示例代碼如下:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="div" style="background-color:rosybrown;width:500px;height:200px;">這里有文字</div>
<input type="button" onclick="deleteContent(true)" value="刪除內(nèi)容">
<input type="button" onclick="deleteContent(false)" value="刪除元素">
<script>
function deleteContent(test) {
var div=document.getElementById("div");
var range=document.createRange();
if (test){
range.selectNodeContents(div);
range.deleteContents();
}else{
range.selectNode(div);
range.deleteContents();
}
}
</script>
</body>
</html>
