Prevent the Submission of Catalog after the false response from Script Incude

[NehaSNOW]

Hi Members,

Below is the Catalag Client Script on onSubmit.

Requirement: - I want to prevent the submission of the Catalog Item if the response from the GlideAjax is false i.e. answer == 'false'. Whereas, the Catalog Item should be submitted if the response from the GlideAjax is true i.e. answer == 'true'.

Please suggest. 

function onSubmit() {

    // Get the values from the form

    var group_name = g_form.getValue('describe_the_change_required_on_the_group');

    var catsys_id = g_form.getUniqueValue();

    // Create the GlideAjax call to get the keyword

    var catKey = new GlideAjax('CatalogKeyword');

    catKey.addParam('sysparm_name', 'getKeyword');

    catKey.addParam('sysparm_cat_sysid', catsys_id);

    catKey.addParam('sysparm_keyword_name', 'group_name_keyword');

    catKey.addParam('sysparm_group_name', group_name);

    // Start the asynchronous GlideAjax call

    catKey.getXMLAnswer(getCatalogKeywordResponse);

    // Prevent form submission until we get the response

    return false;

    // This is the callback function to process the response

    function getCatalogKeywordResponse(answer) {

        g_form.addInfoMessage('answer: ',answer);

        if (answer == 'false') {

            // Validation failed, show an error and prevent form submission

            g_form.addFormMessage('Amazon and AZ keywords are not allowed.','error');

            return false;  // Prevent form submission

        }

        return true;

        // If validation passes, submit the form

        //g_scratchpad.isFormValid = true;

        //g_form.submit();  // Submit the form if validation passes

    }

}

@NehaSNOW  , Try the below code and make sure your script include returning correct output.

function onSubmit() {
    var groupName = g_form.getValue('describe_the_change_required_on_the_group');
    var catSysId = g_form.getUniqueValue();

    // GlideAjax call
    var ga = new GlideAjax('CatalogKeyword');
    ga.addParam('sysparm_name', 'getKeyword');
    ga.addParam('sysparm_cat_sysid', catSysId);
    ga.addParam('sysparm_keyword_name', 'group_name_keyword');
    ga.addParam('sysparm_group_name', groupName);

    // Async call with callback
    ga.getXMLAnswer(function(answer) {
        if (answer === 'false') {
            g_form.addErrorMessage('Amazon and AZ keywords are not allowed.');
        } else if (answer === 'true') {
            g_form.submit(); // Resubmit if valid
        } else {
            g_form.addErrorMessage('Validation failed. Please try again.');
        }
    });

    // Always block until Ajax callback decides
    return false;
}

@Shashank_Jain Thanks for your response. Issue is it is block me to go to the Next page to submit the REQ when the answer === 'true'. PFA.

@NehaSNOW , Try this!

var isValidationInProgress = false;
var isValidationPassed = false;

function onSubmit() {
    // If validation already passed once → allow submission
    if (isValidationPassed) {
        return true;
    }

    // Prevent multiple Ajax calls
    if (isValidationInProgress) {
        return false;
    }

    isValidationInProgress = true;

    var groupName = g_form.getValue('describe_the_change_required_on_the_group');
    var catSysId = g_form.getUniqueValue();

    var ga = new GlideAjax('CatalogKeyword');
    ga.addParam('sysparm_name', 'getKeyword');
    ga.addParam('sysparm_cat_sysid', catSysId);
    ga.addParam('sysparm_keyword_name', 'group_name_keyword');
    ga.addParam('sysparm_group_name', groupName);

    ga.getXMLAnswer(function(answer) {
        isValidationInProgress = false; // reset flag

        if (answer === 'false') {
            g_form.addErrorMessage('Amazon and AZ keywords are not allowed.');
            // stay blocked
        } else if (answer === 'true') {
            isValidationPassed = true; // mark validation success
            g_form.submit(); // submit again → this time bypasses validation
        } else {
            g_form.addErrorMessage('Validation failed. Please try again.');
        }
    });

    return false; // block until Ajax decides
}
