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

仅使用 1 个文档函数,如果您使用太多 $(document) 函数,则响应中只会返回最后一个函数。
$(document).ready(function(){ //use one doc ready and do your code in this })
并使用您想要运行的其他函数将在 window.load 函数中加载
