I'm trying to use closest() to get <input> element which is in different div. Here's the markup:

<div class="row">
    <div class="span8">
        <input type="text" disabled="disabled" id="image-name">
    </div>
    <div class="span4">
        <input type="file">
    </div>
</div>

Here's the script

$(document).ready(function(){
    $("input:file").change(function (){
       var fileName = $(this).val();
       //Put the file name inside the disabled <input>
       $(this).closest('input:disabled').val(fileName);
    });
});

It doesn't do anything though. I tried changing input:disabled to #image-name but still doesn't work.

Any solution?

Thanks

If you have an id on the other INPUT element, why are you using the closest function? Why not just $('#image-name')? The closest method does not work the way you think. closest always goes up the DOM tree until it finds a match.

Based on the ment to my initial suggestion, you could get DRY by using the more fancy versions of the jQuery event binders:

function handler(e, args) {
    $(e.data.elem).val(fileName);
}

$('input:file').bind('change', { elem: '#image-name' }, handler);
$('#other-input').bind('change', { elem: '#other-field' }, handler);

reusable event handler parameterized using event data constructs.

Because closest travels upwards, not sideways. Just to add, it starts matching the current element as well.

A more generic way is to use closest to find the mon ancestor, which is .row, and find the disabled text box from there. You could also do parent, prev and children, assuming the HTML is always that way.

You can use:

$(this).closest('.row').find('input:disabled').val(fileName);

since closest() will traverse up through its ancestors in the DOM tree.

Use closest to get to the root parent , then use find.

$(this).closest('.row').find('input[disabled]').val(fileName);

Try this

Just now noticed your input has ID so you could just do $('#image-name').val(fileName)
