ajax提交，总是进入error,我在后台打断点，都没进action就进了error,打印XMLHttpRequest.status为200，XMLHttpRequest.readyState为4，textStatus为parseRerror,什么原因，求大神解答。
function constructOrder(){
var mobile = $("#mobile").val();
var authCode = $("#inputCaptcha").val();
var count = $("#num").val();
if(isNan()){
$.ajax({
url : "pcElectromobile_constructOrder.action",
type : "post",
dataType : "json",
data : {"mobile":mobile,"authCode":authCode,"count":count},
success : function(data) {
if(data.status == 'y'){
JM.alert("请求中。。。", 2000, JM.goUrl(data.info));
}else{
JM.alert(data.info, 2000);
}
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
alert(textStatus);
}
});
}
}
在Validform中调用：
function isvalid(){
var $payForm = $("#payForm");
$payForm.Validform({
btnSubmit : "#go_pay",
tiptype:function(msg, o, cssctl) {
if(!o.obj.is("form")) {
var objtip = o.obj.siblings(".Validform_checktip");
cssctl(objtip, o.type);
objtip.text(msg);
} else {
var objtip = o.obj.find("#msgdemo");
cssctl(objtip, o.type);
objtip.text(msg);
}
},
ajaxPost:true,
beforeSubmit : function(curform) {
constructOrder();
return false;
}
});
}
