XMLHttpRequest POST并在新窗口/选项卡中打开目标页面 [英] XMLHttpRequest POST and open target page in new window/tab

问题描述

如何在 target =_ blank来模拟Form的'POST' >的XMLHttpRequest ？ （即发布数据，并在新标签中打开目标页面）

解决方案

gBrowser
$ b

  var dataStream = Cc [@ mozilla .ORG / IO /串输入流; 1\" ]的createInstance（Ci.nsIStringInputStream）; 
 dataStream.data =foo = bar& alpha = beta; //确保值正确编码encodeURIComponent 
 
 var postStream = Cc [@ mozilla.org/network/mime-input-stream;1\"].createInstance(Ci.nsIMIMEInputStream）; 
 postStream.addHeader（Content-Type，application / x-www-form-urlencoded）; 
 postStream.addContentLength = true; 
 postStream.setData（dataStream）; 
 
 gBrowser.loadOneTab（http://www.example.com/，{inBackground：false，postData：postStream}）; 
  




How do you emulate Form's 'POST' action with target="_blank" in XMLHttpRequest? (ie post data and open target page in a new tab)

解决方案

gBrowser offers this functionality right out of the box.

var dataStream = Cc["@mozilla.org/io/string-input-stream;1"].createInstance(Ci.nsIStringInputStream);
dataStream.data = "foo=bar&alpha=beta"; // make sure the values are properly encoded with encodeURIComponent

var postStream = Cc["@mozilla.org/network/mime-input-stream;1"].createInstance(Ci.nsIMIMEInputStream);
postStream.addHeader("Content-Type", "application/x-www-form-urlencoded");
postStream.addContentLength = true;
postStream.setData(dataStream);

gBrowser.loadOneTab("http://www.example.com/", {inBackground: false, postData: postStream});
