要清除画布上的图表，请删除5ba626b379994d53f7acf72a64f9b697元素，然后将一个新的5ba626b379994d53f7acf72a64f9b697元素附加到父容器中，如下所示的代码：
var resetcanvas = function(){ $('#results-graph').remove(); $('#graph-container').append('<canvas id = "results-graph"><canvas>'); canvas = document.queryselector('#results-graph'); ct = canvas.getcontext('2d'); ct.canvas.width = $('#graph').width(); // here we are resizing the new canvas element to parent width ct.canvas.height = $('#graph').height(); // here we are resizing the new canvas element to parent height var a = canvas.width/2; var b = canvas.height/2; ct.font = '12pt calibri'; ct.textalign = 'align left'; ct.filltext('left aligned text on the canvas', a, b);};
以上就是如何清除html5画布上的图表，以防止触发悬停事件？的详细内容。
