
  var jsObj = this; 
 [COLOR=red][B] var $table = $("tr > td", this);[/B][/COLOR]
[B][COLOR=red] alert($table.attr("tag")); //coming up as undefined[/COLOR][/B] 
  if(jsObj.tagName.toLowerCase() == "input" && jsObj.type.toLowerCase() == "checkbox"){
   //actions on check box
  }
  else if(jsObj.tagName.toLowerCase() == "table"){
   //actions on table
 
   //on page load, highlight rows for a table that has a specified selector
      $obj.children().filter(':has(:checkbox:checked)').closest("tr").addClass(defaults.highlightClass);
      //on page load, remove high light for the check boxes that are not checked
      $obj.children().filter(':has(:checkbox:not:checked)').closest("tr").removeClass(defaults.highlightClass);
      //check box clicked with the specified table css selector
      $obj.children().filter(':has(:checkbox)').click(function (e) { 
       highlight.CheckBoxRowSelect(e, $(this));
      });
      //check box keyup with the specified table css selector
      $obj.children().filter(':has(:checkbox)').keyup(function (e) {
          highlight.CheckBoxRowSelect(e, $(this));
      });
  }
 
 
 
 
 });
};

call:


$(".someItem").checkBoxTableHighlighter();

When the check box is checked (onload, click or keyup), if the table has a specified selector then i want to change the background color. I already have a working sample that i am converting to plugin. Since, my selector is at the table level, how can i find the checkboxes that are inside tr and td?

I have changed to following and still no luck:

I have simplified it:

Call:


$(".tableHighlightSelector tr td input[type='checkbox']").checkBoxTableHighlighter();

Code:


return this.each(function() {  
  var $obj = $(this);
  var jsObj = this; 
  $obj.closest("tr").addClass("rowhighlight");
 
 });

closest tr is now coming up as undefined.

I am using jquery 1.6.1.

fixed, here is the full plugin:

call:


//when the check box is checked then the row will get highlighted. If it  gets unchecked then the row highlighting will be removed
$("input[name='somename']").checkBoxTableHighlighter();
//to uncheck the check boxes and clear highlighting
$("input[name='somename']").checkBoxTableHighlighter('clear');

plugin:


jQuery.fn.checkBoxTableHighlighter = function(method){
    var defaults = {  
        highlightClass: "rowhighlight"
    };  
    var methods = {
        init: function(options){

                $.extend( defaults, options );
