如何用POST替换window.open（...） [英] How to replace window.open(...) with a POST

问题描述

我目前有一些运行 window.open（urlWithGetParams）行的代码。据我所知，这将迫使我使用 GET 请求。我想用POST请求来做到这一点。有没有解决这个问题的方法？

我还没有和 window.open（）结婚。我对任何允许我通过POST请求而不是GET产生新窗口的替代方法都是开放的。

>实际上，我为此创建了一个小型库，在POST中打开一个新窗口：

  //参数：
 //动词：'GET'|'POST'
 // target：可选打开目标（名称或_blank），默认为_self
 open = function ，url，data，target）{
 var form = document.createElement（form）; 
 form.action = url; 
 form.method = verb; 
 form.target = target || _自; 
 if（data）{
 for（var key in data）{
 var input = document.createElement（textarea）; 
 input.name = key; 
 input.value = typeof data [key] ===object？ JSON.stringify（data [key]）：data [key]; 
 form.appendChild（input）; 
} 
} 
 form.style.display ='none'; 
 document.body.appendChild（form）; 
 form.submit（）; 
}; b 
 
 
 
 $ b示例： code> open（'POST'，'fileServer.jsp'，{request：{key：42，cols：[2，3，34]}}）; 
  

要在新窗口中打开，请设置目标参数：

  open（'POST'，someURL，someArgs，'newwin'）; 
  

或确保每次都是新的窗口/标签：

  open（'POST'，someURL，someArgs，'_blank'）; 
  

很明显，您应该给它一个不同于打开，这样你就不会影响现有的。理想情况下，您应该命名空间。

I currently have some code that runs a window.open(urlWithGetParams) line. As far as I'm aware, this is going to force me to use a GET request. I would like to do this with a POST request. Is there a workaround for this?

I'm not married to window.open(), either. I'm open to just about any alternative that allows me to spawn a new window via a POST request instead of a GET.

解决方案

In fact I made a small "library" just for this, open in POST a new window :

// Arguments :
//  verb : 'GET'|'POST'
//  target : an optional opening target (a name, or "_blank"), defaults to "_self"
open = function(verb, url, data, target) {
  var form = document.createElement("form");
  form.action = url;
  form.method = verb;
  form.target = target || "_self";
  if (data) {
    for (var key in data) {
      var input = document.createElement("textarea");
      input.name = key;
      input.value = typeof data[key] === "object" ? JSON.stringify(data[key]) : data[key];
      form.appendChild(input);
    }
  }
  form.style.display = 'none';
  document.body.appendChild(form);
  form.submit();
};

Example :

open('POST', 'fileServer.jsp', {request: {key:"42", cols:[2, 3, 34]}});

To open in a new window, set the target parameter :

open('POST', someURL, someArgs, 'newwin');

or to ensure it's a new window/tab each time :

open('POST', someURL, someArgs, '_blank');

Obviously you should give it a name other than open so that you don't shadow the existing one. Ideally you should namespace it.
