Check attachment file type-client script

[Sin]

Hi All,

I have written a client script to restrict attachment file types.I want to allow users to attach only .csv file types.

written code for both portal and non-portal, On portal its working as expected indexOf returns different value for all csv attachments.

On non-portal indexOf  returns -1 for all type of attachments. (jpg,pdf,xml.csv..)

function onSubmit() {
try
{
//for non-portal
var sysid =g_form.getElement('sysparm_item_guid').value;
var rowcount=0;
var attachment = new GlideRecord("sys_attachment");
attachment.addQuery("table_name", "sc_cart_item");
attachment.addQuery("table_sys_id", sysid);
attachment.query();
while (attachment.next()) {
rowcount++;
}
if(rowcount != 1)
{
if(rowcount==0)
alert("Attachment Required!!");
return false;
}
else if(rowcount == 1 && attachment.content_type.indexOf(".csv") <= -1){
alert(attachment.content_type);
alert("Attachment should be in only csv format!");
return false;
}
else return true;

}

catch(e)

{
//for-portal
if(this.document.getElementsByClassName('get-attachment').length ==1) {
var value = (this.document.getElementsByClassName('get-attachment')[0].innerHTML).toLowerCase();
alert(value.indexOf('.csv'));
if ((value.indexOf('.csv')>-1)){
return true;
}
else
{
alert ("Attachment should be in only csv format!");
return false;
}
}
else if(this.document.getElementsByClassName('get-attachment').length <1)
{
alert( "Attachment Required!!");
return false;
}

}

Is there anything wrong in my code?Need some suggestion.

Thanks in Advance!

Hi Ankur, I am trying to do same but allowing user to enter .txt file only. Could you please check my code why its not working? it is accepting all the files.

var sysid =g_form.getElement('sysparm_item_guid').value;
alert(sysid );
var attachment = new GlideRecord("sys_attachment");
attachment.addQuery("table_name", "sc_cart_item");
attachment.addQuery("table_sys_id", sysid);
attachment.query();
var rowcount= attachment.rows.length;
var file = attachment.file_name; // this is not working
alert(rowcount);
alert(file); // alert is not working

alert(attachment.content_type) // this is coming as undefined

if(rowcount==0 )
{
alert("Attachment Required!!");
return false;
}
else if(rowcount == 1 && attachment.content_type.indexOf(".txt") >= -1){

alert("Attachment should be in only txt format!");
return false;
}

@sraj 

It is not recommended to use GlideRecord in client script

Issue is in code after while loop.

function onSubmit() { 
try
{
//for non-portal
var sysid =g_form.getElement('sysparm_item_guid').value;
var rowcount=0;
var attachment = new GlideRecord("sys_attachment");
attachment.addQuery("table_name", "sc_cart_item");
attachment.addQuery("table_sys_id", sysid);
attachment.query();
while (attachment.next()) {
rowcount++;
}

if(rowcount==0){ // Missing {}
alert("Attachment Required!!");
return false; 
}
if(rowcount == 1 && attachment.content_type.indexOf(".csv") <= -1){
alert(attachment.content_type);
alert("Attachment should be in only csv format!");
return false; 
}
else return true;

}


catch(e)

{ 
//for-portal
if(this.document.getElementsByClassName('get-attachment').length ==1) {
var value = (this.document.getElementsByClassName('get-attachment')[0].innerHTML).toLowerCase();
alert(value.indexOf('.csv'));
if ((value.indexOf('.csv')>-1)){
return true;
} 
else
{
alert ("Attachment should be in only csv format!"); 
return false;
}
}
else if(this.document.getElementsByClassName('get-attachment').length <1)
{
alert( "Attachment Required!!");
return false;
}

}
