Hi All,

I have a field for frequency in catalog item to update it in Custom Table.

This field should be 234.234 format. how can i restrict it in Client Script. 

Below is my Client Script.

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

      return;

   }

   //Type appropriate comment here, and begin script below

   var reg = /^[0-9]*\.[0-9]\d{3}$/;

    var ans = g_form.getValue('frequency_number_u');

    if(!reg.test(ans))

    {

        alert('Please enter a valid value.');

        g_form.clearValue('frequency_number_u');

    }

}

Try this ...

// Regular expression to match the format "123.456"
var reg = /^\d+\.\d{3}$/;
var ans = g_form.getValue('frequency_number_u');

Hi @karthik65 ,

Use below script, i have tested it, working fine. it will accept 3 digit before and after decimal. If you before digit can be anything then use :var reg = /^\d+\.\d{3}$/;

var reg = /^\d{3}\.\d{3}$/;
    var ans = g_form.getValue('frequency_number_u');
   
    if(!reg.test(ans))
    {
        alert('Please enter a valid value.');
        g_form.clearValue('frequency_number_u');
    }

If you want exactly 3 degits on either side of the . (dot)
Then you need to reuse the d{3}
Like: 

/^\d{3}.\d{3}$/

@karthik65 ,

Please try by using below regex:

/^\d{3}\.\d{3}$/
