kndo grid：通过checkbox 实现多选和全选

在kendo grid 里要想通过checkbox 实现多选和权限，我们就要通过templeate 和input 标签对kendo grid 进行自定义

1. 在column 里面加入一列checkbox

{ title: " <input id='checkAll' type='checkbox' id='chkSelectAll' onclick='selectAllRow(this)' /> ", template: "<input type='checkbox' onclick='selectRow()' class='grid_checkbox' />", width: 60, filterable: false, sortable: false },

然后实现全选方法

function selectAllRow(ele) {
   var state = $(ele).is(':checked');
    if(state)
    {
        //selectRow();
        $('tr').find('[type=checkbox]').prop('checked', true);
        $('tr').removeClass("k-state-selected");
        $('tr').addClass("k-state-selected");
    }
    else
    {
         $('tr').find('[type=checkbox]').prop('checked', false);
          $('tr').removeClass("k-state-selected");
    }
