JS正则备忘

匹配所有：

var query = location.href.substr(location.href.indexOf('?') + 1);
//    console.log(query);
var patt = new RegExp('([^=]*)=([^&#]*)', 'g');
var result;
while((result = patt.exec(query)) != null) {
    if(result[1].substr(0, 1) == '&') {
        params[result[1].substr(1)] = result[2];
    } else {
        params[result[1]] = result[2];
    }
}
