DarkHorizon Posted August 3, 2006 Share Posted August 3, 2006 Hi,i dont know if this can be done but here goes:i have a form with two inputs. One is a checkbox and one is a text field. If the check box is checked, the text field gets greyed-out, disallowing user input to that field. If the check box is [i]not[/i] checked then the user can fill in the text field instead.is this possible with a bit of javascript?cheersDH Link to comment https://forums.phpfreaks.com/topic/16432-help-with-html-form/ Share on other sites More sharing options...
