问题 I'm looking for a way to use JavaScript to store debug messages that appear in the Chrome console when xmlhttprequests are performed. Example output provided below: Thanks in advance! 回答1: You cannot read console messages from JavaScript. You will not be able to read these messages. However, using the same general concept as John Culviner's answer to Add a “hook” to all AJAX requests on a page, you can detect the events in JavaScript that cause these messages to appear.

     今天说点有意思的，之前jquery没有在提到，不过会发一个jquery文档让大家学习的，里面就有关于今天的主角Ajax的方法使用了，比原生的Ajax好用的多。大家用过Ajax吗？就比如说买东西的购物车数量的加减？不过没关系，今天就带大家认识一下Ajax。 1.那么什么是AJAX?   AJAX即“ A synchronous J avascript A nd X ML”（异步JavaScript和XML），是指一种创建交互式网页应用的网页开发技术。   AJAX的实际意义是，不发生页面跳转、异步请求载入内容并改写局部页面内容的技术。   AJAX也可以简单的理解为通过JS向服务器发送请求。   AJAX这门技术很早就被发明，但是直到2005年被谷歌的大量使用，才在市场中流行起来，可以说Google为AJAX的推广起到到推波助澜的作用。 同步处理与异步处理: 同步处理：   AJAX出现之前，我们访问互联网时一般都是同步请求，也就是当我们通过一个页面向服务器发送一个请求时，在服务器响应结束之前，我们的整个页面是不能操作的，也就是直观上来看他是卡主不动的。这就带来了非常糟糕的用户体验。首先，同步请求时，用户只能等待服务器的响应，而不能做任何操作。其次，如果请求时间过长可能会给用户一个卡死的感觉。最后

问题 I am trying to consume the weather web service provided by wsf.cdyne.com/WeatherWS/Weather.asmx. I am sure that I can get a response in XML format by using the uri " 'http://wsf.cdyne.com/WeatherWS/Weather.asmx/GetCityForecastByZIP?ZIP=' + zipcode".

Can I do a JSONP request with POST?

由 余生颓废 提交于 2020-01-16 07:18:07
问题 I'm trying to avoid jQuery and would like to use a native solution. How can I POST with JSONP? 回答1: You can't. JSONP works via inserting a <script> tag in the page, which then allows data to be retrieved from the remote server. Obviously there's no way to POST a <script> tag. 来源： https://stackoverflow.com/questions/9811478/can-i-do-a-jsonp-request-with-post

Is there any way, other than to use eval/handleAs: “javascript” to dynamically fetch scripts (via XMLHttpRequest)

问题 Here I have asked a question pertaining to exceptions raised when dynamically loading scripts via XMLHttpRequest (in other words when executed via eval ) In a related question, I wanted to know whether loading scripts dynamically as such is considered bad practice to begin with. In my particular case I have an HTML Canvas element, and rather than load all possible shapes, I want to fetch them dynamically, without reloading the page, and execute them on return. The problem I am having there is
