1.布局
<h2>ajax</h2> <button type="button" onclick="LoadText()">请求数据</button> <div id="mydiv"></div>
2.js函数
<script type="text/javascript"> function LoadText() { var xmlhttp; if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState==4 && xmlhttp.status==200){ document.getElementById("mydiv").innerHTML = xmlhttp.responseText; } } xmlhttp.open("GET","/ajax/HtmlPage1.html",true); xmlhttp.send(); } </script>
3.前提是路径下有"/ajax/HtmlPage1.html",这个html
4.全部html
<!DOCTYPE html> <html > <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <script type="text/javascript"> function LoadText() { var xmlhttp; if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState==4 && xmlhttp.status==200){ document.getElementById("mydiv").innerHTML = xmlhttp.responseText; } } xmlhttp.open("GET",true); xmlhttp.send(); } </script> </head> <body> <h2>ajax</h2> <button type="button" onclick="LoadText()">请求数据</button> <div id="mydiv"></div> </body> </html>
