Answer 1

标记内有<script>个，不确定它是否有效。我删除了那些，只是尝试下面的代码工作。

 <script type="text/javascript">

function mycalculator() {
        var a = parseInt(document.getElementById("a").innerHTML,10);
        var x = parseInt(document.getElementById("odrasli").value,10);
        var c = parseInt(document.getElementById("c").innerHTML,10);
        var y = parseInt(document.getElementById("deca").value,10);
        var aa = a * x;
        var cc = c * y;
        var p = aa + cc;
        var d = p * 0.2;
        document.getElementById("price").innerHTML = p;
        document.getElementById("depozit").innerHTML = d;

        }
function show() {
           document.getElementById('calcres').style.display = "block";
}

function dugme() {
   mycalculator();
   show();
}

</script>




<div class="calculator" style="position:left;"> <!--calculator test-->
<div id ="a" style='display:none;'>2</div>
<div id ="c" style='display:none;'>2</div>
 <input id="odrasli" type="number" placeholder="Number of Adults">
 <input id="deca" type="number" placeholder="Number of Children's">
 </br>
<button value="Submit" class="submite_btn" title="Submit" type="submit" onClick="dugme()"><span class="">Get Price</span></button>
<!-- <input type="button" class= "submite_btn" value="Get Price" onClick="mycalculator()">
-->
 <div id = "calcres" style="display:none;"">
 </br>
 Grand total</br>
    <div id="price"></div> <div class="dolar">$</div></br>
    Deposite </br>
     <div id="depozit"></div> <div class="dolar">$</div></br>
    </div>
 </div>

Answer 2

您的代码有3个问题我必须告诉您：

您必须在JavaScript中使用//comment，而不是 （How to use Comment）
您的<div id =a style='display:none;'>无效，应该是 <div id ='a' style='display:none;'>
换行符应该是<br>或<br />，而不是</br>（HTML linebreak）

另外，我认为在PHP中输出双引号时可能会遇到一些问题(link)

我试图隐藏并用js显示div并运行其他js
