如果我做错了什么或者我应该添加什么，请你告诉我吗？非常感谢

Answer 1

在fd-font-dropdown - div中，您应该包含一个<input /> - 元素，该元素将保留value属性中的所选字体。

在changeFont - 函数中，您已经设置了selectedIdx值，所以这应该可以解决问题：

<input type="hidden" name="font" value="{{selectedIdx}}" />

如果您将整个fd-font-dropdown - dev放在表单中，font - 输入的值将随之发送。

所以，它看起来像这样：

<form action="..." method="...">
    <div ng-app="fdApp">
        <div class="font-dropdown" tabindex="1" fd-font-dropdown>
            <input type="hidden" name="font" value="{{selectedIdx}}" />
            <span class="label" ng-style="{{'fontslist[selectedIdx].style'}}">{{fontslist[selectedIdx].name}}</span>
            <ul class="dropdown-list">
                <li ng-repeat="font in fontslist" ng-click="changeFont($index)" ng-class="{'sel': $index == selectedIdx}" ng-style="{{font.style}}">
                    {{font.name}}
                </li>
            </ul>
        </div>
    </div>
    <input type="submit" value="Submit the form" />
</form>

在表单内使用Javascript字体选择
