我正在尝试这样做，以便当我选择某个单选按钮时，它将更改文本框中用户将输入单词的字体。如何在选择特定单选按钮时更改字体？

    <?php if (!empty($_GET[ 'message'])) { $message=$ _GET[ 'message']; for ($i=0 ; $i < strlen($message); ++$i) { $char=substr($message, $i, 1); if ($char !=" " ) { echo "<img src='/sandvig/Images/Alphabet/deco/blue/{$char}1.gif'>\n" ; } else { echo "<br />\n"; } } } ?> </form>

Answer 1

我不知道这或多或少是你要做的事情，但就像我说你可以用css这样做...这只是设置颜色，但你可以改变这样的所有属性

我猜不过，当用户点击public class Data { ... public void computeSomething() { swith(category){ case MMM : computeMMM();break; case MMO : computeMMO();break; ... } } private void computeMMM(){ ... } private void computeMMO(){ ... } }时，您希望字体更改，但这不是您之前尝试的内容。

submit

尝试：

<input type="text" <?php if (isset($_GET['font'])) echo "style='font-family: \"{$_GET['font']}\";'"; ?> name="message" required size="50" value="The Quick Brown Fox Jumps Over the Lazy Dog" autofocus>

我需要帮助在PHP中的单选按钮
