将输入字符串转换为GET变量

I'm trying to create an ajax search page, which shows live results similar to google.

Right now I am struggling with how to convert a search query such as small dog to a GET parameter, in this case it would be "searchresults?search=small+dog". The thing I want is to replace all white space between words to + and to remove whitespaces before and after words.

I think it's possible with regex, or is there some javascript or jquery function to encode that?

I tried using escape, encodeURI, ... , but it made whitespace %20. Will PHP understand that they are multiple words?

    To manually escape a query component in Javascript, simply use encodeURIComponent:

    var url = '/searchresults?seach=' + encodeURIComponent(query);
    

    To trim the query string before, use .trim() on the string.
