You can use     document getElementById  theForm   submit         but don t replace the innerHTML  You could hide the form and then insert a processing    span which will appear in its place   var form   document getElementById  theForm     form style display    none    var processing   document createElement  span     processing appendChild document createTextNode  processing          form parentNode insertBefore processing  form
