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("(999) 999-9999");
$("#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
Next, call the mask function for those items you wish to have masked.

$("#phone").mask("(999) 999-9999");
$("#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

$("#product").mask("99/99/9999",{placeholder:" "});
});

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('~',"[+-]");
$("#eyescript").mask("~9.99 ~9.99 999");
});
jQuery(function($){
$("#product").mask("99/99/9999",{completed:function(){alert("You typed the following: "+this.val());}});
});
You can now supply your own placeholder character definitions.
jQuery(function($){
$.mask.addPlaceholder('~',"[+-]");
$("#eyescript").mask("~9.99 ~9.99 999");
});
