来自 php 的 json_encode 问题的 JSON.parse

Question

Running an issue with parsing JSON recieved from php backend. On php i have an array, which i send by json_encode:

$result[] = (object) array('src' => "{$mergedFile}", 'thumb_src' => "{$thumb_file}");
echo json_encode($result);

And when trying to JSON.parse it i recieve error:

"Uncaught SyntaxError: Unexpected token F"

The response itself looks this like:

[{"src":"upload\/lessons\/963\/video\/176481500-m.webm","thumb_src":"upload\/lessons\/963\/slide\/thumb_0f515a62753626e1aaefdc7968e8103e.jpg"}]

Very strange thing is that, similar code works nearby.. looks fine.. Appreciate any help, thanks.

Answer 1

You cannot JSON.parse() JSON, the param must be a string :

JSON.parse('[{"src":"upload\/lessons\/963\/video\/176481500-m.webm","thumb_src":"upload\/lessons\/963\/slide\/thumb_0f515a62753626e1aaefdc7968e8103e.jpg"}]');

the error you receive can easily be reproduced by :

JSON.parse([{"src":"upload\/lessons\/963\/video\/176481500-m.webm","thumb_src":"upload\/lessons\/963\/slide\/thumb_0f515a62753626e1aaefdc7968e8103e.jpg"}]);
