我收到此错误: [object Object]、[object Object]、[object Object]。
我想显示完整的数组，如下所示:John Doe, Anna Smith, Peter Jones
<!DOCTYPE html>
<html>
<body>
<h2>Create Object from JSON String</h2>
<p id="demo"></p>
<script>
var text = '{"employees":[' +
'{"firstName":"John","lastName":"Doe" },' +
'{"firstName":"Anna","lastName":"Smith" },' +
'{"firstName":"Peter","lastName":"Jones" }]}';
obj = JSON.parse(text);
document.getElementById("demo").innerHTML =
obj.employees;
</script>
</body>
</html>最佳答案
您可以使用Array#map并构建一个新数组并稍后加入它。
var text = '{"employees":[' +
'{"firstName":"John","lastName":"Doe" },' +
'{"firstName":"Anna","lastName":"Smith" },' +
'{"firstName":"Peter","lastName":"Jones" }]}',
obj = JSON.parse(text);
document.getElementById("demo").innerHTML = obj.employees.map(function (a) {
return a. firstName + ' ' + a.lastName;
}).join(', ');<h2>Create Object from JSON String</h2>
