Question

我有一行需要根据变量显示/隐藏，如下所示： -

{{#if ShowCamValue == true}}
        <div class="row">
            <div class="cell">
                CAM (SF)
            </div>
            {{#each Properties}}
            <div class="cell">
                {{Property.Cam}}
            </div>
            {{/each}}
        </div>
 {{/if}}

即使这是真的（即ShowCamValue等于“true”），它仍然不显示该行。任何想法发生了什么。

而非{{#if ShowCamValue}}在车把中无效。

并检查每个帮助器语法，您还没有定义==。你可以使用Property

this

车把js如果不工作
