How to Restrict Start and End Spaces in string

[rambabu1]

Hi,

Using below script unable to restrict spaces in start and end of string. it's working only if the space in middle of the string.

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

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

if (!regx.test(newValue)) {

alert('No Special Chars are allowed except "_" and "-"');
g_form.setValue('name', '');
}
}

Hello,

You can use this as an example of regex: https://stackoverflow.com/questions/34974942/regex-for-no-whitespace-at-the-beginning-and-end#:~:tex...

And then make any further adjustments needed to allow your special characters.

Please mark reply as Helpful/Correct, if applicable. Thanks!

please see the screenshot as well

var regx = /^[A-Za-z0-9_-\s]*$/;
var res = g_form.getValue('name');
var name = res.replace(' ', '');

if (!regx.test(newValue)) {
