上例子
根目录下txt文件内容:apple banana pear
html代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function gettext() {
var xmlhttp;//定义
if (window.XMLHttpRequest) {
//创建XMLHttpRequest(IE7+、Firefox、Chrome、Safari、Opera)
xmlhttp = new XMLHttpRequest();
}
else {
//IE5 and IE6
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("showtext").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "/test.txt", true);//向服务器发送请求
xmlhttp.send();
}
</script>
</head>
<body>
<input id="btn1" type="button" value="get获取" onclick="gettext()" />
<div id="showtext"></div>
</body>
</html>
