js氣泡效果，在項(xiàng)目需求中經(jīng)常遇到。今天小編把大概實(shí)現(xiàn)步驟分享到腳本之家平臺(tái)，感興趣的朋友可以參考下

就不給大家多文字說明了。給大家梳理下關(guān)鍵步驟。

關(guān)鍵步驟：

1、引入js文件

<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src='js/jquery.thoughtBubble.js'></script>

2、在需要使用氣泡效果的地方

<div id='mainContainer' class='container'>
<img src='ahout.JPG' id="thoughtBubble" alt='whats up?' />
</div>

3、使用氣泡效果

<script type="text/javascript">
$(window).ready( function() {
$('#thoughtBubble').thoughtBubble({
text: 'baby,I love you',
font: 'avenir'
});
});

4、這是jquery.thoughtBubblr.js代碼

(function($) {
$.fn.thoughtBubble = function( defaults ) {
var settings = $.extend({
backgroundColor: 'white',
fontColor: 'black',
width: '330px',
height: '210px',
fontSize: '15px',
bubbleColor: 'white',
speed: 125
}, defaults ),
getBubbleDiv = function( container ) {
var offset = container.offset(),
modifiedHeight = offset.top - parseInt( settings.height ),
style = '"position: absolute; top:' + modifiedHeight + 'px; left:' + offset.left + 'px ; width:' + settings.width + '; height:' + settings.height + ';"',
bubbleContainer = "<div class='bubble-holder' style=" + style + ">" + getMainBubble() + getBubbles() + "</div>";
return bubbleContainer;
},
getMainBubble = function() {
return '<div class="main-bubble-holder"><div class="bubble main-bubble">' + getText() + '</div></div>';
},
getText = function() {
return '<span style="vertical-align: middle; color: ' + settings.fontColor + ';font-size: ' + settings.fontSize + '; font-family: ' + settings.font + '">' + settings.text + '</span>';
},
getBubbles = function() {
return '<div class="sm-bubble-holder"><div class="bubble bubbleLg"></div><div class="bubble bubbleMd"></div><div class="bubble bubbleSm"></div></div>';
},
animate = function(){
var bubbles = $(document).find('.bubble'),
reversed = bubbles.get().reverse(),
speed = settings.speed;
$(reversed[0]).stop().animate({ opacity: 1}, speed, function() {
$(reversed[1]).animate({ opacity: 1}, speed, function() {
$(reversed[2]).animate({ opacity: 1}, speed, function() {
$(reversed[3]).animate({ opacity: 1},speed);
});
});
});
},
unanimate = function() {
var bubbles = $(document).find('.bubble');
bubbles.stop().animate({opacity: 0});
},
shiftDiv = function( container ) {
var bubbleHolder = $(document).find('.bubble-holder'),
previousPosition = container.offset().left;
bubbleHolder.css('left', previousPosition);
};
return this.each( function() {
var $this = $(this),
container = getBubbleDiv( $this );
$this.on('mouseenter', animate );
$this.on('mouseout', unanimate );
$(window).on('resize', shiftDiv.bind(this, $this) );
return $this.parent().prepend(container);
});
};
})(jQuery);

以上給大家分享了js氣泡效果的關(guān)鍵步驟，代碼簡單易懂，就沒給寫過多的文字說明，大家有疑問歡迎給我留言，小編會(huì)及時(shí)回復(fù)大家的，在此小編也非常感謝大家對(duì)腳本之家網(wǎng)站的支持！
