推荐答案

选择列表使用 onchange 而不是 onclick.

use onchange instead of onclick for select lists.

<select name="history" id="history" onchange="historyChanged(this);">
 <option value="history1">history 1</option>
 <option value="history2">history 2</option>
 <option value="clearhistory">Clear History</option>
</select>

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">

function historyChanged() {
    var historySelectList = $('select#history');
    var selectedValue = $('option:selected', historySelectList).val();

    alert(selectedValue);

    if (selectedValue == 'clearHistory') {
        historySelectList.form.submit();
    }
}

$(function() {
    alert('my alert');
    $('select#history').change(historyChanged);
});

</script>
