如何将json字符串解析为整数？ （ajax）

Question

我对这些代码有疑问。

<script>
$(function() {
    $('#submitRegister').click(function (e) {
        console.log('jalan fungsi submit');
        e.preventDefault();
        var paramObj = {};
        $.each($('#registerForm').serializeArray(), function (_, kv) {
            if (paramObj.hasOwnProperty(kv.name)) {
                paramObj[kv.name] = $.makeArray(paramObj[kv.name]);
                paramObj[kv.name].push(kv.value);
            }
            else {
                paramObj[kv.name] = kv.value;
            }
        });
        console.log(paramObj);

        var dataMitra = paramObj;
        var urlAjax = "my url";

        $.ajax({
            type: "POST",
            url: urlAjax,
            contentType: "application/json; charset=utf-8",
            data: dataMitra,
            crossDomain: true,
            success: function (data) { alert("ajax worked"); },
            error: function (data) { console.log(data); },
            dataType: "json",
            beforeSend: function (xhr) {
                xhr.setRequestHeader("content-type", "application/json");
                xhr.setRequestHeader("accept", "application/json");
            },
            headers: {
                'Access-Control-Allow-Origin': '*'
            }
        });
    });
});

使用ajax发布到我的API，使用整数需要几个字段。在下面看起来是json

================================================ =

ada_lahan: "1" *
alamat_juragan: "jalan intan v no. 192"
alamat_lahan: ""
code: "10640" *
country_id: "100" *

注意：*表示应为整数值

我如何将字符串值解析为整数？仅适用于几个领域。 谢谢
