checkbox多选框选择判断

全选<input type="checkbox" name="select" id="select" value="checkbox" onclick="selectAllCheckBox(this);" />

<input type='checkbox' name='id' value='"+list[i].id+"'/>

var arr = $("input[type='checkbox'][name='id']:checked");
var ids = "";
$.each(arr,function(index,o){
    ids = ids + $(o).val()+",";
});
ids = ids.substring(0,ids.length-1);

function selectAllCheckBox(o){
  var arr = $("input[name='id']");
  $.each(arr, function(index, current) {
      current.checked = o.checked;
  });
}
