我是否有一种非常简单的方法可以获取一组JSON对象并将其转换为HTML表,不包括几个字段?或者我是否必须手动执行此操作?

使用jQuery会使这更简单。

以下将采用数组数组并将它们转换为行和单元格。

$.getJSON(url , function(data) {
    var tbl_body = "";
    var odd_even = false;
    $.each(data, function() {
        var tbl_row = "";
        $.each(this, function(k , v) {
            tbl_row += "<td>"+v+"</td>";
        })
        tbl_body += "<tr class=\""+( odd_even ? "odd" : "even")+"\">"+tbl_row+"</tr>";
        odd_even = !odd_even;               
    })
    $("#target_table_id tbody").html(tbl_body);
});

您可以通过添加类似

的内容添加对要排除的键的检查
var expected_keys = { key_1 : true, key_2 : true, key_3 : false, key_4 : true };
在getJSON cbf的开头并添加

if ( ( k in expected_keys ) && expected_keys[k] ) {
...
}

围绕tbl_row + =行。

编辑:之前正在分配一个空变量

修改:版本基于Timmmminjection-free贡献。

$.getJSON(url , function(data) {
    var tbl_body = document.createElement("tbody");
    var odd_even = false;
    $.each(data, function() {
        var tbl_row = tbl_body.insertRow();
        tbl_row.className = odd_even ? "odd" : "even";
        $.each(this, function(k , v) {
            var cell = tbl_row.insertCell();
            cell.appendChild(document.createTextNode(v.toString()));
        })        
        odd_even = !odd_even;               
    })
    $("#target_table_id").appendChild(tbl_body);
});

我不确定这是否是您想要的,但有jqGrid。它可以接收JSON并制作网格。

答案 2 :(得分:13)

通过扩展$,从JSON对象数组中创建一个HTML表,如下所示

$.makeTable = function (mydata) {
    var table = $('<table border=1>');
    var tblHeader = "<tr>";
    for (var k in mydata[0]) tblHeader += "<th>" + k + "</th>";
    tblHeader += "</tr>";
    $(tblHeader).appendTo(table);
    $.each(mydata, function (index, value) {
        var TableRow = "<tr>";
        $.each(value, function (key, val) {
            TableRow += "<td>" + val + "</td>";
        });
        TableRow += "</tr>";
        $(table).append(TableRow);
    });
    return ($(table));
};

并使用如下:

var mydata = eval(jdata);
var table = $.makeTable(mydata);
$(table).appendTo("#TableCont");

其中TableCont是div

纯HTML方式,不像其他AFAIK那样脆弱:

// Function to create a table as a child of el.
// data must be an array of arrays (outer array is rows).
function tableCreate(el, data)
{
    var tbl  = document.createElement("table");
    tbl.style.width  = "70%";

    for (var i = 0; i < data.length; ++i)
    {
        var tr = tbl.insertRow();
        for(var j = 0; j < data[i].length; ++j)
        {
            var td = tr.insertCell();
            td.appendChild(document.createTextNode(data[i][j].toString()));
        }
    }
    el.appendChild(tbl);
}

使用示例:

$.post("/whatever", { somedata: "test" }, null, "json")
.done(function(data) {
    rows = [];
    for (var i = 0; i < data.Results.length; ++i)
    {
        cells = [];
        cells.push(data.Results[i].A);
        cells.push(data.Results[i].B);
        rows.push(cells);
    }
    tableCreate($("#results")[0], rows);
});

将2D JavaScript数组转换为HTML表

要将2D JavaScript数组转换为HTML表,您只需要一些代码:

function arrayToTable(tableData) {
    var table = $('<table></table>');
    $(tableData).each(function (i, rowData) {
        var row = $('<tr></tr>');
        $(rowData).each(function (j, cellData) {
            row.append($('<td>'+cellData+'</td>'));
        });
        table.append(row);
    });
    return table;
}

$('body').append(arrayToTable([
    ["John","Slegers",34],
    ["Tom","Stevens",25],
    ["An","Davies",28],
    ["Miet","Hansen",42],
    ["Eli","Morris",18]
]));
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

加载JSON文件

如果要从JSON文件加载2D数组,还需要一些Ajax代码:

$.ajax({
    type: "GET",
    url: "data.json",
    dataType: 'json',
    success: function (data) {
        $('body').append(arrayToTable(data));
    }
});

