未捕获的TypeError：无法读取未定义的属性“位置”

Question

• I am new to js,

  • I am getting an error at the line popup.location.href = "/desktop/main"; as Uncaught TypeError: Cannot read property 'location' of undefined,
  • how to fix the problem

  • providing my code below

      success: function () { // me.showNewWindowSuccess(menu, newWindowId); me.registerMenuClick(menu, newWindowId); popup.location.href = ""; }, scope: me }); }, 

Answer 1

You are not passing the url to the function openNewWindow

the if(url) returns false in the function, so it never returns anything.

thats the reason for popup to be undefined
