javascript - from - populate table with json data jquery




Convert JSON array to an HTML table in jQuery (9)

Converting a 2D JavaScript array to an HTML table

To turn a 2D JavaScript array into an HTML table, you really need but a little bit of code :

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>

Loading a JSON file

If you want to load your 2D array from a JSON file, you'll also need a little bit of Ajax code :

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

Is there a really easy way I can take an array of JSON objects and turn it into an HTML table, excluding a few fields? Or am I going to have to do this manually?


A still shorter way

$.makeTable = function (mydata) {
            if (mydata.length <= 0) return "";
           return $('<table border=1>').append("<tr>" + $.map(mydata[0], function (val, key) {
                return "<th>" + key + "</th>";
            }).join("\n") + "</tr>").append($.map(mydata, function (index, value) {
                return "<tr>" + $.map(index, function (val, key) {
                    return "<td>" + val + "</td>";
                }).join("\n") + "</tr>";
            }).join("\n"));
        };

I found a duplicate over here: Convert json data to a html table

Well, there are many plugins exists, including commercial one (Make this as commercial project?! Kinda overdone... but you can checkout over here: https://github.com/alfajango/jquery-dynatable)

This one has more fork: 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"
        }]
    }
}];

Apply the code

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

Or you might want to checkout this jQuery plugins as well: https://github.com/jongha/jquery-jsontotable

I think jongha's plugins is easier to use

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

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

I'm not sure if is this that you want but there is jqGrid. It can receive JSON and make a grid.


Make a HTML Table from a JSON array of Objects by extending $ as shown below

$.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));
};

and use as follows:

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

where TableCont is some div


Modified a bit code of @Dr.sai 's code. Hope this will be useful.

(function ($) {
    /**
     * data - array of record
     * hidecolumns, array of fields to hide
     * usage : $("selector").generateTable(json, ['field1', 'field5']);
     */
    'use strict';
    $.fn.generateTable = function (data, hidecolumns) {
        if ($.isArray(data) === false) {
            console.log('Invalid Data');
            return;
        }
        var container = $(this),
            table = $('<table>'),
            tableHead = $('<thead>'),       
            tableBody = $('<tbody>'),       
            tblHeaderRow = $('<tr>');       

        $.each(data, function (index, value) {
            var tableRow = $('<tr>').addClass(index%2 === 0 ? 'even' : 'odd');      
            $.each(value, function (key, val) {
                if (index == 0 && $.inArray(key, hidecolumns) <= -1 ) { 
                    var theaddata = $('<th>').text(key);
                    tblHeaderRow.append(theaddata); 
                }
                if ($.inArray(key, hidecolumns) <= -1 ) { 
                    var tbodydata = $('<td>').text(val);
                    tableRow.append(tbodydata);     
                }
            });
            $(tableBody).append(tableRow);  
        });
        $(tblHeaderRow).appendTo(tableHead);
        tableHead.appendTo(table);      
        tableBody.appendTo(table);
        $(this).append(table);    
        return this;
    };
})(jQuery);

Hoping this will be helpful to hide some columns too. Link to file


Pure HTML way, not vulnerable like the others AFAIK:

// 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);
}

Example usage:

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

Using jQuery will make this simpler.

The following will take an array of arrays and store convert them into rows and cells.

$.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);
});

You could add a check for the keys you want to exclude by adding something like

var expected_keys = { key_1 : true, key_2 : true, key_3 : false, key_4 : true };

at the start of the getJSON cbf and adding

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

around the tbl_row += line.

Edit: Was assigning a null variable previously

Edit: Version based on Timmmm's injection-free contribution.

$.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);
});

with pure jquery:

window.jQuery.ajax({
    type: "POST",
    url: ajaxUrl,
    contentType: 'application/json',
    success: function (data) {

        var odd_even = 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);
    }
});
