代码如下：
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>迷糊网罗</title> <style type="text/css"> * { margin: 0; padding: 0; } form { position: absolute; left: 50%; top: 40%; } form input:nth-child(1) { width: 450px; height: 34px; float: left; font-size: 16px; text-indent: 0.5em; outline: none; box-sizing: border-box; } form input:nth-child(1):focus { border: 1px solid blueviolet; } form input:nth-child(2) { height: 34px; float: left; background: blueviolet; cursor: pointer; width: 80px; letter-spacing: 2px; border: 0; font-size: 14px; line-height: 34px; } #oul { position: absolute; left: 0; top: 34px; background: white; width: 530px; box-shadow: 3px 3px 5px #F3F3F3; border: 1px solid #F3F3F3; box-sizing: border-box; display: none; } #oul li:hover { background: #F3F3F3; cursor: pointer; } </style> </head> <body> <form action="" method=""> <input type="" value="" /> <input type="button" value="迷糊网罗" /> <ul> </ul> </form> <script type="text/javascript"> //https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=&cb=&_=1497256697565 //位置调整 习惯就好.. var fm = document.getElementsByTagName('form')[0]; var x = fm.offsetWidth; var y = fm.offsetHeight; fm.style.marginLeft = -x / 2 + 'px'; fm.style.marginTop = -y / 2 + 'px'; //获取操作元素 var txt = document.getElementById("txt"); var oul = document.getElementById("oul"); //动态创建js脚本 txt.onkeyup = function(ev) { var value = this.value; var newscript = document.createElement("script"); newscript.src = 'https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=' + value + '&cb=walk&_=' + Math.random(); newscript.type = 'text/javascript'; document.body.appendChild(newscript); } //设置回调函数 function walk(walkJson) { if(txt.value == 0) { oul.style.display = 'none'; } else { oul.style.display = 'block'; oul.innerHTML = ''; if(walkJson.s.length <= 10) { for(var i = 0; i < walkJson.s.length; i++) { var oli = document.createElement('li'); oli.style.height = 25 + 'px'; oli.style.width = 100 + '%'; oli.style.lineHeight = 25 + 'px'; oli.style.textIndent = 9 + 'px'; oli.style.listStyle = 'none'; oli.innerHTML = walkJson.s[i]; oul.appendChild(oli); } } else { for(var i = 0; i < 10; i++) { var oli = document.createElement('li'); oli.style.height = 25 + 'px'; oli.style.width = 100 + '%'; oli.style.lineHeight = 25 + 'px'; oli.style.textIndent = 9 + 'px'; oli.style.listStyle = 'none'; oli.innerHTML = walkJson.s[i]; oul.appendChild(oli); } } } } </script> </body> </html>
