纯JS代码实现气泡效果_javascript技巧

关键步骤：

1、引入js文件

<script type="text/javascript" src="js/jquery.min.js?1.1.20">《script》<script type="text/javascript" src='js/jquery.thoughtBubble.js'>《script》

2、在需要使用气泡效果的地方

3、使用气泡效果

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

4、这是jquery.thoughtBubblr.js代码

(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 = "
" + getMainBubble() + getBubbles() + "
";return bubbleContainer;},getMainBubble = function() {return '
' + getText() + '
';},getText = function() {return '' + settings.text + '';},getBubbles = function() {return '
';},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);
