onerror

Description

Fires when a scripting error occurs (for example, when there are security problems during the loading process or when there is a problem in the code).

Remarks

When programming in VBScript, you can create an event handler that receives event parameters by defining a subroutine having this form:

Sub window_onerror(message, url, line)
    window.event.returnValue=true

The line parameter is an integer specifying the line number at which the error occurred, url is a string specifying the URL of the document containing the error, and the optional message is a message string. Returning true for the event prevents the default error message for Internet Explorer from displaying.

The following example uses JScript.

function errortrap(msg,url,line){
    alert(msg);
    return true;
}
onerror=errortrap;

This event will not bubble. Events that do not bubble can only be handled on the individual object that fired the event.

Applies To

window
