问题 I'm using jQuery 1.7.2 and would like to make a POST request to another domain. It must be a POST request. But this does not work in internet explorer (I tried on IE9); it works on all other browsers. I have this script: <script> jQuery.support.cors = true; jQuery(function() { $.ajax({ crossDomain : true, cache: false, type: 'POST', url: 'http://someotherdomain/test.php', data: {}, success: function(da) { console.log(JSON.stringify(da)) }, error: function(jqxhr) { console.log('fail') console

HTML中form表单get提交和Post提交的区别

﹥>﹥吖頭↗ 提交于 2020-01-13 17:04:15
在form表单中有一个属性method,也就是提交方法。如果你没有设定,那么默认的就是get方式提交,那么两种提交方式的区别有哪些呢? 1.get是从服务器上获取数据,post是向服务器传送数据。 2.get是把参数数据队列加到提交表单的ACTION属性所指的URL中,值和表单内各个字段一一对应,在URL中可以看到。post是通过HTTPpost机制,将表单内各个字段与其内容放置在HTML HEADER内一起传送到ACTION属性所指的URL地址。用户看不到这个过程。 3.对于get方式,服务器端用Request.QueryString获取变量的值,对于post方式,服务器端用Request.Form获取提交的数据。 4.get传送的数据量较小,不能大于2KB。post传送的数据量较大,一般被默认为不受限制。但理论上,IIS4中最大量为80KB,IIS5中为100KB。 5.get安全性非常低,post安全性较高。 6、get获取,post更新。 来源: CSDN 作者: Master.Yuan 链接: https://blog.csdn.net/yuanwen52/article/details/103957590

So are
