how to find smallest value of td :contains(textbox) using jquery

How do I get smallest value开发者_StackOverflow社区 of the textbox using jquery? rows means trs which contain multiple tds & tds in turn contains textboxes I want to find the smallest value of each tr

 $.each(rows, function () {
             $(this).find("input[type='text']") //find smallest value of the textbox
    });

how can I achieve this?

You can build an array of the smallest <input> values in each <tr> using .map(). Assuming you want to interpret each value as a number:

var minValues = $(rows).map(function ()
{
    var rowVals = $(this).find('input:text').map(function ()
    {
        return Number($(this).val());
    }).get();

    return Math.min.apply(null, rowVals);
}).get();

API docs:

• .map()
• :text selector
• .val()
• Math.min
• Function.apply

If you don't need to use the array as a whole, and just iterate over the minimum values:

$(rows).each(function ()
{
    var rowVals = $(this).find('input:text').map(function ()
    {
        return Number($(this).val());
    }).get();

    var min = Math.min.apply(null, rowVals);

    // do stuff with min
})

You're almost there. Here's what I did:

$.each(rows, function () {
    var sorted = $(this).find("input[type='text']").sort(
        function(a, b) { return a.value - b.value }
    );
    var lowest = sorted[0].value;
});
