Hola
espero me puedan ayudar. Estoy prgramando microcontrolador que tienen un servidor Web. la programacion es en C. estoy tratando de hacer un formulario dinamico. Un formulario genere el otro. el problema que tengo es al oprimir el boton submit me genera el otro formulario sin importar la valiacion de los campos. No como hacer para que esto no suceda. ya que en C estoy activando el otro formulario. Existe algun script en el cual pueda activar el "for" dependiendo de alguna variable dentro del mismo formmulario? algo asi como un "if"
. Adjunto codigo...espero relamente me puedan ayudar o enviar un codigo o script.
Saludos

" tecla = (document.all) ? e.keyCode : e.which; "// 2
" if (tecla==8) return true;" // 3
" patron = /[1234567890.]/;" // 4
" te = String.fromCharCode(tecla);" // 5
" return patron.test(te);" // 6
"} "
"function validar(){"
"if(formulario.namepv.value == \"\"){"
"alert('Insert Name de PV');"
"}"
