进入HTML表格，如下所示

<table>
   <tr>
      <th>firstName</th>
      <th>last Name</th>
      <th>age</th>
   </tr>
   <tr>
      <td>John</td>
      <td>Doe</tD>
      <td>46</th>

      <td>James</td>
      <td>Blanc</tD>
      <td>24</th>
   </tr>
</table>

提前致谢。

Answer 1

您可以使用forEach方法执行此操作，该方法接受callback提供的函数作为参数。

＆＃13;

var users=[{"firstName":"John", "last Name":"Doe", "age":"46"},
 {"firstName":"James", "last Name":"Blanc", "age":"24"}]
users.forEach(function(item){
  $('tbody').append('<tr><td>'+item.firstName+'</td><td>'+item["last Name"]+'</td><td>'+item.age+'</td></tr>')
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<th>firstName</th>
<th>last Name</th>
<th>age</th>
</tr>
</thead>
<tbody>

</tbody>
</table>

＆＃13;

Answer 2

试试这段代码：

＆＃13;

var rows = [{"firstName":"John", "last Name":"Doe", "age":"46"},
 {"firstName":"James", "last Name":"Blanc", "age":"24"}];
 var html = '<table>';
 html += '<tr>';
 for( var j in rows[0] ) {
  html += '<th>' + j + '</th>';
 }
 html += '</tr>';
 for( var i = 0; i < rows.length; i++) {
  html += '<tr>';
  for( var j in rows[i] ) {
    html += '<td>' + rows[i][j] + '</td>';
  }
 }
 html += '</table>';
 document.getElementById('container').innerHTML = html;

＆＃13;

<div id="container">
</div>

＆＃13;

Answer 3

在您的HTML下面放置代码

<div id="myTable">

</div>

并在脚本中放下代码

var arrObj = [{"firstName":"John", "lastName":"Doe", "age":"46"},
 {"firstName":"James", "lastName":"Blanc", "age":"24"}]
 var objLength = arrObj.length;
var myvar = '<table>'+
'<tr>'+
'<th>firstName</th>'+
'<th>last Name</th>'+
'<th>age</th>'+
'</tr>';

 for(var i = 0; i < objLength; i++){
myvar += '<tr>'+
'<td>'+arrObj[i].firstName+'</td>'+
'<td>'+arrObj[i].lastName+'</tD>'+
'<td>'+arrObj[i].age+'</th>'+
'</tr>'     
 }

 myvar += '</table>';

console.log(myvar);
 document.getElementById('myTable').innerHTML = myvar;

希望这有效

Answer 4

普通JS，在元素中显示“ arrayOfData”的内容：

<pre id="jsarray"></pre>

通过使用以下代码：

document.getElementById("jsarray").textContent = JSON.stringify(arrayOfData, undefined, 2);

使用jQuery或Javascript将对象数组转换为HTML表
