onsubmit client script for attachments without getelement

[Nitya2]

We are using below catalog client script for  mandatory attachments , but as per best practices servicenow asking us to use without gel function in 5th line (var cat_id = gel('sysparm_item_guid').value;)

kindly help me to change below code  without gel method

function onSubmit() {
//Type appropriate comment here, and begin script below
var condtn = g_form.getValue('Server_com_decom');
if(condtn == 'Commission'){
var cat_id = gel('sysparm_item_guid').value;
var gr = new GlideRecord("sys_attachment");
gr.addQuery("table_name", "sc_cart_item");
gr.addQuery("table_sys_id", cat_id);
gr.query();
if (!gr.next()) {
alert("You must attach a file to submit.");
return false;
}
}
}

Hi,

Try this:

var OwnOther = g_form.getValue('Server_com_decom');
if (OwnOther == 'Commission') {

var sysid = g_form.getUniqueValue();

  var attach = new GlideRecord('sys_attachment');

  attach.addQuery('table_sys_id',sysid);

  attach.query();

  if(attach.next()){

  alert("You must add attachment before submitting this request.");

return false;

  }

}

Hi 

Give a final try:

function onSubmit() {

var OwnOther = g_form.getValue('Server_com_decom');
if (OwnOther == 'Commission') {
var cat_id = g_form.getValue('sysparm_item_guid');
var gr = new GlideRecord("sys_attachment");
gr.addQuery("table_name", "sc_cart_item");
gr.addQuery("table_sys_id", cat_id);
gr.query();
if (!gr.next()) {
          alert("You must add an attachment before submitting this request.");
          return false;
         }
}

}

Thanks

Hi Nitya,

Refer link for a check as it has all possible options.

Hi Nitya

You can replace the below line

var cat_id = gel('sysparm_item_guid').value;

with

var cat_id = g_form.getValue('sysparm_item_guid');
