我有一個選擇框調用'ToLB',它從另一個選擇框中獲取值項目。我需要從'ToLB'中提取這些選定的值並將其打印在標籤上,這就是我如何做的,但顯然它不工作,因爲沒有任何錯誤信息,但沒有打印到標籤上,敬請建議,謝謝! :Javascript +從選擇框中打印值
選擇框:
<select multiple size="8" name="ToLB" style="width: 135px" onblur="javascript:dropValue6(this)">
</select>
標籤:
QMType: <asp:Label ID="destinationQualMemType" runat="server" ></asp:Label >
JavaScript函數:
function dropValue6(source) {
while (source.selectedIndex != -1)
{
if (source.selectedIndex != 0) arSelected.push(source.options[source.selectedIndex].value);
source.options[source.selectedIndex].selected = false;
var i;
for (i = 0; i < arSelected; i++) {
document.getElementById('<%= destinationSpendingType.ClientID %>').innerHTML =
+ "\n" + document.getElementById('<%= destinationSpendingType.ClientID %>').innerHTML = arSelected[i].value;
}
}
}
