Question

由于AJAX函数在main函数之后执行， pos 总是返回值0并且无法获取实际值。

如何在主函数

之前执行ajax函数

    var pos = 0;
jQuery(function ($) {
  jQuery.ajax({
        url: wpws_ajaxurl,
        type: "POST",
             dataType: 'json',
               cache: false,
        data: {
            action: 'getData',
               key: Id
        },
        success: function(pos){
                        pos = JSON.parse(pos)
        },
        error: function (jqXHR, text, status) {
        alert(JSON.stringify(jqXHR) + " Error");
    }
    });
});
/*main function starts here*/
jQuery(function ($) {

    if (pos)
    var timer = setInterval(function () {
        if (typeof demo !== "undefined") {
        demo.setCurrentTime(pos);
        clearTimeout(timer);
        }
    }, 1000);
});

拜托，有人可以帮我吗？

Answer 1

两者看起来都很重要。使用名称保持您的AJAX特定功能。例如：

function MyAJAX() {
   //your AJAX Function
}

在main函数内调用MyAJAX()。它将提供所需的POS值。

/ 主要功能从这里开始 /

jQuery(function ($) {
    MyAJAX()    
    if (pos)
    var timer = setInterval(function () {
        if (typeof demo !== "undefined") {
        demo.setCurrentTime(pos);
        clearTimeout(timer);
        }
    }, 1000);
});

您可以使用jQuery Promises来完成此任务。

    SwsLogoCorner.alpha=0

    no.removeEventListener(MouseEvent.CLICK, yesnofadeout)
}

现在你要访问pos的值。

import flash.events.Event;
import flash.system.fscommand;
import flash.events.MouseEvent;
setupplanet();
Foreground.alpha=0
function setupplanet():void
{
    Foreground.addEventListener(Event.ENTER_FRAME, PlanetLoop)
}
function PlanetLoop(e:Event=null):void
{
    if(GameMode==0){
        Foreground.alpha=0
    } else {
        Foreground.alpha=1
    }
            Foreground.gotoAndStop(1)
}

Answer 3

我认为你应该在你的main函数中进行ajax调用，并在“success”ajax函数中检查“pos”值。

Answer 4

我认为你应该这样做你的ajax请求：

$.ajax({
    url: ... ,
    type: ... ,
    data: ... 
}).done(function() {
    // change the value of 'pos' if necessary
    // call your main function
});

因为done仅在ajax请求返回

时执行

Answer 5

在ajax调用中添加async:false解决了我的问题。非常感谢Nishant Solanki：）

ajax函数的值稍后返回
