javascript - 在 for 循环中创建对象语法错误

Question

我在 for 循环中定义对象的行的以下代码中遇到语法错误。这里出了什么问题？

var NAMES     = [ 'Accessories', 'Basins' ];      
var VARIANTS  = [ ['red','green','blue'], ['red','green','blue'] ];  
var numGroups = AD_GROUP_NAMES.length;
var INFO      = [];

for (var x = 0; x =< numGroups; x++) {
    var obj = { name : NAMES[x], variants : VARIANTS[x] };
    INFO.push(obj);
}

有什么想法吗？任何帮助表示赞赏。

将比较运算符从 =< 更改为至>= .

您还应该设置 numGroups长度 - 1: var numGroups = AD_GROUP_NAMES.length - 1;

var NAMES     = [ 'Accessories', 'Basins' ];      
var VARIANTS  = [ ['red','green','blue'], ['red','green','blue'] ];  
var numGroups = 1 ;//AD_GROUP_NAMES.length - 1;
var INFO      = [];

for (var x = 0; x <= numGroups; x++) {
    var obj = { name : NAMES[x], variants : VARIANTS[x] };
    INFO.push(obj);
}

console.log(INFO);
