[Koha] Stopwords with Zebra using Javascript

3 May 2013

      Good morning,

I maybe have a temporary solution about the stopwords and zebra.
You can use this following javascript and put in the global system
preferences of Koha.

The only thing you have to do is to paste the code in the "intranetuserjs"
and "opacuserjs" preferences.

Here is the code between the two lines with only 4 words. You can add as
many as you want.
-------------------
function removeStopwords(query) {
	var stopwords = new Array("A","ABOUT","ABOVE","ALL");
	var string = "";
	for ( var i = 0; i < stopwords.length; i++) {
		for ( var j = 0; j < query.length; j++) {
			if (query[j].toLowerCase() == stopwords[i].toLowerCase()) {
				query[j] = "";
			}
		}
	}
	for ( var i = 0; i < query.length; i++) {
		if (query[i] != "") {
			string += query[i] + " ";
		}
	}
	string = string.substring(0, string.length - 1);
	return string;
}

$(document).ready(function() {
	var number_form = $('form').length;
	if (number_form > 2){
		number_form = 1;
	}
	$('form').eq(number_form -1).submit(function(){
		var number_q = $("[name='q']").length;
		for (var i = 0; i < number_q; i++){
			$("[name='q']").eq(i).prop('value',
removeStopwords($("[name='q']").eq(i).val().split(' ')));
		}
	});
});
-------------------

Cheers
