我不知道如何处理 $.post() 上的 404 错误?
$.post(url, data, function(returnedData) {
它只能处理成功数据,但我也想处理 404 错误。我知道如何用 ajax 来做,但不知道这个功能,请帮忙。
function returnData(url,data,type){
$.post(url, data, function(returnedData) {
if(type == "contacts")
{
ko.applyBindings(new ContactsViewModel(returnedData,"#KnockOutContacts",url,data),$("#KnockOutContacts")[0]);
ko.applyBindings(new ContactsViewModel(returnedData,"#ContactDetails",url,data),$("#ContactDetails")[0]);
}
else if(type == "logs")
{
alert(returnedData);
alert(1);
ko.applyBindings(new LogsViewModel(returnedData,url,data),$("#KnockOutLogs")[0]);
}
else if(type == "sms")
{
ko.applyBindings(new SmsViewModel(returnedData,"#KnockOutSmsData",url,data),$("#KnockOutSmsData")[0]);
ko.applyBindings(new SmsViewModel(returnedData,"#KnockOutSms",url,data),$("#KnockOutSms")[0]);
}
else if(type == "calendar")
{
ko.applyBindings(new CalendarViewModel(returnedData,"#KnockOutCalendar",url,data),$("#KnockOutCalendar")[0]);
}
else if(type == "search")
{
ko.applyBindings(new SearchViewModel(returnedData,"#searchbox",url,data),$("#searchbox")[0]);
}
else if(type == "location")
{
ko.applyBindings(new LocationViewModel(returnedData,"#KnockOutMaps",url,data),$("#KnockOutMaps")[0]);
}
else if(type == "photos")
{
ko.applyBindings(new PhotosViewModel(returnedData,"#photogallary",url,data),$("#photogallary")[0]);
ko.applyBindings(new PhotosViewModel(returnedData,"#PhotosDown",url,data),$("#PhotosDown")[0]);
}
});
}
我在获取数据时基本上应用绑定,但是当我没有获取数据时,它不会进入成功函数,这会破坏我的 js。
