sunliwen / getQueryParam.js
Created September 22, 2013 12:27
Found this useful snippet in http://getbootstrap.com/customize/
function getQueryParam(key) {
key = key.replace(/[*+?^$.\[\]{}()|\\\/]/g, "\\$&"); // escape RegEx meta chars
var match = location.search.match(new RegExp("[?&]"+key+"=([^&]+)(&|$)"));
return match && decodeURIComponent(match[1].replace(/\+/g, " "));
}
// ?id=123
// getQueryParam('id') --> 123

how to make south aware of custom field
"""
Following error will occur if there's custom field.
```
! Cannot freeze field 'myapp.mymodel.entity_type'
! (this field has class myapp.fields.EntityTypeField)
! South cannot introspect some fields; this is probably because they are custom
! fields. If they worked in 0.6 or below, this is because we have removed the
! models parser (it often broke things).
