从文件读取AJAX

此代码应帮助您从远程文本文件中读取：

var txtFile = new XMLHttpRequest();txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);txtFile.onreadystatechange = function() {  if (txtFile.readyState === 4) {  // Makes sure the document is ready to parse.    if (txtFile.status === 200) {  // Makes sure it's found the file.      allText = txtFile.responseText;       lines = txtFile.responseText.split("n"); // Will separate each line into an array    }  }}txtFile.send(null);
