Answer 1

If there is only one input with the class .school_name , use this

$("#save_newsection").click(function() {
    var value = $("input.school_name").val();
    // use value
});

If there could be more of them throughout the document use this:

$("#save_newsection").click(function() {
    var value = $(".school_form_submit .school_name").val();
    // use value
});

 $("#save_newsection").click(function() { var value = $(".school_form_submit .school_name").val(); alert(value); });
