Need assistance with onsubmit client script

[Community Alums]

Hi all, 

Instead of getXML(), I want to use getXMLWait(), Can you please help, I dont knoe the syntax how to use it. FYR: answer1 is returning an array.

function onSubmit() {
    if (g_scratchpad.isFormValid) {
        return true;
    }
    var flagArray = [];
    var flag = 'false';
var name1 = g_form.getValue('papplication_name');
    var ga = new GlideAjax('global.ClientScriptName');
    ga.addParam('sysparm_name', 'getVariablefromItem');
    ga.addParam('sysparm_catupdte', name1);
    ga.getXML(catupdateResponse1);
    return false;

    function catupdateResponse1(response1) {
    var answer1 = response1.responseXML.documentElement.getAttribute("answer");
    answer1 = JSON.parse(answer1);
    for (var i = 0; i < answer1.length; i++) {
        var namefield = answer1[i].toString();
        if (g_form.getValue(namefield)) {
            flag = 'true';
            break;
        }
    }
    if (flag == 'false') {
        g_form.addErrorMessage('No need to submit');
        return false;
    }
    var actionName = g_form.getActionName();
    g_scratchpad.isFormValid = true;
    g_form.submit(actionName);
}
}

Hello @Community Alums 

function onSubmit() {
    if (g_scratchpad.isFormValid) {
        return true;
    }
    var flagArray = [];
    var flag = 'false';
var name1 = g_form.getValue('papplication_name');
    var ga = new GlideAjax('global.ClientScriptName');
    ga.addParam('sysparm_name', 'getVariablefromItem');
    ga.addParam('sysparm_catupdte', name1);
    ga.getXMLWait(catupdateResponse1);
    return false;

    function catupdateResponse1(response1) {
    var answer1 = response1.responseXML.documentElement.getAttribute("answer");
    answer1 = JSON.parse(answer1);
    for (var i = 0; i < answer1.length; i++) {
        var namefield = answer1[i].toString();
        if (g_form.getValue(namefield)) {
            flag = 'true';
            break;
        }
    }
    if (flag == 'false') {
        g_form.addErrorMessage('No need to submit');
        return false;
    }
    var actionName = g_form.getActionName();
    g_scratchpad.isFormValid = true;
    g_form.submit(actionName);
}
}

Plz mark my solution as Accept, If you find it helpful.

Hi @Community Alums ,

To use `getXMLWait()` instead of `getXML()` in your ServiceNow client script, you'll need to make some adjustments to your existing code. The `getXMLWait()` method is synchronous and will block until the response is received. Here's an updated version of your script:

function onSubmit() {

    if (g_scratchpad.isFormValid) {

        return true;

    }

    var flagArray = [];

    var flag = 'false';

    var name1 = g_form.getValue('papplication_name');

    var ga = new GlideAjax('global.ClientScriptName');

    ga.addParam('sysparm_name', 'getVariablefromItem');

    ga.addParam('sysparm_catupdte', name1);

    // Use getXMLWait() instead of getXML()

    var response1 = ga.getXMLWait();

    catupdateResponse1(response1);

    return false;

    function catupdateResponse1(response1) {

        var answer1 = response1.responseXML.documentElement.getAttribute("answer");

        answer1 = JSON.parse(answer1);

        for (var i = 0; i < answer1.length; i++) {

            var namefield = answer1[i].toString();

            if (g_form.getValue(namefield)) {

                flag = 'true';

                break;

            }

        }

        if (flag == 'false') {

            g_form.addErrorMessage('No need to submit');

            return false;

        }

        var actionName = g_form.getActionName();

        g_scratchpad.isFormValid = true;

        g_form.submit(actionName);

    }

}

In this version:

- The `getXML()` method is replaced with `getXMLWait()`.

- The `catupdateResponse1` function is still used as the callback for processing the response.

- The rest of the code remains largely unchanged.

Keep in mind that using `getXMLWait()` is a synchronous operation, and it may impact the user experience if there is a delay in the response. Ensure that it aligns with your application's requirements and performance considerations.

Thanks,

Danish
