calculate only selected input text with checkbox

Hi I need to calculate the sum from m开发者_运维问答ultiple selected input text form, that are selected with checkbox like this:

<input type="text" value="" name="satelitep">
<input type="checkbox" value="sateliteon" name="satelite">

How can i do this whit JavaScript or jQuery?

Thanks

You can select them and get the size:

var score = $("input:checkbox[checked=true]").size();

Try something like

var sum = 0;

$("input:checkbox [name='satelite']:checked").each(function(){
    sum += parseFloat($(this).prev().val());
});

Something like this should do the job.

var counter = 0;
$('input:checked').prev().each(function(index){
     counter += parseFloat(this.val());
});

It is untested, but should show the basic idea. It requires jQuery.

This finds all checked input fields, finds the fields immediately preceding them, then loops over each of them, adding their value to a counter.

Hope this helps
