javascript改变容器内的字体大小
一段js，定义容器和字体的大小，实现网页容器和字体的自定义大小。
<script type="text/javascript">
<!--
function scaleWidth()
{
var optimalLineLength = "35em";
var extraAccounting = "12em";
var minimumTextHeight = "10px";
var windowWidth = document.body.clientWidth;
var optimalSize = windowWidth / (parseInt(optimalLineLength) + parseInt(extraAccounting));
if (optimalSize >= parseInt(minimumTextHeight))
{
document.body.style.fontSize = optimalSize + "px";
}
else
{
document.body.style.fontSize = parseInt(minimumTextHeight) + "px";
}
return true;
}
function textSize(size)
{
var theContainer = document.getElementById("widthContainer");
var increment = 0.1
var currentSize = parseFloat(document.getElementById("widthContainer").style.fontSize);
if (!currentSize)
{
currentSize = 0.8;
}
if (size == "smaller")
{
theContainer.style.fontSize = (currentSize - increment) + "em";
}
else
{
theContainer.style.fontSize = (currentSize + increment) + "em";
}
return true;
}
-->
</script>
