如何显示与下拉列表中单击的项目相关的数据。 [英] How to display data that is relevant to the item clicked in the dropdown list.

问题描述

我想显示与使用C＃在下拉列表中点击的项目相关的数据。例如，我有一个下拉列表项目，如一般评论和评论。页面如下图所示。在下拉列表中选择评论项目时，光标需要指向评论（需要像WORD一样工作。）

不要问我需要写预订申请。准确说明你需要帮助的是什么。



评论：

保持问题尽可能简洁。如果你必须包含代码，请包含最小的代码片段 - 不要转储整个代码库。

Hi,

I would like to display the data that is relevant to the item clicked in the dropdownlist using C#.For Example,I have a dropdownlist items like General comments and Comments.The page looks like as shown below.On selecting the Comments item in the dropdownlist,The cursor need to points the Comments(Need to works like a WORD.)

General comments:

Don''t ask "I need to write a booking application". Specify exactly what it is you need help with.

Comments:
Keep the question as concise as possible. If you have to include code, include the smallest snippet of code you can - do not dump your entire codebase.

推荐答案

它可以使用jquery来完成。

Hi,
it can be accomplished using jquery.

//get all products from DB and save them
  ProductList = new ProductsBLL().GetAllProductsList();


  this.ddl.DataValueField = "Id";
  this.ddl.DataTextField = "ProductName";

  this.ddl.DataSource = ProductList;
  this.ddl.DataBind();

和jquery

and the jquery

（' ＃Main_ddl'）。change（ function （）{
alert（

('#Main_ddl').change(function () { alert(

（' ＃Main_ddl'）。val（））;
}）;

('#Main_ddl').val()); });

现在，我已经使用了警报，你可以使用ajax调用来使用你的更多代码或者建立逻辑。



谢谢

now, where I have used alert, you can use ajax call to go with your further code or to build a logic.

thanks
