A simple way to switch functions in Js_javascript skills

I estimate that many friends who are learning CSS and JS have also had this experience. When I was doing this JS switch, I thought of a good method and will share it with you immediately. I hope you can take it away

Copy code The code is as follows:

function changeDiv(index)
{
for(var i =0;i<=5;i )
{
if(i == index)
document.getElementById('dv_' i).className="txt1";
else
document.getElementById('dv_' i).className="txt2";
}
}

But you may not be able to see it clearly, so let me put the html It’s posted, let’s take a look,

Copy the code The code is as follows:

< table width="100%" height="616" border="0" align="center" cellpadding="0" cellspacing="5" bgcolor="#FEFDF8" class="border1">
< tr>
