<tr class="alt">
    <td class="status"><input type="text" value="One"></td>
    <td class>Received</td>
</tr>
<tr class="alt">
    <td class="status"><input type="text" value="One"></td>
    <td class>Received</td>
</tr>
<tr class="alt">
    <td class="status"><input type="text" value="Zero"></td>
    <td class>Received</td>
</tr>
<tr class="alt">
    <td class="status"><input type="text" value="One"></td>
    <td class>Received</td>
</tr>
<tr class="alt">
    <td class="status"><input type="text" value="Zero"></td>
    <td class>Received</td>
</tr>

$(document).ready(function()
{
$("tr.alt:even").css("background-color", "#f0f8ff");
$("tr.alt:odd").css("background-color", "#fcfceb");
});

$(document).ready(function() {
   $('.status.val():contains("Zero")').closest('tr.alt').css('background-color', '#cd0000');
});

I wanna change the row color based on the input value

我想根据输入值改变行颜色。

<td class="status"><input type="text" value="One"></td>

< td类= "地位" > < input type = "文本" value = " 1 " > < / td >

Here is a fiddle of what I've done so far

这是我迄今为止所做的一件事。

Would appreciate the help.

To change the tr (you're using v 1.6.4 instead of latest so we need bind instead of on)

要更改tr(您使用的是v1.6.4而不是最新版本，所以我们需要bind而不是on)

$(document).ready(function(){

    $("tr.alt:even").addClass("even");
    $("tr.alt:odd").addClass("odd");
    $('td.status input').bind('change keyup', function(){
        var tr=$(this).closest('tr');

        if ($(this).val()=='Zero') tr.addClass('zero');       
        else tr.removeClass('zero');

    }).trigger('change'); // the trigger is to run this action on load
});
​
tr.odd
{
    background-color:#fcfceb;
}

tr.even
{
    background-color:#f0f8ff;
}

tr.odd.zero
{
    background-color:#ff0000;
}
tr.even.zero
{
    background-color:#cc0000;
}

Your HTML is a bit messed up though. You have missing quotes and <td class> is invalid.

你的HTML有点混乱。您丢失了引号，并且

EDIT: Updated version to suit the values being changed manually, not just those that are outputted (as I understood the question to be)

编辑:更新版本以适应手动更改的值，而不仅仅是输出的值(正如我理解的那样)

You'll see I moved the background colours out of the HTML and into the CSS to make it easier to manipulate. I also adjusted the red for even or odd rows.

您将看到，我将背景颜色从HTML移到了CSS中，以便更容易操作。我还调整了偶数或奇数行的红色。
