我如何在我的jsfiddle中使用那个json？

Answer 1

JSFiddle不允许您上传JSON文件来发出AJAX请求。您将需要一些其他方式来托管文件，以便您可以调用它们。最好的办法是将它们上传到外部服务器上，最好是你的服务器。

JSON-P救援！

由于文件将在jsfiddle.net域之外托管，因此您需要制作CORS request或更简单的解决方案JSON-P request，这样您就可以制作跨域AJAX请求检索JSON数据。

如果我无法托管文件怎么办？

在您自己的网络上访问JSON文件应该不是问题。由于这是一个JSFiddle问题，因此您只能执行上面建议的操作。有人建议使用JSFiddle模拟AJAX请求，但这仍然需要您将JSON直接粘贴到编辑器中。如果您无法在外部托管JSON，那么您可以做的最少就是将其包装在脚本末尾的函数中。这将使它远离视线，因此您无需滚动它。

这是一个JSFiddle，使用您提供的JSON演示他们的模拟AJAX功能：http://jsfiddle.net/MrPolywhirl/QsHw4/6352/

注意：如果您使用的是HTTPS连接，则无法在JSFiddle中通过HTTP调用文件。如果您无法使用HTTPS调用请求，则需要找到另一种方法来访问该文件。

使用模板语言的解决方案

以下是一个示例，一个在Angular中，一个在jQuery中，它使用JSON-P生成相同的ouptup。

使用Angular的解决方案

使用外部托管的JSON文件：

http://beta.json-generator.com/api/json/get/CK4M2Hk?indent=2&callback=JSON_CALLBACK

您可以在Angular JS中发出JSONP请求，如下所示：

var jsonDataUrl = 'http://beta.json-generator.com/api/json/get/CK4M2Hk?indent=2&callback=JSON_CALLBACK';

var countryApp = angular.module('countryApp', []);

countryApp.controller('CountryCtrl', function($scope, $http) {
  $http.jsonp(jsonDataUrl)
    .success(function(data) {
      console.log(data);
      $scope.countries = data;
    });
});

table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="countryApp">
  <div ng-controller="CountryCtrl">
    <table>
      <thead>
        <tr>
          <th>Country</th>
          <th>Population</th>
        </tr>
      </thead>
      <tbody>
        <tr ng-repeat="country in countries">
          <td>{{country.name}}</td>
          <td>{{country.population}}</td>
        </tr>
      </tbody>
    </table>
  </div>
</div>

使用jQuery

的解决方案

如果你不熟悉Angular，这里有一个jQuery实现。

var jsonDataUrl = 'http://beta.json-generator.com/api/json/get/CK4M2Hk?indent=2&callback=JSON_CALLBACK';

$(function() {
  $.ajax({
    type: 'GET',
    url: jsonDataUrl,
    async: false,
    jsonpCallback: 'JSON_CALLBACK',
    contentType: "application/json",
    dataType: 'jsonp',
    success: function(data) {
      addRows($('#countryTable'), data, ['name','population']);
    },
    error: function(e) {
      console.log(e.message);
    }
  });
});

function addRows(table, data, fields) {
  var tbody = table.find('tbody');
  $.each(data, function(i, item) {
    tbody.append(addRow(item, fields));
  });
  return tbody;
}

function addRow(item, fields) {
  var row = $('<tr>');
  $.each(fields, function(i, field) {
    row.append($('<td>').html(item[field]));
  });
  return row;
}

table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<table id="countryTable">
  <thead>
    <tr>
      <th>Country</th>
      <th>Population</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

使用HandlebarsJS的解决方案

与jQuery示例类似，只是我们使用模板而不是插入DOM元素。

var jsonDataUrl = 'http://beta.json-generator.com/api/json/get/CK4M2Hk';

$(function() {
  var theTemplateScript = $("#country-template").html();   // Grab the template script
  var theTemplate = Handlebars.compile(theTemplateScript); // Compile the template
  
  $.ajax({
    type: 'GET',
    url: jsonDataUrl,
    async: false,
    jsonpCallback: 'JSON_CALLBACK',
    contentType: "application/json",
    dataType: 'jsonp',
    success: function(data) {
      var theCompiledHtml = theTemplate(data);  // Pass our data to the template

