Question

我有这个javascript，它的工作在asp.net好，但我在php中的同一个例子中尝试这个脚本，但没有工作，哪有错？

我有lable包含值，我尝试获取标签值并将其插入隐藏字段，

这是我的剧本

     <script type="text/javascript">

      function Calculate() {
           var Txt_Percent = document.getElementById('<%= txt_Percent.ClientID %>');
           var Txt_Fix = document.getElementById('<%= txt_Fix.ClientID %>');
           if (document.getElementById('<%= rad_Fix.ClientID %>').checked == true) {
           document.getElementById('txt_Percent').disabled = true;

           var lblReadCost = document.getElementById('<%= lbl_Read_Cost.ClientID %>');

           var lblReadCostValue;
           var Lab_Read_Net = document.getElementById('<%= lbl_Read_Net.ClientID %>');
           var hf_Read_Net = document.getElementById('<%= hf_Read_Net.ClientID %>');


           if (navigator.appName == 'Netscape')
               lblReadCostValue = lblReadCost.textContent;
           else
               lblReadCostValue = lblReadCost.innerText;





           if (navigator.appName == 'Netscape')
               Lab_Read_Net.textContent = (eval(lblReadCostValue) - eval(Txt_Fix.value));
           else
               Lab_Read_Net.innerText = (eval(lblReadCostValue) - eval(Txt_Fix.value));

           hf_Read_Net.value = (eval(lblReadCostValue) - eval(Txt_Fix.value));

           if (document.getElementById('<%= txt_Fix.ClientID %>').value == '') {
               Lab_Read_Net.innerText = (eval(lblReadCostValue));
           }



        }

        if (document.getElementById('<%= rad_Percent.ClientID %>').checked == false) {

           Txt_Percent.value = "";
        }


     }

     </script>

    <script type="text/ecmascript">

    function Calculate1() {


        var Txt_Fix = document.getElementById('<%= txt_Fix.ClientID %>');

        if (document.getElementById('<%= rad_Fix.ClientID %>').checked == false) {

            Txt_Fix.value = "";
        }



    }
   </script>

Answer 1

这在PHP中不起作用：

<%= txt_Percent.ClientID %>

因为你没有这些物品。输入字段只是php中的静态HTML。您必须在Javascript中自己设置您在PHP中设置的ID。

Answer 2

您需要更改php echos <%=xxxx %>

的asp response.write（<?php echo $xxx; ?>）

Answer 3

执行类似

的操作

// ASP
var Txt_Percent = document.getElementById('<%= txt_Percent.ClientID %>');

将对象转换为数组然后使用

// PHP
var Txt_Percent = document.getElementById("<?php echo $txt_Percent['ClientID']; ?>");

将asp Javascript转换为php Javascript
