使用javascript函数从C#代码后面将ListBoxItem添加到ListBox [英] Add ListBoxItem to ListBox from C# code behind using a javascript function
问题描述
我有一个使用ASP.Net编写的页面(C#)
我有一个不是服务器控件但只是一个锚点的按钮(
< a href = java<! - no - > script:Add_Button_Click > 添加< / a >
)。
菜单代码如下所示:
< pre lang =HTML> < ul >
< li > ; < a href = java< ! - no - >脚本:Add_Button_Click('someString'); > 为ASP.Net ListBox添加值< / a > < / li >
< / ul >
Add_Button_Click(JavaScript):
< script 类型 = text / javascript > ;
function Add_Button_Click(someStringValue){
}
< / script >
Add_Button_Click(C#Code Behind):
public static void Add_Button_Click( string someValue)
{
ListBox box = Page.FindControl( ListBox1) as ListBox; // 我不太确定这部分是否有效,但这是我到目前为止所做的。
}
在我的页面代码背后我需要做两件事:
1.)打电话给C#fu从JavaScript代码开始。
2.)在从JavaScript调用的C#函数中,我需要将一个ListBoxItem添加到驻留在我页面上的ASP.Net ListBox服务器控件中。
我在网上搜索过但似乎无法找到让这些东西正常工作的方法。
请用示例代码告诉我你们怎么做这个,谢谢!!!
看看这个样本。

I have a page that's written using ASP.Net (C#)
I have a button that is NOT a server control but is just an anchor (
<a href="java<!-- no -->script:Add_Button_Click">Add</a>
).
The menu code looks like this:
<ul>
<li><a href="java<!-- no -->script:Add_Button_Click('someString');">Add Value To ASP.Net ListBox</a></li>
</ul>
The "Add_Button_Click" (JavaScript):
<script type="text/javascript">
function Add_Button_Click(someStringValue) {
}
</script>
The "Add_Button_Click" (C# Code Behind):
public static void Add_Button_Click(string someValue)
{
ListBox box = Page.FindControl("ListBox1") as ListBox;//I'm not too sure if this part works but it's what I have so far.
}
In my page's Code Behind I need to be able to do two things:
1.) Call a C# function from the JavaScript code.
2.) In the C# function that's being called from JavaScript I need to add a ListBoxItem to an ASP.Net ListBox Server Control that resides on my page.
I've searched the web but can't seem to find a way to make any of these things work correctly.
Please show/tell me with example code how you guys would go about doing this, Thanks!!!
Look on this sample.
