在JavaScript中使用wordbreak属性可为非CJK脚本设置换行规则。以下是CJK脚本：C代表中文，J代表日语，K代表朝鲜语。
您可以尝试运行以下代码以了解如何实现wordbreak属性-
<!DOCTYPE html>
<html>
<head>
<style>
#box {
width: 150px;
height: 120px;
background-color: lightblue;
border: 1px solid black;
}
</style>
</head>
<body>
<button onclick = "display()">Set</button>
<div id = "box">
This is Demo Text.This is Demo Text.This is Demo Text.This is Demo Text.This is Demo Text.This is Demo Text.
</div>
<script>
function display() {
document.getElementById("box").style.wordBreak = "break-all";
}
</script>
</body>
</html>
