JavaScript & jQuery Code Snippet

1. 按照每个object的Name属性对object对象集合进行排序；

            //sort a collection of objects by Name property
            function sortByItemName(originalObjects) {
                var options = {};

                $.each(originalObjects, function (index, item) {
                    options[item.Name] = item;
                });
                //sort() is case sensitive by default
                var keys = Object.keys(options).sort(function (a, b) {
                    return a.toLowerCase().localeCompare(b.toLowerCase());
                });

                //get the results after sort
                var sortedObjects = {};
                $.each(keys, function (i, key) {
                    sortedObjects[i] = options[key];
                });
                return sortedObjects;
            }

2. JavaScript中获取parameter的方法：

function getQueryStrings(){
    var vars = [], hash;
    var q = document.URL.split('?')[1];
    if(q != undefined){
        q = q.split('&');
        for(var i = 0; i < q.length; i++){
            hash = q[i].split('=');
            vars.push(hash[0]);
            vars[hash[0]] = hash[1];
        }
    }
    return vars;
}

另一种方法：

//name参数为需要查询的querystring的key
function getQueryStringRegExp(name) {
        var reg = new RegExp("(^|\?|&)"
+ name + "=([^&]*)(\s|&|$)", "i");
        if (reg.test(location.href))
　　　　　　return unescape(RegExp.$2.replace(/+/g, " "));
        return "";
    }
