Regex to accept numbers and can only accept one dot for decimals.

[pardhiv]

I am trying to write a regex with on change client and tried the below. It needs to accept numbers as below

ex: (should accept numbers and dots)

12345

12345.67

12345.678xxx (No limitation on decimals unless its not possible)

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   //Accept numbers with only dots
   var pattern =  /^(([0-9.]?)*)+$/;  
    if (!pattern.test(newValue)) {
		g_form.clearValue('u_amount');
        g_form.showFieldMsg('u_amount', 'Accepted format : 354621.32', 'error', true);
        
    } 
   
}

@pardhiv What is the issue here, your regex is working accepting number and dot. Is it not working in client script?

[pardhiv]

It isn't accepting both the inputs I gave in the question.  I don't have any limitation on number of decimal places. If there is no option , I can stick with 2 places

@pardhiv I tested on my PDI and it is just working fine for me with both the inputs 1234 and 1234.12.

Please clear your cache of the browser and then check as the script is working just fine.

Seems like the Issue is with my client script , I tried multiple regex and they been clearing out values.
