如何使用 JQuery 输入掩码设置表单输入的最小长度？

Question

I'm using RobinHerbots' input mask to set my UUID input. It all works, but I want to retain the HTML message when the input does not have x numbers of characters and the submit button is clicked. HTML alert

I don't like clearIncomplete: true because it deletes partial inputs.

My submit button triggers an event and sends a request to the server using fetch.

Here's my current code:

   $(document).ready(function(){
        $('.id').inputmask({
            mask: "*{8}-*{4}-*{4}-*{4}-*{12}",
            definitions: {'*': {validator: "[0-9a-f]"}},
            casing: "lower",
            removeMaskOnSubmit: true,
            // clearIncomplete: true
        });
    });

HTML:

<form action="" id="form">
    <p><input type="text" name="id" id="id" class="id" size="50" required /> * 32 characters</p>
    <input type="reset" value="reset" onclick="resetForm()">
    <input type="submit" value="divert" />
</form>

EDIT: I can't figure out how to do it. I settled with using another simpler plugin and keeping minlength/maxlength in the input tag. Igor Escobar's JQuery Mask Plugin .

Answer 1

have you thought about using the onincomplete, you could make a function to show a div, or tooltip or an alert. NoTe, this is just a quick and dirty example:

 let isvalid = false; $("#tooltip").hide(); $('#id').inputmask({ mask: "*{8}-*{4}-*{4}-*{4}-*{12}", definitions: { '*': { validator: "^[0-9a-f]" } }, casing: "lower", onincomplete: function() { isvalid = false }, oncomplete: function() { isvalid = true } }); $("#form").submit(function(e) { if (!isvalid) { $("#tooltip").show(); let tooltip = setInterval(function() { clearInterval(tooltip); $("#tooltip").hide(); }, 3000); e.preventDefault(); return } $("form").submit(); });

 #tooltip{ display: none; position: absolute; cursor: pointer; left: 100px; top: 50px; border: solid 1px #eee; background-color: #ffffdd; padding: 10px; z-index: 1000; }

It seems the input mask doesn't play well with the jquery UI tooltip when using minlength, I hope this helps

Actually now that i think about it there is an easier way

 $(document).ready(function() { $('.id').inputmask({ mask: "*{8}-*{4}-*{4}-*{4}-*{12}", definitions: { '*': { validator: "[0-9a-f]" } }, casing: "lower", removeMaskOnSubmit: true, // clearIncomplete: true }); }); $(document).ready(function() { $("#form").validate({ rules: { 'id': { required: true, minlength: 32 }, } }); });
