The following code takes an array of objects structured like so: {html: whatever number: number value }.
function Org(data){
//array of objects
var Data=data;
for(var i=0; i<Data.length; i++){
var nums=[];
nums.push(Data[i].number);
console.log(nums);}
}
Nums should have be logged to the console as [1,1] on the second iteration when called with: [{html:null,number:1},{html:null,number:1}] but instead is logged as [1] on both the first and second iterations. Why might this be?
You need to move the initialization of num
outside of the for
loop. Inside it creates for each iteration a new empty array.
BTW, no need for using another variable for data
.
function Org(data){
var nums = [];
for (var i = 0; i < data.length; i++){
nums.push(data[i].number);
}
console.log(nums);
}
或更短:
var Org=data=>console.log(data.map(e=>e.number));
