在Javascript

Question

我有3个服务面板div我使用javascript来显示它们被点击后＃39;。

我发布了一个jsFiddle来显示面板的全部内容。

• 确保jsFiddle在Javascript上（没有包装 - ）以使函数正常工作

我想弄清楚一种方法来编写一个打开每个面板及其内部内容的函数。 这将消除我为每个面板创建一个新功能和#id。

<!-- Panel 1 -->
<div class="service-panel" onclick="openService()">

<!-- Panel 2 -->
<div class="service-panel" onclick="openService2()">

<!-- Panel 3 -->
<div class="service-panel" onclick="openService3()">


function openService() {
var x = document.getElementById('open1');
var y = document.getElementById('toggle1');
if (x.style.display === 'none') {
    x.style.display = 'block';
    y.innerHTML = '-';
} else {
    x.style.display = 'none';
    y.innerHTML = '+';
    y.style.color = '#ffffff';
    }
}

function openService2() {
var x = document.getElementById('open2');
var y = document.getElementById('toggle2');
if (x.style.display === 'none') {
    x.style.display = 'block';
    y.innerHTML = '-';
} else {
    x.style.display = 'none';
    y.innerHTML = '+';
    y.style.color = '#ffffff';
    }
}

必须有一个简单的解决方案来解决这个问题。

这是使用jQuery的解决方案：

$(function() {
  $(".open").hide();
  $(".service-panel").click(function() {
    $(this).next().toggle();
    $(this).data("open", !$(this).data("open"));
    $(this).find(".toggle").html($(this).data("open") ? "-" : "+");
  });
});

.section-service {
  display: block;
  position: relative;
  width: 100%;
  height: 100%;
  z-index: 3;
}

.container-service {
  margin: 0 auto;
  display: block;
  width: 100%;
  max-width: 1400px;
  height: 100%;
}

.service-panel {
  margin: 0 auto;
  display: block;
  width: 90%;
  height: 50px;
  background-color: #636363;
  margin-bottom: 1px;
  cursor: pointer;
}

.service-panel:hover {
  background-color: #545454;
}

.service-panel-open {
  margin: 0 auto;
  padding: 30px 0px;
