jquery校验问题
为什么校验不好使
代码如下
//初始化校验
$("#deptAddForm").validationEngine({
validationEventTrigger:'',
  promptPosition:"centerRight" 
});
//提交按钮
$("#submitBtn").click(function(){
var ss=$('#deptAddForm').validationEngine('validate');
//alert('ss='+ss);
//alert($('#parentId').val());
$.post(
"<%=basePath%>/back/privilege/deptLayout!update",{
rand: encryption(),
parentId:$('#parentId').val(),
name:$.trim($("#name").val()),
shortName:$.trim($("#shortName").val()),
seq:$('#seq').val(),
status:$('#status').val(),
flag:$('#flag').val(),
id:$('#id').val()
},function(json){
if(json.success){
alert('操作成功!');
var DG = frameElement.api;
DG.opener. refreshList();
}else{
alert(json.msg);
}
},'json'
);
});
//重置
$('#clearBtn').click(function() {
$('#deptAddForm')[0].reset() ;
$('#deptAddForm').validationEngine('hide');
});

});

//html 代码
