jQuery ajax在GBK编码下的解决方案

localParam.js

(function ($) {
    // 根据当前页面编码进行URL编码
    $.urlEncode = function(s) {
        var a, u;
        a = document.createElement('a');
        a.href = '/?_=' + s;
        u = a.href.slice(a.href.indexOf('/?_=') + 4);
        return encodeURIComponent(u).replace(/%25([0-9A-F]{2})/gi, '%$1');
    };
    // 添加 localParam 方法 URL编码使用 $.urlEncode
    $.localParam = function(a) {
        var prefix,
        s = [],
        add = function(key, value) {
            value = $.isFunction(value) ? value() : (value == null ? '' : value);
            s[s.length] = $.urlEncode(key) + '=' + $.urlEncode(value);
        },
        buildParams = function(prefix, obj) {
            var name;
            if ($.isArray(obj)) {
                $.each(obj, function(i, v) {
                    buildParams(prefix + '[' + (typeof v === 'object' ? i : '') + ']', v);
                });
            } else if ($.type(obj) === 'object') {
                for (name in obj) {
                    buildParams(prefix + '[' + name + ']', obj[name]);
                }
            } else {
                add(prefix, obj);
            }
        };

        if ($.isArray(a) || (a.jquery && !$.isPlainObject(a))) {
            $.each(a, function() {
                add(this.name, this.value);
            });
        } else {
            for (prefix in a) {
                buildParams(prefix, a[prefix], add);
            }
        }
        return s.join('&').replace(/%20/g, '+');
    };
} (jQuery));

$.ajax({
    type: 'POST',
    url: '/path/ajax.php',
    dataType: dataType,
    data: $.localParam(data),
});

$.post('/path/ajax.php', $.localParam(data), function (s) {
    // do something
});

$(selector).load('/path/ajax.php #selector', $.localParam(data), function (s) {
    // do something
});

$.localParam($(selector).serializeArray());
