JSON is usually used to exchange data with the server.

JSON.stringify() syntax

When sending data to the server, it is usually a string.

We can use the JSON.stringify() method to convert JavaScript objects into strings.

JSON.stringify() example

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php.cn</title>
</head>
<body>

<h2>将 JavaScript 对象转换Wie JSON 字符串</h2>

<p id="demo"></p>

<script>

var obj = { "name":"php.cn", "alexa":10000, "site":"www.php.cn"};
var myJSON = JSON.stringify(obj);
document.getElementById("demo").innerHTML = myJSON;

</script>

</body>
</html>
