每天一个jquery插件-做搜索历史,供大家参考,具体内容如下
效果如下
代码部分
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>做搜索历史</title> <script src="js/jquery-3.4.1.min.js"></script> <style> *{ margin: 0px; padding: 0px; } #searchbox{ /* border: 1px solid lightgray; */ height: 40px; width: 720px; position: relative; } #searchinput{ border: 1px solid lightgray; border-radius: 5px 0px 0px 5px; height: 28px; position: absolute; right: 45px; top: 5px; left: 5px; width: 670px; outline: none; text-indent: 12px; font-size: 12px; color: gray; } #searchinput:focus{ border-color: rgb(252,25,68); } #searchinput:focus~#morebox{ display:flex; } #searchbtn{ height: 30px; width: 40px; border: none; border-radius: 0px 5px 5px 0px; background-color: rgb(252,25,68); position: absolute; right: 5px; top: 5px; display: flex; justify-content: center; align-items: center; cursor: pointer; } #searchbtn img{ width: 25px; height: 25px; } #morebox{ border: 1px solid lightgray; position: absolute; top: 40px; left: 5px; right: 5px; height: 370px; z-index: 7; border-radius: 2px; display: flex; display: none; } #push{ flex: 1; /* border: 1px solid lightgray; */ position: relative; } #history{ /* display: none; */ flex: 1; /* border: 1px solid lightgray; */ position: relative; } .head{ position: absolute; top: 0px; width: 100%; height: 30px; border-bottom: 1px solid lightgray; font-size: 12px; display: flex; align-items: center; text-indent: 12px; color: rgb(252,85,49); } .main{ position: absolute; top: 30px; width: 100%; bottom: 0px; overflow-x:hidden; overflow-y: auto; } .item{ font-size: 12px; height: 30px; display: flex; align-items: center; text-indent: 12px; cursor: pointer; } .item:hover{ background-color: lightgray; } </style> </head> <body> <div id="searchbox"> <input id="searchinput" placeholder="c一下" /> <button id="searchbtn"><img src="img/sc.png"></button> <div id="morebox"> <div id="history"> <div class="head">搜索历史</div> <div class="main"></div> </div> <div id="push"> <div class="head">热门推荐</div> <div class="main"> <div class="item">微软终于对JDK下手了</div> <div class="item">小米隔空充电技术</div> <div class="item">Linux常用命令大全</div> <div class="item">阿飞超努力又水文了</div> <div class="item">每天学一个jquery插件竟然没有插件!究竟是道德的沦丧,还是人性的扭曲</div> </div> </div> </div> </div> </body> </html> <script> $(document).ready(function(){ //每次点击搜索就假如缓存之中 // $(".item").click(function(){ var str = $(this).text(); $("#searchinput").val(str) }) // localStorage["history"] = '[]'//清除一下缓存; drawhistory(); $("#searchbtn").click(function(){ var str = $("#searchinput").val(); if(str&&str!=""){ var arr = getSession(); arr.push(str); localStorage["history"] = JSON.stringify(arr); drawhistory(); } }) getSession(); //根据缓存找到历史,然后生成搜索历史 function drawhistory(){ var arr = getSession(); $("#history .main .item").remove(); arr.forEach(item=>{ var $item = $("<div class='item'>"+item+"</div>"); $item.appendTo($("#history .main")); }) } //获得缓存 function getSession(){ var ses = localStorage["history"]; var arr = ses==undefined?[]:JSON.parse(ses); return arr; } }) </script>
思路解释
1、布局是个硬伤,我也不知道我这个布局是不是最合适的,不过看着没毛病
2、然后历史部分就是存到localStorage里面,在合适的动作的地方处理成对应的效果放回dom里面
