嗨 alertfrancis ，



您可以使用 createElement 和 appendChild 执行此操作的JavaScript方法。

Hi alertfrancis,

You can use createElement and appendChild JavaScript methods to do this.

<div id="dynamicCheck">
   <input type="button" value="Create Element" onclick="createNewElement();"/>
</div>

<div id="newElementId">New inputbox goes here:</div>

JavaScript

<script type="text/JavaScript">
function createNewElement() {
    // First create a DIV element.
	var txtNewInputBox = document.createElement('div');

    // Then add the content (a new input box) of the element.
	txtNewInputBox.innerHTML = "<input type='text' id='newInputBox'>";

    // Finally put it where it is supposed to appear.
	document.getElementById("newElementId").appendChild(txtNewInputBox);
}
</script>
