Contoh dalam artikel ini menerangkan kaedah melaksanakan warna selang Jadual dan penyerlahan pemilihan (dan penukaran data dinamik) menggunakan javascript. Kongsikan dengan semua orang untuk rujukan anda. Kaedah pelaksanaan khusus adalah seperti berikut:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Table间隔色以及选择高亮(和动态切换数据)</title> <script type="text/javascript"> var Datas1 = { "李莫": "毕业于清华大学", "周平": "毕业于北京大学", "罗达": "毕业于哈尔滨大学", "郑朵": "毕业于河南大学", "王天": "毕业于湖南大学" }; var Datas2 = { "脚本之家": "http://www.jb51.net", "搜狐网": "http://www.souhu.com", "CSDN程序员开发网站": "http://www.csdn.net", "百度": "http://www.baidu.com", "网易": "http://www.163.com" }; function ToggleData() { var btn = document.getElementById("btnToggle"); if (btn.value == "数据1") { loadData(Datas1, "数据2"); } else { loadData(Datas2, "数据1"); } } function loadData(Datas,btnValue) { var tblMain = document.getElementById("tblMain"); //清空table数据 var trs = tblMain.getElementsByTagName("tr"); var trsLen = trs.length; //必须先把trs的长度存放到一个变量中 for (var i = 0; i < trsLen; i++) { tblMain.deleteRow(0); } var nIndex = 0; for (var key in Datas) { var tr = tblMain.insertRow(-1); tr.onmouseover = trMouseOver; tr.onmouseout = trMouseOut; var td1 = tr.insertCell(-1); td1.innerHTML = key; var td2 = tr.insertCell(-1); td2.innerHTML = Datas[key]; if (nIndex % 2 == 0) { //设置间隔色 tr.style.background = "yellow"; } else { tr.style.background = "white"; } nIndex++; } var btn = document.getElementById("btnToggle"); btn.value = btnValue; } function trMouseOver() { var tblMain = document.getElementById("tblMain"); //清空数据 var trs = tblMain.getElementsByTagName("tr"); for (var i = 0; i < trs.length; i++) { if (this == trs[i]) { trs[i].style.background = "green"; } } } function trMouseOut() { var tblMain = document.getElementById("tblMain"); var trs = tblMain.getElementsByTagName("tr"); for (var i = 0; i < trs.length; i++) { if (i % 2 ==0) { trs[i].style.background = "yellow"; } else { trs[i].style.background = "white"; } } } function iniEvent() { loadData(Datas1, "数据2"); } </script> </head> <body onload="iniEvent()"> <table id="tblMain"> <tbody></tbody> </table> <input type ="button" id="btnToggle" value="数据2" onclick="ToggleData()" /> </body> </html>
Saya harap artikel ini akan membantu reka bentuk pengaturcaraan JavaScript semua orang.
