将json数据转换为html表

时间:2011-03-03 11:54:35

标签: javascript html json html-table

是否有任何jQuery或javascript库生成给定json数据的动态表? 我不想定义列,库应该读取json哈希中的键并生成列。

当然,我可以自己遍历json数据并生成html表。我只是想知道是否存在任何我可以简单重用的库。

感谢大家的回复。 I wrote one myself.请注意,这使用jQuery。

代码段:

var myList = [
  { "name": "abc", "age": 50 },
  { "age": "25", "hobby": "swimming" },
  { "name": "xyz", "hobby": "programming" }
];

// Builds the HTML Table out of myList.
function buildHtmlTable(selector) {
  var columns = addAllColumnHeaders(myList, selector);

  for (var i = 0; i < myList.length; i++) {
    var row$ = $('<tr/>');
    for (var colIndex = 0; colIndex < columns.length; colIndex++) {
      var cellValue = myList[i][columns[colIndex]];
      if (cellValue == null) cellValue = "";
      row$.append($('<td/>').html(cellValue));
    }
    $(selector).append(row$);
  }
}

// Adds a header row to the table and returns the set of columns.
// Need to do union of keys from all records as some records may not contain
// all records.
function addAllColumnHeaders(myList, selector) {
  var columnSet = [];
  var headerTr$ = $('<tr/>');

  for (var i = 0; i < myList.length; i++) {
    var rowHash = myList[i];
    for (var key in rowHash) {
      if ($.inArray(key, columnSet) == -1) {
        columnSet.push(key);
        headerTr$.append($('<th/>').html(key));
      }
    }
  }
  $(selector).append(headerTr$);

  return columnSet;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<body onLoad="buildHtmlTable('#excelDataTable')">
  <table id="excelDataTable" border="1">
  </table>
</body>

我已经用vanilla-js重写了你的代码,使用DOM方法来防止html注入。

Demo

var _table_ = document.createElement('table'),
    _tr_ = document.createElement('tr'),
    _th_ = document.createElement('th'),
    _td_ = document.createElement('td');

// Builds the HTML Table out of myList json data from Ivy restful service.
 function buildHtmlTable(arr) {
     var table = _table_.cloneNode(false),
         columns = addAllColumnHeaders(arr, table);
     for (var i=0, maxi=arr.length; i < maxi; ++i) {
         var tr = _tr_.cloneNode(false);
         for (var j=0, maxj=columns.length; j < maxj ; ++j) {
             var td = _td_.cloneNode(false);
                 cellValue = arr[i][columns[j]];
             td.appendChild(document.createTextNode(arr[i][columns[j]] || ''));
             tr.appendChild(td);
         }
         table.appendChild(tr);
     }
     return table;
 }

 // Adds a header row to the table and returns the set of columns.
 // Need to do union of keys from all records as some records may not contain
 // all records
 function addAllColumnHeaders(arr, table)
 {
     var columnSet = [],
         tr = _tr_.cloneNode(false);
     for (var i=0, l=arr.length; i < l; i++) {
         for (var key in arr[i]) {
             if (arr[i].hasOwnProperty(key) && columnSet.indexOf(key)===-1) {
                 columnSet.push(key);
                 var th = _th_.cloneNode(false);
                 th.appendChild(document.createTextNode(key));
                 tr.appendChild(th);
             }
         }
     }
     table.appendChild(tr);
     return columnSet;
 }

您可以使用简单的jQuery jPut插件

http://plugins.jquery.com/jput/

<script>
$(document).ready(function(){

var json = [{"name": "name1","email":"email1@domain.com"},{"name": "name2","link":"email2@domain.com"}];
//while running this code the template will be appended in your div with json data
$("#tbody").jPut({
    jsonData:json,
    //ajax_url:"youfile.json",  if you want to call from a json file
    name:"tbody_template",
});

});
</script>   

<table jput="t_template">
 <tbody jput="tbody_template">
     <tr>
         <td>{{name}}</td>
         <td>{{email}}</td>
     </tr>
 </tbody>
</table>

<table>
 <tbody id="tbody">
 </tbody>
</table>

查看jQuery的 JSON2HTML http://json2html.com/插件。它允许您指定将JSON对象转换为HTML模板的转换。使用http://json2html.com/上的构建器来获取任何所需html模板的json变换对象。在您的情况下,它将是一个具有后续转换行的表。

示例:

var transform = {"tag":"table", "children":[
    {"tag":"tbody","children":[
        {"tag":"tr","children":[
            {"tag":"td","html":"${name}"},
            {"tag":"td","html":"${age}"}
        ]}
    ]}
]};

var data = [
    {'name':'Bob','age':40},
    {'name':'Frank','age':15},
    {'name':'Bill','age':65},
    {'name':'Robert','age':24}
];

$('#target_div').html(json2html.transform(data,transform));
