javascript - 在 cookie 检查后，页面继续加载 JS 上的 XML 请求

问题描述

我是 JS 的新手，所以任何帮助将不胜感激。我在页面加载视频时创建了一个 XML 请求以检查 cookie，然后用我网站中的外部 HTML 文件替换 div 元素“tmx”。但是，在将 XML 请求注入“#tmx”之后，页面会在获取 XML 请求后继续重新加载。我注意到的另一件事是，当我在未选中复选框的情况下按下文档上的接受 tnc 按钮时，整个页面正在完全重新加载。我认为这可能是返回值可能是错误的。

 function setCookie(cname, cvalue, exdays) {
  if(document.getElementById('agree').checked){
 const d = new Date();
 d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
 let expires = "expires="+d.toUTCString();
 document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
 }
}

function getCookie(cname) {
  var name = cname + "=";
 var ca = document.cookie.split(';');
 for(var i=0; i<ca.length; i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') c = c.substring(1);
    if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
 }
 return "";
 }

 function checkCookieOnLoad() {
 if(getCookie("clicklink") === "yes") {
 


   var elem = document.getElementById("tmx");
                elem.parentNode.removeChild(elem);

                // var elem2 = document.getElementById("ooo");
                // elem2.parentNode.removeChild(elem2);


            var video = document.createElement('video');
            video.type = "video/mp4";
            video.src = ".//vid1.mp4";
            video.autoplay = true;
            video.muted = true;
            video.id = "vdd1"
            document.body.appendChild(video);

            
            video.addEventListener("timeupdate", function(){
            // current time is given in seconds

                            if(this.currentTime >= 4.8) {
                                // pause the playback
                                this.pause();
                                this.remove();
                                
                                location.replace("https://www.test.com/index.html");
                                }

            });

   return true;

  
 
   } else {
 
    const xhr = new XMLHttpRequest();
          const contianer = document.getElementById('tmx');
          xhr.onload = function() {
            if (this.status ===200){
              contianer.innerHTML = xhr.responseText;
            }
          }
          xhr.open('get', 'tnc.html');
          xhr.send();
 
 
   }
  }
