Menu
I need to count the number of text inputs with a value of 1.
I have tried the following but with no luck.
$('.class[value="1"]').length
$('.class:contains("1")').length
Using $('.class[value="1"]') technically works, however, if the values in the text input are changed after load, it still counts it as its default load value.
I took a long shot by using the .live click event to get the current value but still no luck.
I had no luck at all using $('.class:contains("1")')
It seems very simple, but has so far eluded me.

This example demonstrates that this works:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#btn").click(function() {
alert($(":input[value='1']").length);
});
});
</script>
</head>
<body>
<input type="text">
<input type="text">
<input type="text">
<input type="button" id="btn" value="How many?">
</body>
</html>
Alternatively you can just loop:
var matches = 0;
$(":input.class").each(function(i, val) {
if ($(this).val() == '1') {
matches++;
}
});
You need to iterate with $.each() if you want current val() values:
k=0;
$('.class').each(function(i, e) {
if ($(e).val() == "1") k++;
});
