在viewcart.tpl中自定义滑块形式的购物车

Question

我希望你们中的一些人熟悉WHMCS和聪明的模板语言，这样你们就可以帮助我。我遇到的问题是滑块订单表单模板的viewcart.tpl页面。我想在您第一次进入此页面时隐藏此页面上的购物车和完整的订单按钮。我想添加一个循环回到同一页面的继续按钮。当页面循环回到自身时，您可以看到购物车和完成订单按钮，并且将隐藏继续按钮。我希望继续按钮仅在填写订单表单字段时才起作用。

以下是该页面的代码：

<link rel="stylesheet" type="text/css" href="templates/orderforms/{$carttpl}/style.css" />

<script language="javascript">var statesTab=10;</script>

<script type="text/javascript" src="templates/orderforms/{$carttpl}/js/main.js"></script>

<script type="text/javascript" src="includes/jscript/statesdropdown.js"></script>

<script type="text/javascript" src="includes/jscript/pwstrength.js"></script>

<script type="text/javascript" src="includes/jscript/creditcard.js"></script>



{literal}<script language="javascript">

function removeItem(type,num) {

    var response = confirm("{/literal}{$LANG.cartremoveitemconfirm}{literal}");

    if (response) {

        window.location = 'cart.php?a=remove&r='+type+'&i='+num;

    }

}

function emptyCart(type,num) {

    var response = confirm("{/literal}{$LANG.cartemptyconfirm}{literal}");

    if (response) {

        window.location = 'cart.php?a=empty';

    }

}

</script>{/literal}

非常感谢帮助。如果有其他方式或更简单的方法来隐藏购物车和完成订单按钮，直到订单填写完毕，您能告诉我吗？我已经想过添加另一个滑块订单表单模板页面并将购物车移动到该页面但不幸的是我不认为你可以做到WHMCS设置方式的原因。

Answer 1

你应该做的是使用JavaScript来实现这一目标。您应该使用onchange或oninput方法跟踪更改并显示所需内容。当然应该启用浏览器中的JavaScript。

示例工作代码：

<html>

<head>
<meta charset="utf-8" />
</head>

<style type="Text/css">
#mycart, #continue {
    display: none;
}

</style>
<body>

<div id="mycart">My cart</div>

<form method="post">

<input type="text" name="name" id="name" oninput = "check()" onchange = "check()" />

<select name="options" id="options" onchange = "check()">

<option value="0">Select option</option>
<option value="1">option1</option>
<option value="2">option2</option>
</select>

</form>

<div id="continue">Continue</div>

<script>
    function check() {
       var text = document.getElementById("name").value.trim();
       var option = document.getElementById("options");
       option = option.options[option.selectedIndex].value 

       if (text != '' && option != 0 ) {
           document.getElementById("mycart").style.display = 'block';
           document.getElementById("continue").style.display = 'block';

       }
       else {
           document.getElementById("mycart").style.display = 'none';
           document.getElementById("continue").style.display = 'none';           
       }

    }

</script>
</body>
</html>

当然，您需要根据需要调整代码。
