Validate alpha numeric on a field in catalog item

SD29 · ‎03-03-2017

Hi Folks,

I am trying to validate an alpha-numeric field of length 10 in a catalog item. It's giving me an error even though I have used the alpha-numeric. I am doing this by onChange client script.

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

if (isLoading || newValue == '') {

return;

}

g_form.hideFieldMsg('sap_customer_number');

var patt =new RegExp("^[a-zA-Z0-9]*$");

if (!patt.test(newValue)||patt.length !="10")

g_form.showFieldMsg('sap_customer_number','Invalid input','error');

}

Here are the results when I used this script:

Thanks in Advance,

SD

That's strange, since it worked in my developer instance. Here's the full script:

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

   if (isLoading || newValue == '') {

             return;

   }

   

   g_form.hideFieldMsg('sap_customer_number');

   var patt = new RegExp("^[a-zA-Z0-9]*$");

   if (!patt.test(newValue + '') || newValue.length !="10")

             g_form.showFieldMsg('sap_customer_number','Invalid input','error');

}

The only other thing I did was force newValue to a string in line 8.

Hi,

Try this

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

if (isLoading || newValue === '') {

return;

}

g_form.hideFieldMsg('yourfField');

var patt = "^[a-zA-Z0-9]*$";

if ((!patt.test(newValue)) || pat.length != '10')

g_form.showFieldMsg('yourField', 'Invalid input', 'error');

}

Hello Bharath,

Tried this didn't work. It is no throwing error of the field length increases or decreases 10.

Thanks,

It looks like your second or condition is wrong. Where you have

patt.length !="10"

should be

newValue.length != "10"
