easyui--validate验证

$('#email').validatebox({
required:true,
validType:'minLength[5]',
delay:3000,
missingMessage:'请填写电子邮件',
invalidMessage:'请填写正确的电子邮件',
deltaY:120,
novalidate:true,

});
$('#email').validatebox('destroy');
console.log($('#email').validatebox('validate'));
console.log($('#email').validatebox('isValid'));

以及自定义验证：

$.extend($.fn.validatebox.defaults.rules,{
minLength:{
validator:function(value,param){
return value.length>=param[0];
},
message:'请长度不小于{0}的字符',
},
});
