    <br>

         <form:input path="amount" />





    <br>
    <br>
    <input type="submit" class="btn" value="Proceed to recharge">

现在，当用户单击选择运算符时，它应显示特定运算符具有的计划。我正在使用spring mvc。

类似于paytm ..

Answer 1

OnChange of operator call javascript function as

<form:select path="operator" id="operator" onChange="SelectOperator();">         
       <form:option value="Select operator">Select Operator</form:option>         
       <form:option value='Aircel'>Aircel</form:option>         
        ......
</form:select>

编写javascript函数，打开弹出窗口，调用Spring Controller并将此运算符作为

传递

<Script language="javascript">
function SelectOperator() {
    var opr = document.getElementById("operator").value;
    window.open("NEWPOPUP","/controllerURL?operator="+opr);
}
</script>

从此控制器返回的任何页面都将作为弹出窗口打开。

在jsp中显示一个从同一页面获取值的pop
