SP 2013 - Limit a ML TextBox entry to 250 words

Hi Guys

 

I am new to using Javascript with Nintex for SP2013 and I was wondering if someone could help me out with this. Lets say I have a multi line textbox called 'projsumm' and I want to restrict the number of words to be put into this entry to 250 words. I had found this code on a previous thread and was wondering if i could use it in some way although I am unsure as to how to reference the actual textbox 'projsumm' in this particular case.

 

function wordCount(source, args) {

var words = args.Value.split(” “);
words = NWF$.grep(words, function (element, index) {
if (element.trim() != “”) {
return true;
}
});
if (words.length < 20)
{
args.IsValid = false;
}
}

 

Any help would be greatly appreciated or providing alternative methods of how to achieve what I am after.

 

Cheers,

    Hi @AussieBattler10,

    for a text-only multiline textbox I got this working:

     

    NWF$("#" + multibox).val().split(" ").length

     

    this assumes that there will not be any double/tripple spaces.

    For use with multiple spaces, this might work:

     

    NWF$("#" + multibox).val().split(" ").reduce(function (sum, current) { return sum += current.trim() != ""; }, 0);

     

    EDIT: Or this if you do not want to use reduce

    NWF$("#" + multibox).val().split(" ").filter(function (elt) { return elt.trim() != ""; }).length;

    Hi @Tarf 

     

    Thanks for that. I still have a few questions.

     

    - in your code at which point am I referring to my JS variable 'projsumm'. I assume its 'Multibox'

    - also at which point am I defining the word limit amount of 250? I don't see any mention of a number in your code to define this point.

     

    Thanks again for your help

     

    Cheers,

    Hi @AussieBattler10,

    sorry I was totally missing on the validation part.

    Go to the custom js section of your form and paste this code (change the variables to match yours):

    function validateMulti(){ var len = NWF$("#" + multibox).val().split(" ").filter(function (elt) { return elt.trim() != ""; }).length; console.log(len) return len > 250; }

    Add a validation rule to the multi-line text.
    Control is invalid if... -> validateMulti()

    And thats it.

    I have a console.log in the validation function to see if it is called. You can of course remove this.
