Internet Explorer does not recognize window.opener.location as valid, while there are no issues with Chrome

 Response.Write("<script language='javascript'>alert(window.opener.location.pathname); if(window.opener.location.pathname.toString() == \"/page.aspx\"){window.opener.document.forms[0].submit();}</script>");

While this code works in Chrome, I encountered a JavaScript runtime error in Internet Explorer indicating that 'location' is null. It appears to be related to the use of 'opener'.

Is there an equivalent solution for this issue in IE?

Answer №1

Avoid using Response.Write to insert JavaScript into your web page. When you check the page source, you'll notice that the script is injected before any HTML content on the page, which is not ideal.

Instead, consider utilizing RegisterStartUpScript.

ClientScriptManager cs = Page.ClientScript;
Type cstype = this.GetType();
String cstext1 = "alert(window.opener.location.pathname);";
cs.RegisterStartupScript(cstype, "alert", cstext1, true);

Answer №2

Experiment with window.opener.document.location:

Response.Write("<script language='javascript'>alert(window.opener.document.location.pathname); if(window.opener.document.location.pathname.toString() == \"/page.aspx\"){window.opener.document.forms[0].submit();}</script>");
