Answer 1

The code below works. As others have mentioned, you've misspelled document . Also the simplest way to achieve what you want is with setInterval , and unquoted function name.

var col=0;
function changeMarqueeColor() 
{
    if(col==0)
    {
        document.getElementById("thakan").style.color="red";
        col=1;
    }
    else
    {
        document.getElementById("thakan").style.color="blue";
        col=0;
    }
}
setInterval(changeMarqueeColor,500);

您拼写错误的“文档”，而写了“ documrnt”。
