javascript实现动态统计图开发实例

javascript实现动态统计图开发实例

具体代码如下
html代码:

<div> <div> <h1>汽车销量:</h1> <div> <ul> <li>大众</li> <li>丰田</li> <li>别克</li> <li>福特</li> <li>长安</li> </ul> </div> </div> <div></div> </div> <div> <div> <span>大众</span> <input type="hidden" value="95" /> <input type="hidden" value="#97BE0D" /> </div> <div> <span>丰田</span> <input type="hidden" value="90" /> <input type="hidden" value="#D84F5F" /> </div> <div> <span>别克</span> <input type="hidden" value="80" /> <input type="hidden" value="#88B8E6" /> </div> <div> <span>福特</span> <input type="hidden" value="53" /> <input type="hidden" value="#BEDBE9" /> </div> <div> <span>长安</span> <input type="hidden" value="45" /> <input type="hidden" value="#EDEBEE" /> </div> </div>

css代码:

#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代码:

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(); });
