AJAX和jQuery拆分

Question

I'm sure this question has been asked before, so I'm sorry if it's a duplicate. I'm pulling in data from a text document using AJAX. How would I separate the paragraphs within the AJAX call so that the paragraphs are split on a paragraph break. I'm showing a change in the html document, but I'm not receiving the results I want. The paragraphs are not splitting up, instead, the paragraph break is simply being removed. FYI, I'm not very experienced with AJAX.

JAVASCRIPT

$(document).ready(function(){
    $.ajax({
        type: "GET",
        dataType: "text",
        url: "text.txt",
        success: function(txt){
            var str = (txt);
            str = (str.split("
"));
            $("#test").append(str);
        }
    });
})

TEXT

This is also the desired output I want, however, This is what I'm getting. I've capitalized where the paragraphs are supposed to split.

Answer 1

var str = text.split('

').map(function(p) { return '<p>' + p + '</p>'; }).join('

')

or, if you need it to work in obsolete browsers,

var str = $.map(text.split('

'), function(p) { return '<p>' + p + '</p>'; }).join('

')
