js 遍历数组生产对象

在JavaScript中，遍历数组可以通过使用for循环来实现。可以使用以下代码来遍历数组并生成对象：

var arr = [1, 2, 3, 4, 5];
var obj = {};

for (var i = 0; i < arr.length; i++) {
  obj[arr[i]] = i;
}

console.log(obj);

上述代码首先创建了一个空对象`obj`。然后，通过for循环遍历数组`arr`，将数组中的每个元素作为对象`obj`的键，对应的索引作为值。最后，打印输出对象`obj`。

这样，你就可以使用JavaScript遍历数组生成对象了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
