Question

我有一个免责声明div，我想在点击某个菜单项时显示。我让我的Jquery用这个脚本正确显示我隐藏的div： $(function(){ var $allItems = $(".food-container > div"); $(document.body).on("click", "a.menu-item", function () { var id = this.id, itemId = ".food-container > #item-" + id; $allItems.not($(itemId).fadeToggle()).hide(); }); }); 我正在使用高级自定义字段转发器字段，因此我需要将字段隐藏在Repeater循环之外。我拥有的菜单ID是＆＃34; 4＆＃34;。所以我只需要连接免责声明div，即＆＃34; burger-disclaimer＆＃34; ＃4点击事件。

这应该让你走上正确的道路。我正在抓取click事件的ID（evt变量），以查看所选内容。

HTML：

<a id="1" href="javascript:void(0)" class="menu-item">Appetizers<i class="fa fa-caret-right"></i></a>
<a id="2" href="javascript:void(0)" class="menu-item">Tex-Mex<i class="fa fa-caret-right"></i></a>
<a id="3" href="javascript:void(0)" class="menu-item">Salads<i class="fa fa-caret-right"></i></a>
<a id="4" href="javascript:void(0)" class="menu-item">Burgers<i class="fa fa-caret-right"></i></a>
<div class="food-container">
    <div id="item-1" style="display: none;">
        <div class="food">
            <h3>Mac N Cheese Bites</h3> Breaded, then fried macaroni, stuffed with cheese</div>
        <div class="price"> $8 </div>
    </div>
    <div id="item-2" style="display: none;">
        <div class="food">
            <h3>Salads</h3> Salads
        </div>
        <div class="price"> $8 </div>
    </div>
    <div id="item-3" style="display: none;">
        <div class="food">
            <h3>Tex-Mex</h3> Tex-Mex
        </div>
        <div class="price"> $8 </div>
    </div>
    <div id="item-4" style="display: none;">
        <div class="food">
            <h3>Burgers</h3> Burger
        </div>
        <div class="price"> $8 </div>
    </div>
</div>
<div class="burger-disclaimer">
    *All sandwiches and burgers are served with fries or potato chips. Side salad and onion rings available as side, add $2 upcharge
</div>

JS：

$(function() {
    var $allItems = $(".food-container > div");
    $(document.body).on("click", "a.menu-item", function(evt) {
        var id = this.id,
            itemId = ".food-container > #item-" + id;
        $allItems.not($(itemId).fadeToggle()).hide();
        if (evt.target.id == 4) {
            $('.burger-disclaimer').toggle();
        } else {
            $('.burger-disclaimer').hide();
        }
    });
});
