Question

当我被枪杀时，我想要画一幅画像，但我不能。

我应该修理什么？

var brush = new Image();
brush.src = "http://icons.iconarchive.com/icons/designcontest/vintage/256/Brush-icon.png"

brush.onload = function(){
    $("<canvas></canvas>").appendTo("body");
	var canvas = $('canvas');
	var context = canvas[0].getContext('2d');
	canvas.width(500).height(300);	
  
	$('canvas').mousedown(function(event){
        alert('canvas clicked on coordinates ('+event.pageX+','+event.pageY+')'); 
    	contex.drawImage(brush, event.pageX, event.pageY); 	
	})  
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<body>
</body>

Answer 1

您错误输入了单词＆＃34; context＆＃34;：

contex.drawImage(brush, event.pageX, event.pageY);

应该是

context.drawImage(brush, event.pageX, event.pageY);

触发事件时图像不会打印
