A perfect solution to the problem of return value compatibility in JS modal window _javascript tips

Because the system should be compatible with the original IE has been used to close the method, measured by debugging, it is necessary to window.dialogarguments more than the test, otherwise easy to problem.

function Okend (vals) {
  if (Vals = null) Vals = "TRUE";
  if (typeof (Window.opener) = = "undefined") {
    if (typeof (Window.dialogarguments)!= "undefined") {
      if (window.dia logarguments && window.dialogarguments!= null) {
        window.opener = window.dialogarguments;
        if (window.opener && window.opener!= null) {
          window.opener.ReturnValue = vals;
        }
      }
    }
  }
  else {
    if (window.opener && window.opener!= null) {
      window.opener.ReturnValue = Vals;
    }
  }
  Window.returnvalue = Vals;
  Self.close ();
}

Return value received, only in the original IE received mode, more than a Test opener on it, as follows:

Select Change Department
     function SetOrganizeTree2 () {var url= "pop-up page";
       var ret = window.showmodaldialog (URL, window, "Dialogwidth=400px;dialogheight=500px;status=no;help=no;scroll=yes"; Resizable=yes; ");
       if (typeof (ret) = = "undefined") {
         ret = window. returnvalue;
       }
       if (ret) {
         document.getElementById ("HidDeptCode2"). Value = RET;
         document.getElementById ("Btndeptcodeadd"). Click ();
       return false;
     }

JS modal window return value compatibility problem perfect solution

1. When the pop-up window is opened, the window is passed as the second parameter.

 var result = window.showModalDialog (URL, window, "dialogwidth=" + width + "px;dialogheight=" + height + "Px;resizable:yes; ")

 if (typeof (Result) = = ' undefined ') {result

     = window. returnvalue;

   }

   return result;

2, in the pop-up window, execute the following JS to receive the incoming window

 if (typeof (Window.opener) = = ' undefined ') Window.opener = window.dialogarguments;

3, the pop-up window before closing, call the following JS assignment return value

 Window.returevalue = Vals;

    if (window.opener && window.opener!= null)

        window.opener.ReturnValue = Vals;

 

    Window.close ();

Principle discussion:

Chrome, the standard method, when the pop-up page does not postback, can return a value. A postback is not a normal return value. This method can be resolved.

IE standard method, sometimes unknown reason can not return the value correctly, this method can be resolved.

FF not tested in detail, should not be a problem.
