将文本文件的内容转换为javascript变量

Question

我正在使用桌面通知。我使用这个代码来显示它，和它的做工精细：

// If the user is okay, let's create a notification 
if (permission === "granted") { 
    var options = { 
    body: "This is the body of the notification", 
    icon: "icon.jpg", 
    dir : "ltr" 
    }; 
    var notification = new Notification("Hi there",options); 
} 

但我怎么能取从文本文件数据到options.body？

Answer 1

适应从this answer代码，最终的结果应该是这样的：

// If the user is okay, let's create a notification 
if (permission === "granted") { 
    var options = { 
    icon: "icon.jpg", 
    dir : "ltr" 
    }; 
    var XHR = new XMLHttpRequest(); 
    XHR.open("GET", "notificion.txt", true); 
    XHR.send(); 
    XHR.onload = function(){ 
    options.body = XHR.responseText; 
    var notification = new Notification("Hi there",options); 
    }; 
} 

Answer 2

例使用JQuery $.get()

if (permission === "granted") { 
    $.get("notificion.text", function(data) { 
    var notification = new Notification("Hi there", { 
     icon: "icon.jpg", 
     dir: "ltr", 
     body: data 
    }); 
    }); 
}
