<p>There, I did it.<br>
Try not to do it tho, eval is BAD for you. As told above, use Crockford's JSON shim for older browsers (IE7 and under)</p>

<p>This method requires your string to be valid <em>javascript</em>, which will be converted to a javascript object that can then be serialized to JSON.</p>

<p>This will also work</p>
<pre><code>let str = &quot;{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }&quot;

</code></pre>


blocks|key|1588538|text|也许你得试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1588539|str+=+jQuery.parseJSON(str)|code-block|syntax|javascript|1588540|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>Maybe you have to try this:</p>

<pre><code>str = jQuery.parseJSON(str)
</code></pre>


<p>How can I convert a string that describes an object into a JSON string using JavaScript (or jQuery)?</p>

<p>e.g: Convert this (<em>NOT</em> a valid JSON string): 
</p>

<pre><code>var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }"
</code></pre>

<p>into this:</p>

<pre class="lang-js prettyprint-override"><code>str = '{ "hello": "world", "places": ["Africa", "America", "Asia", "Australia"] }'
</code></pre>

<p>I would love to avoid using <code>eval()</code> if possible.</p>


Convert object string to JSON

如何使用JavaScript (或jQuery)将描述对象的字符串转换为JSON字符串？例如:转换此字符串(不是有效的JSON字符串)：var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }"如下所示：str = '{ "hello": "world", "places": ["Africa
