在选项卡中显示javascript对象

我在下面的代码是一个HTML 页面,其中包含一个标签,我想使用我的JavaScript多维数组,并获取每个名字和年龄,以填充< h3>另外有任何简单的方法来实现这一点任何建议将不胜感激！

function openCity(evt,cityName) {
    var i,tabcontent,tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active","");
    }
    document.getElementById(cityName).style.display = "block";
    evt.currentTarget.className += " active";
}

// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();

var personArr = [];
var person = {firstName:"John",lastName:"Doe",age:21};
var person2 = {firstName:"Paul",lastName:"Logan",age:22};
var person3 = {firstName:"Sean",lastName:"Kim",age:32};
var person4 = {firstName:"Ken",lastName:"Chow",age:12};

personArr.push(person,person2,person3,person4);
console.log(personArr);

body {font-family: Arial;}

/* Style the tab */
.tab {
    overflow: hidden;
    border: 1px solid #ccc;
    background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
.tab button {
    background-color: inherit;
    float: left;
    border: none;
    outline: none;
    cursor: pointer;
    padding: 14px 16px;
    transition: 0.3s;
    font-size: 17px;
}

/* Change background color of buttons on hover */
.tab button:hover {
    background-color: #ddd;
}

/* Create an active/current tablink class */
.tab button.active {
    background-color: #ccc;
}

/* Style the tab content */
.tabcontent {
    display: none;
    padding: 6px 12px;
    border: 1px solid #ccc;
    border-top: none;
}
.line1{
display:inline-block;
}

最佳答案
无需移动HTML,但您可以使用一些类和/或id来使JS更具可读性.
首先,你需要获得所有的h3.这可以通过使用类line1定位父div并获取所有子项来实现.

var parent = document.getElementsByClassName('line1')[0].children;

然后你可以循环这个数组和对象数组来填充所有的innerHTML.在这里小心,你正在添加innerHTML而不是改变它.
这个llop可以通过很多方式实现,我通过循环每2 h3标签并保留一个标记来标记要添加的人

   var personFlag = 0;
    for(var i = 0; i < parent.length; i=i+2){
      parent[i].innerHTML += personArr[personFlag].firstName +' '+personArr[personFlag].lastName;
      parent[i+1].innerHTML += personArr[personFlag].age;
      personFlag++
    }

希望这会有所帮助：>

function openCity(evt,person4);
console.log(personArr);

var parent = document.getElementsByClassName('line1')[0].children;
console.log(parent);
var personFlag = 0;
for(var i = 0; i < parent.length; i=i+2){
  parent[i].innerHTML += personArr[personFlag].firstName +' '+personArr[personFlag].lastName;
  parent[i+1].innerHTML += personArr[personFlag].age;
  personFlag++
}
body {font-family: Arial;}

/* Style the tab */
.tab {
    overflow: hidden;
    border: 1px solid #ccc;
    background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
.tab button {
    background-color: inherit;
    float: left;
    border: none;
    outline: none;
    cursor: pointer;
    padding: 14px 16px;
    transition: 0.3s;
    font-size: 17px;
}

/* Change background color of buttons on hover */
.tab button:hover {
    background-color: #ddd;
}

/* Create an active/current tablink class */
.tab button.active {
    background-color: #ccc;
}

/* Style the tab content */
.tabcontent {
    display: none;
    padding: 6px 12px;
    border: 1px solid #ccc;
    border-top: none;
}
.line1{
display:inline-block;
