警報消息不會使用jQuery

我創建了下面的代碼的形式工作。有一個問題我無法解決。這個問題是在點擊提交按鈕時，警報消息將無法正常工作。警報消息不會使用jQuery

$(document).ready(function() { 
 
    $("#btn_id").click(function() { 
 
    var valid = validate(); 
 
    var name_order = $("#name").val(); 
 
    var address_order = $("#address").val(); 
 
    var city_order = $("#city").val(); 
 
    var state_order = $("#state").val(); 
 
    var zipcode_order = $("#zipcode_id").val(); 
 
    var phone_order = $("#phone_id").val(); 
 
    var email_order = $("#emailid").val(); 
 
    var randID_order = $("#generateID").val(); 
 
    var ICCID_order = $("#ID").val(); 
 

 
    if (valid) { 
 
     $("form[name='workorder']").submit(); 
 
     alert(" Name :" + name_order + " \n Address : " + address_order + 
 
     " \n City : " + city_order + " \n State: " + state_order + 
 
     " \n Zipcode: " + zipcode_order + " \n Phone: " + phone + 
 
     " \n Email: " + email_order + " \n ID: " + randID_order + 
 
     " \n SIM Card: " + ICCID_order) 
 
    } 
 
    }); 
 

 

 

 
    // Give Alert if field not enter 
 
    function validate() { 
 

 
    if (document.workorder.name.value == "") {

    atpos = email.indexOf("@") 
 
    dotpos = email.lastIndexOf(".")

，而不是$（按鈕）。點擊（）在代碼中使用$（形式）.submit爲您的聽衆
形式不具有柱位置。您可以添加return false來提交匿名函數的底部，現在

你有沒有被定義在您的警報調用一個變量「手機」的參考

$("form#form_id").submit(function() { 
var valid = validate(); 
var name_order = $("#name").val(); 
var address_order = $("#address").val(); 
var city_order = $("#city").val(); 
var state_order = $("#state").val(); 
var zipcode_order = $("#zipcode_id").val(); 
var phone_order = $("#phone_id").val(); 
var email_order = $("#emailid").val(); 
var randID_order = $("#generateID").val(); 
var ICCID_order = $("#ID").val(); 

if (valid) {  
    // you don't need to manually submit it since we attached to the submit listener above instead of click 
    // $("form[name='workorder']").submit(); 
    alert(" Name :" + name_order + " \n Address : " + address_order + 
    " \n City : " + city_order + " \n State: " + state_order + 
    " \n Zipcode: " + zipcode_order + " \n Phone: " + phone_order + // you had a bad reference here 
    " \n Email: " + email_order + " \n ID: " + randID_order + 
    " \n SIM Card: " + ICCID_order) 
} 
// return false until you put in a proper post location 
return false;

}）;

我固定一個例子所有這些都是https://jsfiddle.net/algorithmicMoose/n0t83ees/與評論

所以它的工作原理，但你知道爲什麼我的ID和生成的ID將無法包括??。我看到彈出消息，但它是純 – user6589965

你有html標籤爲。我改變了的jsfiddle來更新generateId和ID的HTML標記與測試值向你展示它是如何工作的。 – algorithmicMoose

當你透過（）的形式，你離開頁面。警報（）永遠不會觸發！嘗試代碼更改爲：

if (valid) 
    { 
    alert(" Name :" + name_order + " \n Address : " + address_order + 
     " \n City : " + city_order + " \n State: " + state_order+ 
     " \n Zipcode: " + zipcode_order + " \n Phone: " + phone + 
     " \n Email: "+ email_order + " \n ID: " + randID_order + 
     " \n SIM Card: " + ICCID_order); 
    $("form[name='workorder']").submit(); 

    }
