Define the below mentioned function for check the variable has value or not. If variable has value, the function will return true. Otherwise, it will return false.
function checkForParameter(parameter) {
if (parameter! == “” && parameter! == null && parameter! == undefined && parameter! == false && parameter! == “null” && parameter! == “undefined” && parameter! == ” ” && parameter! == ‘false’) {
return true;
} else {
return false;
}
}
sgstAmount is the variable. Function is checking variable has a value or not. If sgstAmount has value, it will enter to function and perform the operation. Otherwise, it will skip the function. For example,
Var sgstAmount = customRec.getvalue({
fieldId: ‘total’,
id: ‘id’
})
if(checkForParameter(sgstAmount)){
totSgst=totSgst+sgstAmount;
log.debug(“totSgst”, totSgst)
}
