废话不多说了，直接给大家贴js搜索框文字可删除功能，具体代码如下所示：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JS实现搜索框文字可删除</title> <style> *:focus {outline: none; } body {width: 400px;margin: 100px auto;} #topsearch {height: 33px;} #topsearch .input {border: 1px solid #77c03a;height: 100%;} #topsearch .input .clear {width: 30px;height: 35px;line-height: 30px;text-align: center;padding-right: 10px;visibility: hidden;opacity: 0.8;color: gray;} #topsearch input[type=text] {height:20px;width: 250px;border: none;padding: 5px;} #topsearch div {float: left;} #topsearch button {width: 100px;height: 35px;background: #77c03a;color: #fff;border: none;} </style> </head> <body> <div> <div><input type="text"><span>×</span></div> <button type="button">Search</button> </div> <script> document.getElementById("search").addEventListener("keyup", function() { if (this.value.length > 0) { document.getElementById("delete").style.visibility = "visible"; document.getElementById("delete").onclick = function() { document.getElementById("search").value = ""; } } else { document.getElementById("delete").style.visibility = "hidden"; } }); </script> </body> </html>
