我目前正在尝试通过基本字体大小变量基于全局样式表动态设置文本大小。我目前正在使用方法 tfWidthController 来检查宽度是否大于所需宽度，如果是，则减小 css 中的字体大小并重新解析 css 并使其自动调整大小。但由于某种原因，它没有自动调整大小，而是正在操纵 css。你看到我做错了什么吗？感谢您花时间帮助我！

我想通了 - 每次调整大小时都需要更改 htmlText。

while ($_tfCurrentWidth > maxTextFieldWidth) {
    trace ('$_tfCurrentWidth is '+$_tfCurrentWidth);
    trace ('maxTextFieldWidth is '+maxTextFieldWidth);
    var oldHtml:String = tf.htmlText;
    tf.htmlText = '';
    tf.htmlText = oldHtml;
    baseFontSize-=1;
    applyStyles();
}

我也为此做了一个工作测试，你可以在这里看到它： http ://wonderfl.net/c/A310
