没有 jquery 试试这个:

<script type="text/javascript">
function toggle(me, other) {
    me.setAttribute('style', 'display: none');
    var otherElement = document.getElementById(other);
    otherElement.removeAttribute('style');

    if(otherElement.tagName.toLowerCase() === 'select') {
        myValue = me.getAttribute('value');
        for(var n = 0; n < otherElement.options.length; n++) {
            if(otherElement.options[n].getAttribute('value') == myValue) {
                otherElement.options[n].select;
                break;
            }
        }
    }
    else {
        myValue = me.options[me.options.selectedIndex].getAttribute('value');
        otherElement.value = myValue;
    }
}
</script>

<input onclick="toggle(this, 'the_select');" id="the_input" />
<select onchange="toggle(this, 'the_input');" id="the_select"  style="display:none">
    <option value="male">male</option>
    <option value="female">female</option>
    <option value="alien">alien</option>
</select>

用 jquery 试试这个

<script type="text/javascript">

function initToggle(select, input) {
    var s = jQuery('#' + select);
    var i = jQuery('#' + input);
    i.click(function(){
        i.hide();
        s.show().val(i.val());
    });
    s.change(function(){
        s.hide();
        i.show().val(s.val());
    });

}

</script>

<input id="the_input" />
<select id="the_select"  style="display:none">
    <option value="male">male</option>
    <option value="female">female</option>
    <option value="alien">alien</option>
</select>
<script type="text/javascript">
    jQuery(function(){
        initToggle('the_select', 'the_input');
    });
</script>

或者使用 jquery 和动态

<script type="text/javascript">

function initToggle(input, options) {
    var s = jQuery('<select />')
        .hide();
    for(var n = 0; n < options.length; n++) {
        s.append(jQuery('<option/>')
            .attr('option', options[n])
            .html(options[n]));
    }
    var i = jQuery('#' + input).after(s);
    var conf = function(a, b, method) {
        a.unbind(method).bind(method, function(){
            a.hide();
            b.show().val(a.val());
        });

    }
    conf(i, s, 'click');
    conf(s, i, 'change');       
}

</script>

<input id="the_input" />
<script type="text/javascript">
    jQuery(function(){
        initToggle('the_input', ['male', 'female', 'alien']);
    });
</script>