      $('body').append(theCompiledHtml); // Add the compiled html to the page
    },
    error: function(e) {
      console.log(e.message);
    }
  });
});

table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.5/handlebars.min.js"></script>

<script id="country-template" type="text/x-handlebars-template">
    <table>
      <thead>
        <tr>
          <th>Country</th>
          <th>Population</th>
        </tr>
      </thead>
      <tbody>
        {{#each .}}
        <tr>
          <td>{{name}}</td>
          <td>{{population}}</td>
        </tr>
        {{/each}}
      </tbody>
    </table>
</script>

使用UnderscoreJS的解决方案

HandlebarsJS示例的替代模板。

var jsonDataUrl = 'http://beta.json-generator.com/api/json/get/CK4M2Hk';
var countries = [];

$(function() {
  var tableTemplate = _.template($("#table-data").html());
  
  $.ajax({
    type: 'GET',
    url: jsonDataUrl,
    async: false,
    jsonpCallback: 'JSON_CALLBACK',
    contentType: "application/json",
    dataType: 'jsonp',
    success: function(data) {
      $("table>tbody").html(tableTemplate({
        countries: data
      }));
    },
    error: function(e) {
      console.log(e.message);
    }
  });
});

table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

<table>
  <thead>
    <tr>
      <th>Country</th>
      <th>Population</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

<script type="text/html" id='table-data'>
  <% _.each(countries, function(country, key, list){ %>
    <tr>
      <td> <%= country.name %> </td>
      <td> <%= country.population %> </td>
    </tr>
    <% }) %>
</script>

使用ExtJS（4.2）

的解决方案

我继续使用Ext JS创建了一个解决方案。

Ext.onReady(function() {
  var tpl = new Ext.XTemplate(
    '<table class="view_table">',
      '<thead>',
        '<tr>',
          '<th>Name</th>',
          '<th>Population</th>',
        '</tr>',
      '</thead>',
      '<tbody>',    
        '<tpl for=".">',    
          '<tr>',
            '<td>{name}</td>',
            '<td>{population}</td>',
          '</tr>',
        '</tpl>', 
      '</tbody>',
    '</table>'
  );
  
  Ext.data.JsonP.request({
    url: 'http://beta.json-generator.com/api/json/get/CK4M2Hk',
    params : {
      callback : 'Ext.data.JsonP.callback1'
    },
    method: 'GET',
    callback: function(success, response, data) {
      Ext.get(Ext.dom.Query.select('#country-grid')).setHTML(tpl.apply(response));
    }
  });
});

body {
  background: #FFF !important;
}
table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/extjs/4.2.1/ext-all.min.js"></script>

<div id="country-grid"></div>

使用ExtJS（4.2）使用DataView

的解决方案

这是一个更先进，更完整的ExtJS模板示例。 DataView，Model和Store用于存储和显示模板中的数据。

var jsonDataUrl = 'http://beta.json-generator.com/api/json/get/CK4M2Hk?indent=2&callback=Ext.data.JsonP.callback1';

Ext.onReady(function() {
  Ext.define('app.model.Country', {
    extend: 'Ext.data.Model',
    fields: [{
      name: 'name',
      type: 'string'
    }, {
      name: 'population',
      type: 'int'
    }]
  });

  Ext.create('Ext.data.Store', {
    storeId: 'countryStore',
    model: 'app.model.Country',
    autoLoad: true,
    proxy: {
      type: 'jsonp',
      url: jsonDataUrl,
      reader: {
        type: 'json'
      }
    }
  });

  var tpl = new Ext.XTemplate(
    '<table class="view_table">',
      '<thead>',
        '<tr>',
          '<th>Name</th>',
          '<th>Population</th>',
        '</tr>',
      '</thead>',
      '<tbody>',    
        '<tpl for=".">',    
          '<tr>',
            '<td>{name}</td>',
            '<td>{population}</td>',
          '</tr>',
        '</tpl>', 
      '</tbody>',
    '</table>'
  );
  
