如何比較單個數字與另一個數組中的不同數字？ Java腳本

Question

我有一個ID（示例：2），我有一個列表，其中包含不同的ID（示例：1、2、3、4、5）。 我希望在列表中用1、2、3、4、5以及2是否相等（兩個ID與2 = 2相同）來檢查ID 2。 但是在我的代碼中，它僅檢查第一行。 因此，因為另一個數組以1而不是2開頭，所以我的代碼找不到連接並且不執行任何操作。 像這樣：

        2 = 1 , false
(here it stops) = 2,  false
(here it stops) = 3,  false
(here it stops) = 4,  false

我想要這個：

        2 = 1 , false
        2 = 2 , true -> execute a code
        2 = 3 , false
        2 = 4 , false

有人可以幫我從這里出去嗎 ？ 這是我的代碼：

for (var i = 0; i < emailArray.length; i++) {

    if (ascalda[i].address_email.indexOf(emailArray[i].email_id) >= 0) {
        emaill.push(emailArray[i].email_title);
    }

數組：

ascalda: 

{"address_id":"1",
"address_street":"Vlietstraat",
"address_postalcode":"4536 DG",
"address_housenr":"1",
"address_city":"Terneuzen",
"address_country":"Nederland",
"address_email":"1",
"address_telnr":"1"};





emailArray:
 [
 {email_id: '2', email_title: 'RocWebmail@roc.nl', email_type: '9'},
 {email_id: '1', email_title: 'ScaldaWebmail@scalda.nl', email_type: '8'}
 ];

我使用鈦作為程序。 提前致謝！！

Answer 1

你嘗試過這個嗎

    for (var j = 0; i < ascalda.length; j++) {
     for (var i = 0; i < emailArray.length; i++) {
        if (ascalda[j].address_email == emailArray[i].email_id) {
            emaill.push(emailArray[i].email_title);
        } 
     }
    }

由於兩個值都使用相同的字符串（“ 1”，“ 2” ..）。
