self.getContactInfoGridSettings = ggNamespace.functions.WorkPage_getContactInfoGridSettings; self.lastButton.addClickHandler(function() { if (currentIndexs > 0) { currentIndexs--; } else { currentIndexs = allData.length

根据你的需求，想要在点击“上一步”和“下一步”按钮时重新调用接口以更新参数。你可以在 self.getContactInfoGridSettings() 中添加对接口的调用，确保每次点击按钮时都能获取到最新的数据。

下面是如何修改你的代码，以确保在按钮点击时都会调用相应的接口：

self.getContactInfoGridSettings = ggNamespace.functions.WorkPage_getContactInfoGridSettings;
self.lastButton.addClickHandler(function() {
    if (currentIndexs > 0) {
        currentIndexs--;
    } else {
        currentIndexs = allData.length - 1;
    }
    updateContactPhonePanel();
});
self.nextButton.addClickHandler(function() {
    if (currentIndexs < allData.length - 1) {
        currentIndexs++;
    } else {
        currentIndexs = 0;
    }
    updateContactPhonePanel();
});
function updateContactPhonePanel() {
    self.contactPhones = new ContactPhonePanel({
        custId: allData[currentIndexs].customerId,
        queue: self.queue,
        complaintPhone: self.complaintPhone,
        complaintPhoneNew: self.complaintPhoneNew,
        complaintUsername: self.complaintUsername,
        complaintRelation: self.complaintRelation,
        auto: self.auto,
        callPhone: (phoneNum, customerId) => self.header.callPhone(phoneNum, customerId)
    });
    // 调用获取联系信息设置的方法
    self.getContactInfoGridSettings();
}
ggNamespace.functions.WorkPage.getContactInfoGridsettings = function() {
    const me = this;
    let settings;
    const columns = [];
    
    settings = {
        columns: columns,
        processing: true,
        serverSide: true,
        ajax: {
            url: '../d/detail/contacts',
            contentType: 'application/json',
            type: 'POST',
            lang: defLanguage,
            complete: function() {
                me.contacts = {
                    contactPersons: {},
                    contactNumbers: {},
                    contactIndexs: {},
                    ptpCode: 'promiseToPay',
                    callbackCode: 'callbackRequest',
                    contactPersonIds: {}
                };
                me.mobileContacts = {
                    contactPersons: {},
                    contactNumbers: {},
                    contactPersonIds: {}
                };
                
                me.phoneNumbers = {};
                me.detailAddresses = {};
                me.phoneNumberIndexes = {};
                me.phoneNumberIndexesForSms = {};
                me.contactPersonAddresses = {};
                const selfPhoneNumberArr = [];
                var result = me.contactPhones.contactInfo.getRecords();
                // 在这里处理返回结果
            }
        }
    };
    return settings;
};
