子窗口关闭按钮

Question

This is my code. When I click the close button on the child window it will display suresh on the screen but if I call popuponclick() function at the time itself suresh is getting displayed. What I do??

 popuponclick = function() { window.ChildWindow = window.open('GOLF12/shared/launchpage.html', 'popupWindow', 'width=700,height=700'); window.ChildWindow.attachEvent("onunload", OnChildWindowClose()); } OnChildWindowClose = function() { document.getElementById("my").innerHTML = "suresh"; window.ChildWindow = null; };

This will likely work better on your server

It does not run if there is a popup blocker, then you will need to test if ChildWindow was opened correctly

this fiddle works , but stacksnippets fail on the popup blocking

var ChildWindow;
function  popuponclick() {
  ChildWindow = window.open('GOLF12/shared/launchpage.html',
    'popupWindow',
    'width=700,height=700');
  setTimeout(function() { // we need to have the new page active
    ChildWindow.addEventListener("unload",OnChildWindowClose)
  },100)
}
function OnChildWindowClose() {
  this.opener.document.getElementById("my").innerHTML = "suresh";
  this.opener.ChildWindow = null;
};

<button onclick="popuponclick()">Click</button>
<span id="my"></span>
