本文實例講述了javascript實現動態統計圖的代碼。分享給大家供大家參考。具體如下:
運行效果截圖如下:

具體代碼如下
html代碼:
<div id="content"> <div class="legend"> <h1>汽車銷量:</h1> <div class="skills"> <ul> <li class="jq">大眾</li> <li class="css">豐田</li> <li class="html">別克</li> <li class="php">福特</li> <li class="sql">長安</li> </ul> </div> </div> <div id="diagram"></div> </div> <div class="get"> <div class="arc"> <span class="text">大眾</span> <input type="hidden" class="percent" value="95" /> <input type="hidden" class="color" value="#97BE0D" /> </div> <div class="arc"> <span class="text">豐田</span> <input type="hidden" class="percent" value="90" /> <input type="hidden" class="color" value="#D84F5F" /> </div> <div class="arc"> <span class="text">別克</span> <input type="hidden" class="percent" value="80" /> <input type="hidden" class="color" value="#88B8E6" /> </div> <div class="arc"> <span class="text">福特</span> <input type="hidden" class="percent" value="53" /> <input type="hidden" class="color" value="#BEDBE9" /> </div> <div class="arc"> <span class="text">長安</span> <input type="hidden" class="percent" value="45" /> <input type="hidden" class="color" value="#EDEBEE" /> </div> </div>
css代碼:
#content {position:absolute;top:50%;left:50%;margin:-340px 0 0 -450px;width:900px;height:600px;}.legend {float:left;width:250px;margin-top:140px;}#content h1 {font-family:'Cabin Sketch', arial, serif;text-shadow:3px 3px 0 #ddd;color:#193340;font-size:40px;margin-bottom:40px;text-align:right;}.skills {float:left;clear:both;width:100%;}.skills ul,.skills li {display:block;list-style:none;margin:0;padding:0;}.skills li {float:right;clear:both;padding:0 15px;height:35px;line-height:35px;color:#fff;margin-bottom:1px;font-size:18px;}js代碼:
var o = { init: function () { this.diagram(); }, random: function (l, u) { return Math.floor((Math.random() * (u - l + 1)) + l); }, diagram: function () { var r = Raphael('diagram', 600, 600), rad = 73; r.circle(300, 300, 85).attr({ stroke: 'none', fill: '#193340' }); var title = r.text(300, 300, 'loading...').attr({ font: '20px Arial', fill: '#fff' }).toFront(); r.customAttributes.arc = function (value, color, rad) { var v = 3.6 * value, alpha = v == 360 ? 359.99 : v, random = o.random(91, 240), a = (random - alpha) * Math.PI / 180, b = random * Math.PI / 180, sx = 300 + rad * Math.cos(b), sy = 300 - rad * Math.sin(b), x = 300 + rad * Math.cos(a), y = 300 - rad * Math.sin(a), path = [['M', sx, sy], ['A', rad, rad, 0, +(alpha > 180), 1, x, y]]; return { path: path, stroke: color } } $('.get').find('.arc').each(function (i) { var t = $(this), color = t.find('.color').val(), value = t.find('.percent').val(), text = t.find('.text').text(); rad += 30; var z = r.path().attr({ arc: [value, color, rad], 'stroke-width': 26 }); z.mouseover(function () { this.animate({ 'stroke-width': 50, opacity: .75 }, 1000, 'elastic'); if (Raphael.type != 'VML') //solves IE problem this.toFront(); title.animate({ opacity: 0 }, 500, '>', function () { this.attr({ text: text + '/n' + value + '%' }).animate({ opacity: 1 }, 500, '<'); }); }).mouseout(function () { this.animate({ 'stroke-width': 26, opacity: 1 }, 1000, 'elastic'); }); }); } } $(function () { o.init(); });希望本文所述對大家學習javascript程序設計有所幫助。
