Javascript fails to read this json string as it contains a single quote character which it sees as the end of the string.

How can I escape the single quote so that it is not seen as the end of the string?

var json = '{"1440167924916":{"id":1440167924916,"type":"text","content":"It's a test!"}}';

var parsed = JSON.parse(json);

回答1:

Use a backslash to escape the character:

var json = '{"1440167924916":{"id":1440167924916,"type":"text","content":"It\'s a test!"}}';
var parsed = JSON.parse(json);

Just escape the single quote with a backslash such as \':

var json = '{"1440167924916":{"id":1440167924916,"type":"text","content":"It\'s a test!"}}';

var parsed = JSON.parse(json);

//Output parsed to the document using JSON.stringify so it's human-readable and not just "[object Object]":
document.write(JSON.stringify(parsed));
