如何使用node-js从json文件构建html表？我有一个JSON文件，我想把它显示在html文档中，我该怎么做？
试试这个：
<!DOCTYPE html>
<html>
<head>
<title>Convert JSON Data to HTML Table</title>
<style>
th, td, p, input, h3 {
font:15px 'Segoe UI';
}
table, th, td {
border: solid 1px #ddd;
border-collapse: collapse;
padding: 2px 3px;
text-align: center;
}
th {
font-weight:bold;
}
</style>
</head>
<body>
<h3>
Click the button to create a dynamic table using data extracted from a JSON array.
</h3>
<input type='button' onclick='tableFromJson()'
value='Create Table from JSON data' />
<p id='showData'></p>
<p id='msg'></p>
</body>
<script>
// scroll down for ES6 features.
// using regular methods.
function tableFromJson() {
// the json data. (you can change the values for output.)
var myBooks = [
{'Book ID': '1', 'Book Name': 'Challenging Times',
'Category': 'Business', 'Price': '125.60'
},
{'Book ID': '2', 'Book Name': 'Learning JavaScript',
'Category': 'Programming', 'Price': '56.00'
},
{'Book ID': '3', 'Book Name': 'Popular Science',
'Category': 'Science', 'Price': '210.40'
}
]
// Extract value from table header.
// ('Book ID', 'Book Name', 'Category' and 'Price')
var col = [];
for (var i = 0; i < myBooks.length; i++) {
for (var key in myBooks[i]) {
if (col.indexOf(key) === -1) {
col.push(key);
}
}
}
// Create a table.
var table = document.createElement("table");
// Create table header row using the extracted headers above.
var tr = table.insertRow(-1); // table row.
for (var i = 0; i < col.length; i++) {
var th = document.createElement("th"); // table header.
th.innerHTML = col[i];
tr.appendChild(th);
}
// add json data to the table as rows.
for (var i = 0; i < myBooks.length; i++) {
tr = table.insertRow(-1);
for (var j = 0; j < col.length; j++) {
var tabCell = tr.insertCell(-1);
tabCell.innerHTML = myBooks[i][col[j]];
}
}
// Now, add the newly created table with json data, to a container.
var divShowData = document.getElementById('showData');
divShowData.innerHTML = "";
divShowData.appendChild(table);
}
</script>
