Check if some of the characters are numbers

user_ms · ‎01-15-2024

Extract characters and check if the extracted value is a number.

If there is the following value, I want to extract the first 3 characters and determine whether the value is a number.
123-456

If there is no number, print an error message in the field.

Other conditions
Use Client Script
Check with onSubmit

Please let me know if you know.

@user_ms Here is the script

function onSubmit() {
   //Type appropriate comment here, and begin script below
	var textBox= g_form.getValue('text_box');
	var pattern = /^\d{3}-/;
	if(pattern.test(textBox)){
		g_form.showFieldMsg('text_box','correct');
	}
	else{
		g_form.showFieldMsg('text_box','incorrect');
	}
	return false;
}

hi

function onSubmit() {

var fieldValue = g_form.getValue('your_field');

var firstThreeChars = fieldValue.substring(0, 3);

if (!isNaN(firstThreeChars)) {

} else {

g_form.addErrorMessage("The first three characters must be a number.");
return false;
}
