Question

我在html文件中的函数不适用于我写得更高的错误。当我从中更改它时功能名称（...）到window.name = function（...）
但它无论如何都不起作用并写入 “write.name不是finction” 我的代码

<meta charset="UTF-8">
<title>Title</title>
<script type="text/javascript">
    function changeText(id) {
        id.innerHTML = "Ooops!";
    }

    function displayDate () {
        document.getElementById("demo").innerHTML = Date();
    }

    function addField () {
        document.getElementById("demo").innerHTML = Date();
    }

    function addInput(divName){
        var newdiv = document.createElement('div');
        newdiv.innerHTML = "<br>Select File to Upload:<br><input type="file" onchange="addInput('dynamicInput');"  name="fileName">";
        document.getElementById(divName).appendChild(newdiv);
        window.displayDate();
        window.addField();
    }
</script>
</head>
<body>

<h1 id="fff" onclick="changeText(this);">Click on this text!</h1>
<form action="/getimage" method="post" enctype="multipart/form-data">
    <div id="dynamicInput">
        <br>Select File to Upload:<br><input type="file" onchange="addInput('dynamicInput');"  name="fileName">
    </div>
    <input type="submit" value="Upload">
    <input type="button" value="Add another input" onClick="addInput('dynamicInput');">
</form>
<p id="demo"></p>

</body>

请帮忙！

Answer 1

您需要解决quotes问题\'和字符串onchange="addInput(\'dynamicInput\');"。而window.name未在您的dom中定义

＆＃13;

function changeText(id) {
  id.innerHTML = "Ooops!";
}

function displayDate() {
  document.getElementById("demo").innerHTML = Date();
}

function addField() {
  document.getElementById("demo").innerHTML = Date();
}

function addInput(divName) {
  var newdiv = document.createElement('div');
  newdiv.innerHTML = '<br>Select File to Upload:<br><input type="file" onchange="addInput(\'dynamicInput\');"  name="fileName">';
  document.getElementById(divName).appendChild(newdiv);
  window.displayDate();
  window.addField();
}

＆＃13;

<h1 id="fff" onclick="changeText(this);">Click on this text!</h1>
<form action="/getimage" method="post" enctype="multipart/form-data">
  <div id="dynamicInput">
    <br>Select File to Upload:<br><input type="file" onchange="addInput('dynamicInput');" name="fileName">
  </div>
  <input type="submit" value="Upload">
  <input type="button" value="Add another input" onClick="addInput('dynamicInput');">
</form>
<p id="demo"></p>

Answer 2

请注意，您需要转义双引号才能在另一个双引号内使用它们，或者使用单引号代替。

        newdiv.innerHTML = "<br>Select File to Upload:<br><input type='file' onchange='addInput('dynamicInput');' name='fileName'>";

为什么函数没有定义javascript
