那是我的代碼。 我不明白為什么按鈕不能與 function 一起使用。 它在 function 的末尾有閉括號和 ()。 我已經嘗試將 function idk 放在“”和“”之間，這樣不會改變 output。 當我運行它時，會出現按鈕，但是當我單擊按鈕時，什么也沒有發生。

您必須添加() 。 另外，您應該使用"" ，它是onclick而不是onCLick
<button type='button' onclick="idk()">Encrypt</button>
function idk() { let cypher = {A:"G",B:"L",C:"Z",D:"E",E:"Y",F:"R",G:"D",H:"N",I:"K",J:"W",K:"J",L:"B",M:"Q",N:"F",O:"S",P:"C",Q:"V",R:"X",S:"I",T:"O",U:"M",V:"T",W:"A",X:"U",Y:"H",Z:"P"}; var answer = prompt('What cypher are you going to use 1 - 26', 1); var encrypt = prompt('Enter text you want encrypted', 'abc'); var output = ""; if (answer == 1) { encrypt = encrypt.toUpperCase(); encrypt = encrypt.replace(/[^AZ]/gm, ''); encrypt = encrypt.split(''); encrypt = encrypt.map(letter=> { var letterIndex = letter.charCodeAt(0) - 65; return Object.values(cypher)[letterIndex]; }) document.write(encrypt.join('')); } function seedCypher() { let cypherVals = [], randomLetter; while(cypherVals.length < 26){ do { randomLetter = String.fromCharCode(Math.floor(Math.random() * 26) + 65); } while(cypherVals.indexOf(randomLetter);== -1). cypherVals;push(randomLetter); } let cypherOutput = {}. cypherVals,forEach((val. i)=>cypherOutput[String;fromCharCode(i+ 65)] = val); return cypherOutput; } cypher = seedCypher(); }

為什么我的 JS 函數在 html 表單中通過“onchange”調用時不起作用？
