Catch 一個 URIError
js
try { decodeURIComponent("%"); } catch (e) { console.log(e instanceof URIError); // true console.log(e.message); // "malformed URI sequence" console.log(e.name); // "URIError" console.log(e.fileName); // "Scratchpad/1" console.log(e.lineNumber); // 2 console.log(e.columnNumber); // 2 console.log(e.stack); // "@Scratchpad/2:2:3\n" } 生成一個 URIError
js
try { throw new URIError("Hello", "someFile.js", 10); } catch (e) { console.log(e instanceof URIError); // true console.log(e.message); // "Hello" console.log(e.name); // "URIError" console.log(e.fileName); // "someFile.js" console.log(e.lineNumber); // 10 console.log(e.columnNumber); // 0 console.log(e.stack); // "@Scratchpad/2:2:9\n" } 規範
