如何在ajax请求完成后1秒递归调用函数?(How to recursively call a function 1 second after an ajax request is done?)

我有一个案例,我不想每秒调用一个方法。 相反,我想在完成ajax请求后1秒钟调用一个函数,而不管结果如何。

我试图使用$.delay()函数,但它给了我一个错误

TypeError: $.delay is not a function

这是我的代码

$(function(){
    function checkMessages(){

        $.ajax({
            type: 'GET',
            url: icwsHandlerUrl,        
            data: {method: 'getMessages', jSON: true},
            dataType: 'json',
            cache: false,
            timeout: 5000,
            success: function(data) {
                console.log(data); // for testing only but this should call a handler for the data  
            },
            complete: function(){
                $.delay(1000, function(){
                    checkMessages();
                });
            }
        });

    }

    $(window).load(function(){
        checkMessages();
    });
});

注意:我使用的是jQuery 2.1.0版


I have a case where I do not want to call a method every second. Rather, I want to call a function 1 second after the ajax request is completed regardless of the result.

I tried to use the $.delay() function but it gives me an error

TypeError: $.delay is not a function

Here is my code

$(function(){
    function checkMessages(){

        $.ajax({
            type: 'GET',
            url: icwsHandlerUrl,        
            data: {method: 'getMessages', jSON: true},
            dataType: 'json',
            cache: false,
            timeout: 5000,
            success: function(data) {
                console.log(data); // for testing only but this should call a handler for the data  
            },
            complete: function(){
                $.delay(1000, function(){
                    checkMessages();
                });
            }
        });

    }

    $(window).load(function(){
        checkMessages();
    });
});

Note: I am using jQuery version 2.1.0

最满意答案

$.delay用于延迟存储在jQuery事件队列中的事件。 为此,您应该使用JavaScript自己的setTimeout方法:

setTimeout(checkMessages, 1000);

$.delay is used to delay events which are stored in jQuery's event queue. For this you should use JavaScript's own setTimeout method instead:

setTimeout(checkMessages, 1000);
