         <p style="margin: 0in 0in 0.0001pt; text-align: center; line-height: normal; font-size: 11pt; font-family: Calibri, sans-serif;" align="center"><span style="color: black;">#{u_beneficiary_record_id.u_dependant_share_of_benefit${i}}</span></p> 
        </td> 
        <td style="border-top: none; border-left: none; border-bottom: solid windowtext 1.0pt; border-right: solid windowtext 1.0pt; padding: 0in 5.4pt 0in 5.4pt; height: 89.5pt;" valign="top" nowrap="nowrap"> 
         <p style="margin: 0in 0in 0.0001pt; text-align: center; line-height: normal; font-size: 11pt; font-family: Calibri, sans-serif;" align="center"><span style="color: black;">#{u_beneficiary_record_id.u_dependant_contact_number${i}}</span></p> 
        </td> 
       </tr>`; 

    }); 


</script> 

</html>

的我如何嘗試使用i

<span style="color: black;">#{u_beneficiary_record_id.u_dependant_contact_number${i}}</span>

如何解決它的價值小窺？

你的i變量遞增。問題是，當你的HTML被添加到你的rowForTable *字符串時，我等於2，當它改變時，它不會影響你的字符串。

你應該把在一個單獨的函數生成HTML代碼，並通過您的增量作爲參數：

$(document).ready(function() { 

    // the increment variable was renamed to avoid confusion 
    var increment = 2; 

    $('#add-rows').bind('click', function() { 
     // calling the appendRow function and passing the increment as a parameter : 
     appendRow(increment++); 
    }); 

    // the fonction that will generate your HTML code with a variable 'i' passed as parameter : 
    function appendRow(i) { 
     var rowForTableOne = ...; // put your previous code here 
     var rowForTableTwo = ...; // put your previous code here 

     // appending the rows to your document : 
     $('#table1 tbody').append(rowForTableOne); 
     $('#table2 tbody').append(rowForTableTwo); 

    } 



});
