記住選定值我有從我的數據庫中的數據鏈接的下拉菜單...從鏈式下拉

這是它的外觀：

我想記住提交後每個下拉列表中選定的值。所以，我可以改變顏色上的一個簡單的方法，而不是走線槽再次所有的下拉菜單...

我得到它的工作的第一個下拉具有：

<option value="<?php echo $tier['make'];?>"<?php echo (isset($_POST['drop_1']) && $_POST['drop_1'] == $tier['make']) ? ' selected="selected"' : '' ; ?>><?php echo $tier['make'];?></option>

應該與其他的下拉列表中工作太不是嗎？

是否可以顯示下拉列表而不是逐個顯示？

在此先感謝

不要混淆JavaScript和Java。 –

「不是一個人」是什麼意思？ –

我提交選定的值後，我必須從第一個下拉菜單開始...所以我必須再次選擇品牌/型號/年份和顏色，以改變同一輛車的顏色... 對不起，我做了不是很好的閱讀...我的意思是...第二個下拉列表顯示後，你選擇了第一個的東西，等等...... 這就是我所說的「一個一個」，我想顯示所有下拉菜單一次 – user1511766

我認爲你可以這樣做。

<select id="sel1"> 
    <option value="<?php echo $tier['make'];?>"><?php echo $tier['make'];?></option> 
</select> 

<script> 
    var select = document.getElementById('sel1'); 
    select.value = <?php echo $tier['make']); ?> 
    if (select.selectedIndex != 0) { 
     select.style.display = ''; // Show the element 
    } 
</script>

只需添加一個腳本標籤中的每個選擇標籤（或者，如果你想在底部）後，如果您選擇從下拉的任何選項，如果是，則使其可見檢查。

嗨，這不工作...其他下拉框中我仍然沒有提交...所以我甚至不能看到他是否記得輸入值\ – user1511766

@ user1511766如果你能夠得到每個下拉的價值服務器，您應該能夠使用您創建的邏輯來選擇先前選擇的選項，並且在回顯選擇標記後添加JS代碼將確保它們可見。 –

@ user1511766我甚至建議，不要使用條件語句來選擇選項，而是使用javascript方式，而不是在答案中顯示。 –
