How to build a url with query parameters in Angularjs.
I see the API $location.search()
the problem is $location(url) is to redirect to the url. In my case, I want to pass a url and key:value pairs for the query params and build the url. something like
url: /a/b/c
params: {field1: value1, field2: value2}
result: /a/b/c?field1=value1&field2=value2
I like to use this url for links. I have also seen angular encode ?
, &
characters. Can I avoid this?
My intention was to use the url as href for anchor elements. I do use $http to send the request, but sometimes I need to provide a link, with query params (based on the current object)
Thanks
There is a nice solution as of 1.4+. You can build a query string from a parameters object with $httpParamSerializer
:
var qs = $httpParamSerializer(params);
Default $http params serializer that converts objects to strings according to the following rules:
{'foo': 'bar'} results in foo=bar
{'foo': Date.now()} results in foo=2015-04-01T09%3A50%3A49.262Z (toISOString() and encoded representation of a Date object)
{'foo': ['bar', 'baz']} results in foo=bar&foo=baz (repeated key for each array element)
{'foo': {'bar':'baz'}} results in foo=%7B%22bar%22%3A%22baz%22%7D" (stringified and encoded representation of an object)
Note that serializer will sort the request parameters alphabetically.
