Jquery掩码插件

在最近项目中需要用到一些输入过滤，很自然的就想到需要使用掩码来进行操作，因为这样会尽量使程序变得简单。查找了Jquery，发现一款插件能够解决这个问题，插件地址为：http://space.cz2000.cn/batch.viewlink.php?itemid=3940

在此摘录一段原文，有助于理解其用法：

First, include the masked input javascript file.

Next, call the mask function for those items you wish to have masked.

jQuery(function($){
$("#date").mask("99/99/9999");
$("#phone").mask("[phone]");
$("#tin").mask("99-9999999");
$("#ssn").mask("999-99-9999");
});
Optionally, if you are not satisfied with the underscore ('_') character as a placeholder, you may pass an 

optional argument to the maskedinput method.

jQuery(function($){
$("#product").mask("99/99/9999",{placeholder:" "});
});
Optionally, if you would like to execute a function once the mask has been completed, you can specify that 

function as an optional argument to the maskedinput method.

jQuery(function($){
$("#product").mask("99/99/9999",{completed:function(){alert("You typed the following: "+this.val());}});
});
You can now supply your own placeholder character definitions.

jQuery(function($){
$.mask.addPlaceholder('~',"[+-]");
$("#eyescript").mask("~9.99 ~9.99 999");
});
