一个简单的前端静态聊天界面，实现了聊天的基本功能，目前后台还没做，接下来还会继续更新后台和完善前台样式并更新。
一.Html代码
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>chat</title> <link rel="stylesheet" href="../css/chat.css" type="text/css"> <script type="text/javascript" src="../js/chat.js"></script> </head> <body> <p class="all"> <p class="chat_index"> <!--banner--> <p class="chat_banner"> </p> <p class="chat_body"> <!--在线列表--> <p class="chat_online"> <!--搜索--> <p class="search_online"> <form> <input type="text" placeholder="搜索联系人"> </form> </p> <p class="online_friend"> <ul> <li> <p class="a_friend"> <p class="head_portrait"> <p class="head_text"> 黄 </p> </p> <p class="friend"> <p class="name">天狼星</p> <p class="this_time">4-12-15:10</p> </p> </p> </li> <li> <p class="a_friend"> <p class="head_portrait"> <p class="head_text"> 黄 </p> </p> <p class="friend"> <p class="name">天狼星</p> <p class="this_time">4-12-15:10</p> </p> </p> </li> <li> <p class="a_friend"> <p class="head_portrait"> <p class="head_text"> 黄 </p> </p> <p class="friend"> <p class="name">天狼星</p> <p class="this_time">4-12-15:10</p> </p> </p> </li> <li> <p class="a_friend"> <p class="head_portrait"> <p class="head_text"> 黄 </p> </p> <p class="friend"> <p class="name">天狼星</p> <p class="this_time">4-12-15:10</p> </p> </p> </li> </ul> </p> </p> <!--聊天界面--> <p class="chat_main"> <p class="chat_p"> <ul id="chat_ul" class="chat_content"> </ul> </p> <p class="send_message"> <form> <input type="text" placeholder="请输入消息" id="send_txt"> <input type="button" value="发送" id="send_btn"> </form> </p> </p> <!--名片--> <p class="chat_namecard"> </p> </p> </p> </p> </body> </html>
二.CSS代码
有些需要注意的地方已经标上注释了
* { margin: 0; padding: 0; font-size: 12px; font-family: "微软雅黑"; } .all { width: 100%; height: 790px; /*background-color: #7fa4f2;*/ background: linear-gradient(to right, #879eee, #ba78dc); /* 标准的语法 */ } .chat_index { width: 1000px; height: 600px; border: 1px solid black; position: relative; top: 100px; margin: 0 auto; } .chat_banner { background: linear-gradient(to right, #a41adc, #ee1351, #a41adc); /* 标准的语法 */ width: 999px; height: 50px; border: 1px solid blue; } .chat_body { width: 999px; height: 546px; border: 1px solid red; } .chat_online { overflow: hidden; float: left; height: 546px; width: 200px; border: 1px solid yellow; background-color: white; } .search_online { text-indent: 2em; height: 40px; border: 1px solid black; } .search_online input[type="text"] { outline: none; margin: 2px auto; height: 30px; width: 60%; border-radius: 8px; text-indent: 2em; } .online_friend ul li { list-style-type: none; } .online_friend ul li { height: 60px; border-bottom: 1px solid #1c1f21; margin-top: 10px; } .a_friend { /*border: 1px solid #2328ff;*/ height: 55px; background-color: #39fffe; } .head_portrait { background-color: #b532ff; margin: 6px 6px; float: left; height: 40px; width: 40px; border: 1px solid orangered; border-radius: 50%; } .head_text { padding: 3px; font-size: 22px; text-align: center; vertical-align: center; margin-top: 3px; } .friend { float: right; height: 54px; width: 140px; /*border: 1px solid rebeccapurple;*/ } .friend .name { margin: 4px 6px; float: left; } .friend .this_time { margin-top: 4px; float: right; } .chat_main { float: left; width: 548px; height: 546px; border: 1px solid seagreen; /*background-color: white;*/ background: url("../img/圣诞.jpg") no-repeat; background-size: cover; } .send_message { width: 548px; height: 65px; position: absolute; bottom: 0px; background: linear-gradient(to top, rgba(9, 216, 237, 0.99), #72cad4); } .send_message input[type="text"] { width: 470px; height: 30px; margin-top: 16px; margin-left: 10px; border-radius: 10px 0 0 10px; text-indent: 2em; outline: none; background-color: white; border: none; } .send_message input[type="button"] { border-radius: 0 10px 10px 0; width: 35px; height: 30px; background-color: white; border: none; margin-left: 0; background-color: white; border: none; outline: none; } .send_message input[type="button"]:hover { background-color: orangered; } .send_message input[type="button"]:active { background-color: #879eee; } .chat_namecard { float: left; width: 245px; height: 546px; border: 1px solid saddlebrown; background-color: #f1fea9; } .chat_content ul{ list-style-type: none; } .chat_content{ overflow: auto; width: 540px; /*设置高度滚动条才有效*/ height: 470px; } .chat_content li{ margin-top: 10px; width: 540px; clear: both; display: block; } .chat_content li img{ margin: 6px 0 0 0; } .chat_content li span { background: #ffd351; padding: 10px; border-radius: 10px; /*最大宽度不能太长，不然布局会混乱*/ max-width: 400px; border: 1px solid white; box-shadow: 0 0 3px #879eee; margin: 6px 10px 0 10px; overflow: hidden; } .chat_content li img { width: 40px; height: 40px; border-radius: 50%; } .chat_content li img.imgleft { margin-left: 10px; float: left; } .chat_content li img.imgright { margin-right: 10px; float: right; } .chat_content li span.spanleft { float: left; } .chat_content li span.spanright { float: right; }
三.JS代码
window.onload = function () { var user = ["../img/img_17.jpg"]; var num = 1;//判断左右 var portrait_position = 0; var now = -1;//左右浮动 var send_btn = document.getElementById('send_btn'); var send_txt = document.getElementById('send_txt'); var chat_ul = document.getElementById('chat_ul'); var chat_span = chat_ul.getElementsByTagName('span'); var chat_img = chat_ul.getElementsByTagName('img'); send_btn.onclick = function () { if (send_txt.value == '') { alert("请不要惜字如金"); } else { chat_ul.innerHTML += '<li><img src="../img/img_24.jpg"><span>' + send_txt.value + '</span>'; now++; if (num==0) { chat_span[now].className = 'spanright'; chat_img[now].className = 'imgright'; } else { chat_span[now].className = 'spanleft'; chat_img[now].className = 'imgleft'; } send_txt.value = ''; // 内容过多时,将滚动条放置到最底端 /*contentcontent.scrollTop = content.scrollHeight;*/ } } }
num 消息显示在左边还是右边，根据后台请求来操作
