jQuery-在脚本标签中解析JSON

Question

I tried to parse JSON string inside a script tag <script src='//remotehost/test.js'>{'1':'2'}</script>

dom = document.scripts[document.scripts.length - 1]; //it gets the correct tag, checked
d = $.parseJSON($(dom).html());

But I get SyntaxError: JSON.parse: expected property name or '}' at line 1 column 2 of the JSON data error. I checked http://api.jquery.com/jquery.parsejson/ and the result of $(dom).html() is listed as one of malformatted JSON string result. How do I parse the JSON using jQuery?

Answer 1

The issue is that it's not valid JSON. Valid JSON uses double quotes.

Change your HTML to:

<script src='//remotehost/test.js'>{"1":"2"}</script>

Answer 2

{'1':'2'} is a JavaScript Object, not a correct JSON.

JSON format of Object is a String use Double quotation marks, like: '{"1": "2"}'
