Answer 1

I think you want this as your onchange event:

<select name="search_school" id="search_school" onchange="$('#school_name').val($('#search_school').val())">

When you call val() without a parameter, it fetches the value of the element. If you call it with a parameter like val('some value'); , it sets the value of the element.

Answer 2

If you can, avoid inline event definition on html:

<select name="search_school" id="search_school">
...
</select>
<input type="hidden" name="school_name" id="school_name" />

$(document).ready(function () {
    $('#search_school').change(function () {
        $('#school_name').val($(this).val());
    });
});

Answer 3

You want something like this, I think:

$("#search_school").change(function(){
  $(this).val($("#search_school option:selected").text());
});

Answer 4

要将所选值设置为隐藏控件，您应该：

<select name="search_school" id="search_school"  onchange="$('#school_name').val($('#search_school').val())">

<script type="text/javascript">
    $(document).ready(function() {
        $("#search_school").change(
            function () {
                $('#school_name').attr('value', $("#search_school").val());
            }
        );
    });
</script>
