PRB: The Window.open File Within HREF Returns [OBJECT] in Current Window

View products that this article applies to.

Symptoms

The browser window's page disappears and is replaced by the word "[object]" when you use the following code to open a new window from an HREF:

<a href="javascript:window.open('http://www.microsoft.com');">Click here</a>

↑ Back to the top

Cause

This problem occurs because the browser is navigating to the window object returned by the Window.open file call.

This behavior is by design.

Resolution

To resolve this problem, perform one of the following:
  • Add a void (0), as illustrated here, to give a no return value: 
    <a href="javascript:window.open('http://www.microsoft.com'); void(0)">Click here</a>
    -or-

  • Call your own JScript function to open a new window. This prevents the hyperlink navigation and allows you to retain a reference to the opened window. 
    <SCRIPT>

var childWin;

function OpenUrl(url) {
	childWin = window.open(url);
}

</SCRIPT>

<a href="javascript:OpenUrl('http://www.microsoft.com');">Click here</a><p>
