Javascript AJAX和jQuery的拆分

我肯定这个问题以前有人问过，所以如果是重复的话，我很抱歉。我正在使用AJAX从文本文档中提取数据。我如何在AJAX调用中分离段落，以便在段落中断时分割段落。我正在显示html文档中的更改，但没有收到我想要的结果。段落没有分开，相反，段落分隔符只是被删除。仅供参考，我对AJAX不是很有经验

JAVASCRIPT

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

greater necessity. Although it may not happen to you, and we all hope it never
does, the truth is, break-ins happen. The best way to deal with this dangerous
situation is to install a security system that will help prevent thieves from

这也是我想要的输出，然而，这是我得到的。我已经把段落应该分开的地方大写了

谢谢您的帮助。

var str=text.split（'\n\n'）.map（函数（p）{return''+p+'
'；}）。join（'\n\n'））
var str = text.split('\n\n').map(function(p) { return '<p>' + p + '</p>'; }).join('\n\n')

或者，如果您需要它在过时的浏览器中工作

var str = $.map(text.split('\n\n'), function(p) { return '<p>' + p + '</p>'; }).join('\n\n')

var str=$.map（text.split（'\n\n'），函数（p）{return''+p+'
'；}）。join（'\n\n'））

只需将拆分的代码替换为replace，这样换行符就会被HTML等价物替换
，如下所示：

function(txt){
    stri = txt.replace(/\n/g, "<br/>");
    $("#test").append(stri);
}

函数（txt）{
stri=txt.replace（/\n/g，“
”）；
$（“#测试”）。追加（stri）；
}

替换使用正则表达式/\n/检测换行符\n

---

注意：g后缀表示全局，例如处理所有出现的\n

如何将它们分开？你认为stri是什么

console.log（）

it！哎呀，stri应该是str，我的错。我修好了。
