How it works
The m.parseQueryString
method creates an object from a querystring. It is useful for handling data from URL
javascript
var data = m.parseQueryString('a=hello&b=world');
// data is {a: "hello", b: "world"}
Boolean type casting
This method attempts to cast boolean values if possible. This helps prevents bugs related to loose truthiness and unintended type casts.
javascript
var data = m.parseQueryString('a=true&b=false');
// data is {a: true, b: false}
Leading question mark tolerance
For convenience, the m.parseQueryString
method ignores a leading question mark, if present:
javascript
var data = m.parseQueryString('?a=hello&b=world');
// data is {a: "hello", b: "world"}
Deep data structures
Querystrings that contain bracket notation are correctly parsed into deep data structures
javascript
m.parseQueryString('a[0]=hello&a[1]=world');
// data is {a: ["hello", "world"]}
