如何在下拉菜单中获取所选值并将其附加到site_url中？我不知道该怎么做。请指出正确的方向。谢谢。

<form name="filterByDate" method="post">
<h3>Filter Suggestion</h3>&nbsp;
    <select name="year">
        <option value="2013">2013</option>
        <option value="2014">2014</option></select>

    <ul>
        <li><a href="<?php echo site_url("suggestion/filter/1/". HOW TO APPEND SELECTED VALUE HERE ."); ?>">Jan</a></li>
        <li><a href="<?php echo site_url("suggestion/filter/2"); ?>">Feb</a></li>
    </ul>

</form>

我在下面编辑了接受的答案：这是编辑的部分：

 var linksContainer=document.getElementById("linksContainer");
 linksContainer.innerHTML="<li><a href=\"javascript:window.location('<?php echo site_url(); ?>/suggestion/filter/1/"+selval+"');\">January</a>

尝试使用下面的代码：（已对其进行了些微更改）

<html>
<body>
<form name="filterByDate" method="post">
<h3>Filter Suggestion</h3>&nbsp;
    <select name="year" onchange="generateLinks(this);">
        <option value="2013">2013</option>
        <option value="2014">2014</option></select>

    <!-- <ul>
        <li><a href="<?php echo site_url("suggestion/filter/1/". HOW TO APPEND SELECTED VALUE HERE ."); ?>">Jan</a></li>
        <li><a href="<?php echo site_url("suggestion/filter/2"); ?>">Feb</a></li>
    </ul> -->

    <ul id="linksContainer">
    </ul>

</form>

<script type="text/javascript">
function generateLinks(obj){
    var selval=obj[obj.selectedIndex].value;
    var linksContainer=document.getElementById("linksContainer");
    linksContainer.innerHTML="<li><a href=\"javascript:site_url('suggestion/filter/1/"+selval+"');\">Jan</a></li>";
}
</script>
</body>
</html>
