Convert JSON array to an HTML table in jQuery

Question

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?

Answer 1

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

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);
});
