It takes 4 parameters: field(which is usually just set to "this"),maxlength(the max number of characters allowed in the field),id(the id of the textarea), and counter(the ID of the span or div that is around where your number is).įirst off, I check to see how many characters are in the textarea already. ![]() The next function is updateCounter(), and this one is a doozy. It will probably be 0, but if the user clicks the back button after they had already entered text into the textarea, then it will update the number right when the page loads. The number in that place is actually the max amount of characters you want in the textarea), and then subtract the value of the textarea so far. The function will set it to 350(which can be changed, I just used 350 in this case. This will check a division on the page with the ID "countArea", which is where you're variable number will be held. The first thing that I have done is whenever the window is loaded, a function with the name init is called. ![]() Well surprisingly, that isn't too much code to take in. Now, here we will examine some JavaScript.įield.value = (0, maxlength) ĭocument.getElementById(counter).innerHTML = However, you probably noticed how I have added some functions to the textarea depending on some actions you do (whenever you release a key or paste something). I have not put any text in it to begin with, just so we can keep the counter nice and simple. Below I have posted the simple HTML code you'll need: it's really just a textarea, no form needed for this simple script: Don't know what I'm talking about!? then check out the demo here. I'm just going to go over a basic one here, and you can probably figure out the rest. I got this idea from, where their news submission page has this implemented. so yea, I've some some nice content to share! Here, I want to discuss how to make a part of text that will update a number according to how many characters you type into the textfield, and once you reach the limit you will not be able to type anymore. I've been awfully busy with stuff, and such. Hey guys, It's been a while since my last post. ![]()
