If you want this on javascript try the below on the onclick event of the button, (OnClientClick, if it is a Server Side button)
func(document.getElementById('MY_TEXTBOX').value)If you want the above in ASP.NET, double click button, it will take you to the code behind, where you can try the below code in the Button Click event,
func(MY_TEXTBOX.Text);Here MY_TEXTBOX is the ID of the textbox you mentioned

document.getElementById returns an object. How will this work in your example?

First, it isn't a very smart idea to try executing arbitrary code entered from a textbox. If you want to do this on the client-side you need to use the eval function. http://www.w3schools.com/jsref/jsref_eval.asp[^] On the server-side you can try using CodeDOM http://msdn2.microsoft.com/en-us/library/y2k85ax6.aspx[^] However, it is VERY, VERY dangerous to try compiling code input from a textbox. Don't even think about it, try something else.

It should be
func(document.getElementById('MY_TEXTBOX').value);Thanks Marks for pointing out.

I don't understand what you are asking for here.:confused: Do you want something like; func("Console.WriteLine("Hello, World");" ) which causes "Hello, World" to be written to a console window?:confused:

i want to say the textbox will be used to write code statements and clicking the button will execute the statement written in the textbox Example; if in the textbox i write MessageBox.Show("Hello"); then clicking the button executes the statement in the textbox in this case display a messagebox

Then read my previous response about CodeDOM, and the warning that this is VERY dangerous thing, don't do it, think of another way.
