jQuery从文本文件中获取随机行

Question

I have a .txt file, with around 754 lines. Each line has a pattern like this:

1st part text#2nd part text#3rd part text or number

The hashtag is the delimiter!

What I'm trying to do is to get() or read() this text file, and retrieve a random line from it, with all the pattern. But it has to be a random line. So I can print it or append html to a div. It should look something like this:

• 1st part from a line
• 2nd part from the same line
• 3rd part from the same line

It has this pattern, because maybe I'll have to retrieve only one part of the pattern.

I don't know if a text file is the right type of file to pull data from.... But its only 80kb. There is any way to do this? Could someone give me a hand? I'm actually a designer, this thing is driving me crazy.

What I got... Trying to count how many lines the txt have, so I can get a random line. It doesn't work. Does the text file must have \\n on the end of each line?

$.get('txt/messages.txt', function(txt) {
    var lines = txt.responseText.split("\n");
    for (var i = 0, len = lines.length; i < len; i++) {
        save(lines[i]);
    }
});

I'm using jQuery 1.11.1, and jQuery mobile 1.4.4

Answer 1

This is example of how to pull out a random line from the txt response:

$.get('txt/messages.txt', function(txt) {
    var lines = txt.responseText.split("\n");
    var randLineNum = Math.floor(Math.random() * lines.length);
    save(lines[randLineNum]); // random line from the text file
});

From there you can split that line based on the delimeter ( # ):

lines[randLineNum].split("#");

Here's a jsfiddle example. Hope this helps!
