缺少Knockoutjs SyntaxError:属性id之后

Question

我正在尝试使用attr绑定来设置属性(data-rating),但我收到错误消息:

错误:无法解析绑定.消息:SyntaxError:missing:属性id之后; 绑定值:attr:{data-rating:UserMovies [0] .Rating}

attr绑定是否不接受带连字符的属性？

<ul class="content thumbnails" data-bind="foreach: movies, loader: $root.isLoading">
    <li class="movie">
        <div class="image">
            <img data-bind="image: { src: Poster.Detailed, alt: Title }" />
            <div class="actions">
                <!-- ko if: UserMovies.length > 0 -->
                <span class="raty" data-bind="attr: { data-rating: UserMovies[0].Rating }"></span>
                <!-- /ko -->
            </div>
        </div>
    </li>
</ul>

Answer 1

您应该使用a包装属性名称quote,如果UserMovies是observableArray,则应使用()以下内容将其解包:

<span class="raty" data-bind="attr: { 'data-rating': UserMovies()[0].Rating }"></span>
