js中哈希表的几种用法总结
1.
复制代码 代码如下:
<html>
<head>
<script type="text/javascript">
// by Go_Rush() from https://www..net/
var hash={
"百度" :"http://www.baidu.com/",
"Google" :"http://www.google.com/",
"微软" :"http://www.microsoft.com/",
"" :"https://www..net/"
};
function showUrl(element){ //使用哈稀对象
alert(hash[element.value])
}
</script>
</head>
<body>
<form>
<input type="text" id="txt" />
<input type="button" value="测试" onclick="showUrl(document.getElementById('txt'));"/>
</form>
</body>
</html>
2.
复制代码 代码如下:
<script>
var ht =
{
"c1" : {"UserID":"userc1","UserName":"usercc1"},
"c2" : {"UserID":"userc2","UserName":"usercc2"},
"c3" : {"UserID":"userc3","UserName":"usercc3"}
};
alert(ht["c1"]["UserID"]);
alert(ht["c2"]["UserID"]);
</script>

<script>
var Arr =new Array({'s':'sss','aa':'www'},{'s1':'wwww','aa1':'ssss'});
