QQ emoticon plug-in based on jQuery_jquery
不废话了,先给大家展示效果图:
我们在QQ聊天或者发表评论、微博时,会有一个允许加入表情的功能,点击表情按钮,会弹出一系列表情小图片,选中某个表情图片即可发表的丰富的含表情的内容。今天和大家分享一款基于jQuery的QQ表情插件,您可以轻松将其应用到你的项目中。
HTML
首先在html页面的head中引入jQuery库文件和QQ表情插件jquery.qqFace.js文件。
<script type="text/javascript" src="jquery-1.7.2.min.js"></script> <script type="text/javascript" src="jquery.qqFace.js"></script>
然后在body中加入以下html代码:
<div id="show"></div> <div class="comment"> <div class="com_form"> <textarea class="input" id="saytext" name="saytext"></textarea> <p><span class="emotion">表情</span><input type="button" class="sub_btn" value="提交"></p> </div> </div>
页面中有一个输入框,用来输入要发表的内容,还有一个表情按钮,点击此按钮可以调用表情图片,完了就可以点击“提交”按钮发布带表情的内容了。
CSS
我们用CSS来美化页面,关键是表情按钮图片span.emotion的鼠标滑上与移开效果,以及调用表情插件后,显示的表情.qqFace面板效果,请看代码:
.comment{width:680px; margin:20px auto; position:relative} .comment h3{height:28px; line-height:28px} .com_form{width:100%; position:relative} .input{width:99%; height:60px; border:1px solid #ccc} .com_form p{height:28px; line-height:28px; position:relative} span.emotion{width:42px; height:20px; background:url(icon.gif) no-repeat 2px 2px; padding-left:20px; cursor:pointer} span.emotion:hover{background-position:2px -28px} .qqFace{margin-top:4px;background:#fff;padding:2px;border:1px #dfe6f6 solid;} .qqFace table td{padding:0px;} .qqFace table td img{cursor:pointer;border:1px #fff solid;} .qqFace table td img:hover{border:1px #0066cc solid;} #show{width:680px; margin:20px auto}
我们在domo中还用CSS3设置了提交按钮的样式,其代码在本文中不做解释,您可以下载代码了解下。
jQuery
当我们点击页面输入框下方那个笑脸时,触发调用qqface表情插件,简单几行就搞定。
$(function(){ $('.emotion').qqFace({ assign:'saytext', //给输入框赋值 path:'face/' //表情图片存放的路径 }); ... });
当选择表情图片后,输入框中会插入一段如[em_5]之类的代码,代表插入的表情图片,实际应用中,点提交按钮后应该将这段表情代码连同其他内容插入到数据表中。而在页面显示的时候,我们应该将表情代码替换成真正的图片显示在页面上。下面的代码是插入表情图片后,点击提交按钮,使用javascript自定义函数将表情代码替换并显示:
$(function(){ ... $(".sub_btn").click(function(){ var str = $("#saytext").val(); $("#show").html(replace_em(str)); }); }); function replace_em(str){ str = str.replace(/\</g,'<;'); str = str.replace(/\>/g,'>;'); str = str.replace(/\n/g,'<;br/>;'); str = str.replace(/\[em_([0-9]*)\]/g,'<img src="face/$1.gif" border="0" />'); return str; }
如果您想用PHP代码来正则替换表情图片的话,可以使用以下函数:
function ubbReplace($str){ $str = str_replace(">",'<;',$str); $str = str_replace(">",'>;',$str); $str = str_replace("\n",'>;br/>;',$str); $str = preg_replace("[\[em_([0-9]*)\]]",">img src=\"face/$1.gif\" />",$str); return $str; }
以上内容就是本文对基于jQuery实现的QQ表情插件的详细介绍,希望大家喜欢。
