Validate alpha numeric on a field in catalog item

[SD29]

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 Fred,

Is there any possibility that we can get this on OnSubmit() Client script?

I wrote the following code but it is still submitting.

function onSubmit() {

    //Type appropriate comment here, and begin script below

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

  var projectKey=g_form.getValue('project_key');

  alert("value"+projectKey);

  var res=alpha.test(projectKey);

  if (!res) {

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

  }

}

  }

  g_form.hideFieldMsg('sap_customer_number');

  if(/^[0-9a-zA-Z]+$/.test(newValue) && newValue.length==10){

  g_form.hideFieldMsg('sap_customer_number');

  }

  else{

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

Can you try

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
       return;
   }

   g_form.hideFieldMsg('sap_customer_number');
   if (!/^[a-zA-Z0-9]{10}$/.test(newValue))
       g_form.showFieldMsg('sap_customer_number','Invalid input','error');
}

Hope this helps.

You can simplify your test logic by checking for the length in RegEx using "{10}", which says "match exactly 10 times."
