这个是偶然打开JS 时,看到了这个界面,然后想加点东西上去,便做了这个小功能
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>网页追加评论</title> <style type="text/css"> #outside { width: 1000px; margin: 0 auto; border: 1px solid #E7EAEE; overflow: hidden; padding-bottom: 15px; } #outside h3 { width: 95%; margin: 15px auto; padding-bottom: 10px; border-bottom: 1px solid #E7EAEE; font-family: "宋体", sans-serif; } #outside .comment1 { width: 95%; margin: 10px auto; color: #BBBBBB; font-size: 12px; border-bottom: 1px dashed #E7EAEE; font-family: "宋体", sans-serif; position: relative; } #outside .comment1 time { float: right; } #outside .comment1 span { color: #5979B2; margin-left: 5px; font-weight: bold; } #outside .comment1 p { font-size: 16px; color: black; } #zan{ width: 60px; position: absolute; right: 65px; bottom: 16px; } #zan img { width: 16px; height: 16px; position: absolute; bottom: 0; } #zan span { color: #97D6C0; font-size: 12px; font-weight: bold; position: absolute; left: 21px; bottom: 0; } #comment1 #span11{ font-size: 12px; letter-spacing: 2px; color: #BBBBBB; cursor: pointer; position: absolute; right: 35px; bottom: 17px; } #outside h4 { width: 95%; margin: 15px auto; color: #404E73; font-size: 16px; font-weight: bold; font-family: "宋体", sans-serif; } #outside #addComment { width: 95%; margin: 0 auto; font-size: 12px; color: #BBBBBB; } #outside #name { width: 200px; border: 1px solid #D9E2EF; } #outside #comContent { width: 800px; height: 100px; resize: none; border: 1px solid #D9E2EF; vertical-align: text-top; } #outside button { width: 100px; height: 30px; background-color: #2D46A3; color: white; border: hidden; float: right; margin: 15px 100px; } </style> </head> <body> <div id="outside"> <h3>最新平均</h3> <div id="comment"> <div id="comment1" class="comment1"> 腾讯网友 <span>123</span> <time>2010年10月5日 19:21:12</time> <p> 123 </p> <div id="zan" class="zan1" onclick="test(this)"> <img src="img/zanb.png" class="img1"/> <span id="span1"></span> <!--<span id="span11" class="span11">回复</span>--> </div> <span id="span11" class="span11">回复</span> </div> </div> <h4>发表评论</h4> <div id="addComment"> 昵 称:<input type="text" id="name" /> <br /><br /> 评论内容: <textarea id="comContent"></textarea> <button onclick="addComment()">提交评论</button> </div> </div> <script type="text/javascript"> var id = 1; var span1 = document.getElementById("span1"); function addComment() { var name = document.getElementById("name").value; var comContent = document.getElementById("comContent").value; if(name == "" || comContent == "") { alert("用户名和评论内容不可为空!"); return; } id++; var dates = new Date(); var year = dates.getFullYear(); var month = dates.getMonth(); var date1 = dates.getDate(); var hours = dates.getHours() < 10 ?

这个可以动态获取用户评论时间,一个简单的点赞功能
