HTML DOM whiteSpace 属性
定义和用法
whiteSpace 属性设置如何处理文本中的空白符（比如空格和换行符）。
语法：
Object.style.whiteSpace=normal|nowrap|pre
可能的值
| 值 | 描述 |
|---|---|
| normal | 默认。空白会被浏览器忽略。 |
| pre | 空白会被浏览器保留。其行为方式类似 HTML 中的 <pre> 标签。 |
| nowrap | 文本不会换行，文本会在在同一行上继续，直到遇到 <br> 标签为止。 |
实例
本例不允许在文本内换行：
<html>
<head>
<script type="text/javascript">
function removeWrapping()
{
document.getElementById("div1").style.whiteSpace="nowrap";
}
</script>
</head>
<body>
<div id="div1">
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
</div>
<br />
<input type="button" onclick="removeWrapping()"
value="Do not let the text wrap" />
</body>
</html>TIY
