Check for a single character validation upon selecting the choice in another variable.

[satya30]

Hi All,

Please help me and thanks in advance.

The requirement is on change of yes or no variable, the code that is entered on another variable needs to be validated. 
ie. If yes is selected for choice the  code variable needs to have a k in the entered code. This is required

Below is the script that I tried.

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

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

        return;

    }

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

        g_form.addInfoMessage("newValue: " + newValue);

        var Code = g_form.getValue('code');

               g_form.addInfoMessage("Code: " + Code);

        if (Code.includes('k')) {

            g_form.addInfoMessage('code contains "k": ' + Code);

            g_form.hideFieldMsg('code');

        } else {

            g_form.addInfoMessage('code does NOT contain k ');

            var msg = 'code must contain an "k"';

            g_form.setValue('code', '');  

            g_form.showFieldMsg('code', msg, 'error');

        }

    } else {

         g_form.hideFieldMsg('code');

    }

}

try this

It's yes no variable so it won't give true/false value

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    if (newValue == 'yes') {
        var Code = g_form.getValue('code');
        if (Code.indexOf('k') > -1) {
            g_form.hideFieldMsg('code');
        } else {
            var msg = 'code must contain an "k"';
            g_form.showFieldMsg('code', msg, 'error');
            g_form.clearValue('code');
        }
    } else {
        g_form.hideFieldMsg('code');
    }
}

As you saying its yes no variable why you are checking true false value. First try to see what value is coming in newvalue when options are selected and on basis of that proceed with your logic.
