如何使用Javascript从值读取换行符并用<br />标签替换所有换行符？

例:

从PHP传递的变量如下:

  "This is man.

     Man like dog.
     Man like to drink.

     Man is the king."

在Javascript转换后,我希望我的结果看起来像这样:

  "This is man<br /><br />Man like dog.<br />Man like to drink.<br /><br />Man is the king."

我有一个链接,在broswer 中打开json数据但不幸的是我不知道如何阅读它.有没有办法使用javascript逗号分隔(csv)格式转换此数据并将其保存在javascript变量中.我刚刚开始学习并且对json完全没有任何线索,如果有人可以为它编写脚本会很棒.

数据似乎如下:

{
  "count": 2,
  "items": [{
    "title": "Apple iPhone 4S Sale Cancelled in Beijing Amid Chaos (Design You Trust)",
    "description": "Advertise here with BSA Apple cancelled its scheduled sale of iPhone 4S in one of its stores in China\u2019s capital Beijing on January 13. Crowds outside the store in the Sanlitun district were waiting on queues overnight. There were incidents of scuffle between shoppers and the store\u2019s security …

如何在 Java 字符串中找到最后一个可见字符？我想从 Java 字符串中删除所有换行符和其他不可见字符

我发现了一个有趣的问题,来自JQuery的AJAX请求的回显值,我没有回答:

我data == "LOCKED"永远不会回归真(第13行)!

JQuery - >按下单击时调用AJAX:

$.ajax({
        url: "ajax/login_ajax_call.php",
        method: "POST",
        data: { user: usr, password: pwd }
    }).done(function(data){
            if(data == true || data == "true"){          // -> this works with data beeing true (bool) or "true" (string)
                $("#form_submit").submit();
            }
            else{
                console.log(jQuery.type(data));          // -> (string)
                console.log(data);                       // -> "LOCKED" 
                console.log(jQuery.type("LOCKED"));      // -> (string)
                if(data == "LOCKED"){                    // also tried "===" but it never returns true
                    [...]            
                }
                else{
                    [...]
                }
            }
    }); 
});             

PHP(1) - >获取类返回的值(PHP(2)): …

我有一个像下面这样的文本文件

id      nm              lat         lon         countryCode
819827  Razvilka        55.591667   37.740833   RU
524901  Moscow          55.752220   37.615555   RU
1271881 Firozpur        27.799999   76.949997   IN

我需要像下面的格式一样转换为json

[{"id":819827,"nm":"Razvilka","lat":55.591667,"lon":37.740833,"countryCode":"RU"},
{"id":524901,"nm":"Moscow","lat":55.752220,"lon":37.615555,"countryCode":"RU"},
{"id":1271881,"nm":"Firozpur","lat":27.799999,"lon":76.949997,"countryCode":"IN"}]

对于 javascript 应用程序。

myapp.controller('TCtrl', ['$scope', '$http', function($scope, $http) {
  $http.get('list.txt').success(function(data) {
    $scope.todos = JSON.parse(data);
    //console.log(data)
  });
}]);
