Question

I have an id for a <tr id="tagTR">
Given the above, is it possible to find the next input:text element regardless of any other mark up in between . Is there a jQuery selector that I can use for this scenario?

For example :

<tr id="tagTR"> 
</tr>
<tr id="tagRed"> 

  <td> </td>
</tr>
<div>
 <tr>
   <td>
     <input> // This is what I want to get to. 
   </td>
 </tr>
</div>

I thought this question was very interesting. It seems others are reading this as, find the next input among siblings. But I read it as – find me the next input no matter what. I don’t know if its in a sibling, a parent or a parent’s sibling. This is what I came up with based on feedback I received from this question.

//assume you know where you are starting from
var $startElement = $('#foo');

//get all text inputs
var $inputs = $('input[type=text]');

//search inputs for one that comes after starting element
for (var i = 0; i < $inputs.length; i++) {
    if (isAfter($inputs[i], $startElement)) {
        var nextInput = $inputs[i];
        alert($(nextInput).val());
    }
}

//is element before or after
function isAfter(elA, elB) {
    return ($('*').index($(elA).last()) > $('*').index($(elB).first()));
}
