首先要明白什么是 AJAX ？ AJAX = 异步 JavaScript 和 XML。 AJAX 是一种用于创建快速动态网页的技术。 通过在后台与服务器进行少量数据交换，AJAX 可以使网页实现异步更新。这意味着可以在不重新加载整个网页的情况下，对网页的某部分进行更新。 传统的网页（不使用 AJAX）如果需要更新内容，必需重载整个网页面。 有很多使用 AJAX 的应用程序案例：新浪微博、Google 地图、开心网等等。 1、AJAX - 创建 XMLHttpRequest 对象 XMLHttpRequest 对象 所有现代浏览器都支持 XMLHttpRequest 对象 （IE5 和IE6 使用AcActiveXObject）。 XMLHttpRequest 用于在后台与服务器交换数据。这意味着可以在不重新加载整个网页的情况下，对网页的某部分进行更新。 所有现代浏览器（IE7+、Firefox、Chrome、Safari 以及 Opera）均内建 XMLHttpRequest 对象。 创建 XMLHttpRequest 对象的语法： variable = new XMLHttpRequest(); 老版本的 Internet Explorer （IE5 和 IE6）使用 ActiveX 对象： variable=new ActiveXObject( "Microsoft

In CORS, Are POST request with credentials pre-flighted ?

由 半世苍凉 提交于 2019-12-13 15:24:09
问题 In MDN Access Cotrol doc, GET request with credentials are not preflighted. But if response headers doesn't include Access-Control-Allow-Credentials: true then response will not be available to the invoking client. If this behaviour same for POST (Simple POST request with credentials - Content Type may be form-data) request as well, there is risk that POST might change the server state though response may not be made available to client. Is this assumption correct? OR POST request with

How to download large file with JavaScript

由 孤人 提交于 2019-12-13 13:16:30
问题 I need to download a large file with JavaScript using XMLHttpRequest or fetch without saving the file first in the RAM-Memory. Normal link download doesn't work for me, because I need to send a Bearer Token in the header of the request. I could manage to download a file, but this "solution", it's saving the file first in the RAM-Memory, before I get a save dialog, so that the Browser will brake if the file is larger then the available RAM-Memory. Here is my "solution" with fetch: var
