如何从输入创建数组？

Question

I created multiplied input fields:

<div class="form-text-field first-name field-group">
    <input data-index="1" type="text" id="firstName1" class="signup-input firstName" name="first[1]" placeholder="">
</div>
<div class="form-text-field email field-group">
    <input type="text" data-index="1" id="inputMail1" class="signup-input text-value ignore" name="email[1]"  placeholder="${message(code:"signup.redesign.placeholder.eg.email")}"/>
    <span class="common-sprite disNone sign-up-cross first clone"></span>
</div>

I have a code in the JS file which clone every input.

I have to create arrays from the values of the inputs (one for the email, and one for the first name).

Here is the function:

var arrEmail = []
var arrName = []
function add() {
    var obj = {};
    var partner = {}
    $('.email input[type="text"]').each(function() {
        obj[this.data-index] = this.value;
    });
    arrEmail.push(obj)
    $('.first-name input[type="text"]').each(function() {
        partner[this.data-index] = this.value;
    });
    arrName.push(partner)
    console.log(arrEmail[0])
}

I didn't succeed to get the arrays in this code. How do I fix it?

Answer 1

You have some mistakes.

1. Wrong syntax in line $('.email input[type="text"]').each(function({ . You forgot to close bracket.
2. I don't understand why you tried get value this strange manner. You included jQuery. Use it!

I fix your code.

var arrEmail = [];
var arrName = [];

function add() {
    var obj = {};
    var partner = {};
    $('.email input[type="text"]').each(function(item) {
        obj[$(this).data('index')] = $(this).val();
    });
    arrEmail.push(obj);

    $('.first-name input[type="text"]').each(function() {
        obj[$(this).data('index')] = $(this).val();
    });
    arrName.push(obj);

    console.log(arrEmail);
    console.log(arrName);
}

$('#test').on('click', add);

Haven't shown all conditions. Fixed it.

Answer 2

使用$(this).data('index')代替this.data-index

Answer 3

You can handle this with a single array:

var myUsers= [];//this might be object that you store the user information

$('.first-name input[type="text"]').each(function(item) {
    //first create the user information
    var myUser = new Object();
    myUser.Username = $(this).val();
    myUser.Email= $(this).next().val();

    //then add the user information to the myUsers array
     myUsers.push(myUser );
});
