HTML5 中是否存在跨域屬性?
是的,官方規範將跨域屬性規定為
The crossorigin attribute is a CORS settings attribute. Its purpose is to allow images from third-party sites that allow cross-origin access to be used with canvas.
你可以使用它來解決 JavaScript 錯誤,例如記錄 js 錯誤
if (securityOrigin()->canRequest(targetUrl)) {
msg = myErroe;
line = myLineNumber;
source = sourceURL;
} else {
msg = "Error!";
source = String();
line = 0;
}
