for example I can't reach 'this.ret' so use 'obj.ret' in loop.
is this right way?
const obj = {
ret : 0,
sum : function(arr){
$.each(arr, function(i, v){
obj.ret += v //Can't reach this.ret
})
this.print();
},
print : function(){
alert('sum is ' + this.ret)
}
}
let arr = [1,2,3,4,5]
obj.sum()
You can use Arrow Function
const obj = {
ret : 0,
sum : function(arr){
$.each(arr, (i, v) => {
this.ret += v
})
this.print();
},
print : function(){
console.log('sum is ' + this.ret)
}
}
let arr = [1,2,3,4,5]
obj.sum(arr)<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>const obj = {
ret : 0,
sum : function(arr){
$.each(arr, function(i, v){
obj.ret += v //Can't reach this.ret
})
this.print();
},
print : function(){
console.log('sum is ' + this.ret)
}
}
let arr = [1,2,3,4,5]
obj.sum(arr)<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>change obj.sum() to obj.sum(arr)
