Update select.blade.php

[CantonBolo]

添加钩子，使开发者能给指定的select控件进行个性化配置

例如：在grid方法中注入代码：

admin_inject_section('admin.select-ajax.pk_project', "console.log(configs);configs = $.extend(configs, {escapeMarkup: function(e){return e}, templateSelection: function(t){return void 0!==t.description?t.text+'  <span class=\"text-gray\">'+t.description+'</span>':t.text}})");

在页面上能在实例化之前随意配置config变量：

(function () {var configs = {"allowClear":true,"placeholder":{"id":"","text":"\u9009\u62e9"}};

    console.log(configs);configs = $.extend(configs, {escapeMarkup: function(e){return e}, templateSelection: function(t){return void 0!==t.description?t.text+'  <span class="text-gray">'+t.description+'':t.text}})

        $.ajax({"url":"http:\/\/127.0.0.1:8000\/admin\/fdc\/api\/project\/get_projects"}).done(function(data) {
        $(".pk_project").select2($.extend(configs, {
            data: data,
        })).val([]).trigger("change");
    });
})();;
