onclick =“”javascript内联问题

标签: javascript html onclick

我找到了一个很棒的纯javascript代码,用于平滑滚动功能,但我不知道如何让它在onclick内联函数中工作。 我确定它的东西很简单,但是javascript非常弱......

<div class="navbar">
  <button type="button" id="clickme">scroll whit class</button>
  <button type="button" onclick="smoothScroll(third)" >not working yet</button>
 </div>

<div class="third" id="third">The start of the red section!</div>

和smoothScroll函数javascript:

var targetY;

document.getElementById('clickme').addEventListener('click', function() {

    smoothScroll(document.getElementById('third'));
});

window.smoothScroll = function(target) {

    var scrollContainer = target;

    headerSpace();

    do {
    scrollContainer = scrollContainer.parentNode;
    if (!scrollContainer) return;
    scrollContainer.scrollTop += 1;
    }
    while (scrollContainer.scrollTop == 0);

    do {
    if (target == scrollContainer) break;
    targetY += target.offsetTop;
    }
    while (target = target.offsetParent);

    scroll = function(c, a, b, i) {

        i++; if (i > 30) return;
        c.scrollTop = a + (b - a) / 30 * i;
        setTimeout(function() {scroll(c, a, b, i); }, 20);
    }

    scroll(scrollContainer, scrollContainer.scrollTop, targetY, 0);
}

function headerSpace() {

    var header = document.querySelectorAll('.navbar');
    targetY = -header[0].clientHeight;
}

正如您所看到的,所有已准备好的getElement都是id,但我想将其删除并使其仅使用白色内联

onclick="smoothScroll(second)"
onclick="smoothScroll(third)"
onclick="smoothScroll(fourth)"

等...... 这是jsFiddle

var scrollContainer = document.getElementById(target);
target = document.getElementById(target);

然后在你的HTML中

<button type="button" onclick="smoothScroll('third')" id="clickme">scroll whit onclick=""</button>

尝试使用这个将帮助您顺利滚动,这太容易使用

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
  var target = $(this.hash);
  target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

您需要的只是拥有一个链接

<a href="#third">not working yet</a>
<div id="third"></div>

这将与你绑定到任何div(href(用于链接)和id(对于div))的任何链接顺利地工作)小心这两个属性,这将工作正常

您的小提琴与您的问题中提供的代码不同。假设您的小提琴是最新版本,它不起作用,因为您有两个具有相同ID的按钮,根据HTML规范无效

<button type="button" id="clickme">scroll whit class</button>
<button type="button" id="clickme">scroll whit onclick=""</button>

因此,事件监听器仅添加到第一个按钮,因为getElementById只返回一个元素:

document.getElementById('clickme').addEventListener('click', function() {

您可以通过向第二个按钮添加不同的ID来解决此问题:

<button type="button" id="clickme">scroll whit class</button>
<button type="button" id="clickme1">scroll whit onclick=""</button>

并添加第二个监听器:

function scrollDiv() 
{
    var header = document.querySelectorAll('.navbar');
    aim = -header[0].clientHeight;
    initial = Date.now();

    smoothScroll(document.getElementById('third'));
}

document.getElementById('clickme').addEventListener('click', scrollDiv)
document.getElementById('clickme1').addEventListener('click', scrollDiv)

或者稍微清洁一点,你可以在按钮上添加一个类并迭代结果document.getElementsByClassName
