PHP組合框依賴問題

當客戶點擊他們想要的車庫時，他們選擇一個樓層，根據車庫選擇顯示不同的樓層。代碼的後半部分做同樣的事情。用戶選擇地板，然後他們選擇一個地點，根據地板選擇顯示不同地點。兩個代碼都能單獨工作，但當我嘗試將它們組合在一起時，Spot box在我選擇樓層時不顯示任何信息。PHP組合框依賴問題

您還沒有在樓層選擇框中添加onChange事件。您需要添加

<select name="floor" id="floor" onChange="floor_onchange()">

然後將工作:-)

這個怎麼樣。不一樣的方式，但仍然工作。而且你也錯過了樓層選擇框中的onChange功能。

Garage: 
<select id="garage" name="garage" onchange="garage_onchange();"> 
<option value="S" selected="selected">-Choose Garage-</option> 
<option value="Fordham">Fordham</option> 
<option value="Kingsbridge">Kingsbridge</option> 
</select> 

<br /> 
Floor: 
<select name="floor" id="floor" onchange="floor_onchange();"> 
</select> 

<br /> 
Spot: 
<select name="spot" id="spot"> 
</select> 



<script type="text/javascript"> 
function garage_onchange(){ 
    var selGarageValue = document.getElementById("garage").value; 
    var selFloor = document.getElementById("floor"); 

    if(selGarageValue=="Fordham"){ 
     var html = '<option value="A1">A1</option>'; 
      html += '<option value="B1">B1</option>'; 
      selFloor.innerHTML = html; 
    } 
    else if(selGarageValue=="Kingsbridge"){ 
     var html = '<option value="A2">A2</option>'; 
      html += '<option value="B2">B2</option>'; 
      selFloor.innerHTML = html; 
    } 
} 
function floor_onchange(){ 
    var selFloorValue = document.getElementById("floor").value; 
    var selSpot = document.getElementById("spot"); 

    if(selFloorValue=="A1" || selFloorValue=="A2"){ 
     var html = '<option value="101">101</option>'; 
      html += '<option value="102">102</option>'; 
      html += '<option value="103">103</option>'; 
      html += '<option value="104">104</option>'; 
      html += '<option value="105">105</option>'; 
      html += '<option value="106">106</option>'; 
      html += '<option value="107">107</option>'; 
      html += '<option value="108">108</option>'; 
      html += '<option value="109">109</option>'; 
      html += '<option value="110">110</option>'; 
      selSpot.innerHTML = html; 
    } 
    else if(selFloorValue=="B1" || selFloorValue=="B2"){ 
     var html = '<option value="201">201</option>'; 
      html += '<option value="202">202</option>'; 
      html += '<option value="203">203</option>'; 
      html += '<option value="204">204</option>'; 
      html += '<option value="205">205</option>'; 
      html += '<option value="206">206</option>'; 
      html += '<option value="207">207</option>'; 
      html += '<option value="208">208</option>'; 
      html += '<option value="209">209</option>'; 
      html += '<option value="210">210</option>'; 
      selSpot.innerHTML = html; 
    } 

}
