$(function() {

//自定义评语内容验证方法
jQuery.validator.addMethod("levelLimit",function(value, element){
var returnVal = false;
var level = $("#code").attr("level");
if(level=="1" || level=="0"){
returnVal = true;
}
return returnVal;
},"level不能为2!");
$("#appEdit_Form").validate({
rules : {
"code" : {
required : true,

levelLimit : true//期望的是true,如果为false则展示提示信息
}
},
messages : {
"code" : {required : "请输入务编码！",
number : "请输入数字！"
}
},
errorPlacement: function( lable, element ){
element.ligerHideTip();
element.parent().ligerTip({ content: lable.html(), target: element[0] });
},
success : function( lable ){
lable.ligerHideTip();
lable.remove();
},
submitHandler: function(formTar){
var serialStr = $("#appEdit_Form").serialize();
var urlStr = './appIndex.htm?actionMethod=addAppInfo';
$.ajax({
type:'post',
url:urlStr,
data:serialStr,
success:function(redata){
if (redata ==1) {
alert( '操作成功!');
}else{
alert('失败提示', '操作失败!');
return;
}
}
});
}
});
});
