javascript - 点击隐藏div信息 [英] javascript - Hide div info on click

问题描述

我有一个滑块产品列表，分为3类。单击产品时，将显示产品说明。单击新产品时，将隐藏旧产品说明并显示新产品说明。

I have a list of products in a slider broken into 3 categories. When you click on a product, the product description appears. When you click on a new product, the old product description hides and the new product description appears.

我的问题是当您更改我希望前面的描述关闭的类别时，因此在您单击新产品之前不会显示任何描述。目前，在点击新产品之前，产品描述仍显示最后一个产品的最后一个产品。

My problem is when you change the categories I want the previous description to close and so that no descriptions are shown until you click a new product. Currently the product description is still showing of the last product from the last category until a new product is clicked.

我试图为此部分编写javascript但失败了。有人可以帮忙吗？

I tried to write the javascript for this portion but failed. Can anyone help?

javascript（前10行是工作代码）：

The javascript (the first 10 lines are the working code):

function product(x) {
  document.querySelectorAll('.hidden').forEach(function(el){
    el.style.display = "none";
  });
  if (x.style.display === "block") {
    x.style.display = "none";
  } else {
    x.style.display = "block";
  }
}

var anav = document.querySelector('#navsliderselector');
var divprod = document.querySelector('.hidden');
button.addEventListener('click', function (event) {
      if (menu.style.display == "") {
          menu.style.display = "none";

      } else {
          menu.style.display = "";

      }
    }
  );

这是HTML：

<ul>
                <li><button onclick="product(product1info)"><h4>Knee Brace L1843</h4></button></li>
                <li><button onclick="product(product2info)"><h4>Wrist Brace L3807</h4></button></li>
                <li><button onclick="product(product3info)"><h4>Wrist Brace</h4></button></li>
                <li><button onclick="product(product4info)"><h4>Ankle Brace L1005</h4></button></li>
                <li><button onclick="product(product5info)"><h4>Back Brace L0650</h4></button></li>
              </ul>

              <ul>
                <li><button onclick="product(product6info)"><h4>Back Brace L0650</h4></button></li>
              </ul>
               <ul>
                <li><button onclick="product(product7info)"><h4>Back Brace L0650</h4></button></li>
              </ul>

    <nav>
                <a href="#" id="navsliderselector">Braces</a>
                <a href="#" id="navsliderselector">Mobility</a>
                <a href="#" id="navsliderselector">Incontinence</a>
              </nav>

              <div id="product1info" class="hidden">
                    <h2>Knee Brace L1843</h2>
                    <p>Product Info</p>
                </div>

                <div id="product2info" class="hidden">
                    <h2>Wrist Brace L3807</h2>
                    <p>Product Info</p>
                </div>

                <div id="product3info" class="hidden">
                    <h2>Wrist Brace</h2>
                    <p>Product Info</p>
                </div>

                <div id="product4info" class="hidden">
                    <h2>Ankle Brace L1005</h2>
                    <p>Product Info</p>
                </div>

                <div id="product5info" class="hidden">
                    <h2>Back Brace L0650</h2>
                    <p>Product Info</p>
                </div>

推荐答案

我相信您正在为所有人编写产品功能onclicks错误。

I believe you are writing the product function for all your onclicks wrong.

您使用函数名称中包含的数字编写所有onclick函数：

You write all your onclick functions with the number included in the function name:

<li><button onclick="product1()"><h4>Knee Brace L1843</h4></button></li>

根据您给定的代码，没有其他带有数字的产品功能，这就是问题所在。

Based on your given code there are no other product functions with numbers with them so that is the problem.

由于你的产品函数采用参数x并修改了它的显示，我认为你应该将元素本身传递给参数

Since your product function takes a parameter x and modifies the display of it, I think you should be passing in the element itself into the parameter

所以不是这样：

<li><button onclick="product1()"><h4>Knee Brace L1843</h4></button></li>

你应该这样写：

<li><button onclick="product(this)"><h4>Knee Brace L1843</h4></button></li>

编辑：

对不起，我似乎误解了这个问题。如果您的目的是在每次客户选择新产品类别时清除所有产品描述，那么：

Sorry, I seem to have misunderstood the question. If your purpose was to clear all product descriptions every time the client chooses a new product category then:

您可以简单地创建一个新的onclick函数来清除所有描述（I'我将使用您为产品功能执行的实现）：

You can simply create a new onclick function that clears all descriptions(I'm going to use the implementation you did for your product function):

function clearAllDescriptions(){
  document.querySelectorAll('.hidden').forEach(function(el){
    el.style.display = "none";
  });
}

然后将其分配到导航类别：

and then assign it to the navigation categories:

<a href="#" onclick="clearAllDescriptions()" id="navsliderselector">Braces</a>
<a href="#" onclick="clearAllDescriptions()" id="navsliderselector">Mobility</a>
<a href="#" onclick="clearAllDescriptions()" id="navsliderselector">Incontinence</a>
