这是一个经常发生的主题:创建带有复选框的下拉列表。
但是我仍然有一个常见错误: “未捕获的TypeError:$(...)。multiSelect不是函数”
以下是渲染HTML:
<head>
<title>Listing</title>

<script src="http://cdn.rawgit.com/davidstutz/bootstrap-multiselect/master/dist/js/bootstrap-multiselect.js"
type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('[id*=lstFruits]').multiSelect({
includeSelectAllOption: true
});
$("#Button1").click(function () {
alert($(".multiselect-selected-text").html());
});
});
</script>
我尝试同时使用“ multiSelect”和“ multiselect”。
这是列表框:
<td>
<asp:ListBox ID="lstFruits" runat="server" SelectionMode="Multiple">
<asp:ListItem Text="Mango" Value="1" />
<asp:ListItem Text="Apple" Value="2" />
<asp:ListItem Text="Banana" Value="3" />
<asp:ListItem Text="Guava" Value="4" />
<asp:ListItem Text="Orange" Value="5" />
</asp:ListBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Submit" />
</td>
后面的代码也已经完成并且可以工作:
protected void Submit(object sender, EventArgs e)
{
string message = string.Empty;
foreach (ListItem item in lstFruits.Items)
{
if (item.Selected)
{
message += item.Text + " " + item.Value + "\\n";
}
}
ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", "alert('" + message + "');", true);
}
问题:我的视图仍然呈现一个列表框,而不是带有复选框的下拉列表,另外,当我单击一个项目时,它会自动刷新并显示加载符号(次要问题)
我想念什么?为什么我看不到教程中的下拉列表?
