如何在html面板中查找标题元素并将事件添加到标题以隐藏p标记？

Question

我的JavaScript有问题.我正在尝试编写一个脚本来查找容器内的所有标题元素,并在标题中添加一个click事件来隐藏p标记.

Javascript 
$(function(){
$("dnn_htmlPan1").find(":header").click(function(){
        $("dnn_htmlPan1").find("p").slideToggle("slow");
    });
});

HTML

<div id="dnn_htmlPan1" class="htmlPan">
    <h2>EXPLORE</h2>
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
</div>

Answer 1

你的jQuery选择器错了:

# 用于id:

$("#dnn_htmlPan1").find(":header").click(function(){
        $("#dnn_htmlPan1").find("p").slideToggle("slow");
        // or 
        // $(this).parent().find("p").slideToggle("slow");
        // or 
        // $(this).next().slideToggle("slow");
    });
});

:header 是正确的:

:header 选择

描述:选择所有标题元素,如h1,h2,h3等.
