从json,我得到的值是
"createdOn": "Jan 08 2015 20:40:56 GMT+0530 (IST)",
我在FTL中访问
<#list variables as variable>
<div class="reply">
${variable.createdOn}
</div>
</#list>
我得到的结果是
Jan 09 2015 12:36:18 GMT+0530 (IST)
我的格式是
09-01-2015
我需要删除剩余的时间GMT,IST等。
如何在Freemarker模板或javascript中进行转换。
更新
我试图像这样传递下面的
${variable.createdOn?datetime?string("dd-MM-yyyy")}
但它正在给出错误
Exception: java.text.ParseException - Unparseable date: "Jan 09 2015 12:36:18 GMT+0530 (IST)"
任何帮助都是赞赏的。

首先,这是什么格式?我的意思是,如果你可以影响某人使用标准格式(主要是ISO),这将有助于每个人。无论如何,FreeMarker不是一个日期解析器库,但实际上你可以这样做:
<#-- Settings you need -->
<#setting date_format="dd-MM-yyyy">
<#setting locale="en_US">
<#-- The string that comes from somewhere: -->
<#assign createdOn = 'Jan 08 2015 20:40:56 GMT+0530 (IST)'>
<#--
1. Tell FreeMarker to convert string to real date-time value
2. Convert date-time value to date-only value
3. Let FreeMarker format it according the date_format setting
-->
${createdOn?datetime("MMM dd yyyy HH:mm:ss 'GMT'Z")?date}

你试过这个吗?
"${variable.createdOn?datetime?string('dd-MM-yyyy')}"

function convertDate( date ){
dateSplit = date.toString().split( ' ' );
dateSplit[1] = date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1).toString() : date.getMonth() + 1;
return dateSplit[2] + '-' + dateSplit[1] + '-' + dateSplit[3];
}
convertDate(new Date());
这应该可以胜任。你可以另外调整它

您可以创建自己的自定义功能,并使用getDate
,getMonth
和getFullYear
方法设置日期格式。
请注意,您必须将字符串日期格式解析为Date对象。
<!DOCTYPE html>
<html>
<body>
<p>Click the button to display todays day of the month in dd-MM-yyyy format.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var d = new Date("Jan 08 2015 20:40:56 GMT+0530 (IST)"); //parsing your string date format into Date object.
var z = d.getDate() + "-" + (d.getMonth() + 1) + "-" + d.getFullYear();
document.getElementById("demo").innerHTML = z;
}
</script>
</body>
</html>
