In my calculatePercents () method, I should get 0% instead of NULL%.
In my console.log, I get prints with the values NULL
calculatePercents() {
this.v.global.total.amount = this.v.global.cash.amount this.v.global.sec.amount;
console.log("Cash => " JSON.stringify(this.v.global.total.amount));
console.log('------------------------');
this.v.global.cash.percent = (this.v.global.cash.amount / (this.v.global.cash.amount this.v.global.sec.amount)) * 100;
console.log(" Global cash " JSON.stringify(this.v.global.cash.percent));
this.v.global.sec.percent = (this.v.global.sec.amount / (this.v.global.cash.amount this.v.global.sec.amount)) * 100;
console.log(" NULL ???? ==> " JSON.stringify(this.v.global.sec.percent));
var totPercent = (this.v.global.cash.percent this.v.global.sec.percent);
this.v.global.total.percent = totPercent;
}
How I could get a 0 instead of NULL please.
CodePudding user response:
with ||
if the first value is false (converted as boolean) then it will take the second, in that case it's used as a default value.
this.v.global.total.percent = totPercent || 0;
CodePudding user response:
you can use ||
operator to set zero
Eg:
this.v.global.total.percent = (totPercent||0);

CodePudding user response:
You can try this in your method;
if(this.v.global.cash.amount == null){
this.v.global.cash.amount = 0
}
if(this.v.global.sec.amount == null){
this.v.global.sec.amount = 0
}
And then you can do that; (your method)
calculatePercents() {
this.v.global.total.amount = this.v.global.cash.amount this.v.global.sec.amount;
console.log("Cash => " JSON.stringify(this.v.global.total.amount));
console.log('------------------------');
this.v.global.cash.percent = (this.v.global.cash.amount / (this.v.global.cash.amount this.v.global.sec.amount)) * 100;
console.log(" Global cash " JSON.stringify(this.v.global.cash.percent));
this.v.global.sec.percent = (this.v.global.sec.amount / (this.v.global.cash.amount this.v.global.sec.amount)) * 100;
console.log(" NULL ???? ==> " JSON.stringify(this.v.global.sec.percent));
var totPercent = (this.v.global.cash.percent this.v.global.sec.percent);
this.v.global.total.percent = totPercent;
}
And your veriable type is can be "let". Simple Code:
let a = null;
if(a==null){
a=0
}
console.log(a);
// output: 0
