client script to check string length and restrict user

[sry]

Hi all,

                    we have a requirement to restrict user not to enter more than 100 characters for a field of type string. currently the field length is 120 but we don't want user to enter more than 100. For this i am thinking a "onChange" client script, i am not sure onChange is correct. Could you please guys help me how to write a clientscript to restrict the user by displaying an error beside the field to correct the length of the message he typed to 100 based on condition of assignedto=ABC,assignment group=XYZ.

Thanks,

Sry

Hi Sry,

Sample script-Untested code. Adjust as per your req.

var assignedto = g_form.getDisplayBox('assigned_to').value;
var assignmengrp = g_form.getDisplayBox('assignment_group').value;
var field = g_form.getValue('short_description').length;
if(assignedto == 'XXX' && assignmengrp == 'XXX' && field>100)
   {
   alert('YOUR TEXT');
   return false;
}

Hi Sry,

If it is a field of type string the dictionary form has a field called Max Length where you can enter the number of characters. This is obviously different to the width of the field which could be larger.

If it is a variable of Single line text you can add a attribute called max_length

If either of the above doesnt fit your requirement, there is a blog post below which details a client script aiding in achieving the same.
