"HTML5 canvas ctx.fillText无法实现换行"

The fillText() method draws filled text on the canvas. If you want to wrap the text, you can do this by splitting the text at a new line and calling filltext() multiple times. By doing this, you split the text into multiple lines and draw each line separately.

You can try running the following code snippet −

var c = $('#c')[0].getContext('2d');
c.font = '12px Courier';
alert(c);

var str = 'first line second line...';
var a = 30;
var b = 30;
var lineheight = 15;
var lines = str.split('');

for (var j = 0; j<lines.length; j++)
c.fillText(lines[j], a, b + (j*lineheight) );
// for canvas
<canvas id="c" width="200" height="200"></canvas>

// CSS

canvas {
   background-color: #FFCE9E;
}
