Tips for inserting information into data tables

Let me begin by outlining the process I am undertaking. I interact with a remote JSON API to retrieve data, perform some basic operations on it, and ultimately produce a data row consisting of three variables: Date, name, and message (think of an IRC chat room). My goal is to exhibit this information in a searchable data table, but I am encountering difficulties when attempting to add a row to said table. Presently, my HTML structure resembles the following:

<table id="table" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Date</th>
                <th>Name</th>
                <th>Message</th>
            </tr>
        </thead>

        <tfoot>
            <tr>
                <th>Date</th>
                <th>Name</th>
                <th>Message</th>
            </tr>
        </tfoot>
    </table>

In addition, here is an excerpt from my JavaScript code:

    var text = document.getElementById('text'); //Text Div
    var nameguest = data.items[i].from; //Guests
    var nameuser = data.items[i].from.name; //Users
    var message = data.items[i].message; //Messages
    changeDate(data.items[i].date); //Date
    var table = document.getElementById("table"); //Table Div

    var row = table.insertRow(i);
    row.insertCell(0).innerHTML = datehuman;
    if (typeof nameguest == "object") {
        row.insertCell(1).innerHTML = nameuser;
    } else {
        row.insertCell(1).innerHTML = nameguest;
    }
    row.insertCell(2).innerHTML = message;
}
}

I would like to inquire if there exists equivalent functionality akin to insertCell(0).innerHTML tailored for datatables?

To improve the structure of your table in HTML, remember to include an additional "tbody" tag. Use the provided function below to easily add new entries to your table.

function addRow (tableId, date, name, message) {

    var table = document.getElementById(tableId),
    tbody = table.getElementsByTagName("tbody")[0],
    tr = document.createElement("tr"),
    newDateEntry = document.createElement("td"),
    newNameEntry = document.createElement("td"),
    newMessageEntry = document.createElement("td");

    newDateEntry.innerHTML = date;
    newNameEntry.innerHTML = name;
    newMessageEntry.innerHTML = message;

    tr.appendChild(newDateEntry);
    tr.appendChild(newNameEntry);
    tr.appendChild(newMessageEntry);

    tbody.appendChild(tr);
}

Your updated HTML code should resemble the example below:

<table id="table" class="display" cellspacing="0" width="100%">
    <thead>
        <tr>
            <th>Date</th>
            <th>Name</th>
            <th>Message</th>
        </tr>
    </thead>
    <tbody></tbody>
    <tfoot>
        <tr>
            <th>Date</th>
            <th>Name</th>
            <th>Message</th>
        </tr>
    </tfoot>
</table>

To use the function, simply make a call like this:

addRow("table", "1/1/15", "JohnDoe", "Hello there");

Answer №2

Following your provided HTML code, I included a tbody tag as shown below:

<table id="table" class="display" cellspacing="0" width="100%">
    <thead>
        <tr>
            <th>Date</th>
            <th>Name</th>
            <th>Message</th>
        </tr>
    </thead>
<tbody></tbody>
    <tfoot>
        <tr>
            <th>Date</th>
            <th>Name</th>
            <th>Message</th>
        </tr>
    </tfoot>
</table>

To populate data in the table, you can utilize the append function in jQuery.

var nameUser = data.items[i].from.name; //Users    
var message = data.items[i].message; //Messages
var newRowContent = "<td>" + nameUser + "</td><td>" + message + "</td><td>" + changeDate(data.items[i].date) + "</td>"

$("#tblEntAttributes tbody").append(newRowContent);

In the above code snippet, I stored values in a variable and appended them to the table's tbody element.
