问题描述

当我尝试这个时,HMTL页面只显示最后一个对象,而不是所有的对象。



这是我的JavaScript文件

  var family = {
aaron:{
name:'Aaron',
age:30
},
megan:{
name:'Megan',
age :40
},
aaliyah:{
name:'Aaliyah',
age:2
}
}

var list = function(family){
for(var prop in family){
var elList = document.getElementById('aaron-family')。innerHTML = prop;
}
}

列表(家庭);

这里是我的HTML文件

 < HTML> 
< head>
< title>亚伦的对象测试< / title>
< / head>
< li id =aaron-family>嘿,这是它去的地方< / li>
< footer>
< script src =objects.js>< / script>
< / footer>
< / html>


解决方案

< li> 没有父母< ol> < ul> / code>标签,等等)...但我会说主要的错误是,你将每个后续输出与每个任务分配 innerHTML 。解决方案:将编译数组赋给 innerHTML (使用 join
$ b

  var list = function(family){
var names = [] ;
for(var prop in family){
names.push(prop.name);
}
document.getElementById('aaron-family')。innerHTML = names.join('');
}
list(family);


When I attempt this, the HMTL page only displays the last object, instead of all the objects.

Here is my JavaScript file

var family = {
  aaron: {
    name: 'Aaron',
    age: 30
  },
  megan: {
    name: 'Megan',
    age: 40
  },
  aaliyah: {
    name: 'Aaliyah',
    age: 2
  }
}

var list = function(family) {
  for (var prop in family) {
    var elList = document.getElementById('aaron-family').innerHTML = prop;
  }
}

list(family);

And here's my HTML file

<html>
<head>
  <title>Aaron's Test With Objects</title>
</head>
  <li id="aaron-family">Hey, this is where it goes</li>
<footer>
  <script src="objects.js"></script>
</footer>
</html>

解决方案

Well, you've got a couple problems there (<li> tag without a parent <ol> or <ul> tag, among others)...but I'd say the primary error is that you are replacing each subsequent output with each assignment to innerHTML.

Solution: assign a compiled array to innerHTML (using join to include spaces between the values)

var list = function(family) {
  var names = [];
  for (var prop in family) {
    names.push(prop.name);
  }
  document.getElementById('aaron-family').innerHTML = names.join(' ');
}
list(family);
