设置选项

你可以通过编程方式设置选项，方法是将它们设置在 less 对象 before 脚本标记上 - 这会影响所有初始链接标记和 less 的编程使用。

<script>
  less = {
    env: "development",
    async: false,
    fileAsync: false,
    poll: 1000,
    functions: {},
    dumpLineNumbers: "comments",
    relativeUrls: false,
    rootpath: ":/a.com/"
  };
</script>
<script src="less.js"></script>

另一种方法是在脚本标签上指定选项，例如

<script>
  less = {
    env: "development"
  };
</script>
<script src="less.js" data-env="development"></script>

或者为简洁起见，可以将它们设置为脚本和链接标签上的属性：

<script src="less.js" data-poll="1000" data-relative-urls="false"></script>
<link data-dump-line-numbers="all" data-global-vars='{ "myvar": "#ddffee", "mystr": "\"quoted\"" }' rel="stylesheet/less" type="text/css" href="less/styles.less">
