<h2>Create Object from JSON String</h2>
<p>
First Name: <span id="fname"></span><br>
Last Name: <span id="lname"></span><br>
</p>
<script>
var txt = '{"employees":[' +
'{"firstName":"John","lastName":"Doe" },' +
'{"firstName":"Anna","lastName":"Smith" },' +
'{"firstName":"Peter","lastName":"Jones" }]}';
var obj = eval ("(" + txt + ")");
document.getElementById("fname").innerHTML=obj.employees[1].firstName
document.getElementById("lname").innerHTML=obj.employees[1].lastName
</script>
</body>
</html>
问题：
我想看一下txt, 或obj里面的内容，有没有什么语句可以输出，像php里面的var_dump
