I don't know JQuery, so I'm hoping there is a way to do this in pure Javascript.
I need to click on a table row and get the value of each cell in that row. Here is the format of my table:
<table class='list'>
<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>
<tr onclick="somefunction()">
<td>275</td>
<td>Layton Installation</td>
<td>Benjamin Lloyd</td>
<td>(801) 123-456</td>
<td>Ben</td>
</tr>
</table>
Is there anyway short of putting a unique ID to each cell?
You can use the Core/index function in a given context, for example you can check the index of the TD in it's parent TR to get the column number, and you can check the TR index on the Table, to get the row number: $('td'). click(function(){ var col = $(this). parent().
An HTML table consists of one <table> element and one or more <tr>, <th>, and <td> elements. The <tr> element defines a table row, the <th> element defines a table header, and the <td> element defines a table cell.
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>

<table id="rowCtr" class='list'>
<thead>
<tr>
<th class='tech'>OCB</th>
<th class='area'>Area</th>
<th class='name'>Name</th>
<th class='cell'>Cell #</th>

JAVASCRIPT:
init();
function init(){
addRowHandlers('rowCtr');
}
function addRowHandlers(tableId) {
if(document.getElementById(tableId)!=null){
var table = document.getElementById(tableId);
var rows = table.getElementsByTagName('tr');
var ocb = '';
var area = '';
var name = '';
var cell = '';
var nick = '';
for ( var i = 1; i < rows.length; i++) {
rows[i].i = i;
rows[i].onclick = function() {
ocb = table.rows[this.i].cells[0].innerHTML;
area = table.rows[this.i].cells[1].innerHTML;
name = table.rows[this.i].cells[2].innerHTML;
cell = table.rows[this.i].cells[3].innerHTML;
nick = table.rows[this.i].cells[4].innerHTML;
alert('ocb: '+ocb+' area: '+area+' name: '+name+' cell: '+cell+' nick: '+nick);
};
}
}
