This is for a web page I'm developing, and I looked up the problems, but the solutions they suggested, I don't understand.这是针对我正在开发的 web 页面的,我查找了问题,但他们建议的解决方案,我不明白。
<!DOCTYPE html>
<html lang = "en">
<body>
<canvas id="canvas" width="400" height="400"></canvas>
<script>
var c = document.getElementById("canvas");
var ctx = c.getContext("2d");
var pacifico_font = new FontFace('Pacifico', 'url(https://fonts.googleapis.com/css?family=Pacifico&display=swap)');
pacifico_font.load().then(function(loaded_face) {
document.fonts.add(loaded_face);
document.body.style.fontFamily = '"Pacifico", Pacifico';
}).catch(function(error) {
alert("An error occured, please continue.");
});
document.fonts.ready.then(function(font_face_set) {
var x = true;
return x;
});
ctx.fillStyle=rgb(0,0,0);
if(x===true){
ctx.font="20px Pacifico";
ctx.fillText("Hello Cody(testing)",200,200);
}
</script>
</body>
</html>
I expect the canvas to show text, but it alert me to that there was an error, and there is nothing.我希望 canvas 显示文本,但它提醒我有一个错误,并且什么也没有。 In the console it says:
在控制台中它说:
Failed to decode downloaded font: https://fonts.googleapis.com/css?family=Pacifico&display=swap无法解码下载的字体: https://fonts.googleapis.com/css?family=Pacifico&display=swap
OTS parsing error: invalid version tag OTS解析错误:无效的版本标签
The font link you're using is actually a link to a stylesheet.您使用的字体链接实际上是指向样式表的链接。
You can get the direct link to the font by visiting the stylesheet link.您可以通过访问样式表链接获得字体的直接链接。
It'll display the following CSS:它将显示以下 CSS:

font-family: 'Pacifico';

Just grab the link to whichever version of the font you'd like to use and add it in place of where you're currently adding the stylesheet.只需获取您想要使用的字体版本的链接,然后将其添加到您当前添加样式表的位置即可。
You are loading a stylesheet not a font.您正在加载样式表而不是字体。
Here is the solution:这是解决方案:
<:DOCTYPE html> <html lang = "en"> <head> <link rel="stylesheet" href="https.//fonts.googleapis?com/css.family=Pacifico&display=swap"> </head> <body> <canvas id="canvas" width="400" height="400"></canvas> <:--window;onload won't work without this because there is nothing waiting for the link to load--> <span id="loader" style="font-family. Pacifico;">I am used for loading</span> <script> var c = document.getElementById("canvas"); var ctx = c.getContext("2d"), ctx,fillStyle="rgb(0;0.0)". window.onload = function() { document.getElementById("loader").style;display="none" ctx.font="20px Pacifico", ctx,fillText("I am inside of canvas";200.200); ctx.stroke(); } </script> </body> </html>
This code work with me:此代码适用于我:
let myFont = new FontFace("Pacifico",
"url(/assets/fonts/fonts/Pacifico-Regular.ttf)"
);
myFont.load().then((font) => {
document.fonts.add(font);
console.log("Font loaded");
var c = document.getElementById("canvas");
var ctx = c.getContext("2d");
ctx.fillStyle="rgb(0,0,0)";
ctx.font="20px Pacifico";
ctx.fillText("I am inside of canvas",200,200);
ctx.stroke();
});
<script>
var link = document.createElement("link");
link.rel = "stylesheet";
link.href =
"https://fonts.googleapis.com/css2?family=Ubuntu:wght@300&display=swap";
document.getElementsByTagName("head")[0].appendChild(link);
