JSON.parse使用php的json_encode方法产生语法错误

Question

I have a variable $data['tree'], that gets a row array from the database using a method, get_tree($id), from the model.

In my view's js I using

var dbTree = JSON.parse(<?php echo $tree; ?>);

When I load the page I get UncaughtSyntax Error: Unexpected token o in chrome and in firefox I get Syntax Error: Unexpected character.

So When I inspected the script element with chrome the js looked like

var dbTree = JSON.parse({"id":"2","name":"sean","userId":"51fbd3f3a8f2ba1b5b000002","accountId":"51fbd3fca8f2ba1b5b000003","createdAt":"2013-08-02 16:09:34","numRuns":null,"contactExport":"","updatedAt":"2013-08-02 20:15:14","deployed":"1","template":"0","conversation_type":"Conversation"});

I don't see anything wrong with that can some help me out.

Answer 1

JSON.parse should be used with strings, not objects.

Or you even don't need to do anything. It is already an object.

Just like...

var dbTree = <?php echo $tree; ?>;
