本文實例講述了js實現人才網站職位選擇功能的方法。分享給大家供大家參考。具體如下：
這是一個比較實用的JS列表框功能，像很多人才網站的職位選擇功能一樣，從左側列表框選擇后會添加至右側列表框，還可以上下移動、增刪內容，感覺非常有用的代碼。
運行效果如下圖所示：
在線演示地址如下：

具體代碼如下：
<html><head><title>人才網站的職位選擇功能代碼</title><script>function move(fbox,tbox) {var i = 0;if(fbox.value != "") {var no = new Option();no.value = fbox.value;no.text = fbox.value;tbox.options[tbox.options.length] = no;fbox.value = ""; }}function remove(box) {for(var i=0; i<box.options.length; i++) {if(box.options[i].selected && box.options[i] != "") {box.options[i].value = "";box.options[i].text = ""; }}BumpUp(box);} function BumpUp(abox) {for(var i = 0; i < abox.options.length; i++) {if(abox.options[i].value == "") {for(var j = i; j < abox.options.length - 1; j++) {abox.options[j].value = abox.options[j + 1].value;abox.options[j].text = abox.options[j + 1].text;}var ln = i;break; }}if(ln < abox.options.length) {abox.options.length -= 1;BumpUp(abox); }}function Moveup(dbox) {for(var i = 0; i < dbox.options.length; i++) {if (dbox.options[i].selected && dbox.options[i] != "" && dbox.options[i] != dbox.options[0]) {var tmpval = dbox.options[i].value;var tmpval2 = dbox.options[i].text;dbox.options[i].value = dbox.options[i - 1].value;dbox.options[i].text = dbox.options[i - 1].textdbox.options[i-1].value = tmpval;dbox.options[i-1].text = tmpval2; } }}function Movedown(ebox) {for(var i = 0; i < ebox.options.length; i++) {if (ebox.options[i].selected && ebox.options[i] != "" && ebox.options[i+1] != ebox.options[ebox.options.length]) {var tmpval = ebox.options[i].value;var tmpval2 = ebox.options[i].text;ebox.options[i].value = ebox.options[i+1].value;ebox.options[i].text = ebox.options[i+1].textebox.options[i+1].value = tmpval;ebox.options[i+1].text = tmpval2; } }}</script></head><body><form ACTION="" METHOD="POST"> <table align="center"> <tr><td><input type="text" name="list1" value=""></td><td><input type="button" value="添加" onclick="move(this.form.list1,this.form.list2)" name="B1"><br><input type="button" value="刪除" onclick="remove(this.form.list2)" name="B2"><br><br><input type="button" value="上移" onclick="Moveup(this.form.list2)" name="B3"><br><input type="button" value="下移" onclick="Movedown(this.form.list2)" name="B4"></td><td><select multiple size=7 name="list2"><option value="one">ASP</option><option value="two">PHP</option><option value="three">ASP.NET</option><option value="four">DELPHI</option><option value="five">VB</option><option value="six">AJAX</option></select></td></tr></table></form></body></html>希望本文所述對大家的javascript程序設計有所幫助。
