Determine whether the browser is an ie browser. Use this line of code if (window.ActiveXObject || "ActiveXObject" in window) to determine the browser type. If it is an IE browser, it returns true, otherwise it returns false. In the case, an alert pop-up box will pop up to show whether it is an IE browser.

<script></p> <p>function test(){</p> <p>　if (window.ActiveXObject || "ActiveXObject" in window){</p> <p>　　alert(" ie")</p> <p>　}else{</p> <p>　　alert("not ie")</p> <p>　}</p> <p>}</p> <p></script>
