结合Response.Write和JavaScript的ASP.NET编程

Question

I am new to ASP.NET. Now I am in the process of modifying some elements in our site. My page has n images displayed. On clicking each images another set of images will be written on the page which is based on the image clicked. So the following code is used.

for i=1 to n
response.write"<img src="&SourceFile&" id="&i&" onClick=func(this)>"
next

And my function code is as follows

newSrc="myweb.com/Images/img1.gif"
function func(x)
{
     switch(parseInt(x.id))
     {
          case 1:x.src=newSrc;
                 break;
      }
 }

when i checked i found the error x is null or not an object. Can you please help me spot the errors...

Answer 1

you need to to this.id

response.write"<img src="&SourceFile&" id='"&i&"' onClick='func(this.id)'>"

make sure that your function is <script></script> client side
