在Js中，如何将两个list：list1=[a,b,c,d]；list2=[1,2,3,4]，遍历拼接为list3=[{a:1},{b:2},{c:3},{d:4}]？

Answer 1

function arrcat(arr1,arr2){
if(!Array.isArray(arr1) || !Array.isArray(arr2) || arr1.length != arr2.length) return [];
var arr = [];
for(var i = 0,len = arr1.length;i<len;i++){
var obj = new Object();
obj[arr1[i]] = arr2[i];
arr[i]=obj;
}
return arr;
}
arrcat(["a","b","c","d"],[1,2,3,4]);//结果：[{a:1},{b:2},{c:3},{d:4}]
