中止AJAX請求ZeptoJS

Question

我想知道是否有辦法.abort()在jQuery中使用.abort()一樣終止ZeptoJS中的AJAX調用。

我已經嘗試過了，但是我一直收到這個錯誤：

Uncaught TypeError: Object #<t> has no method 'abort' 

這就是AJAX調用的樣子：

SITE.Address.pendingZipLookup = $.ajax({
    url: '/us/en-us/services/globalization/getcitysuggestions',
    data: {"ZipCode" : newZipCode},
    type: 'POST',
    success: function (data) {
        if(SITE.Address.suppressZipLookup) return;
        if(data.length === 0) {
            SITE.Navigation.showModal( SITE.TextTranslations.address.noAddressText , SITE.TextTranslations.address.noAddressHeading );
        } else if(data.length == 1) {
            SITE.Address.fillAddressElm($addressFormItem, data[0]);
        } else {
            SITE.Navigation.showModal(  Mustache.to_html( $tmplSelectCity.html(), {Cities:  data} ) , SITE.TextTranslations.address.selectCity );
            $('.modal').find('.modal-header .buttonClose').one('click', clearForm).end();
        }
    },
    error: function() {}
});

我在變量上調用.abort() ：

if ( SITE.Address.pendingZipLookup !== null && SITE.Address.pendingZipLookup.readyState !== 4 ) {
    console.log(SITE.Address.pendingZipLookup.readyState);
    SITE.Address.pendingZipLookup.abort();
}

.readyState都.readyState求值，它只會在控制台中返回undefined 。

編輯：這是登錄控制台時SITE.Address.pendingZipLookup外觀：

如果看起來很奇怪，那是因為我復制了在控制台中獲得的對象，如果有更好的方法來打印結果，則應該讓我知道:)

Answer 1

• 首先，您需要獲取“請求”實例。 如果使用$.ajax ，則var request = $.ajax(options) 。
• 然后，您可以像這樣編寫： request.abort();

如果您無法獲得請求實例，我認為沒有任何方法可以中止請求。

您可以粘貼代碼。
