Hi All,

 

I have a urgent Requirement, Help text (label variable) is not Visible on service portal based on drop down changes,

Example : I have drop down variable in service catalog, in drop down x and y choices when i am selecting x, (label variable) help text  is should be not visible , when i am selecting the y help text should be visible on service portal and itil view also, but it's not working as excepted 

I have written on change catalog script :

 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    if (newValue == 'vendor') {
        alert('test');
        g_form.showFieldMsg('payments_label', 'Please search invoice in the Report/SearchReport/Search tab in My Payables before submitting ticket.', 'info', true);
    } else {
        g_form.hideFieldMsg('payments_label', 'Please search invoice in the Report/SearchReport/Search tab in My Payables before submitting ticket.');
        }
    }

Hi @karishma shaik ,

 

Use g_form_getField("<fieldname>").placeholder to change the example text dynamically in a portal.

Use g_form.getControl("<fieldname>").placeholder to change the example text dynamically in the Now platform.

Please try the below code-

 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var infoField = g_form.getField("payments_label");

    if (newValue == 'vendor') {
        infoField.expand_help = true;
        infoField.instructions = "<p>Please search invoice in the Report/SearchReport/Search tab in My Payables before submitting ticket.</p>";
    } else {
        infoField.expand_help = true;
        infoField.instructions = "<p></p>"; // Clear the help text by setting an empty paragraph
    }
}

 

 

Or try this-

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

    var infoField = g_form.getField("payments_label");

    if (newValue == 'vendor') {
        infoField.expand_help = true;
        infoField.instructions = "<p>Please search invoice in the Report/SearchReport/Search tab in My Payables before submitting ticket.</p>";
        infoField.help_tag = "More information";
    } else {
        infoField.expand_help = true;
        infoField.instructions = "<p></p>"; // Clear the help text by setting an empty paragraph
        infoField.help_tag = "";
    }
}

 

If the above doesn't work try to take a look into these below posts-
