Convert html table to array in javascript

Answer 1

Here's one example of doing what you want.

var myTableArray = [];

$("table#cartGrid tr").each(function() {
    var arrayOfThisRow = [];
    var tableData = $(this).find('td');
    if (tableData.length > 0) {
        tableData.each(function() { arrayOfThisRow.push($(this).text()); });
        myTableArray.push(arrayOfThisRow);
    }
});

alert(myTableArray);

You could probably expand on this, say, using the text of the TH to instead create a key-value pair for each TD.

Since this implementation uses a multidimensional array, you can access a row and a td by doing something like this:

myTableArray[1][3] // Fourth td of the second tablerow
