JSON htmlentities javascript
javascript, json, special-characters, string
Solution
Even when sending stuff via POST, you still need to correctly urlencode. If the ampersand character is in the JSON body, this would be treated as a parameter/value pair separator and your JSON would no longer be valid.
`escape()` is deprecated so use `encodeURIComponent()`. It shouldn't be overkill as this is one of the intended purposes of the function.
Problem
I am using an XMLHttpRequest to POST a JSON string to PHP. The JSON object is created in JavaScript and using the JSON2.js from json.org to create an JSON string representing the object. `JSON.stringify(object);` Whenever the object contains a string which has a special character in it, e.g. é, JavaScript does not give any error but PHP receives an empty array `[]` Is there a JavaScript function which produces the exact same resutls as the PHP function `htmlentities()` The data is send via POST, so the following functions ``` escape() encodeURI() encodeURIComponent() ``` are a bit overkill. Thanks!
