datagrid selected Multiple Rows delete bug for easy1.4.2 !!! [BUG]

[zhangjin]

To obtain the index is not correct. It is Unable to delete.
Code:   
var rf=$('#modelFieldGrid');
var rows=rf.datagrid('getSelections');
for(var j=0;j<rows.length;j++){
   var index = rf.datagrid('getRowIndex', rows[j]);
   rf.datagrid('deleteRow',index);
}

The 'getRowIndex' method returns the index of the special row in the current page. This method returns -1 if the row does not exists. Please check your code carefully to see if the row is exists.

   var index = rf.datagrid('getRowIndex', rows[j]);
   rf.datagrid('deleteRow',index);
}

I think after the code rf.datagrid('deleteRow',index) executed;,the 'rows' array will change.
