javascript - jQuery cookie : How can I save the color selection of the user for the next visit?

Question

我正在开发一个 jQuery 预定义颜色选择器。当用户单击颜色选择器的一种颜色时，我想保存颜色选择:http://prntscr.com/7rnafa 。为了与 cookies 交互，我使用了 jQuery 插件 https://github.com/carhartl/jquery-cookie .

jQuery 代码:

var color_elements_background = ".nodeList .categoryStrip, .breadcrumb";

var color_elements_text = "a:link, a:visited";

$(".colorPicker span").on("click", function()
{
    var customColor = $(this).attr("custom_color");
    $(color_elements_background).css("background-color", customColor);
    $(color_elements_text).css("color", customColor);
});
});

我的颜色选择器的 HTML:

                <div class="colorPicker">
                    <div class="colorPickerContent">
                        <div class="colorPickerItems">
                            <li>
                                <span custom_color="#FF0000">Color 1</span>
                            </li>
                            <li>
                                <span custom_color="#333333">Color 2</span>
                            </li>
                            <li>
                                <span custom_color="#FFFFFF">Color 3</span>
                            </li>
                            <li>
                                <span custom_color="#D0D0D0">Color 4</span>
                            </li>
                            <li>
                                <span custom_color="#CCCCCC">Color 5</span>
                            </li>
                        </div>
                    </div>
                </div>

查看插件:

https://github.com/js-cookie/js-cookie

要使用 Javascript 库 js.cookie 保存 cookie，您可以使用:

Cookies.set("color", customColor);

还可以从保存的 cookie 中获取值:

var customColor = Cookies.get("color");

如果您想删除该 cookie，您可以使用:

Cookies.remove("color");
