Hi Guys !!!<\/p>\n
My name is Elcio Abrah\u00e3o and I m an University Teacher in S\u00e3o Paulo – Brazil.<\/p>\n
I m using HTML5 to teach programing for my students the form did not change the output value when I add a field type “radio” to the “for” attribute. Is this a project specification or this is a bug ??<\/p>\n
Important: I wish did not to use Javascript in other place except on the “oninput” attribute.<\/p>\n
This is the test code:<\/p>\n
<!DOCTYPE html>
\n<html>
\n<head>
\n<title>Regra de 3 Simples<\/title>
\n<\/head>
\n<body>
\n<h1>C\u00e1lculo Gen\u00e9rico de Regra de 3 Simples<\/h1><br\/><br\/>
\n<form name=”form1″ oninput=”if(document.form1.tipo1.checked==true){
\nx.value = parseFloat(v2.value)*parseFloat(v3.value)\/parseFloat(v1.value)
\n}else{
\nx.value = parseFloat(v1.value)*parseFloat(v2.value)\/parseFloat(v3.value)
\n}”>
\n<h2>Escolha tipo da regra de tr\u00eas simples<\/h2>
\n<input type=”radio” name=”tipo” id=”tipo1″ value=”1″>Diretamente Proporcional<br\/><br\/>
\n<input type=”radio” name=”tipo” id=”tipo2″ value=”2″>Inversamente Proporcional<br\/><br\/>
\n<br\/><br\/>
\n<table border=”1″>
\n<tr><th>Grandeza 1<\/th><th>Grandeza 2<\/th><\/tr>
\n<tr><td><input type=”number” id=”v1″ value=”0″ \/>
\n<\/td><td><input type=”number” id=”v2″ value=”0″ \/>
\n<\/td><\/tr><tr><td><input type=”number” id=”v3″ value=”0″ \/><\/td>
\n<td><output name=”x” for=”v1 v2 v3 tipo”><\/output><\/tr>
\n<\/table>
\n<\/form>
\n<\/body>
\n<\/html><\/p>\n
I just tried to change the calculation when the user check other radio button. I tested on Firefox and Chrome but I must change some “number” type field to get the calculation changed…<\/p>\n
Could you help me ?<\/p>\n
Thanks\u00a0 !!!<\/p>\n
Best Regards,<\/p>\n
