要在画布上的圆圈内创建文本,请使用-
context.beginPath();
以下是画布-
$("#demo").on("click", "#canvas1", function(event) { var canvas = document.getElementById('canvas1'); if (canvas.getContext) { var context = canvas.getContext("2d"); var w = 25; var x = event.pageX; var y = Math.floor(event.pageY-$(this).offset().top); context.beginPath(); context.fillStyle = "blue"; context.arc(x, y, w/2, 0, 2 * Math.PI, false); context.fill(); context = canvas.getContext("2d"); context.font = '9pt'; context.fillStyle = 'white'; context.textAlign = 'center'; context.fillText('amit', x, y+4); } });
的HTML
<div id = demo> <canvas id = canvas1></canvas> </div>
