getjson

I have a loop that makes calls to an API and compiles the results into an array. How do I wait until all of the calls are finished until resuming execution? I see a bunch of answers for how to wait until one call is done, but I don't understand how to check for all of them. If I make a while loop that waits until 'obj' is the correct length, the page just stalls until the calls are done, which is not what I want. Help please? function getData(id) { var thisI = i; var url = "www.whatever.com?id=" + id; $.getJSON(url, function(data) { obj[thisI]=data; }); } obj = []; for (i=0; i < ids.length; i+

The code is very simple, I do not know why it deosnt work. This is the link to the JSON file, http://webapp.armadealo.com/home.json Here is the code using getJSON $.getJSON("http://webapp.armadealo.com/home.json", function(data){ alert(data); }); I just want the code to display the whole JSON content. After so many months of search, I found the solution. Hence, I am answering my own question. When JSON is not supported and when we are stuck with Same Origin Policy, we have to wrap around our JSON with a padding and make it a JSONP. To do that, we have a life saving website http://anyorigin.com

一、什么是跨域？ 因为javascript同源策略的限制，a.com 域名下的js脚本无法操作b.com或是c.a.com域名下的对象。 1.什么引起了ajax不能跨域请求的问题？ ajax本身实际上是通过XMLHttpRequest对象来进行数据的交互，而浏览器出于安全考虑，不允许js代码进行跨域操作，所以会警告。 网上有很多解决办法，下面介绍使用JQuery的getJSON方法 用getjson的回调，获取JSON数据 <script type="text/javascript"> $.getJSON("http://localhost:3856/GetItemCates.ashx/GetItemCats?gateid=20&format=json&jsoncallback=?", function (data) { var myprops = data.itemcats_get_response.item_cats.item_cat; $.each(myprops, function (index, item) { $("ul").append("<li>" + item.name + "," + item.cid + "</li>") }); } ); </script> 这是我在本地建立的一个测试项目，不同的端口，协议，都算不同的域。

前言： 为尽可能保证浏览器端安全，浏览器会遵循SOP协议，即同源协议 ajax无法完成跨域请求 $.get $.post $.ajax都不可以 jsonp作为ajax的一种扩展协议可以完成跨域请求 $.getJson()也可以完成跨域请求(当然不跨域也可以) 日常开发中会经常遇到前端跨域访问请求数据的场景 比如 www.server.com img.server.com 当用户在www下浏览 时需要获取指定记录id的图片，则我们需要在www的域下请求img域下的数据，常规情况下浏览器会处于安全控制限制无法完成跨域请求，但页面中的script或iframe标签是可以载入跨域请求的(link img也可以) 实现方式： =============================================================== 服务端 看网上很多讲跨域的都只是说了下前端如何编码，对后端的处理只字未提，虽然后端的处理很简单，但后端的处理才是点睛之笔，返回一个前端的调用函数语句，这就是传说中的回调函数 <?php if (isset($_GET['callback'])) { $callback = $_GET['callback']; $resultArr = []; $resultArr['id'] = $_GET['id']; $resultArr['img'] =

Google offers a wonderful REST interface for geocoding and reverse geocoding an address. My API key is valid, and if I enter the request directly into the browser address it works great. However, the following jquery fails terrible and I'm failing to see why. Hoping you could help me out here. $.getJSON("http://maps.google.com/maps/geo?q="+ address+"&key="+apiKey+"&sensor=false&output=json", function(data, textStatus){ console.log(data); }); Google's REST interface doc for this service: http://code.google.com/apis/maps/documentation/geocoding/index.html The problem here is that I wasn't

I have the following where I'm trying to send list/array to MVC controller method: var id = []; var inStock = []; $table.find('tbody>tr').each(function() { id.push($(this).find('.id').text()); inStock.push($(this).find('.stocked').attr('checked')); }); var params = {}; params.ids = id; params.stocked = inStock; $.getJSON('MyApp/UpdateStockList', params, function() { alert('finished'); }); in my contoller: public JsonResult UpdateStockList(int[] ids, bool[] stocked) { } both paramaters are null. Note that if I change the params to single items params.ids = 1; params.stocked = true; public

My problem is very simple, I have a file with the name of new.json and I am trying to use JQuery to load and display the data. I have been writing JavaScript code: $.getJSON("new.json", function(data){ // I have placed alert here previously and realized it doesn't go into here $.each(data.streetCity, function(i,s){ alert(s); }); }); } and the data in new.json looks as below: {"streetCity": { "1":"Abergement-Clemenciat", "2":"Abergement-de-Varey", "3":"Amareins" } }; If you are using Chrome. Because Chrome don't allow xmlhttprequest to request local file. So jquery can not load your new.json

When making a call out to the yahoo web service (http://boss.yahooapis.com/ysearch) to return a data set, is it possible to set a timeout and exit the routine once its elapsed? jQuery.getJSON("http://boss.yahooapis.com/ysearch/...etc", function (data) { //result set here }); You can use the timeout option http://api.jquery.com/jQuery.ajax/ $.ajax({ url: url, dataType: 'json', data: data, success: callback, timeout: 3000 //3 second timeout }); $.ajax({ url: url, dataType: 'json', data: data, success: callback, timeout: 3000 //3 second timeout, error: function(jqXHR, status, errorThrown){ //the
