How to make a single line text variable in service catalog to accept only numerical values

[andrewdevadhas]

Hi SNOW users,

I have a Service catalog form with a single line text variable. I need to make it to accept only numerical values. 

Is there any similar validation properties available for any of the variables in service catalog

HI Andrew

There is no numeric type available for variables. Yo can write a client script to enforce numeric value to the required field.Check below script

var var_name= g_form.getValue('VARIABLE_NAME');
var a = var_name.match(/^[0-9]+$/);
if(a == null){
g_form.clearValue('VARIABLE_NAME');
g_form.showFieldMsg('VARIABLE_NAME','this field should be numeric value only','error');

}

HI Andrew,

Have a look.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var number = g_form.getIntValue('u_quantity');
//if "Not a Number", clear the number value
if (isNaN(number)){
//number = "";
g_form.setValue('u_quantity','');
g_form.showFieldMsg('u_quantity','Please enter a valid integer number - stripping out non-numeric characters','info');

}

}

Hi Raju,

But this validation will hapen only after the order is submitted right? we can't do any validations prior that?

Andrew,

This client script is on Onchange condition. when ever variable value is changed- script will trigger to work.
