選擇傳遞到鏈接的下拉選項ahref

Question

如何將我的選項傳遞給URL參數？

選擇代碼：

echo "<select id=\"reasoncode\" name=\"reasoncode[$transnum]\"><option value=\"$ot_reasoncode\" default>$convert_rc</option><option value=\"0\"></option>"; select_reasoncode(); 
echo "</select>\n"; 

所有預設paramters鏈接：

echo "<a href=\"file_action.php?id=$id&confirmsubmit=1&uid=$uid\" title=\"Submit\"><img src=\"images/submit.png\" border=\"0\"></a> 

所以基本上我想要的待辦事項是莫名其妙的下拉列表中選擇融入我AHREF鏈接像這樣：

echo "<a href=\"file_action.php?id=$id&confirmsubmit=1&uid=$uid&SELECT=$SELECTVAR\" title=\"Submit\"><img src=\"images/submit.png\" border=\"0\"></a> 

這可能嗎？

<select name="reasoncode" id="reasoncode" onchange="changePath();"> 
<option value=""></option> 
<option value="page1.php?id=<?php echo $id;?>&confirmsubmit=1&uid=<?php echo $uid;?>">Option1</option> 
<option value="page2.php?id=<?php echo $id;?>&confirmsubmit=1&uid=<?php echo $uid;?>">Option2</option> 
<option value="page3.php?id=<?php echo $id;?>&confirmsubmit=1&uid=<?php echo $uid;?>">Option3</option> 
</select> 

<a id="link1" href="" target="_blank">CLICK</a> 

<!--jquery min file--> 
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script> 
<script type="text/javascript"> 

function changePath() 
{ 
    var path= document.getElementById("reasoncode").value; 
    alert(path); 
    $("#link1").attr('href',path); 
} 
</script>
