本文实例讲述了javascript实现动态统计图的代码。分享给大家供大家参考。具体如下:
运行效果截图如下:
具体代码如下
html代码:
汽车销量: 大众 丰田 别克 福特 长安
大众
丰田
别克
福特
长安
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(); });
