Bypassing blamk fields

I have one form, many text input types which allow users to to do a search
of my image database. It is possible, with this form to leave certain text
fields blank.
Is there a way to use javascipt to bypass blank fields in a search? I dont
want to take up processor time or see the blank name/value pairs in the
query string. Anyone know what i mean?

Just use a conditional. If the javascript is generating an URL query
string by looping through inputs, it may look something like this:

var myURL = "http://www.mywebsite.com/myformhandler.php?";
var myInputs =
document.getElementById("myForm").getElementsByTag Name("input");
for(i=0;i<myInputs.length;i++) {
myURL += (myInputs[i].value=="") ? "" : myInputs[i].name + "=" +
myInputs[i].value + "&";
}
myURL = encodeURI(myURL);
window.location.href = myURL;
