1.获取项目路径的,不一定有用,仅作参考用:
function getRootPath() {
var curWwwPath = window.document.location.href; //"http://localhost:8080/springMVC/jsonTest.jsp"
var pathName = window.document.location.pathname; // /springMVC/jsonTest.jsp
var pos = curWwwPath.indexOf(pathName); //
var localhostPath = curWwwPath.substring(0, pos); //http://localhost:8080
var projectName = pathName.substring(0, pathName.substr(1).indexOf('/') + 1); // /springMVC return (localhostPath + projectName); //http://localhost:8080/springMVC
}
2.马士兵shopping项目中动态修改table单元格:
单元格html:
js代码:
说明:
changeToInput:
根据id找到span;
拿到span的value值;
outerHTML <------> innerHTML outerHTML 将整个的html全部替换掉了;
显示在input输入框中;获得焦点;
onblur时候触发change(id)方法,根据id去修改;
修改响应成功之后,再变回span;

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>开始计时和停止计时的小东西</title>
<link rel="stylesheet" type="text/css" href="bootstrap/bootstrap.min.css">
<style type="text/css">
.demo {
padding: 10px;
margin: 100px 0 0 100px;
}
</style>
</head>
<body>
<div class="demo">
<input type="button" value="开始计时" onClick="timedCount()">
<input type="text" id="txt">
<input type="button" value="停止计时" onClick="stopCount()">
</div>
</body>
<script src="jquery/jquery.min.js"></script>
<script src="bootstrap/bootstrap.min.js"></script>
<script type="text/javascript">
var c=0;
var t;
function timedCount(){
document.getElementById("txt").value=c;
c=c+1;
t=setTimeout("timedCount()",1000);
}
function stopCount(){
c=0;
setTimeout("document.getElementById('txt').value=0",0);
clearTimeout(t);
}
</script>
</html>
