character limit on single line field

[sarahkapasi]

We have a Service Catalog Item with a single line field variable which has character limit to 40 characters.

I would like to make it so the user can't 'Order Now' until 40 characters are in that field.

Thank you,

Sarah

Check on Onchange script for that field.

var textBox = g_form.getValue("field_name").length;  

if(textBox <40)  

{  

  alert("Please enter full field");  

}

Ty this:

function onSubmit() {

  var text = g_form.getValue("u_epic_device_haiku_canto");

  var length=text.length;

if(length <40)

{

  alert("Please enter full field");

  return false;

}}

Thanks so much!   That worked!

I have a similar challenge but in this case it should only be possible to enter six numbers from 0 to 9. How shold the if-sentence look like in order to achieve that?

Best regards

Doesn't work.  This field never saves.

Very lame that this happens.  It's absurd that you can't set max_length, and that you'd need to rely on an onSubmit script to handle it.

So, I personally get the maxlength attribute set by manipulating the DOM via an SP widget:

I have a Single Line Text field named "upc" as a Catalog Item Variable.
