我想在單擊按鈕時使用JavaScript插入文本。但是```.value()```似乎不起作用-有解無憂

這是代碼片段。請幫我解決這個錯誤：/我想做的是當我點擊按鈕時，它應該在輸入欄中插入一些值

function insertText() {
  try {
    document.querySelector('#input').value('Clicked');
  } catch (err) {
    console.log("ERROR")
  }
}

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.container {
  height: 60vh;
  width: 100vw;
  display: grid;
  place-items: center;
  border: 2px solid blue;
}

.btn {
  height: 40vh;
  border: 2px solid red;
  width: 100vw;
  display: grid;
  place-items: center;
}

.btn>button {
  padding: 10px 40px;
}

<div class="container">
  <input type="text" value="" id="input">
</div>
<div class="btn">
  <button oncanplay="insertText()" id="butt">INSERT SOME TEXT</button>
</div>

function insertText(){
            try{
                document.querySelector('#input').value = "Lorem Ipsum";
            }catch(err){
                console.log("ERROR");
            }
        }

*{
            margin: 0;

您可以使用此 jQuery 函式將文本添加到輸入中。

 <script>
            $(document).ready(function () {
                $("#setBtnID").click(function () {
                    $("input:text").val("Hello World!");
                });
            });
        </script>

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.container {
  height: 60vh;
  width: 100vw;
  display: grid;
  place-items: center;
  border: 2px solid blue;
}

.btn {
  height: 40vh;
  border: 2px solid red;
  width: 100vw;
  display: grid;
  place-items: center;
}

.btn>button {
  padding: 10px 40px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<head>
<script>
        $(document).ready(function () {
            $("#setBtnID").click(function () {
                $("input:text").val("Hello World!");
            });
        });
    </script>
    </head>
<body>
<div class="container">
  <input type="text" value="" id="input">
</div>
<div class="btn">
  <button  id="setBtnID">INSERT SOME TEXT</button>
</div>
</body>
