Bootstrap Flat UI的select下拉框显示问题解决

bootstrap中文网（http://www.bootcss.com/）里推荐项目有Flat UI（http://www.bootcss.com/p/flat-ui/），非常漂亮，而且少有的竟然具有select下拉框。

我直接打开example（Flat-UI-master/docs/examples/select.html）都是可以的，但是放到我的网站里则不行。

使用chrome调试经过分析，原因是：

$('[data-toggle="select"]').select2();

这行代码读不到，只要引入即可。select2是Flat UI的函数，在flat-ui.js中定义：

    $.fn.select2 = function () {

        var args = Array.prototype.slice.call(arguments, 0),
            opts,
            select2,
            method, value, multiple,
            allowedMethods = ["val", "destroy", "opened", "open", "close", "focus", "isFocused", "container", "dropdown", "onSortStart", "onSortEnd", "enable", "disable", "readonly", "positionDropdown", "data", "search"],
            valueMethods = ["opened", "isFocused", "container", "dropdown"],
            propertyMethods = ["val", "data"],
            methodsMap = { search: "externalSearch" };

        this.each(function () {
            if (args.length === 0 || typeof(args[0]) === "object") {
                opts = args.length === 0 ? {} : $.extend({}, args[0]);
                opts.element = $(this);

                if (opts.element.get(0).tagName.toLowerCase() === "select") {
                    multiple = opts.element.prop("multiple");
                } else {
                    multiple = opts.multiple || false;
                    if ("tags" in opts) {opts.multiple = multiple = true;}
                }

                select2 = multiple ? new window.Select2["class"].multi() : new window.Select2["class"].single();
                select2.init(opts);
            } else if (typeof(args[0]) === "string") {

                if (indexOf(args[0], allowedMethods) < 0) {
                    throw "Unknown method: " + args[0];
                }

                value = undefined;
                select2 = $(this).data("select2");
                if (select2 === undefined) return;

                method=args[0];

                if (method === "container") {
                    value = select2.container;
                } else if (method === "dropdown") {
                    value = select2.dropdown;
                } else {
                    if (methodsMap[method]) method = methodsMap[method];

                    value = select2[method].apply(select2, args.slice(1));
                }
                if (indexOf(args[0], valueMethods) >= 0
                    || (indexOf(args[0], propertyMethods) >= 0 && args.length == 1)) {
                    return false; // abort the iteration, ready to return first matched value
                }
            } else {
                throw "Invalid arguments to select2 plugin: " + args;
            }
        });
        return (value === undefined) ? this : value;
    };

不过ie8还是不行，原因还在核查中。

经过一上午研究，发现flat ui还是不好用，我还得需要花时间解决ie8的问题，但是我的时间并不充裕。看来只能放弃，还是沿用jQuery ui更合适一些。

总结一些flat ui的select使用方法：

    <!-- Loading Bootstrap
    <link href="scripts/Flat-UI-master/dist/css/vendor/bootstrap.min.css" rel="stylesheet">-->

    <!-- Loading Flat UI
    <link href="scripts/Flat-UI-master/dist/css/flat-ui.css" rel="stylesheet">-->

    <!-- HTML5 shim, for IE6-8 support of HTML5 elements. All other JS at the end of file. -->
    <!--[if lt IE 8]>
      <script src="scripts/Flat-UI-master/dist/js/vendor/html5shiv.js"></script>
      <script src="scripts/Flat-UI-master/dist/js/vendor/respond.min.js"></script>
    <![endif]-->

    <select data-toggle="select" class="form-control select select-danger mrs mbm">
        <option value="EVERYDAY">实时</option>
        <option value="BILLING">计费</option>
    </select>

    <!-- jQuery (necessary for Bootstrap's JavaScript plugins)
    <script src="scripts/Flat-UI-master/dist/js/vendor/jquery.min.js"></script>
    <!-- Include all compiled plugins (below), or include individual files as needed
    <script src="scripts/Flat-UI-master/dist/js/flat-ui.js"></script>
    <script>$('[data-toggle="select"]').select2();</script>

注意：

1、必须先引入了bootstrap，再引入flat ui；

2、[if lt IE 8]原来官方是[if lt IE 9]，我用ie8会保错，需要改为8，否则会报错Flat-UI-master/dist/js/vendor/respond.min.js拒绝访问；

3、这种样式是select.html里的样式，和我上面的截图有点差别；
