循环中的动态变量名称

Question

我需要在js里面为for循环创建动态变量名

var counter = 0;
for(i=0; i<location.length; i++) {
   ...
   var "marker_" + counter = new google.maps.Marker({

但是,当我期望变量marker_0,marker_1,marker_2,...时,我有这个错误

Error: SyntaxError: missing variable name
Source Code:
          var "marker_" + counter = new google.maps.Marker({ 

Answer 1

使用数组:

var marker = [];

for (i=0; i < location.length; i++) {
   marker[counter] = new google.maps.Marker({
