我尝试使用以下方法添加它：
<input id = "date" type="text" value="DD/MM/YYYY" onfocus="this.value = this.value=='DD/MM/YYYY'?'':this.value;" onblur="this.value = this.value==''?'DD/MM /YYYY':this.value;">

Take a look at this fiddle: http://jsfiddle.net/tuliomonteazul/EGUcj/
看看这个小提琴：http: //jsfiddle.net/tuliomonteazul/EGUCj/
To fix the default value when the page loads I just commented the last call of checkVal();.
And to fix the onblur to apply the default value too, I commented the checkVal();inside the .bind('blur.mask')and changed the onblurfunction of the input.
为了在页面加载时修复默认值，我刚刚评论了checkVal();. 为了修复 onblur 以应用默认值，我在checkVal();里面 评论.bind('blur.mask')并更改onblur了输入的功能。
I think the plugin's license permits to change his code.
我认为插件的许可证允许更改他的代码。
