So if i have veriable called "hello" and if i type hello in the inputbox ill display "this works!" else "error". here is something that i tryed to do but is not working for some reason :-/ <script language="javascript" type="text/javascript"> function showAlert() { string1=document.getElementById("x").value; if (string1 = x) { document.write("hello world"); } else{ document.write("error"); } } </script> <p><input name="string1" type="text" id="x" value="string1"></p> <p><input type="button" value="Click here" onClick="showAlert();"></p> Тhanks!
