驗證碼彈出窗口

Question

我要添加驗證碼在彈出窗口。

我在列表中有一些類別**（按需服務）**。如果任何人點擊任何服務，則根據服務ID打開一個彈出窗口。它的工作正常。

但我也有驗證碼在JavaScript中。但它不工作。如果任何人點擊任何服務，那麼應該打開一個彈出窗口，根據服務ID和驗證碼應該存在。我試過了，但沒有發生。

不能在表單中使用同一ID多次。 Id必須是唯一的。而不是它使用類。你可以改變y代碼如下。你也沒有my_modal2在你的代碼，所以先定義它

<script type="text/javascript"> 

    //Created/Generates the captcha function  
function DrawCaptcha(modal_id) 
{ 
    var a = Math.ceil(Math.random() * 10)+ ''; 
    var b = Math.ceil(Math.random() * 10)+ '';  
    var c = Math.ceil(Math.random() * 10)+ ''; 
    var d = Math.ceil(Math.random() * 10)+ ''; 
    var e = Math.ceil(Math.random() * 10)+ ''; 
    var f = Math.ceil(Math.random() * 10)+ ''; 
    var g = Math.ceil(Math.random() * 10)+ ''; 
    var code = a + ' ' + b + ' ' + ' ' + c + ' ' + d + ' ' + e + ' '+ f + ' ' + g; 
    //document.getElementById("txtCaptcha").value = code 
    txt_captcha="#"+modal_id+" .txtCaptcha"; 
    console.log(txt_captcha); 
    $(txt_captcha).val(code);
