我在textarea处理similes。我正在尝试以下代码。

<script type="text/javascript">
    function insertSmiley(smiley)
    {

        var currentText = document.getElementsByName("replybody")[0];

        var smileyWithPadding = " " + smiley + " ";
        currentText.value += smileyWithPadding;
    currentText.focus();

    }

它的工作正常，但它在文本区域中显示的表情符号仅与:)这种格式相同。

但我需要显示这种格式

enter image description here

如果我添加，请单击文本区域上显示的smilie。这是可能的吗？如果这个可能，我该怎么做呢。请帮帮我。

看看这样的选择。如果你写下角色，表情符号会直接启动:-)然后会收到微笑。 代码可以自己完成一些。

答案 1 :(得分：0)

在您的文本框中，您可以使用:)文字笑脸。发送消息后，您可以简单地将:)微笑转换为图像。喜欢Gmail的聊天选项。

答案 2 :(得分：0)

您可以维护微笑数组，并基于userclick事件（您可以传递int no。或smile对象），它将比较它并简单地用Image替换文本。

$().ready(function () {
$('.imageSwitch').each(function () {
    string = $(this).text('MENU');
    $(this).html('<img src="images/temp.jpg" alt="' + string + '" />');
});

}）;
