JS Post mode new open window

JS in general new open window very simple direct window.open (URL);

But because I want to pass parameters to the server, and the parameters look a long string, and the Get method has a limited length of commit parameters, I have the following requirements:

Implementing post Submissions in 1,js

2, the returned page is displayed in a new window

First of all, I did this:

$.ajax ({                        "POST",                        ' ${contextpath}/analyse/detail.do ',                        data: {carnum:carnum,ids : Refids},                        function(str_response) {                           var obj = window.open ("About:blank" );                           Obj.document.write (Str_response);                        }                    

By jquery Ajax submission, the returned data is written in a new page, but because the browser will intercept the automatic pop-up window, which also requires users to unblock themselves, the user experience is poor,

Then I do this by simulating the submission of form forms.

functionPost (URL, PARAMS) {varTemp_form = document.createelement ("form"); Temp_form. Action=URL; Temp_form. Target= "_blank"; Temp_form. Method= "POST"; Temp_form. Style.display= "None";  for(varXinchPARAMS) {                      varopt = document.createelement ("textarea"); Opt.name=x; Opt.value=Params[x];                  Temp_form. appendchild (opt);                  } document.body.appendChild (temp);             Temp_form. Submit (); }      

Note: If you want the target property of the new open window form to be set to ' _blank '

Then request post (' ${contextpath}/analyse/detail.do ', {carnum:carnum,ids:refids});
