javascript setTimeout 在 jquery 中调用 ajax

setTimeout an ajax call in jquery

提问by PinoyStackOverflower

Is there a way to use setTimeout in this ajax call. This is my code:

有没有办法在这个ajax调用中使用setTimeout。这是我的代码：

jQuery.ajax({
    type    : "POST",
    url     : dir+"all/money/myFile.php",
    data    : "page="+data.replace(/\&/g, '^'),
    success : function(msg) {
    var info = jQuery('.product_overview #allinfo').html();
    var url = '<a href="http://www.mySite.com/openMe/letmeview.php?preview='+msg+'.html" target="_blank" class="check_link_preview" rel="'+msg+'.html">Check Preview</a>';          jQuery('.option_additional').next().find('textarea:first').text(info+url);
                },
    complete: function() {
    jQuery('.add-to-cart button.btn-cart').delay(500).trigger('click');
}
});

I want to do something before this ajax will be triggered that is why I'll use setTimeout or something that would delay this action.

我想在这个 ajax 被触发之前做一些事情，这就是为什么我会使用 setTimeout 或会延迟这个动作的东西。

How would I do that?

我该怎么做？

Thanks in advance :)

提前致谢 ：）

You can use beforeSend, Example

您可以使用beforeSend， 示例

$(function() {

    function callBeforeAjax() {
        alert('and now do ajax');
    }

    $.ajax({
        beforeSend: callBeforeAjax,
        type: "POST",
        url: "/",
        data: "",
        success: function(msg) {},
        complete: function(msg) {
            alert(msg);
        }
    });
});

Haven't used jquery with setTimeout before but try

之前没有使用过带有 setTimeout 的 jquery，但请尝试

var t = window.setTimeout(function, delay);

replace function in the above code with your jquery function.

用你的 jquery 函数替换上面代码中的函数。

In a complete function:

在一个完整的函数中：

complete: function () {
  setTimeout(function () {
     // your action here
  }, 500);
}

@Tols is right, it works. Try something like this: setTimeout(function(){jQuery('.add-to-cart button.btn-cart').trigger('click');}, 500);

@Tols 是对的，它有效。尝试这样的事情：setTimeout(function(){jQuery('.add-to-cart button.btn-cart').trigger('click');}, 500);
