在extjs中更改日期格式

Question

我是extjs的新手，想要更改日期格式。

我正在从数据库中获取日期。我的日期格式为 - > YYYY-m-d，

并希望将此格式更改为d-m-YYYY。

。

Answer 1

这里有Date和Ext.Date.format类。 （版本4.1）

var dt = new Date('2012-05-31') 
'formatted Date:' + Ext.Date.format(dt,'d-m-Y') // 31-05-2012 

Answer 2

如果您正在使用Ext.data.Model你应该看看Ext.data.Field#dateFormat 正确地将接收到的数据。

使用网格，您可以查看列的渲染器Ext.grid.column.Column#renderer 并使用Ext.util.Format#dateRenderer作为渲染器。

Answer 3

如果您在模板中正在使用以下命令：

{MyDate:date("M")}

使用以下link找到所有的ExtJS的格式为ExtJs6.2
