Apply onclick function only if text entered??

[Mike Weathery]

Hi all

I am using the following function in a text entry box:

function goToTV() {
location.href="http://www.tvguide.com" + "/search/index.aspx?keyword=" +
document.search.q.value;
return false;
}

E.g. if the user types in "Lost" then clicks 'TV', it sends them to the URL:
http://www.tvguide.com/search/index.aspx?keyword=Lost

However sometimes I want people to just be able to click TV without typing a
search keyword, but this causes problems as the target site does not
understand
http://www.tvguide.com/search/index.aspx?keyword=

In that case I want it just to go to
http://www.tvguide.com


Q: Is there a way to make the js only apply the '+
"/search/index.aspx?keyword=" + document.search.q.value;' part if there is
text entered in q?

E.g. location.href="http://www.tvguide.com" + ONLY IF Q CONTAINS TEXT THEN
ADD "/search/index.aspx?keyword=" + document.search.q.value;

Thanks in advance for any simple mod to my above js that can do this.

try like this:
function goToTV() {
if (document.search.q.value != "")
{
location.href="http://www.tvguide.com" +
"/search/index.aspx?keyword=" +
document.search.q.value;
}
else
{
location.href="http://www.tvguide.com" ;
}
return false;

}

try like this:
function goToTV() {
if (document.search.q.value != "")
{
location.href="http://www.tvguide.com" +
"/search/index.aspx?keyword=" +
document.search.q.value;
}
else
{
location.href="http://www.tvguide.com" ;
}
return false;

}

Hi you

I am using the following function in a text entry box:

function goToTV() {
var loc = document.search.q.value;
loc = loc!=''? "/search/index.aspx?keyword="+loc : '/';
location.href="http://www.tvguide.com" + loc;
return false; // this last not useful
}
