Example Two

The code is as follows

Copy Code

* * $_get[the Address bar get parameter like PHP's ' arg '] function Getargs () { var args = {}; var query = location.search.substring (1); Get query string var pairs = Query.split ("&"); Break at Ampersand for (var i = 0; i < pairs.length; i++) { var pos = pairs[i].indexof (' = '); Look for "Name=value" if (pos = = 1) continue; If not found, skip var argname = pairs[i].substring (0,pos); Extract the name var value = pairs[i].substring (pos+1); Extract the value Value = decodeuricomponent (value); Decode it, if needed Args[argname] = value; Store as a property } return args; Return the object } /* Use method * * * * Url:http://www.111cn.net user=funsion&age=26 * * Alert (Getargs () [' User ']); Output funsion Alert (Getargs () [' Age ']); Output 26
