代碼僅在jsfiddle中有效

Question

我的一些代碼有問題。 它只在jsfiddle中運行，我不知道為什么它在Codepen或文件中不起作用。

為什么此代碼僅在jsfiddle中有效？ 我在codepen和文件中嘗試了它，但沒有顯示任何內容http://jsfiddle.net/auagufL8/

<script src="http://code.highcharts.com/maps/highmaps.js"></script>
<script src="http://code.highcharts.com/maps/modules/exporting.js"></script>
<script src="http://code.highcharts.com/mapdata/countries/nl/nl-all.js">   </script>

<div id="container"></div>


$(function () {

// Prepare demo data
var data = [
    {
        "hc-key": "nl-fr",
        "value": 0
    },
    {
        "hc-key": "nl-gr",
        "value": 1
    },
    {
        "hc-key": "nl-fl",
        "value": 2
    },
    {

#container {
height: 500px; 
min-width: 310px; 
max-width: 800px; 
margin: 0 auto; 
}
.loading {
margin-top: 10em;
text-align: center;
color: gray;
}

Answer 1

要在瀏覽器中運行代碼，您需要將其放入<script> //Your code goes here </script>標記

Answer 2

這個->

#container {
    height: 500px; 
    min-width: 310px; 
    max-width: 800px; 
    margin: 0 auto; 
    }
    .loading {
    margin-top: 10em;
    text-align: center;
    color: gray;
    }

是CSS，必須在<style>標記內。

這個->

$(function () {

// Prepare demo data
var data = [
    {
        "hc-key": "nl-fr",
        "value": 0
    },
    {
        "hc-key": "nl-gr",
        "value": 1
    },
    {
        "hc-key": "nl-fl",
        "value": 2
    },
    {
        "hc-key": "nl-ze",
        "value": 3
    },
    {
        "hc-key": "nl-nh",
        "value": 4
    },
    {
        "hc-key": "nl-zh",
        "value": 5
    },
    {
        "hc-key": "nl-dr",
        "value": 6
    },
    {
        "hc-key": "nl-ge",
        "value": 7
    },
    {
        "hc-key": "nl-li",
        "value": 8
    },
    {
        "hc-key": "nl-ov",
        "value": 9
    },
    {
        "hc-key": "nl-nb",
        "value": 10
    },
    {
        "hc-key": "nl-ut",
        "value": 11
    }
];

// Initiate the chart
$('#container').highcharts('Map', {

    title : {
        text : 'Highmaps basic demo'
    },

    subtitle : {
        text : 'Source map: <a href="http://code.highcharts.com/mapdata/countries/nl/nl-all.js">The Netherlands</a>'
    },

    mapNavigation: {
        enabled: true,
        buttonOptions: {
            verticalAlign: 'bottom'
        }
    },

    colorAxis: {
        min: 0
    },

    series : [{
        data : data,
        mapData: Highcharts.maps['countries/nl/nl-all'],
        joinBy: 'hc-key',
        name: 'Random data',
        states: {
            hover: {
                color: '#BADA55'
            }
        },
        dataLabels: {
            enabled: true,
            format: '{point.name}'
        }
    }]
});
 });

是Javascript，必須在<script>標記內。

Answer 3

哦!

此代碼可完美地在任何地方使用。
要使其在Codepen中正常工作，您需要通過JS面板內的小齒輪添加所有JS資源，並檢查是否已選擇Latest version of jQuery 。 <script>標記在HTML面板中被忽略。

 $(function () { // Prepare demo data var data = [ {"hc-key": "nl-fr","value": 0}, {"hc-key": "nl-gr","value": 1}, {"hc-key": "nl-fl","value": 2}, {"hc-key": "nl-ze","value": 3}, {"hc-key": "nl-nh","value": 4}, {"hc-key": "nl-zh","value": 5}, {"hc-key": "nl-dr","value": 6}, {"hc-key": "nl-ge","value": 7}, {"hc-key": "nl-li","value": 8}, {"hc-key": "nl-ov","value": 9}, {"hc-key": "nl-nb","value": 10}, {"hc-key": "nl-ut","value": 11} ]; // Initiate the chart $('#container').highcharts('Map', { title : { text : 'Highmaps basic demo' }, subtitle : { text : 'Source map: <a href="http://code.highcharts.com/mapdata/countries/nl/nl-all.js">The Netherlands</a>' }, mapNavigation: { enabled: true, buttonOptions: { verticalAlign: 'bottom' } }, colorAxis: { min: 0 }, series : [{ data : data, mapData: Highcharts.maps['countries/nl/nl-all'], joinBy: 'hc-key', name: 'Random data', states: { hover: { color: '#BADA55' } }, dataLabels: { enabled: true, format: '{point.name}' } }] }); }); 

 #container { height: 500px; min-width: 310px; max-width: 800px; margin: 0 auto; } .loading { margin-top: 10em; text-align: center; color: gray; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://code.highcharts.com/maps/highmaps.js"></script> <script src="http://code.highcharts.com/maps/modules/exporting.js"></script> <script src="http://code.highcharts.com/mapdata/countries/nl/nl-all.js"></script> <div id="container"></div> 

Answer 4

將所有與CSS相關的文件放在單獨的.css文件中，或將其放在HTML文件中的標記下。 還要將所有腳本放入.js文件中，或將其嵌入HTML文件中的標簽下。
