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.

it should work fine

try this

function onSubmit() {
    //Type appropriate comment here, and begin script below

    if (g_form.getValue('file_upload_url').toString() != '') {
        try {
            if (window == null) {
                // 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 length = $j("li.attachment_list_items").find("span").length;
            if (length == 0) {
                alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
                return false;
            }
        }

    }
}

I don't think the below piece of code is working correctly. I tried multiple scripts and then using the script include where it passes the uniqueValue of the record

if (this.document.getElementsByClassName('get-attachment').length == 0) {

@satya30 

that's what I already shared and this will work fine in Portal

For native I am still checking

this worked for both native and portal

Ensure Isolate Script = False for your client script

function onSubmit() {
    //Type appropriate comment here, and begin script below

    if (window == null) {
        // portal
        var count = this.document.getElementsByClassName('get-attachment').length;
        if (count == 0) {
            alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
            return false;
        }
    } else {
        // native view
        var length = $j("li.attachment_list_items").find("span").length;
        if (length == 0) {
            alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
            return false;
        }
    }

}

Output:

I believe I have answered your question.
