需要帮助从我的代码后面格式化html

Question

I have the following code snippet, but I'm banging my head up against the wall trying to get the errors out of it.

I'm getting the following design time compile errors:

; expected
The name button does not exist in the current context.

Those same two messages also repeat for the DisplayReceipt.

Here is my code snippet being assigned in my code behind for html.

Can somebody please help me out?

Image_ID = "<input id='" + fuelticket.Image_ID + "' type="button" onclick='" + DisplayReceipt(fuelticket.Image_ID)"'>";

Answer 1

You just need to escape the quotes:

Image_ID = "<input id='" + fuelticket.Image_ID + "' type=\"button\" onclick='DisplayReceipt(" + fuelticket.Image_ID + ")'>";

Or use string.Format() to make things a bit cleaner:

Image_ID = string.Format("<input id='{0}' type=\"button\" onclick='DisplayReceipt({0})'>", fuelticket.Image_ID);

Answer 2

To make it work use the below code:

Image_ID = String.Format("<input id=\"{0}\" type=\"button\" onclick=\"{1}\">", fuelticket.Image_ID, DisplayReceipt(fuelticket.Image_ID));

The above looks more clear and optionally you can also use @ for the string so you don't have to escape any special characters.

Image_ID = String.Format(@"<input id="{0}" type="button" onclick="DisplayReceipt({0})">", fuelticket.Image_ID));
