我正在尝试用Travis Palmer修改笔(http://codepen.io/anon/pen/JgyCz),以便我可以在多个元素上使用它。我们正在尝试在页面上放置几个<div class="donut" data-donut="x">
。
所以它看起来与下面的html类似:
////// HTML
<div class="donut" data-donut="22"></div>
<div class="donut" data-donut="48"></div>
<div class="donut" data-donut="75></div>
我试图转换为可重用的compunent的D3.js / jQuery示例如下。 (要查看完整的工作示例,请转到此链接 - http://codepen.io/anon/pen/JgyCz)
////// D3.js
var duration = 500,
transition = 200;
drawDonutChart(
'.donut',
$('.donut').data('donut'),
290,
290,
".35em"
);
function drawDonutChart(element, percent, width, height, text_y) {
width = typeof width !== 'undefined' ? width : 290;
height = typeof height !== 'undefined' ? height : 290;
text_y = typeof text_y !== 'undefined' ? text_y : "-.10em";
var dataset = {
lower: calcPercent(0),
upper: calcPercent(percent)
},
radius = Math.min(width, height) / 2,
pie = d3.layout.pie().sort(null),
format = d3.format(".0%");
var arc = d3.svg.arc()
.innerRadius(radius - 20)
.outerRadius(radius);
var svg = d3.select(element).append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
var path = svg.selectAll("path")
.data(pie(dataset.lower))
.enter().append("path")
.attr("class", function(d, i) { return "color" + i })
.attr("d", arc)
.each(function(d) { this._current = d; }); // store the initial values
var text = svg.append("text")
.attr("text-anchor", "middle")
.attr("dy", text_y);
if (typeof(percent) === "string") {
text.text(percent);
}
else {
var progress = 0;
var timeout = setTimeout(function () {
clearTimeout(timeout);
path = path.data(pie(dataset.upper)); // update the data
path.transition().duration(duration).attrTween("d", function (a) {
// Store the displayed angles in _current.
// Then, interpolate from _current to the new angles.
// During the transition, _current is updated in-place by d3.interpolate.
var i = d3.interpolate(this._current, a);
var i2 = d3.interpolate(progress, percent)
this._current = i(0);
return function(t) {
text.text( format(i2(t) / 100) );
return arc(i(t));
};
}); // redraw the arcs
}, 200);
}
};
function calcPercent(percent) {
return [percent, 100-percent];
};

执行此操作的最佳方法是使用angular指令。角度指令基本上将html包装在自定义标记内,让你在多个页面上反复标记指令或多次在页面上标记。观看此视频:http://www.youtube.com/watch?v=aqHBLS_6gF8
还有一个名为nvd3.js的库,它包含可以重复使用的预构建角度指令:http://nvd3.org/
希望这有帮助。
