How it works
The m.parseQueryString
method creates an object from a querystring. It is useful for handling data from URL
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.
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:
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
m.parseQueryString("a[0]=hello&a[1]=world")
// data is {a: ["hello", "world"]}
