要设置列表项标记的位置，请使用listStylePosition属性。您可以尝试运行以下代码以使用JavaScript设置列表项标记的位置-
<!DOCTYPE html>
<html>
<body>
<ol id="myID">
<li>One</li>
<li>Two</li>
</ol>
<button type="button" onclick="displayInside()">Add list inside</button>
<button type="button" onclick="displayOutside()">Add list outside</button>
<script>
function displayInside() {
document.getElementById("myID").style.listStylePosition = "inside";
}
function displayOutside() {
document.getElementById("myID").style.listStylePosition = "outside";
}
</script>
</body>
</html>
