本篇文章给大家介绍 html中美化展示json格式数据的方式。有一定的参考价值,有需要的朋友可以参考一下,希望对大家有所帮助。
直接上代码:
html中主要加一个pre 的标签
<h2>GeoJsonTxt示例如下:</h2> <p> <h4>注意:示例中<span style="color:red">features,geometry,coordinates,properties,name,description</span>字段是必须有的, 字段名称不能改变,需要扩展的字段可以在<span style="color:red">properties</span>里面自行添加</h4> </p> <pre id="geoJsonTxt">
js代码:
function showGeoJsonTxt(){ $('#geoJsonTxt').html(JsonFormat()); } function JsonFormat() { var json={ "type": "FeatureCollection", "features": [ { "type": "Feature", "geometry": { "type": "Point", "coordinates": [ 123, 22, 0 ] }, "properties": { "name": "必须有的字段", "description": "必须有的字段", "age":"扩展字段,可以自行添加,扩展", "type":"扩展字段,可以自行添加,扩展" } }, { "type": "Feature", "geometry": { "type": "Point", "coordinates": [ 123, 32, 0 ] }, "properties": { "name": "必须有的字段", "description": "必须有的字段", } } ] }; if (typeof json != 'string') { json = JSON.stringify(json, undefined, 2); } json = json.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>'); return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) { var cls = 'number'; if (/^"/.test(match)) { if (/:$/.test(match)) { cls = 'key'; } else { cls = 'string'; } } else if (/true|false/.test(match)) { cls = 'boolean'; } else if (/null/.test(match)) { cls = 'null'; } return '<span class="' + cls + '">' + match + '</span>'; }); }
CSS代码,显示的时候可以更加美化
<style> pre {outline: 1px solid #ccc; padding: 5px; margin: 5px; } .string { color: green; } .number { color: darkorange; } .boolean { color: blue; } .null { color: magenta; } .key { color: red; } </style>
效果如下:
