如果选到右边，是无法获取到值的，必须要点击一次，选中了才能获取到，怎么让右边的默认能获取值
sortitems = 1; // Automatically sort items within lists? (1 or 0)<br />
function move(fbox,tbox) {<br />
for(var i=0; i<fbox.options.length; i++) {<br />
if(fbox.options[i].selected && fbox.options[i].value != "") {<br />
var no = new Option();<br />
no.value = fbox.options[i].value;<br />
no.text = fbox.options[i].text;<br />
tbox.options[tbox.options.length] = no;<br />
fbox.options[i].value = "";<br />
fbox.options[i].text = "";<br />
}<br />
}<br />
BumpUp(fbox);<br />
if (sortitems) SortD(tbox);<br />
}<br />
function BumpUp(box) {<br />
for(var i=0; i<box.options.length; i++) {<br />
if(box.options[i].value == "") {<br />

box.options[j].value = box.options[j+1].value;<br />

}<br />
var ln = i;<br />
break;<br />
}<br />
}<br />
if(ln < box.options.length) {<br />
box.options.length -= 1;<br />
BumpUp(box);<br />
}<br />
}<br />
function SortD(box) {<br />
var temp_opts = new Array();<br />
var temp = new Object();<br />
