[英]Sliding Side Nav Bar
I need help with making a vertical nav bar that slides to the right to reveal more content.我需要帮助制作向右滑动以显示更多内容的垂直导航栏。 I'm aiming towards something similar to the blue bar here: http://www.teehanlax.com/labs/ .我的目标是类似于此处的蓝色条: http ://www.teehanlax.com/labs/。 The nav bar slides out (to the right) when the side navigation bar is clicked, and slides back (to the left) when the x
button is clicked.单击侧面导航栏时,导航栏滑出(向右),单击x
按钮时,导航栏滑回(向左)。
my code is:我的代码是:
<!--Am I implementing the jQuery right?-->
<!DOCTYPE HTML> <html> <head> <title>Nishad</title>
<link rel="stylesheet" href="style.css">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"> </script>
$(function() { $('#nav').click(function()
{ var leftMargin = ($(this).css('margin-left') === '0px') ? '-150px' : '0px'; $(this).animate({ 'margin-left' : leftMargin }, 500);
});
});
</head> <body> <div id="wrapper">
<div id="nav"></div>
<div id="content"></div>
</div> </body> </html>
If you inspect the element, you can see that the website is making use of a negative value for the navigation's margin-left
.如果您检查该元素,您可以看到该网站正在为导航的margin-left
使用负值。 When you click the +
, they are setting margin-left
to 0px
.当您单击+
时,他们将margin-left
设置为0px
。
You can get the click effect by attaching a click event handler.您可以通过附加点击事件处理程序来获得点击效果。 The sliding effect can be done using jQuery's animate()
.滑动效果可以使用 jQuery 的animate()
来完成。 Below is an example what I just mentioned.下面是我刚才提到的一个例子。
$(function() { $('#nav').click(function() { var leftMargin = ($(this).css('margin-left') === '0px')? '-150px': '0px'; $(this).animate({ 'margin-left': leftMargin }, 500); }); });
#wrapper { white-space: nowrap; } #nav, #content { height: 500px; display: inline-block; } #nav { width: 200px; margin-left: -150px; cursor: pointer; background: lightgreen; } #content { width: 500px; background: lightblue; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="wrapper"> <div id="nav"></div><div id="content"></div> </div>
