onsubmit client script is not working for attachments in scoped app

[Renu9]

Hi All,

I am having an attachment in record producer in scoped application. It should not allow  more than 1 attachment on submit. Below is the code. But the rowcount is always showing as 0. Please help here

function onSubmit() {

   var proof=g_form.getUniqueValue();  //sys id is displaying

   //var proof = gel('sysparm_item_guid').value;

   alert("proof is " +proof);

   var rowcount=0;

   var attachment = new GlideRecord("sys_attachment");

   attachment.addQuery("table_name", "my table name of record producer");

   attachment.addQuery("table_sys_id", proof);

   attachment.query();

   while(attachment.next())

   {

    rowcount++;

   }

   alert("row count is " +rowcount);   //0 is coming everytime

   if(rowcount >1)

   {

    alert("more than 1 attachment");

    return false;

   }

   else if(rowcount ==1){

    alert("pass");

    return true;

   }

}

Hi @Ankur Bawiskar 

i added the script and i noticed it is not working well in native Ui

it is popping up a message mentioning native ui wont allow window, length, span

i made isolate script as false

Please let me know how this can be resolved

else{
		// native view
         var length = $j("li.attachment_list_items").find("span").length;
		if(length != countRequired){
			alert('You must add 2 attachments before submitting this request.');
			return false;
		}
	}
