There are several methods to detect a browser in JavaScript. One is using the userAgent property.






Example using the userAgent property

code:





<script type="text/javascript">

if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 )
{
alert('Opera');
}
else if(navigator.userAgent.indexOf("Chrome") != -1 )
{
alert('Chrome');
}
else if(navigator.userAgent.indexOf("Safari") != -1)
{
alert('Safari');
}
else if(navigator.userAgent.indexOf("Firefox") != -1 )
{
alert('Firefox');
}
else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true ))
{
alert('IE');
}
else
{
alert('unknown');
}
</script>
