javascript - 单击图像显示/隐藏多个 div

标签 javascript jquery html

我是编码新手，所以请多多包涵。我查看了针对同一问题发布的一些回答，并在一些已解决的 jsfiddle 链接中输入我的信息时让代码正常工作。

问题是:当我将工作代码插入我的 HTML 和 JS 文件时，它似乎不起作用。我查看了我的代码，但不确定是什么破坏了它或为什么它没有显示。我想知道是否有人可以查看我的代码并告诉我原因？

我所说的部分是浏览菜单和菜单输出部分。基本上，如果您在浏览菜单导航中单击图像(杂食、素食、健康)，将显示相应的菜单输出。

我还在这篇文章中包含了我的 HTML 和 JS。样式和间距现在有点困惑，因为我一直在修补我的标记中的东西。我最近还读到表格不好，所以我将在我的 html 中将其更改为无序列表。

非常感谢!

JavaScript:

// Scrolling Function
$('a').click(function(){
    $('html, body').animate({
        scrollTop: $( $(this).attr('href') ).offset().top
    }, 500);
    return false;
});

// Load All Images
$('body').waitForImages({
    waitForAll: true,
    finished: function() {
       // All images have loaded.
    }  
});


//Hide All Divs
$("#output > div").hide();

$(".dietchoice a").click(function(e) {
  $("#output div").hide();
  $(this.hash).show();
  e.preventDefault();
});
$("#areas div:not(#meat)").hide();

最佳答案

代替

$(this.hash).show();

你可能应该使用

$(this.attr('href')).show();

this.hash 可能返回 undefined 因为属性 hash 不存在。

如果我的解决方案抛出类似“undefined method attr()”的错误，您可能需要使用 jQuery 选择器。

$($(this).attr('href')).show();

我建议使用控制台对象进行调试。您可以在 Mozilla Developer Network 上找到一些关于调试的文档。 .

此选择器 $("#output > div") 与此选择器 $("#output div") 不同。根据您的 HTML，两个选择器返回相同的元素，但如果您要更改 HTML 结构，则可能会出现问题。
