javascript length 函数

javascript中length是只中文的个数+其他字符的个数。

测试浏览器为chrome

测试代码如下:

<html>
<head>
<script language="javascript" type="text/javascript">
function cal_length() {
var swv =  document.getElementById('myinput').value;
alert('input length is:' +swv.length);
}
</script>
</head>
<body>
	<form id="a" method="post">
	<input type="text" id="myinput" name="myinput" /> <br/>
	<input type="button" value="Calculate Length" id="myok" name="myok" onclick="cal_length()"/>
	</form>
</body>
</html>

java里面时间类型转换成json数据就成这样啦
"createTime":{"date":30,"day":3,"hours":15,"minutes":14,"month":3,"nanos":0,"seconds"
:38,"time":1209539678000,"timezoneOffset":-480,"year":108}
在gridpanel里面就会显示成[object,object]

解决办法,使用里面的time构造Date,然后输出Date。

myDate = new Date(row[fieldname].time);
detail += myDate.getFullYear()+ '-' + (myDate.getMonth() + 1)
	  + '-' + myDate.getDate() + ' ' + (myDate.getHours() + 1)
	  + ':' + myDate.getMinutes() + ':' + myDate.getSeconds();
