在JQuery中调用Web服务并将返回的Json分配给JS变量

问题描述

这是我第一次尝试使用JQuery，Json并调用Web服务.

我需要使用JQuery调用webserivce，然后返回一个Json对象，然后将其保存到javascript变量中.我试图写一些东西.我只需要一个人来确认这确实是您的操作方式.在实例化它之前，可能会弄乱我公司服务器上的某些东西.无论如何，这里是:

var returnedJson = $.ajax({
    type: 'Get',
    url: 'http://172.16.2.45:8080/Auth/login?n=dean&p=hello'
});

就这样，用JQuery调用Web服务并将返回的jsonObject分配给javascript变量.谁能确认这是正确的?

提前谢谢！

解决方案

var returnedJson = $.ajax({
    type: 'Get',
    url: 'http://172.16.2.45:8080/Auth/login?n=dean&p=hello'
});

如果您这样做，则returnedJson将是XHR对象，而不是您之后的json.您想在成功回调中处理它.像这样:

$.ajax({
    // GET is the default type, no need to specify it
    url: 'http://172.16.2.45:8080/Auth/login',
    data: { n: 'dean', p: 'hello' },
    success: function(data) {
         //data is the object that youre after, handle it here
    }
});

This is my first time attempting working with JQuery, Json AND calling a web service.. So please bear with me here.

I need to call a webserivce using JQuery, that then returns a Json object that I then want to save to a javascript variable. I've attempted writing a little something. I just need someone to confirm that this is indeed how you do it. Before I instantiate it and potentially mess up something on my company's servers. Anyways, here it is:

var returnedJson = $.ajax({
    type: 'Get',
    url: 'http://172.16.2.45:8080/Auth/login?n=dean&p=hello'
});

So there it is, calling a webservice with JQuery and assigning the returned jsonObject to a javascript variable. Can anyone confirm this is correct?

Thanks in advance!

解决方案

var returnedJson = $.ajax({
    type: 'Get',
    url: 'http://172.16.2.45:8080/Auth/login?n=dean&p=hello'
});

If you do it like this returnedJson would be an XHR object, and not the json that youre after. You want to handle it in the success callback. Something like this:

$.ajax({
    // GET is the default type, no need to specify it
    url: 'http://172.16.2.45:8080/Auth/login',
    data: { n: 'dean', p: 'hello' },
    success: function(data) {
         //data is the object that youre after, handle it here
    }
});
