左右选择
function moveOption(e1, e2) {
try {
for (var i = 0; i < e1.options.length; i++) {
if (e1.options[i].selected) {
var e = e1.options[i];
e2.options.add(new Option(e.text, e.value));
e1.remove(i);
ii = i - 1
}
}
document.myform.city.value = getvalue(document.myform.list2);
} catch (e) {
}
}
function getvalue(geto) {
var allvalue = "";
for (var i = 0; i < geto.options.length; i++) {
allvalue += geto.options[i].value + ",";
}
return allvalue;
}
function changepos(obj, index) {
if (index == -1) {
if (obj.selectedIndex > 0) {
obj.options(obj.selectedIndex).swapNode(
obj.options(obj.selectedIndex - 1))
}
} else if (index == 1) {
if (obj.selectedIndex < obj.options.length - 1) {
obj.options(obj.selectedIndex).swapNode(
obj.options(obj.selectedIndex + 1))
}
}
}
获取值: var zhi = document.myform.city.value; 通过ajax 传向后台
后台以字符串接收 String channelString = request.getParameter("channel");
String[] channelArray = channelString.split(",");
for (int i = 0; i < channelArray.length; i++) {
String string = channelArray[i];//分别获取到值
}
双向选择,通常用于给多向配置
