您正在使用jquery来处理登录功能，但不会阻止默认执行。

这部分

$("#submit_login").click(function(){   
      username=$("#username").val();
      password=$("#password").val();

应包含

$("#submit_login").click(function(event){
      event.preventDefault();
      username=$("#username").val();
      password=$("#password").val();

为了阻止浏览器发布您的表单。

您可以在jQuery documentation

中详细了解相关信息
