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();
