是否有任何 jQuery 或 javascript 库可以生成给定 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，生成html表。我只想知道是否存在任何可以简单重用的此类库。

谢谢大家的回复。我自己写了一篇。请注意，这使用了 jQuery。
代码片段：
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;

<body onLoad="buildHtmlTable('#excelDataTable')">
<table id="excelDataTable" border="1">
</table>
</body>我已经在 vanilla-js 中重写了您的代码，使用 DOM 方法来防止 html 注入。
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;
}
document.body.appendChild(buildHtmlTable([{
"name": "abc",
"age": 50
},
{
"age": "25",
"hobby": "swimming"
},
{
"name": "xyz",
"hobby": "programming"
}
]));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
$("#tbody").jPut({
jsonData:json,
//ajax_url:"youfile.json", if you want to call from a json file
name:"tbody_template",
});
});
</script>
<table jput="t_template">
<tbody jput="tbody_template">
<tr>
<td>{{name}}</td>
<td>{{email}}</td>
</tr>
</tbody>
</table>
<table>
<tbody id="tbody">
</tbody>
</table>
查看JSON2HTML http://json2html.com/ jQuery 插件。它允许您指定将您的 JSON 对象转换为 HTML 模板的转换。使用http://json2html.com/上的构建器为任何所需的 html 模板获取 json 转换对象。在您的情况下，它将是一个具有以下转换的行的表。
例子：
var transform = {"tag":"table", "children":[
{"tag":"tbody","children":[
{"tag":"tr","children":[
{"tag":"td","html":"${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));
