jquery ajax() berfungsi tidak berfungsi dengan baik atau bahkan diakui
Saya sedang mengusahakan projek menggunakan fungsi ajax jquery. Saya hanya mahu fungsi ajax memaparkan beberapa teks daripada fail pada pelayan apabila butang diklik, tetapi apabila saya mengklik butang itu ia tidak melakukan apa-apa. Saya cuba menambah mesej ralat tetapi itu nampaknya tidak berfungsi sama ada. Saya telah memastikan untuk menggunakan versi jquery yang menyokong fungsi ajax, malah saya telah menyalin dan menampal kod daripada sumber yang saya tahu berfungsi, tetapi tiada apa yang nampaknya berfungsi.
Fail skrip java saya
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();
}
