hey guys, I have to create a scientific calculator using javascript and I am wondering how I can make it so that the equals box (box that displays the answer) cannot be manually cleared with the mouse cursor.



thanks!

That's the HTML to make a disabled input. If you don't know where to place something like that in the markup section of your code, you should probably learn HTML before attempting javascript.

<input type="text" disabled="true">



<input type="text" readonly>

would be better as then the result will not be greyed out.

Also ="true" is invalid HTML. You either specify disabled by itself to disable a field in HTML or use disabled="disabled" for XHTML.
