如何使用JavaScript从此字符串中读取agent_code？请解释我的逻辑。
JSON（单行）：

让我们说你的上面是一个json字符串
var jsonString = '[{"name":"NYC","zone_id":"1","totalagents":"40","agents":[{"id":"1","agent_code":"====="},{"id":"2","agent_code":"====="},{"id":"3","agent_code":"Christian"},{"id":"4","agent_code":"Tom"},{"id":"5","agent_code":"Dave Damsky"},{"id":"6","agent_code":"====="},{"id":"7","agent_code":"Andrew"},{"id":"8","agent_code":"Paolo"},{"id":"9","agent_code":"Josh"},{"id":"10","agent_code":"Shipster Van"},{"id":"11","agent_code":"====="},{"id":"16","agent_code":"Christian2"},{"id":"20","agent_code":"Nathan"},{"id":"21","agent_code":"Aaron"},{"id":"22","agent_code":"Rob"},{"id":"23","agent_code":"Taylor"},{"id":"24","agent_code":"Drea"},{"id":"25","agent_code":"Mario "},{"id":"26","agent_code":"Julio"},{"id":"27","agent_code":"Abbas"},{"id":"28","agent_code":"Ahmed"},{"id":"29","agent_code":"David Damsky"},{"id":"30","agent_code":"Micheal"},{"id":"31","agent_code":"Moe"},{"id":"32","agent_code":"Luis"},{"id":"33","agent_code":"Darin"},{"id":"37","agent_code":"Alan"},{"id":"39","agent_code":"Cristian Marte"},{"id":"40","agent_code":"Cody"},{"id":"41","agent_code":"David Pinto"},{"id":"42","agent_code":"Will "},{"id":"44","agent_code":"Evan"},{"id":"45","agent_code":"Santiago"},{"id":"46","agent_code":"John"},{"id":"47","agent_code":"Moubeen"},{"id":"49","agent_code":"Devin Armstrong"},{"id":"50","agent_code":"Marco Bell"},{"id":"51","agent_code":"Youness Benzaid"},{"id":"52","agent_code":"Amin Mechouche"},{"id":"53","agent_code":"Franco Herrera"}]}]';
var json = JSON.parse(jsonString); // parse string into json
现在这个json是一个长度为1的数组，要获取所有代理代码，你必须做这样的事情。
for (var i = 0; i <json[0].agents.length; i++) {
console.log(json[0].agents[i].agent_code);
}
