javascript - 即使在应用了我在网上可以找到的所有方法后，我的页面也没有滚动

标签 javascript html css

当我点击导航栏上的联系人时，我想滚动到页面底部 我努力了 1. windows.scrollTo() 方法 2. windows.scrollBy() 方法 3. element.scrollIntoView(); 4. 以及我能找到的所有其他方法 但页面不滚动。 这是我的 fiddle https://jsfiddle.net/bvuayks8/1/ 我在页面上保留了一些内容，以便可以滚动。 这是代码

// ------------------------------Getting the ids-----------------------------------------
var questionid = document.getElementById('question');
var contact = document.getElementById('contact');

// window.scrollTo(0,2000);


// ------------------------------Clear the browser storage--------------------------------
//localStorage.clear();
//sessionStorage.clear();

questionid.focus();

contact.addEventListener('click', function() {
  window.scrollTo(0, 1500);
  //alert('asdf');

最佳答案

你真的不需要 JavaScript，你可以在页脚中添加一个 id 并简单地在点击联系人按钮时调用它，如下所示。 

body {
  background-image: url(../images/images/documentbackground.jpg);
  background-repeat: no-repeat;
  background-size: cover;
}

/*-------------------------------------Main head------------------------------------------- */

.jumbotron {
  margin: 0;
  background: url(../images/a2.jpg) no-repeat;
}

.mainHead a {
  display: block;
  width: 7%;
  color: white;
  background-color: #3BF44F;
  text-decoration: none;
  transition: background-color .7s;
}

.mainHead a:hover {
  background-color: #08B81B;
}

/*-----------------------------------------------------NavBar--------------------------------------*/

.navbar {}

ul {
  list-style: none;
}

li {
  float: left;
}

.navbar a {
  color: white;
  padding: 0 75px;
  text-decoration: none;
  transition: background-color 0.7s;
}

.navbar a:hover {
  background-color: #0bbc08;
  color: white;
}

/*----------------------------------------------------------Login------------------------------------*/

.login {
  height: 200px;
  background: url(../images/images/back1.jpg);
  background-size: cover;
  background-position: 0 -45%;
  /*transition: all 1s;*/
}

/*.login:hover{
	transition: all 1s;
	background-size: 150%;
}*/

.login h3 {
  text-align: center;
  color: white;
  margin-top: 2%;
}

.login .question {
  position: relative;
  width: 50%;
  margin: 0 auto;
}

.login .question input {
  width: 100%;
}

.login .button {
  position: absolute;
  left: 50%;
}

/*----------------------------------------Menu--------------------------------------------------*/
