当事件被触发时,图像不打印
我想在mousedown被解雇时绘制图像,但是我不能。当事件被触发时,图像不打印
我该怎么解决?
var brush = new Image(); brush.src = "/wp-content/uploads/new2022/20220327voicc/207154258.png"
brush.onload = function(){
$("<canvas></canvas>").appendTo("body");
\t var canvas = $('canvas');
\t var context = canvas[0].getContext('2d');
\t canvas.width(500).height(300); \t
\t $('canvas').mousedown(function(event){
alert('canvas clicked on coordinates ('+event.pageX+','+event.pageY+')');
\t contex.drawImage(brush, event.pageX, event.pageY); \t
\t })
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <body>
</body>
回答:
您输入了错误的单词 “背景”:
contex.drawImage(brush, event.pageX, event.pageY);
应该
context.drawImage(brush, event.pageX, event.pageY);