对于非常高级的JSON对象到HTML表格,您可以尝试基于此My jQuery Solutionclosed thread

var myList=[{"name": "abc","age": 50},{"name": {"1": "piet","2": "jan","3": "klaas"},"age": "25","hobby": "watching tv"},{"name": "xyz","hobby": "programming","subtable": [{"a": "a","b": "b"},{"a": "a","b": "b"}]}];

// Builds the HTML Table out of myList json data from Ivy restful service.
 function buildHtmlTable() {
      addTable(myList, $("#excelDataTable"));
 }

function addTable(list, appendObj) {
    var columns = addAllColumnHeaders(list, appendObj);

    for (var i = 0; i < list.length; i++) {
        var row$ = $('<tr/>');
        for (var colIndex = 0; colIndex < columns.length; colIndex++) {
            var cellValue = list[i][columns[colIndex]];

            if (cellValue == null) {
                cellValue = "";
            }

            if (cellValue.constructor === Array)
            {
                $a = $('<td/>');
                row$.append($a);
                addTable(cellValue, $a);

            } else if (cellValue.constructor === Object)
            {

                var array = $.map(cellValue, function (value, index) {
                    return [value];
                });

                $a = $('<td/>');
                row$.append($a);
                addObject(array, $a);

            } else {
                row$.append($('<td/>').html(cellValue));
            }
        }
        appendObj.append(row$);
    }
}


function addObject(list, appendObj) {
    for (var i = 0; i < list.length; i++) {
        var row$ = $('<tr/>');

        var cellValue = list[i];

        if (cellValue == null) {
            cellValue = "";
        }

        if (cellValue.constructor === Array)
        {
            $a = $('<td/>');
            row$.append($a);
            addTable(cellValue, $a);

        } else if (cellValue.constructor === Object)
        {

            var array = $.map(cellValue, function (value, index) {
                return [value];
            });

            $a = $('<td/>');
            row$.append($a);
            addObject(array, $a);

        } else {
            row$.append($('<td/>').html(cellValue));
        }
        appendObj.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(list, appendObj)
{
    var columnSet = [];
    var headerTr$ = $('<tr/>');

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

    return columnSet;
}

您可以使用接受JSON数据的jQuery插件来填充表格。 jsonTable

答案 7 :(得分:1)

我在这里发现了一个副本:Convert json data to a html table

嗯,有很多插件存在,包括商业插件(将其设为商业项目?!有点过头......但你可以在这里结账:https://github.com/alfajango/jquery-dynatable

这个有更多的分叉:https://github.com/afshinm/Json-to-HTML-Table

//Example data, Object 
var objectArray = [{
    "Total": "34",
    "Version": "1.0.4",
    "Office": "New York"
}, {
    "Total": "67",
    "Version": "1.1.0",
    "Office": "Paris"
}];

//Example data, Array
var stringArray = ["New York", "Berlin", "Paris", "Marrakech", "Moscow"];

//Example data, nested Object. This data will create nested table also.
var nestedTable = [{
    key1: "val1",
    key2: "val2",
    key3: {
        tableId: "tblIdNested1",
        tableClassName: "clsNested",
        linkText: "Download",
        data: [{
            subkey1: "subval1",
            subkey2: "subval2",
            subkey3: "subval3"
        }]
    }
}];

应用代码

//Only first parameter is required
var jsonHtmlTable = ConvertJsonToTable(objectArray, 'jsonTable', null, 'Download');

或者你也可以查看这个jQuery插件:https://github.com/jongha/jquery-jsontotable

我认为jongha的插件更易于使用

<div id="jsontotable" class="jsontotable"></div>

var data = [[1, 2, 3], [1, 2, 3]];
$.jsontotable(data, { id: '#jsontotable', header: false });

        var response = JSON.parse(data);

        var head = "<thead class='thead-inverse'><tr>";
        $.each(response[0], function (k, v) {
            head = head + "<th scope='row'>" + k.toString() + "</th>";
        })
        head = head + "</thead></tr>";
        $(table).append(head);//append header
       var body="<tbody><tr>";
        $.each(response, function () {
            body=body+"<tr>";
            $.each(this, function (k, v) {
                body=body +"<td>"+v.toString()+"</td>";                                        
            }) 
            body=body+"</tr>";               
        })
        body=body +"</tbody>";
        $(table).append(body);//append body
    },
    error: function (xhr, ajaxOptions, thrownError) {
        alert(xhr.responsetext);
    }
});

如果您接受使用其他 jQuery 依赖工具,我建议您使用Tabulator。然后,您将不需要编写HTML或任何其他DOM生成代码,同时在表格数据的格式化和处理方面保持极大的灵活性。
