js uses post method to open a new window_javascript skills

Generally, opening a new window in js is very simple, just window.open(url); and that’s it,

But because I want to pass parameters to the server, and the parameters seem to be a long string, and the length of parameters submitted in the get method is limited, so I have the following requirements:

1. Implement post submission in js

2. The returned page will be displayed in a new window

First I did this:

Copy code The code is as follows:

$.ajax({
Type: "POST",
                     url: '${contextPath}/analyse/detail.do', 
                          data: {carNum:carNum,ids:refIds}, 
Success: function(str_response) { var obj = window.open("about:blank");
                                                                                                                                                                                                                                                                                                               });

Submitted through jQuery ajax, the returned data is written in a new page, but because the browser will intercept the automatic pop-up window, the user needs to unblock it himself, and the user experience is very poor,

Then I implemented it by simulating form submission

Copy code The code is as follows:

function post(URL, PARAMS) { var temp_form = document.createElement("form");                 temp_form .action = URL;                                                temp_form .target = "_blank";

              temp_form .method = "post";                                                   temp_form .style.display = "none"; for (var x in PARAMS) {                                                                                                                              opt.name = x;                                                                        opt.value = PARAMS[x];                                                                       temp_form .appendChild(opt);                                                                                                                                                  document.body.appendChild(temp);                                                                                                          temp_form .submit();                                                                   }



Note: If you want to open a new window, the target attribute of the form must be set to '_blank'

Then request post('${contextPath}/analyse/detail.do',{carNum:carNum,ids:refIds}); and that’s it
