Question

Guest maxxuser

Estou com um problema:quero que o usuario do site digite o tamanho do paragrafo no campo texto (id="cmp") e ao clicar em 'Change font size', o tamanho o texto do 'p1' seja o valor digitado. alguém pode me ajudar a resolver?

<html>

<head>

<script>

function toggle() {

var el = document.getElementById('p1');

if ( el.style.fontFamily != 'Harry P, arial' ) {

el.style.fontFamily = 'Harry P, arial';

}

else {

el.style.fontFamily = 'Time News Roman';

}

}

</script>

<script>function mudabg(){

var mudar

mudar=document.form1.campo.value

document.bgColor = mudar

}

</script>

</script>

<script>function mudatam(){

document.getElementByID('p1').style.fontSize = document.getElementsByID('cmp').value

}

</script>

</head>

<body><form name="form1"><input type="text" id="cmp"></form>

<input type="button" onclick="toggle()" value="Change font" />

<input type="button" onclick="mudatam()" value="Change font size" />

<input type="button" onclick="mudabg()" value="Change bgColor" />

<p id="p1" style="font-size: 2em">This is an example paragraph.</p>

</body>

</html>
