Javascript 我无法使用 ajax 添加新段落

Question

Hi im having this problem, when i use the code only for the嗨，我遇到了这个问题，当我仅将代码用于

(without the "demo2" ) works fine, and in the browser i can see the text that its on "PruebasGeneral/MBVR000008.txt" and when i change this file/text, works in my HTML without refreshing, but i need to add another （没有“demo2”）工作正常，在浏览器中我可以看到它在“PruebasGeneral/MBVR000008.txt”上的文本，当我改变这个文件/文本时，在我的HTML中工作而不刷新，但我需要添加其他

as you can see, i tried to add in the same function, but doesnt work, with this code in the browser in the two paragraph shows whats inside "PruebasGeneral/MBVR000009.txt" so basically shows demo2 and demo2. 如您所见，我尝试添加相同的功能，但不起作用，浏览器中的这段代码在两段中显示了“PruebasGeneral/MBVR000009.txt”中的内容，因此基本上显示了demo2和demo2。 WHAT SHOULD I DO? 我该怎么办？

 <!DOCTYPE html> <html> <body> <p id="demo"></p> <p id="demo2"></p> <script> function loadDoc(path, callback) { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { callback(this.responseText); } }; xhttp.open("GET", path + "?t=" + Math.random(), true); xhttp.send(); } function data1Loaded(data) { document.getElementById("demo").innerHTML = data ; // do something with data } function data2Loaded(data) { document.getElementById("demo2").innerHTML = data ; // do something with data } function loadDocs() { loadDoc('/PruebasGeneral/MBVR000008.txt', data1Loaded); loadDoc('/PruebasGeneral/MBVR000009.txt', data2Loaded); setTimeout(loadDocs, 1000); } window.onload = loadDocs; </script> </body> </html>

You need to have all of that over again.你需要重温这一切。 You can't just call open() twice:你不能只调用open()两次：

 function loadDoc(path, callback) { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { callback(this.responseText); } }; xhttp.open("GET", path + "?t=" + Math.random(), true); xhttp.send(); } function data1Loaded(data) { // do something with data } function data2Loaded(data) { // do something with data } function loadDocs() { loadDoc('path1', data1Loaded); loadDoc('path2', data2Loaded); setTimeout(loadDocs, 1000); } window.onload = loadDocs;
