Sys.Debug trace Method

Appends a text line to the debugger console and to the TraceConsole<textarea> element, if available.

Syntax

Sys.Debug.trace(text);

Arguments

text

The text to display.

Remarks

Debugging behavior, requirements, and the output of trace messages vary with different browsers. For more information, see ASP.NET AJAX Debugging and Tracing Overview

Example

The following example shows a click handler function that writes a line to the trace console. The example assumes the existence of an HTML element named Text1 in the default <form> element of the page. This is part of a larger example from the Sys.Debug class overview.

CS

function btnTrace_onclick() {
    v = form1.text1.value;
    Sys.Debug.trace("Name set to " + "\"" + v + "\".");
    alert("Hello " + v + ".");
}

VB

function btnTrace_onclick() {
    v = form1.text1.value;
    Sys.Debug.trace("Name set to " + "\"" + v + "\".");
    alert("Hello " + v + ".");
}
