Topic awaiting preservation: Releasing the maxLength limit

How do I reset the maxLength of a text field? i've tried setting to null, but that makes the field uneditable. ideas?

<input type="text" id="time" value="0" size="3" maxlength="2">

document.getElementById("time").value=0
document.getElementById("time").maxLength=1
document.getElementById("time").size=2

You should set maxLength to greater to zero if you want to edit it. It determines how many characters can be typed into a field.

Is that what you are asking for?

Or did you want to eliminate the length restriction altogether?

If that's the case, you might try setting it to Number.POSITIVE_INFINITY... actually, I'm not sure if you're allowed to use that property of the Number object, but try Number.MAX_VALUE (the highest possible number allowed in JavaScript). If that doesn't work either, just use 99999 or something.

I ended up just alerting the default value (which is 2147483647) and assigning it to a global definition:

var INPUT = {maxLength: 2147483647};



document.elements[n].maxLength = INPUT.maxLength;

using Number.MAX_VALUE and Number.POSITIVE_INFINITY causes the field to be uneditable also.

Just out of curiosity, what kind of input are you expecting to get into those fields? The max integer is larger than most input I can imagine. I guess it's best to be safe though, so you're doing the right thing.

Interesting. 2^31 - 1. Almost makes sense, but it's as if it's allowing negative numbers... oh, I know why. Cool. I believe that's the highest number allowed in JavaScript.
