How can get row number in HTML table using jQuery?

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().


If you can, it might be worth using a class attribute on the TD containing the customer ID so you can write:

$('#mytable tr').each(function() {
    var customerId = $(this).find(".customerIDCell").html();    
 });

Essentially this is the same as the other solutions (possibly because I copy-pasted), but has the advantage that you won't need to change the structure of your code if you move around the columns, or even put the customer ID into a <span>, provided you keep the class attribute with it.

By the way, I think you could do it in one selector:

$('#mytable .customerIDCell').each(function() {
  alert($(this).html());
});

If that makes things easier.


$('#mytable tr').each(function() {
    var customerId = $(this).find("td:first").html();    
});

What you are doing is iterating through all the trs in the table, finding the first td in the current tr in the loop, and extracting its inner html.

To select a particular cell, you can reference them with an index:

$('#mytable tr').each(function() {
    var customerId = $(this).find("td").eq(2).html();    
});

In the above code, I will be retrieving the value of the third row (the index is zero-based, so the first cell index would be 0)


Here's how you can do it without jQuery:

var table = document.getElementById('mytable'), 
    rows = table.getElementsByTagName('tr'),
    i, j, cells, customerId;

for (i = 0, j = rows.length; i < j; ++i) {
    cells = rows[i].getElementsByTagName('td');
    if (!cells.length) {
        continue;
    }
    customerId = cells[0].innerHTML;
}


a less-jquerish approach:

$('#mytable tr').each(function() {
    if (!this.rowIndex) return; // skip first row
    var customerId = this.cells[0].innerHTML;
});

this can obviously be changed to work with not-the-first cells.


$('#mytable tr').each(function() {
  // need this to skip the first row
  if ($(this).find("td:first").length > 0) {
    var cutomerId = $(this).find("td:first").html();
  }
});

Try this,

$(document).ready(function(){
$(".items").delegate("tr.classname", "click", function(data){
            alert(data.target.innerHTML);//this will show the inner html
    alert($(this).find('td:eq(0)').html());//this will alert the value in the 1st column.
    });
});
