如何基于jquery-ajax响应在同一窗口中打开新页面

Question

This might be easy but I'm having trouble doing this right. How can I open a new page in the same window using jquery-ajax response?

As you can see I'm trying to display a custom text if the php response is equal to the word "invalid". If not open a new html page in the same window.

   $("#lBtn").click(function(){
      $.post("php/session.php",
        { username:$("#username").val(), 
          password:$("#password").val()
        },
        function(response) {
          alert(response)
          if(response == "invalid"){
             $("#loginResponse").text("Error!!");
          } else {
             window.location = $(this).find('new/pahe.html').html();
            }
        });
    });

Alert(response) shows the word "invalid" but the if statement does not work. Means neither it display Error!! in $("#loginResponse") nor it opens the new page. That's what I want to fix.

You are probably getting additional white-space returned in the output from the post (maybe a carriage return or space?).

Trim the response:

function(response) {
    response = $.trim(response);
    if(response == "invalid"){

or just do this to check for a sub-string match:

function(response) {
    if(response.indexOf("invalid")>=0){
