Question

我有一个手风琴，有一个小组，我只想表明是否符合某些标准。面板ID是“product-options”。

我有几个javascript函数，一个是从下拉列表中验证状态（下拉列表id =“省”），另一个是用复选框验证年龄（复选框id =“age_verification”）。手风琴面板“product-options”通过标题激活，id =“BuyThis”。

我想要的是当状态与列表匹配时仅显示面板“product-options”。

这是我的脚本：

<script>
// Validates State is in list of allowed for wine shipping...  
function validateState() {
      // Confirms province is allowed for wine shipping     
          var states = ["Alaska", "Arizona", "California", "Colorado", ""];
                 if ($.inArray($("#province").val(), states) <0) {
                 alert("Shipping gifts containing alcohol to this state is prohibited by law. Please choose another item.");
                 return false;       
        }
alert("Item Available! Please choose your options.");
return true;
}
    // Validates age verification is checked...   
    function validateAge() {    
        if (!$('#age_verification').is(':checked')) {
            alert("Please verify you are 21 years of age or older.");
            return false;       
        }    
return true;
}
</script>

对应的HTML：

<h3 id="BuyThis" onclick="return validateState();"><button class="Button buyThisBtn"><i class="icon-shopping-cart"></i>&nbsp;&nbsp;Buy This!</button></h3>              
<div class="ProductContainer" id="product-options"> 
    <form>
    [BODY OF ACCORDION PANEL WITH A BUNCH OF IRRELEVANT CODE......]     

             <button id="addtocart" type="submit" class="Button" onclick="validateAge(); return validateState();"><i class="icon-shopping-cart"></i> ADD TO CART</button>                   
    </form>
</div>

我尝试将以下内容无效：

$(function () {
    $("#buyThis").change(function () {
    if ($.inArray($("#province").val(), states) <0) {                
         alert("Shipping gifts containing alcohol to this state is prohibited by law. Please choose another item.");
         $("product-options").hide();               
    }                
$("product-options").show();             
}

Answer 1

试试这样：

<h3 id="BuyThis" ><button class="Button buyThisBtn"><i class="icon-shopping-cart"></i>&nbsp;&nbsp;Buy This!</button></h3>              
<div class="ProductContainer" id="product-options"> 
    <form>
    [BODY OF ACCORDION PANEL WITH A BUNCH OF IRRELEVANT CODE......]     

             <button id="addtocart" type="submit" class="Button" onclick="validateAge(); return validateState();"><i class="icon-shopping-cart"></i> ADD TO CART</button>                   
    </form>
</div>


$(function () {
    $("#buyThis").click(function () {

if(validateState()){

       if ($.inArray($("#province").val(), states) <0) {                
         alert("Shipping gifts containing alcohol to this state is prohibited by law.         Please choose another item.");
         $("product-options").hide();               
       }                
    $("product-options").show();
  }             
}

修改2

请参阅此fiddle并对您的代码进行一些更改：

请注意，您错误地使用$ .inArray方法。在click事件中以及在validateState函数中我认为。

我还对html标记进行了一些更改

请参阅此fiddle，并附上一个工作示例：我希望这可以帮助你。

<强> HTML

<select id="province">
    <option value="Alabama">Alabama</option>
    <option value="Alaska">Alaska</option>
    <option value="Arizona">Arizona</option>
    <option value="Arkansas">Arkansas</option>
    <option value="California">Colorado</option>
</select>
         <button id="test" >Teste</button>  
<h3 id="BuyThis" style="background:red;" >

    <button id="buyThisButton" class="Button buyThisBtn"><i class="icon-shopping-cart"></i>&nbsp;&nbsp;Buy This!</button>
</h3>              
<div class="ProductContainer" id="product-options"> 
    <form>
    [BODY OF ACCORDION PANEL WITH A BUNCH OF IRRELEVANT CODE......]    
        <button id="addtocart" type="submit" class="Button" onclick="validateAge(); return validateState();"><i class="icon-shopping-cart"></i> ADD TO CART</button>                   
    </form>
</div>

的javascript

$( document ).ready(function() {
  // Handler for .ready() called.

    $("#BuyThis").click(function() {
    //alert("test");

     if(validateState()){
         // if state is valid do this

     }else{
     // do that

     }
  });


}); // end of dom ready



// Validates State is in list of allowed for wine shipping...  
function validateState() {
      // Confirms province is allowed for wine shipping     
          var states = ["Alaska", "Arizona"];
                 if ($.inArray($("#province").val(), states) >= 0) {                     
                 alert("Oh no! Shipping items containing alcohol to this state is prohibited by law. Please choose another item.");
                 //$("#BuyThis").unbind("click");
                 $("#product-options").slideUp(); 
                 return false;       
        }
    alert("Item Available! Please choose your options.");
    $("#product-options").slideDown();  
    return true;
}


    // Validates age verification is checked...   
    function validateAge() {    
        if (!$('#age_verification').is(':checked')) {
            alert("Please verify you are 21 years of age or older.");
            return false;       
        }    
return true;
}
