如何合并这些复杂的JavaScript数组对象？

Question

Can someone help me to do these example?

var a = ["17","18"];
var b = ["1","1","1"];

I need an output below:

var c = [17:111,18:111]

Answer 1

 var a = ["17","18"]; var b = ["1","1","1"]; var i=0; var ConcateC=""; for(i=0;i< b.length;i++) { ConcateC +=b[i]; } var c=[]; for(i=0;i< a.length;i++) { c[i]=a[i] + ":" + ConcateC; alert(c[i]); } 

Answer 2

You can join the values of b together, then use map to create a new array from the indices of a :

 var a = ["17","18"]; var b = ["1","1","1"]; var bValue = b.join(""); var c = a.map(function(currentValue) { return currentValue + ":" + bValue; }); console.log(c); // ["17:111","18:111"]
