jquery - build pretty url from parameters

jQuery has a param() function, I'm looking for similar functionality. I need to return a url in my object. For example:

url: function() {
  return this.baseUrl + '?' + $.param({page: this.page, perPage: this.perPage});
},

this will return a url in the form of example.com/?page=1&perPage=5 or something similar. How can I form the url example.com/page/1/perpage开发者_如何转开发/5?

You can create your own function:

function build(base, params) {
    for(var k in params) {
        if(params.hasOwnProperty(k)) {
            base += '/' + k + '/' + params[k];
        }
    }
    return base;
}

The only problem is that the order of the parameters is not guaranteed (which is not a problem for query strings but might be for this kind of URLs). You might also want to add a check if base already ends with a slash or not.

Just an idea :)

'example.com/?page=1&perPage=5'.replace(/[&=]/g,'/').replace('?','')
 .toLowerCase();

tack this on the end:

replace(/[&=]/g,'/').replace('?','')

like so:

url: function() {
  return (this.baseUrl + '?' + $.param({page: this.page, perPage: this.perPage})).replace(/[&=]/g,'/').replace('?','');
},

edited to point out in re to Felix Kling's concern about ?'s: This will only remove the FIRST ? leaving any other ?'s that are part of the query string INTACT. Perfectly safe to use.
