我目前正在开发一个使用 jquery ajax 函数的项目。我只是希望 ajax 函数在单击某个按钮时显示服务器上文件中的一些文本，但当我单击该按钮时它什么也不做。我尝试添加错误消息，但这似乎也不起作用。我已经确保使用支持 ajax 功能的 jquery 版本，我什至从我知道有效的来源复制并粘贴了代码，但似乎没有任何效果。

我的java脚本文件

window.onload=loadDoc(); 

$(document).ready(function(){   // the function that should be getting called 

    $("#accountInfo").click(function(){ 

        $.ajax({url: "accountPerks.txt",  
            error: function(xhr, status, error) {
                var err = eval("(" + xhr.responseText + ")");
                alert(err.Message); 
            },
        success: function(result){ 

            $("#perksDiv").text(result);

        }});

    });

});  

//everything below here are functions for separate pages  

$(document).ready(function(){ 

    $("#member1Info").click(function(){ 

        $("#BandMember1").css("visibility", "visible");

    });

}); 
$(document).ready(function(){ 

    $("#member2Info").click(function(){ 

        $("#BandMember2").css("visibility", "visible");

    });

}); 

$(document).ready(function(){ 

    $("#member3Info").click(function(){ 

        $("#BandMember3").css("visibility", "visible");

    });

});



function newAlbum(){  

    
    var node = document.createElement("li"); 
    var textNode = document.createTextNode("aaaaallllpxas(2023)"); 
    node.appendChild(textNode); 
    document.getElementById("albumList").appendChild(node); 
    
    $("#sneakPeak").css("visibility", "hidden");
}


var getAlbum = document.getElementById("sneakPeak");  
getAlbum.onclick=function(){ 

    newAlbum();
}
  
    
function loadDoc() { 
    var xhttp = new XMLHttpRequest(); 
   xhttp.onreadystatechange = function(){ 
       if(xhttp.readyState == 4 && xhttp.status == 200){ 
           document.getElementById("ExtraText").innerHTML = xhttp.responseText;
       }
   }; 
   xhttp.open("GET", "TourInfo.txt", true); 
   xhttp.send();
}

我希望文本文件出现在的页面