  Ext.create('Ext.DataView', {
    width    : 500,
    height   : 200,
    renderTo : 'countryApp',
    store    : Ext.getStore('countryStore'),
    tpl      : tpl    
  });
});

body {
  background: #FFF !important;
}
table {
  background: #DDD;
}
thead tr {
  background: #9D9;
}
tbody tr:nth-child(2n) {
  background: #CFC;
}
tbody tr:nth-child(2n+1) {
  background: #EFE;
}
th, td {
  width: 100px;
  padding: 0.2em;
  text-align: center;
}

使用此生成器函数生成JSON数据：http://beta.json-generator.com/CK4M2Hk

Answer 2

第1步

转到http://myjson.com/

我粘贴在我的json数据中并点击保存然后我会得到一个链接：

<强> https://api.myjson.com/bins/3ffb0

enter image description here

第2步

现在我有了这个URL，我就像这样使用它

    $http.get('https://api.myjson.com/bins/3ffb0').success(function(data) {
      $scope.countries = data;
    });

My Result

像魅力一样工作。没有抱怨。：d

Answer 3

您也可以将此json放入服务器上的文件中，然后使用script代码加载它。

<script src="my.js"></script>

在您使用它的脚本之前加载此文件。

my.js

var myJson = [{.....}]; // My long json

Answer 4

您无法将本地创建的.json文件加载到Fiddler中。

这里我放了一个我在网上找到的.json文件，你可以看到数据来自它（也进入控制台）。

https://jsfiddle.net/v99e25r8/

$http.get('https://json-generator.appspot.com/api/json/get/bVQoKFSGNu?indent=2')
    .success(function(data) {
        console.log(data);
        $scope.countries = data;
    });

Fiddler除外，如果这是在您的项目中，您只需要指向正确的目录。

Answer 5

您实际上可以在the jsfiddle documentation中使用本地创建的json：

new Request.JSON({
    url: '/echo/json/',
    data: {
        json: JSON.encode({
            text: 'some text',
            array: [1, 2, 'three'],
            object: {
                par1: 'another text',
                par2: [3, 2, 'one'],
                par3: {}
            }
        }),
        delay: 3
    },
    onSuccess: function(response) {
        show_response(response, $('post'));
    }
}).send();

show_response = function(obj, result) {
    $H(obj).each(function(v, k) {
        new Element('li', {
            text: k + ': ' + v
        }).inject(result);
    });
    result.highlight();
};

这不是我的代码，无论如何都是他们的小提琴;）在这里：

EDIT2

如何在我的代码中使用您的代码？

好吧，你可以实际使用他们的代码，因为你的目标是使用jsfiddle。这是json的一部分：

http://jsfiddle.net/QsHw4/6348/

我将ul变成了这样的表：

<table>
    <thead>
        <tr>
            <th>Country</th>
            <th>Population</th>
        </tr>
    </thead>
    <tbody id="post">
        <tr>
            <td>Lalaland</td>
            <td>0</td>
        </tr>
    </tbody>
</table>

这是Polywhirl先生CSS表的小提琴; P

http://jsfiddle.net/QsHw4/6351/

Answer 6

如果您将JSON文件放在GitHub中，您也可以Pass response directly from GitHub Repository。

您的JSON文件必须命名为demo.response.json并将其命名为

<强> /gh/get/response.json/ {github_tree} /

例如我在这里有JSON文件

https://github.com/chetabahana/chetabahana.github.io/blob/master/_data/demo.response.json

然后在 JSFiddle 中，您可以使用Ajax获取数据，如下所示：

<强> HTML

<p>Result will appear below with 1 sec delay</p>
<div id="demo"><p>This text will be replaced</p></div>

JS （选择 Mootools 框架之一）

window.addEvent('domready', function() {
    new Request.HTML({
        url: '/gh/get/response.json/chetabahana/chetabahana.github.io/tree/master/_data/',
        data: {'delay': 1},
        method: 'post',
        update: 'demo',
        onSuccess: function(response) {
            $('demo').highlight();
        }
    }).send();
})

注意：没有提供JSONP功能。可以使用 raw GitHub URL 来实现它。
