jQuery隐藏和显示div

Question

Hi there not very proficient in coding. 您好，不是很精通编码。 I have #content fading out and in when .background-button clicked. 单击.background-button时，我的#content逐渐淡出。 How do I get text on button to display hide content / show content? 如何在按钮上显示隐藏内容/显示内容？

Also I need to fade out another two divs (.button-next, .button-prev) when hide content clicked? 当隐藏内容单击时，我还需要淡出另外两个div（.button-next，.button-prev）吗？

Anyone that can help? 有人可以帮忙吗？

Answer 1

I would add the event listener using registration instead of an inline event handler: 我将使用注册而不是嵌入式事件处理程序来添加事件侦听器：

var button = document.querySelector('.background-button');
button.addEventListener("click", function(){
    Show('content', this.children[0]);
    return false;
});

The function Show would correspondingly have to be modified to: Show函数将相应地修改为：

function Show(elementid, link) {
    ele = document.getElementById(elementid);
    if (ele.style.display == 'none') {
        ele.style.opacity = 0;
        ele.style.filter = 'alpha(opacity=0)';
        ele.style.display = '';
        valueop = 1;
        setTimeout("fadeIn()", openingdelay);
    }
    else {
        valueop = 9;
        setTimeout("fadeOut()", closingdelay);
    }
    if(link.getAttribute('data-hidden') == "hidden"){
        link.innerHTML = "Click Me To Hide Stuff";
        link.removeAttribute("data-hidden");
    }else{
        link.innerHTML = "Click Me To Reveal More";
        link.setAttribute("data-hidden", "hidden");
    }
}

Answer 2

I modified your html to put and ID to the link: #show_more 我修改了您的HTML，以放置ID和链接ID： #show_more

HTML: HTML：

<div id="content" >Hello! This will remain hidden until the link is clicked.</div>

<div class="background-button"><a id="show_more" href="#">Click Me To Reveal More</a></div>

<div style="background-color:#000; color:#FFF; position:absolute; right:0px; top:100px; height:50px; width:100px;" id="button-next">next</div>
<div style="background-color:#000; color:#FFF; position:absolute; right:0px; top:200px; height:50px; width:100px;" id="button-prev">prev</div>

jQuery: jQuery的：

$('#content, #button-next, #button-prev').hide();
$('#show_more').click(function(e) {
    e.preventDefault(); // disable default <a> behavior

    if ($('#content').is(':visible')) {
        $('#show_more').text('Show Content');
    } else {
        $('#show_more').text('Hide Content');
    }

    $('#content, #button-next, #button-prev').fadeToggle();
});

The first line simply hides the content and buttons. 第一行只是隐藏内容和按钮。 You should hide them via CSS or inline styles and remove this line of code. 您应该通过CSS或内联样式隐藏它们，并删除此行代码。
