本文实例讲述了JS实现从对象获取对象中单个键值的方法。分享给大家供大家参考，具体如下：

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <title>www.vevb.com JS获取对象中单个键值</title></head><body><script>  window.onload = function() {    var add = document.getElementById("addArr")    var arr = [      {aaa: 51, bbb: 174},      {aaa: 270, bbb: 174}    ];    obj = {      xxx: 51,      yyy: 174,      zzz: 175,      aaa: 1,      bbb: "abaababababa",      ccc: 545,      ddd: 2455    };    var aObj = {};    function addArr() {      aObj.aaa = obj.aaa      aObj.bbb = obj.bbb    };    addArr();    add.addEventListener("click", function() {      arr.push(aObj);      console.log(arr);    });  }</script><div>  <button id="addArr">ADD</button></div></body></html>

运行结果：
