The Affix plugin allows a
If you want to reference the plugin's functionality individually, then you need to reference affix.js.
1. Usage
Affix plugin can be used via data attribute or via JavaScript.
1. Through the data attribute: If you need to add additional navigation (Affix) behavior to an element, you only need to add data-spy="affix" to the element that needs to be monitored. Use offsets to define when to toggle the lock and move of an element.
2. Through JavaScript: You can manually add additional navigation (Affix) to an element through JavaScript
2. Positioning through CSS
In both of the above ways of using the Affix plugin, you have to position the content via CSS. The Attached Navigation (Affix) plug-in switches between three classes, each of which presents a specific state: .affix, .affix-top and .affix-bottom. Please follow the steps below to set your own CSS for these three states (without relying on this plugin).
1. At the beginning, the plugin adds .affix-top to indicate the element is at its top position. No CSS positioning is required at this time.
2. When scrolling past an element with additional navigation (Affix) added, the actual additional navigation (Affix) should be triggered. At this time, .affix will replace .affix-top and set position: fixed; (provided by Bootstrap's CSS code).
3. If the bottom offset is defined, when the scroll reaches this position, .affix should be replaced with .affix-bottom. Since the offset is optional, setting it requires that the appropriate CSS be set as well. In this case, add position: absolute; where necessary.
3. Options
Some options are passed via data attributes or JavaScript. The options are listed in the table below:
4. Examples
Additional navigation is pasted somewhere on the screen to implement the anchor function.
1. Basic examples
<body data-spy="scroll" data-target="#myScrollspy"> <div class="container"> <div class="jumbotron" style="height:150px"> <h1>Bootstrap Affix</h1> </div> <div class="row"> <div class="col-xs-3" id="myScrollspy"> <ul class="nav nav-pills nav-stacked" data-spy="affix"data-offset-top="150"> <li class="active"> <a href="#section-1">第一部分 </a> </li> <li> <a href="#section-2">第二部分</a> </li> <li> <a href="#section-3">第三部分</a> </li> <li> <a href="#section-4">第四部分</a> </li> <li> <a href="#section-4">第五部分</a> </li> </ul> </div> <div class="col-xs-9"> <h2 id="section-1">第一部分</h2> <p> ... </p> <h2 id="section-2">第二部分</h2> <p> ... </p> <h2 id="section-3">第三部分</h2> <p> ... </p> <h2 id="section-4">第四部分</h2> <p> ... </p> <h2 id="section-5">第四部分</h2> <p> ... </p> </div> </div> </div>
2. CSS part of navigation
ul.nav-pills {
width: 200px;
}
ul.nav-pills.affix {
top: 30px;
}
//JavaScript 代替 data-spy="affix" data-offset-top="125"
$('#myAffix').affix({
offset : {
top : 150
}
})
We use top by default, but of course it can also be bottom by default. This positioning method is positioned directly through CSS.
//设置成 bottom
ul.nav-tabs.affix-bottom {
bottom: 30px;
}
//设置成 bottom
$('#myAffix').affix({
offset : {
bottom : 150
}
})
Affix contains several events, as follows:
//其他雷同
$('#myAffix').on('affixed-top.bs.affix', function() {
alert('触发！');
});

What is 'this' in JavaScript?
Mar 04, 2025 am 01:15 AM
Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
