我第一次尝试用a做的,效果很好。
<button type="button" class="btn btn-default glyphicon glyphicon-arrow-left"></button>
&#13;
但是,当我尝试对canvas对象执行相同操作时,在这种情况下,chart.js库生成的折线图不起作用。我使用d3.js将图表插入svg。我还在我的angularjs chart.js指令中设置了一个断点(我通过指令使用了chart.js),我注意到该指令根本没有被调用。
带有chart.js画布的foreignObject正在插入到html中,只是没有渲染。
<foreignObject x="5" y="5">
<canvas id="line" class="chart chart-line" data="data" labels="labels" legend="true" series="series" click="onClick"></canvas>
</foreignObject>
&#13;
还有其他人有过类似的问题吗?
答案 0 :(得分:2)
查看生成的HTML
您需要在foreignObject
上设置高度和宽度 ...
.append("xhtml:body")
.html('<canvas id="line" class="chart chart-line" data="data" labels="labels" legend="true"></canvas>');
并将画布附加到foreignObject
下的body元素var app = angular.module("app", ["chart.js"]);
app.controller("chartController", ['$scope',
function($scope) {
$scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
$scope.data = [
[65, 59, 80, 81, 56, 55, 40],
[28, 48, 40, 19, 86, 27, 90]
];
}
])
d3.select("svg")
.append("foreignObject")
.attr("width", 480)
.attr("height", 500)
.append("xhtml:body")
.html('<canvas id="line" class="chart chart-line" data="data" labels="labels"></canvas>');
这是一个工作代码段(请与Chrome核实)
