document.forms [0]在调试模式下没有任何元素 [英] document.forms[0] has no elements in debug mode

问题描述

我是ASP.NET的新手，遇到这样的问题.

我有一张桌子的表格.我在其中一个图像中.我想在按钮单击事件上动态更改此设置.我有一个javascript函数可以做到这一点:

Hi,
I am new to ASP.NET and has an issue like this.

I have a form with a table. I have an image in in one of the . I want to change this dynamically on a button click event. I have a javascript function to do this:

function showGraph(url)
{
    var tdimage = document.getElementById("graphimage");//graphimage is the id of td in the table
    if(tdimage != null)
    {
        tdimage.setAttribute(src, url);
    }
}

但是，当我单击按钮并使用VS2008转到调试视图时，除__EVENTTARGET，__ EVENTARGUMENT和__VIEWSTATE之外，我的窗体中没有其他控件.我添加的表发生了什么事情?

But, when I click on the button and go to the debug view using VS2008, I don''t see any controls in my form except __EVENTTARGET, __EVENTARGUMENT and __VIEWSTATE. What happened to the table that I have added??

推荐答案

您正在查看哪个事件?

您是否尝试过
HttpContext.Current.Request.Forms["id"]

查看您已提交的表单控件.

In which event are you looking at ?

Did you tried
HttpContext.Current.Request.Forms["id"]

to see the form control that you have submitted.
