ajax请求不用刷新页面,比form提交要好不少,ajax的插件也很多,最近百度了一下ajax源码,源码很简单,但他却很实用,代码如下:
<!Doctype html>
<html>
<head>
<meta
charset='utf-8'>
<script>
function
load() {
var
xmlhttp;
if (window.XMLHttpRequest) {
xhmhttp =
new XMLHttpRequest()
}
else {
xmlhttp =
new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET",
"/try/ajax/ajax_info.txt",
true);
xmlhttp.send();
xmlhttp.onreadystatechange =
function() {
if (xmlhttp.readyState ==
4 && xmlhttp.status ==
200) {
document.getElementById("myDiv").innerHTML
= xmlhttp.responseText;
}
}
}
</script>
</head>
<body>
<button
type="button"
onclick="loadXMLDoc()">修改内容</button>
</body>
</html>
关键词:XMLHttpRequest,new
ActiveXObject("Microsoft.XMLHTTP"),open,send,onreadystatechange
这段代码确实可行,不喜勿喷,交流讨论添加微信号:17312678391
