reveal-it.js是一款jQuery文字淡入淡出显示特效插件。该文字特效插件可以使文字从左向右淡入淡出显示。

使用方法

首先要在页面中引入jquery和reveal-it.js和reveal-it.css文件：

<link href="css/reveal-it.css" rel="stylesheet" type="text/css" />                
<script type="text/javascript" src="js/jquery.min.js"></script>
<script src="js/reveal-it.js"></script>

该jquery文字特效共有4种使用方法。

页面加载时立刻显示淡入淡出文字特效
<div class="container">
    <div class="row">
        <div class="col-xs-12">
            <p>Box 1: Reveal Immediately</p>
            <div class="box1">
                <h1>Lorem ipsum dolor sit amet, ne mel vero impetus voluptatibus</h1>
            </div>
        </div>
    </div>
</div>                 
                
jQuery(function () {
    //Box 1: reveal immediately - on page load
    //NOTE: id does refer to an element id, It is used to
    //      uniquely refer to the element to be revealed.
    var options1 = {
        id: 'box1'
    };
    $('.box1').initReveal(options1);
});
在指定延时时间后显示淡入淡出文字特效
<div class="container" style="background-color: #555;">
    <div class="row">
        <div class="col-xs-12">
            <p>Box 2: Reveals after 3000ms delay</p>
            <div class="box2">
                <h1>Lorem ipsum dolor sit amet, ne mel vero impetus voluptatibus</h1>
            </div>
        </div>
    </div>
</div>                  
                
var options2 = {
    id: 'box2'
    , delay: 3000
    , background: '#555'
};
$('.box2').initReveal(options2);
指定事件（如点击事件）来显示淡入淡出文字特效
<div class="container">
    <div class="row">
        <div class="col-xs-12">
            <p>Box 3: Reveal on click event</p>
            <div>
                <div class="box3">
                    <h1>Lorem ipsum dolor sit amet, ne mel vero impetus voluptatibus</h1>
                </div>
            </div>
 
            <button class="btn btn-primary btn-reveal">Reveal!</button>
        </div>
    </div>
</div>                  
                
var options3 = {
    id: 'box3'
    , auto: false
};
var box3 = $('.box3');
box3.initReveal(options3);
 
$('.btn-reveal').on('click', function () {
    box3.performReveal(options3);
});
当元素滚动进入视口时显示淡入淡出文字特效
<div class="container">
    <div class="row">
        <div class="col-xs-12">
            <p>Box 4: Reveal when element scrolls into the viewport</p>
            <div>
                <div class="box4">
                    <h1>Lorem ipsum dolor sit amet, ne mel vero impetus voluptatibus</h1>
                </div>
            </div>
        </div>
    </div>
</div>                  
                
var options4 = {
    id: 'box4'
    , auto: false
    , trigger: 'on-visible'
};
$('.box4').initReveal(options4);
