threshold as dynamic and not fixed number?

[DePalmo]

Per the documentation, we can set a fixed number for threshold which works great, but I do have cases where threshold is required as low as 1 character and some other cases where 5 (or 10, 20, etc.) would be more appropriate. Since I'm using a single init for all input fields that have maxlength attribute, that enhancement would be superb, otherwise I would need to have multiple init calls with different threshold set.

Is this something that could be considered in next update?

Old comment, but another vote for this, it'd be really useful to scale the threshold value depending on the maxlength value - perhaps to set it as a percentage.

I also needed this functionality. While this may not be the best solution, it does work and gives the desired result. It allows you to have a single init call for all input fields and dynamically determine the appropriate threshold value. One issue with this approach is that I had to explicitly set alwaysShow to false.

[...document.querySelectorAll('[maxlength]')].map(el => {
    var maxLength = el.getAttribute('maxlength');
    var threshold = maxLength - Math.round(maxLength * 0.75);

    $(el).maxlength({
        alwaysShow: false,
        threshold: threshold
    });
})

You can adjust the percentage value in the Math.round call to change the value. For example, if the maxlength is 255, the threshold will be 64 characters.
