Script to limit max size of string field.

[Ian46]

Hi,

I have many string fields set to 400 characters. This allows the boxes to be the right size. However I need to stop users putting in too much data. How best to do this with a script?

I tried an On Change Client script, but it didn't work:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') 
   {
      return;
   }
   if(newValue.length>4000) 
   {
      g_form.showErrorBox("your_field","You cannot enter more than 4000 characters",true);
   }
}

Can anyone suggest the best way to achieve this?

Thanks Ian

Check this link, this is probably the solution you want. OOB and no code solution

Enable the text field character counter

Thanks that's good to know. Typically it doesn't work in SP though, so that isn't going to work for this case unfortunatley, as far as I can see.

Hi,

So the maximum length should be 4000.

Did you try to give alert in the client script

I tried but failed, I am using it in SP if that makes a difference?
