[英]How would I import fonts from google fonts into javascript, so i can use it for my canvas?
我正在嘗試將谷歌 fonts 導入 javascript，這樣我就可以使用 fonts 在我的 ZFCC5790C72ADCDfonts 上繪制文本問題是我收到錯誤。
錯誤1：解碼下載fonts失敗
錯誤2：OTS解析錯誤
這是針對我正在開發的 web 頁面的，我查找了問題，但他們建議的解決方案，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>
我希望 canvas 顯示文本，但它提醒我有一個錯誤，並且什么也沒有。 在控制台中它說：
無法解碼下載的字體： https://fonts.googleapis.com/css?family=Pacifico&display=swap
OTS解析錯誤：無效的版本標簽
您使用的字體鏈接實際上是指向樣式表的鏈接。
您可以通過訪問樣式表鏈接獲得字體的直接鏈接。
它將顯示以下 CSS：
/* cyrillic-ext */
@font-face {
font-family: 'Pacifico';
font-style: normal;
font-weight: 400;
src: local('Pacifico Regular'), local('Pacifico-Regular'), url(https://fonts.gstatic.com/s/pacifico/v16/FwZY7-Qmy14u9lezJ-6K6MmBp0u-zK4.woff2) format('woff2');

}
/* cyrillic */
@font-face {

font-style: normal;
font-weight: 400;

unicode-range: U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116;
}
/* vietnamese */
@font-face {
font-family: 'Pacifico';
font-style: normal;
font-weight: 400;
src: local('Pacifico Regular'), local('Pacifico-Regular'), url(https://fonts.gstatic.com/s/pacifico/v16/FwZY7-Qmy14u9lezJ-6I6MmBp0u-zK4.woff2) format('woff2');

}

@font-face {

unicode-range: U+0100-024F, U+0259, U+1E00-1EFF, U+2020, U+20A0-20AB, U+20AD-20CF, U+2113, U+2C60-2C7F, U+A720-A7FF;

/* latin */
@font-face {

font-weight: 400;
src: local('Pacifico Regular'), local('Pacifico-Regular'), url(https://fonts.gstatic.com/s/pacifico/v16/FwZY7-Qmy14u9lezJ-6H6MmBp0u-.woff2) format('woff2');

}
只需獲取您想要使用的字體版本的鏈接，然后將其添加到您當前添加樣式表的位置即可。
您正在加載樣式表而不是字體。
這是解決方案：
<: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>此代碼適用於我：
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);
</script>
