function createtext(field)
{
var noele = document.getElementsByName(‘matname’);
var cnt = 0;
for (var i=0;i<noele.options.length;i++){
if(noele[i].selected){
cnt++;
}
}
alert(cnt);
}

Could anybody tell where I am going wrong with the above code. I am not getting the output. I want to alert how to options are selected in a select.

The getElementsByName() function returns a NodeList, not a single Node. So you need to use noele[0] to reference your element.

A better way would be to specify an ID for the element and use getElementById(), which returns a single node. You should need an ID anyway, in order to associate a <label> with the <select>.
