Question

我花了一些时间来寻找这个，但似乎无法解决这个问题。

我有一个运输下拉，我想拆分运输类型和选择的数量，并将它们分成两个单独的隐藏字段。（我目前正在使用文本字段以便于测试）

例如 - 如果他们选择第一次下降隔夜交付 - 14.00 OnChange我想将shippingtype的值设置为“Overnight Delivery”，并将我的送货字段值设置为“14.00”

我已经有位置工作（如果用户选择了取件，则会出现一个新的下拉列表，您选择的任何内容也会设置我的shippinglocation字段的值）

这是我到目前为止所拥有的......

<script type="text/javascript">
function SetShipping (objDropDown)
{
    var objHidden = document.getElementById("shipping");
    objHidden.value = objDropDown.value; 
}


function setShippingtype (objDropDown)
{
    var objHidden = document.getElementById("shippingtype");
    objHidden.value = objDropDown.value; 
}


function setShippinglocation (objDropDown)
{
    var objHidden = document.getElementById("shippinglocation");
    objHidden.value = objDropDown.value; 
}

function showEntry(obj,optionValue)
{
 //hide all entry selections onchange
 document.getElementById("pickup").style.display="none";
 if(obj.value=="pickup")
 {
  document.getElementById(optionValue).style.display="inline"; 
 }  
}

Answer 1

我冒昧地将您的方法名称从SetShipping更改为setShipping以保持您的命名约定不变。坦率地说，我不能为重新格式化而烦恼，但是经过测试，玩得很开心。

<head>

<script type="text/javascript">
function setShipping (objDropDown)
{
    var objHidden = document.getElementById("shipping");
    var type = objDropDown.options[objDropDown.selectedIndex].text.substring(objDropDown.options[objDropDown.selectedIndex].text.indexOf('-')+2, objDropDown.options[objDropDown.selectedIndex].text.length);
    objHidden.value = type; 
}


function setShippingtype (objDropDown)
{
    var objHidden = document.getElementById("shippingtype");
    var type = objDropDown.options[objDropDown.selectedIndex].text.substring(0, objDropDown.options[objDropDown.selectedIndex].text.indexOf('-')-1);
    objHidden.value = type; 
}


function setShippinglocation (objDropDown)
{
    var objHidden = document.getElementById("shippinglocation");
    objHidden.value = objDropDown.value;
}

function showEntry(obj,optionValue)
{
    //hide all entry selections onchange
    document.getElementById("pickup").style.display="none";
    if(obj.value=="pickup")
    {
        document.getElementById(optionValue).style.display="inline"; 
    }  
}

Answer 2

请格式化您发布的代码，这是可能的。就像你说赶上onChange事件一样。我会以某种方式序列化下拉元素的值。破折号或下划线等，然后对值执行split（）并将相应的拆分存储在相应的隐藏输入值字段中。

例如，为了简洁起见使用原型：

function changeHandler(evt) {
    var selected = evt.target[evt.target.selectedIndex];
    var values = selected.value.split("-");
    $('hidden1').value = values[0];
    $('hidden2').value = values[1];
}

如果下拉选择javascript然后设置文本框的值
