带有日期限制的蒙版输入插件 [英] Masked input Plugin with date limit
问题描述
我使用MM / YYYY格式的日期的输入文本字段上的蒙版输入。
( http://digitalbush.com/projects/masked-input-plugin/ )
我的JavaScript代码:
jQuery ($){
$(。date)。mask(12/2099);
});
和HTML代码:
< input type =textclass =date>
当我开始写字段时,值为12/2099,这是不可能写的其他的东西。
如果在javascript屏蔽我写99/9999,用户可以写日期是假的...所以我不是我要做的? / p>
我希望用户可以从01/1990开始直到2012年12月12日才能写入,可能会添加到+ 20年的价值的限制,或类似的东西...
嗯,我认为有掩码的输入是好的,但我更喜欢验证输入值,因为这些的插件通常与内部使用正则表达式。
我的解决方案可能是:

为邮件添加div
< form id =frm>
< input type =textclass =date>
< div id =msg>< / div>
< input type =submitvalue =点击我/>
< / form>
js:
< script type =text / javascript>
函数verifyDate(datevalue){
var done = false;
if(datevalue!= null || datevalue!=''){
//将日期分割为tmp var
var tmp = datevalue.split ('/');
//获取月份和年份
var month = tmp [0];
var year = tmp [1];
if(month> = 1&& month< = 12){
if(year> = 1990&& year< = 2099){
//清理消息
clean();
//最后,允许用户传递submit
done = true;
} else {
$('#msg')。html('Year must be from 1990 - 2099.');
}
} else {
$('#msg')。html('Month is invalid。');
}
}
return done;
}
function clean(){
$('#msg')。html('');
}
jQuery(function($){
//屏蔽输入
$(。date)mask(12 / 2099);
$('#frm')。submit(function(){
var datevalue = $('。date')val();
return verifyDate(datevalue)
});
$(。date)。keyup(function(){
//获取日期
var datevalue = $ (this).val();
//只有当日期是这样的时候:'xx / xxxx'continue
if(datevalue.length == 7){
verifyDate(datevalue);
} else {
clean();
}
});
});
< / script>
希望这有帮助。
I use masked input on a input text field for a date in the MM/YYYY format. ( http://digitalbush.com/projects/masked-input-plugin/ )
My javascript code:
jQuery(function($){
$(".date").mask("12/2099");
});
And HTML Code:
<input type="text" class="date">
When I start to write something it take to the field the value 12/2099 and it's impossible to write other thing.
If in javascript mask I write 99/9999, users could write date that is false ... so I don't what I have to do ?
I want to users that they could write starting on 01/1990 until 12/2099, possible adding to the restrict with the value of the date + 20 years or something like that ...
Well, I think is good to have the masked input but I prefer to validate the input value cause these kind of plugins generally works with regex from inside.
My solution for this could be:
(EDITED AND TESTED)
Adding a div for a message
<form id="frm">
<input type="text" class="date">
<div id="msg"></div>
<input type="submit" value="Click Me"/>
</form>
the js:
<script type="text/javascript">
function verifyDate(datevalue) {
var done = false;
if(datevalue != null || datevalue != ''){
//split the date as a tmp var
var tmp = datevalue.split('/');
//get the month and year
var month = tmp[0];
var year = tmp[1];
if(month >= 1 && month <= 12){
if(year >= 1990 && year <= 2099){
//clean the message
clean();
//finally, allow the user to pass the submit
done = true;
} else {
$('#msg').html('Year must be from 1990 - 2099.');
}
} else {
$('#msg').html('Month is invalid.');
}
}
return done;
}
function clean() {
$('#msg').html('');
}
jQuery(function($) {
//mask the input
$(".date").mask("12/2099");
$('#frm').submit(function() {
var datevalue = $('.date').val();
return verifyDate(datevalue)
});
$(".date").keyup(function(){
//get the date
var datevalue = $(this).val();
//only if the date is full like this: 'xx/xxxx' continue
if(datevalue.length == 7) {
verifyDate(datevalue);
} else {
clean();
}
});
});
</script>
Hope this helps.
