Click table row and get value of all cells

There is no need to add ids or add multiple event handlers to the table. One click event is all that is needed. Also you should use thead and tbody for your tables to separate the heading from the content.

var table = document.getElementsByTagName("table")[0];
var tbody = table.getElementsByTagName("tbody")[0];
tbody.onclick = function (e) {
    e = e || window.event;
    var data = [];
    var target = e.srcElement || e.target;
    while (target && target.nodeName !== "TR") {
        target = target.parentNode;
    }
    if (target) {
        var cells = target.getElementsByTagName("td");
        for (var i = 0; i < cells.length; i++) {
            data.push(cells[i].innerHTML);
        }
    }
    alert(data);
};
<table class='list'>
    <thead>
        <tr>
            <th class='tech'>OCB</th>
            <th class='area'>Area</th>
            <th class='name'>Name</th>
            <th class='cell'>Cell #</th>
            <th class='nick'>Nickname</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>275</td>
            <td>Layton Installation</td>
            <td>Benjamin Lloyd</td>
            <td>(801) 123-456</td>
            <td>Ben</td>
        </tr>
    </tbody>
</table>
