是否有可能的按钮＆＃34;添加＆＃34;会在表单中生成新的textarea吗？我一整天都在搜索但是找不到任何逻辑可以做到＆＃34;添加＆＃34;生成新textarea的函数。

h1,h2,h3,h4,h5,p,table {font-family: Calibri;}
.content {
  margin: 0 auto;
  width: 75%;
  margin-top: 15px;
}
table.addbutton {
  border: solid black 1px;
  width: 100%;
  height: auto;
}
td,th,tr {
  border: solid black 1px;
  text-align: center;
}
textarea {
  width: 100%;
  margin: 0;
  overflow: hidden
}

这是一个生成文本区域

的示例

＆＃13;

＆＃13;

function myFunction() {
    var x = document.createElement("FORM");
    x.setAttribute("id", "myForm");
    document.body.appendChild(x);

    var y = document.createElement("TEXTAREA");
    document.getElementById("myForm").appendChild(y);
}

＆＃13;

<button onclick="myFunction()">Add</button>

＆＃13;
