Mais je ne peux pas comprendre comment obtenir les entrées de la même ligne i cliqué

$('input[type=image]').click(function(){ 
    // insert voodoo go get inputs here 
    // ajax call 
    return false; 
}); 

Je ne peux pas faire quelque chose comme $ (entrée [name = "code-barres"]) Toutes les idées?

Answer 1

vous devez faire qqch comme:

$('input[type=image]').click(function(){ 
    var image = $(this); 
    var parent = image.parent(); // this will be the fieldset, could also do .closest('fieldset)', if the fieldset is not the immediate parent 
    var neededInput = $('input[name=barcode]', parent); 
    // do something with it 
    return false; 
}); 

ou en utilisant la siblings() -method

$('input[type=image]').click(function (event){ 
    event.preventDefault(); 
    var $image = $(this); 
    var $neededInput = $image.siblings('input[name=barcode]'); 
    // do something with it 
}); 

Answer 2

dans votre fonction de clic, this sera une référence à l'image que vous avez cliqué. Ainsi, vous pouvez faire

$(this).siblings() 

ou

$(this).closest('fieldset').find(...);
