kendo ui在首次加载时选择一个指定索引/文本

NSS*_*NSS 4 javascript kendo-ui kendo-combobox kendo-dropdown

我遇到的问题是,在第一次加载页面时我想从cookie中读取值,如果找到,我想更改存储在cookie中的主题.不仅想要更改它们,而且我还想在组合框中选择该项目,以便它与应用它们同步.

在构建组合框时,如何在初始页面加载期间选择特定项目?

$(document).ready(function () {

   var initialized = false;
        // theme chooser drop-down
        var cmb=$(".themeChooser").kendoDropDownList({
            dataSource: [
                    { text: "Default" },
                    { text: "BlueOpal" },
                    { text: "Bootstrap" },
                    { text: "Silver" },
                    { text: "Uniform" },
                    { text: "Metro" },
                    { text: "Black" },
                    { text: "MetroBlack" },
                    { text: "HighContrast" },
                    { text: "Moonlight" }
            ],
            dataTextField: "text",
            dataValueField: "value",
            change: function (e) {

                $.cookie('selectedTheme', theme);
                changeTheme(theme);

            }
        });

        theme = ($.cookie('selectedTheme') || "default").toLowerCase();
        //Not sure how to trigger the select of combobox
        cmb.value(theme);  // no effect                       
});

如果没有,请使用:

// selects item if its text is equal to "test" using predicate function
dropdownlist.select(function(dataItem) {
    return dataItem.symbol === "test";
});
