Display Field Message (error) when past date selected on Date Type Variable

[rishabh31]

Dear Team,

Please help here.

Currently, the below onChange Client Script (script include called) is functioning fine, but NOT displaying an error field message just below the Variable (date_to_disable_account)

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

    var disDate = new GlideAjax('validateDisableDate');
    disDate.addParam('sysparm_name', 'nowDateTime');
    disDate.addParam('sysparm_disable_date', g_form.getValue('date_to_disable_account'));
    disDate.getXML(compareDisableDate);

    function compareDisableDate(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        if (answer < 0) { //To allow current date but not past date
            //g_form.addErrorMessage("Date to Disable Account should not be the Past Date");
            g_form.showFieldMsg('date_to_disable_account', 'Date to Disable Account should not be the Past Date', 'error');
            g_form.clearValue('date_to_disable_account');
        }
    }
}

See, addErrorMessage is working fine, but it displays an error msg at the top of the catalog form (which is not desired) and clears this variable date value (which is functioning fine).

I want to display an error message just below the variable (date_to_disable_account) on the catalog form, so I used showFieldMsg and tested in catalog form by choosing any past date and found it functions only to clear the date value but NOT DISPLAYING any error field message in the highlighted area (below the variable).

Requesting to please help to get field message (error) display below the variable.

Thank You

Hi @rishabh31 

Check with below script

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

    var disDate = new GlideAjax('validateDisableDate');
    disDate.addParam('sysparm_name', 'nowDateTime');
    disDate.addParam('sysparm_disable_date', g_form.getValue('date_to_disable_account'));
    disDate.getXML(compareDisableDate);

    function compareDisableDate(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");

        if (answer < 0) { //To allow current date but not past date
            //g_form.addErrorMessage("Date to Disable Account should not be the Past Date");
          
            g_form.clearValue('date_to_disable_account');
           g_form.showFieldMsg('date_to_disable_account', 'Date to Disable Account should not be the Past Date', 'error');
        }
    }
}

Hi @Manmohan K ,

Thank You🙂, your provided script where lines just interchanged is working fine.

But I am wondering why earlier it was not working as all things (syntax, method etc) are correct, so how does interchanging the lines make it work, please explain.

Marking your response as correct and helpful.

 If you try to clear the value using  g_form.clearValue(..) straight after the g_form.showFieldMsg(..) it will not display the error message as clearValue overrides the changes done by showFieldMsg function.

Instead clear the value prior to displaying the error message for getting expected results

Hi @rishabh31 ,
Can you please try with:

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

    var disDate = new GlideAjax('validateDisableDate');
    disDate.addParam('sysparm_name', 'nowDateTime');
    disDate.addParam('sysparm_disable_date', g_form.getValue('date_to_disable_account'));
    disDate.getXML(compareDisableDate);

    function compareDisableDate(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");

        if (parseInt(answer) < 0) { //To allow current date but not past date
            g_form.clearValue('date_to_disable_account');
           g_form.showFieldMsg('date_to_disable_account', 'Date to Disable Account should not be the Past Date', 'error');
        }
    }
}
