工作学习 / IT技术讨论 / ASP.net高手请进我想在网页里放一个固定的窗口，这个窗口不做别的，只用来显示其它的网页用，比如放新浪或者网易．但在窗口里放的网页需要是动态的，我需要按一个键窗口里显示新浪，按另外一个键窗口里显示网易，也就是说我要用程序来设置此窗口的URL．请教各位高手，在asp.net里是否提供这样的控件来实现此功能？多谢！

多谢！不过iframe是client端的，不知asp.net是否提供server端的控件？这样实现起来会方便许多（因为url的生成逻辑比较复杂）

你那几个键作成提交form不就行啦? target都在那个frame里面...

Option 1: web user control; Option 2: Reload page with dynamically configured request string each time you want change. (The first option seems to be easier. )

多谢！第一种方案比较好，不过不知道如何做这样的user control． ASP.net的image control都能设置url,为什么.net不提供能实现此功能的control呢？用iframe就是用的第二种的方案，我知道能行得通，不过调了一整天都没有调出来，不知道问题出在哪．

做一个空白的.ascx, 在Page_Load里面写Response.Redirect("http://XXXX"), 当然得自己生成URL, 然后把它拖进你的网页...

这个方案看起来比用下面的用ATTRIBUTE 更简单, 有没有DX 有雅兴试验一下行不行. 我现在没有VS, 就免啦.

这个办法把页面分成了两个文件, 从程序的重复使用角度说是可取的, 但是对于目前这个问题, 组件里面只有一行程序, 好象用不着这样...

yes, using attribute is much easier. Before I just didn't know I could set those HTML elements' attributes using .NET. Because of this, in fact, we can consider HTML elements as web control too.

这个HTML除了FRAME还有其它方法吗? 楼主已经说了不想用FRAME.

I do not particulary hate to use frame or iframe. It is just because they make programming much more difficult. After all, I need to get those dynamic URL generated by server and database,
-jeff2ll(jeff);

(#2086313@0)

你这个动态URL是每次load page更新一次，还是经常更新？

almost every button in the webpage has to change the URL dynamically

Great!!!!!! Thank you very much .....This is what exactly what I want.I have believed microsoft must have provided something to solve such question

这里关键的地方就是要把client side的control 在code behind里面定义出来，这样就可以为所欲为了，基本上。：）

but iframe or frame are only good when you already get the URL in client site. BTW, I do not think it is a trap of Microsoft. If you wanna such have website with such a function, it won't be easy for any other programming tools either.

using javascript plus xmlhttp component plus layer will give you all flexibility

Can you provide an example with what you have mentioned? Thanks.

some hintfunction getpage()
{
var objHTTP = new ActiveXObject("Microsoft.XMLHTTP")
objHTTP.Open('GET',http://www.yahoo.com',false)
objHTTP.Send()
var txt= objHTTP.ResponseText
...
}
This will get content from site,then write the txt into layer you created, if you make url to be variable, you will get page dynamically when you click button
..

the example you gave is not a solution. It is easy because you use JavaScript and define the URLs in the program in the client site already. How do you get those URLs if they are in the database?

You can pass the value from database to javascript function.

I don't like some ASP dot Net developer, wonder why? not because they don't understamd ASP can output dynamic content, but their attitude, hehe.

well, my attitude is good. I have thanked you, right? :-) BTW, I am not a .net developer. I used to be an Oracle DBA but now I am just a student.I like to ask questions. Your solution just doesn't seem to fit my requirement. exactly. Fortunately, finnally I got the solution I need.

No way.It's impossible to create a server side control acting as a browser.
