Script include sysparm

[Indira8]

Could someone please help me explain  what is sysparm_serial in the following script:

checkAssetSerial: function() {
var sno = this.getParameter("sysparm_serial");
var gr1 = new GlideRecord('alm_hardware');

gr1.addQuery('serial_number', sno);
gr1.query();
if (gr1.next()) {
return true;

} else {

return false;
}

Thank you

It is the parameter name that a ajax client script sent to the function.

Please refer to client script and ajax calls.

It's a custom name (i.e. non-ServiceNow default) of a parameter that the developers of the script named to get a value of a serial number to query hardware asset table. If the serial number already exists in the hardware asset table, the function will return true. Otherwise, the function returns false.

Client script will call function checkAssetSerial() by setting this parameter.

.addParam('sysparm_serial', <serial number of hardware to check>);
