WP技巧：一句代码调用WordPress表情

关于WordPress评论插件有很多很多，不少插件功能是提供表情调用的。
其实WordPress本身就是带有表情图标的，现在你只需在你的主题文件中添加一些简单的代码就可以实现了，不仅可以给你博客的读者提供评论的便利，亦可免去使用那些表情调用插件了。
全部代码如下：

<script type="text/javascript" language="javascript">
/* <![CDATA[ */
function grin(tag) {
var myField;
tag = ' ' + tag + ' ';
if (document.getElementById('comment') && document.getElementById('comment').type == 'textarea') {
myField = document.getElementById('comment');
} else {
return false;
}
if (document.selection) {
myField.focus();
sel = document.selection.createRange();
sel.text = tag;
myField.focus();
}
else if (myField.selectionStart || myField.selectionStart == '0') {
var startPos = myField.selectionStart;
var endPos = myField.selectionEnd;
var cursorPos = endPos;
myField.value = myField.value.substring(0, startPos)
+ tag
+ myField.value.substring(endPos, myField.value.length);
cursorPos += tag.length;
myField.focus();
myField.selectionStart = cursorPos;
myField.selectionEnd = cursorPos;
}
else {
myField.value += tag;
myField.focus();
}
}
/* ]]> */
</script>

你只需将以上代码添加在主题“comments.php”文件评论框代码上边的合适位置就行了。
当然可能会有读者讨厌这么一长串的代码比较烦人，没关系这边还有另外一种方法：就是将上述代码保存为一个“smiley.php”，然后上传到主题文件夹内。然后在主题“comments.php”文件评论框的适当位置使用如下代码调用：

当位置使用如下代码调用：

就是这么简单，以上都是参考自互联网的！
