how to set maxlength for textarea in javascript

I know that HTML has a maxlength attribute, but I want to limit the number of words typed not characters.

After 10 words the user should be able to move his cursor left & edit the text, but not add any more words.

So how can I stop the cursor?

Any suggestions?

Only javascript please.

HTML textarea maxlength Attribute, Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java  Thanks, this works for me, but need to add unique id for every label of word count when used on multiple textarea element e.g. cntid=obj.attr('id')+"-counter_label", this will get the id of each textarea and use to define id of the counter label.

(The question isn't totally clear... I'm assuming it means "how do I prevent the user from typing more than ten words in a textarea?")

I think you'll struggle to achieve this. What about Paste, for instance?

Here's an alternative suggestion, which might be appropriate for what you're doing: one way that modern UIs (eg. Twitter) deal with this is to put up a letter count or a word count, which turns red once you've gone past the limit. You then get an error if you try to submit the form. That's much easier to achieve than trying to prevent the user from typing more than ten words in the first place.

Textarea - Limit Word Count with jQuery, Just a simple tool to limits the amount of words in a textarea by disabling all keys when the word limit is matched, but still allows the backspace and $("textarea").characterCounter(200); A brief explanation of what is going on.. On every keyup event the function is checking what type of key is pressed. If it is acceptable the the counter will check the count, trim any excess and prevent any further input once the limit is reached. The plugin should handle pasting into the target too.

HTML5 validation is made for tasks like these:

  onkeypress="if(!this.validity.valid){this.value=this.value.slice(0,-1);return false;}"/>

if it's to be submitted, you can omit the onkeypress handler, as the form won't submit if something's invalid.

One can use poly-fills to support older browsers with this syntax.

How to limit the number of characters entered in a textarea in an , To add a multi-line text input, use the HTML tag. You can set the size of a text area using the cols and rows attributes. To limit the number of  < textarea rows = " 4 " cols = " 50 " maxlength = " 50 " placeholder = " Enter text here " > </ textarea > The maxlength attribute specifies a fixed number of characters that a textarea can take. The user can still choose to enter fewer characters than the maximum limit, but he/she cannot enter more.

Like @sgroves this answer is just for fun :)


  $('textarea').on('keydown', function(e){
    // ignore backspaces
    if(e.keyCode == 8)

    var that = $(this);
    // we only need to check total words on spacebar (i.e the end of a word)
    if(e.keyCode == 32){
      setTimeout(function(){ // timeout so we get textarea value on keydown
        var string = that.val();
        // remove multiple spaces and trailing space
        string = string.replace(/ +(?= )| $/g,'');
        var words = string.split(' ');
        if(words.length == 10){
          that.val(words.join(' '));
      }, 1);

set a 250 word limit in a textarea, Well, you can't set a limit by words but, you can by characters through the <p>​This JavaScript sets a maximum word count to a textarea. The maxlength attribute specifies the maximum length (in characters) of a text area.

Encountered a similar issue recently... here is my take

  • @akonsu you can understand that? O_O
  • @kakonosze you mean do u want to focus out?
  • I want just stop currsor and i must use javascript :) What u mean focus out?
  • @karkonosze what do u mean by stopping cursor? you want to stop user from inputting more data?
  • yes, but user can back cursor! If u think about atribut disable or readonly this is not good for me.
  • u are realy fast! Now i must immplement this on my Fckeditor :)
  • what if i typed " this is a test "? (edit to see extra spaces)
  • like i said, this solution is not perfect (easy to fix that with a regex though -- just trim all multiple spaces down to one space before splitting the string). like i also said, i don't actually recommend using this solution. it was just for fun.
  • yes u have right! I think I saw something like that on difrent pages.
  • for the record, i definitely think this is the better approach. my answer is mostly just for fun.
  • what if i wanted to type pokémon?
  • @sgroves: we can use \S instead of \w if we define words as able to have non-wordy+non-space chars like "-" or "é" within.
  • Oops just saw that its not a new line he wants but to only allow 10 words period. Will edit.
