This article describes the method of simply adjusting the font size of web pages by JS. Share it for your reference, as follows:
//var tgs = new Array('div','td','tr');
var tgs = new Array('td','tr');
//Specify spectrum of different font sizes:
//var szs = new Array( 'xx-small','x-small','small','medium','large','x-large','xx-large' );
var szs = new Array( '10px','12px','14px','16px','18px','20px','22px' );
var startSz = 2;
function tsize( trgt,inc ) {
if (!)
{
return
}
var d = document,cEl = null,sz = startSz,i,j,cTags;
//sz += inc;
sz = inc;
if ( sz < 0 )
{
sz = 0;
}
if ( sz > 6 )
{
sz = 6;
}
startSz = sz;
if ( !( cEl = ( trgt ) ) ) cEl = ( trgt )[ 0 ];
= szs[ sz ];
for ( i = 0 ; i < ; i++ )
{
cTags = ( tgs[ i ] );
for ( j = 0 ; j < ; j++ )
{
cTags[ j ]. = szs[ sz ];
}
}
}
How to use:
<td width="13">
<a href="javascript:tsize('body',0)">
<img src="../image/"
name="fsize1" width="18" height="14" border="0"
onMouseOver="MM_swapImage('fsize1','','../image/',1)"
onMouseOut="MM_swapImgRestore()"></a>
</td>
