Microsoft sample code<%

The handler for each button's <code>click</code> event sets navigation history points using the <code>Sys.Application</code> object. The script used here, makes use of the <code>Sys.Debug</code> class to dump trace information to the TEXTAREA at the bottom of the page. </p> <p>When you click the buttons, and history points are added, you will be able to see the list of history entries and their titles in the "Recent Pages" drop-down in Internet Explorer, for example. </P> <p>To see history in action, perform the following steps:</p> <ol> <li>Press <b>1</b>. See the trace output.</li> <li>Press <b>3</b>. See the trace output.</li> <li>Press <b>2</b>. See the trace output.</li> <li>Press the browser's Back button. Notice that the page is refreshed with previous data and that trace information shows this.</li> </ol> <div id="div2" class="box">0</div><p></p> <input type="button" id="clientButton1" value="1" /> <input type="button" id="clientButton2" value="2" /> <input type="button" id="clientButton3" value="3" /> <br /><br /> <textarea id="TraceConsole" cols="40" rows="5"></textarea> </div> </form></body></html>扫码关注公众号，了解更多管理，见识，育儿等内容
