Restrict submit if there are no attachments attached on the form depending on certain conditions

[satya30]

In the form: If the url value is empty it should check if there are any attachments attached. if attachment is there it should submit otherwise it should not submit instead throw an error message.

In the below script that I am writing:

g_form.getUniqueValue() is not giving the record value that is going to be created.( It is giving me sys_id of constant record all the time).

Client Script:

function onSubmit() {
    var url = g_form.getValue('file_upload_url');
    g_form.addInfoMessage(url);

    if (!url) {
        g_form.addInfoMessage("alert2:");

        var sysid = g_form.getUniqueValue();
        alert("Check id = " + sysid);
        var gr = new GlideAjax("sn_customerservice.getAttachmentCount");
		gr.addParam('sysparm_name', 'getCount');
        gr.addParam("sys_attach", sysid);
        gr.getXMLAnswer(validate);

    } 
    function validate(answer) {
        g_form.addInfoMessage("answer" + answer);

        if (answer == false || answer == 'false') {
            alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
            return false;
        } else {
            return true;
        }
    }
}

Script Include:

var getAttachmentCount = Class.create();
getAttachmentCount.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {


    getCount: function() {
        var valid = false;
        var attachId = this.getParameter("sys_attach");
		gs.info("Harika"+attachId);
        var gr = new GlideRecord("sys_attachment");
        gr.addQuery('table_sys_id', attachId);
		gr.query();
		if(gr.getRowCount()>1){
        if (gr.next()) {
			gs.info("Harika"+gr.table_sys_id);
            valid = true;
        }
		}
        return valid;
    },
    type: 'getAttachmentCount'
});

Please help me on how should I achieve this requirement.

This is a record producer form in portal

then use this simple script and it will work in both native and portal

function onSubmit() {
    //Type appropriate comment here, and begin script below
    try {
        var url = g_form.getValue('file_upload_url');
        var count = getRPAttachmentCount();
        if (window == null && url != '') {
            // portal
            if (this.document.getElementsByClassName('get-attachment').length == 0) {
                alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
                return false;
            }
        }
    } catch (ex) {
        // native view
        var url = g_form.getValue('file_upload_url');
        var length = getSCAttachmentCount();
        if (length == 0 && url != '') {
            alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
            return false;
        }
    }
}

function getRPAttachmentCount() {
    var length;
    try {
        length = angular.element("#sc_cat_item_producer").scope().attachments.length;
    } catch (e) {
        length = -1;
    }
    return length;
}
