jquery function not working on multiple rows - php

Question

I have a table generated by jQuery, and a function that triggers an event when pressing ENTER.
The table generates correctly, but the function only works in the first wor of the table.
My html for the table is as follows:
<table border="1" id="PlantillaTable" name="PlantillaTable">
<tbody>
<tr>
<th rowspan="2" scope="col">Cargo</th>
<th colspan="12" scope="col">Escenario de Registro</th>
</tr>
<tr>
<td colspan="2">Folio</td>
<td colspan="2">Propietario</td>
<td >Grupo</td>
<td >Edad</td>
<td colspan="2">Folio</td>
<td colspan="2">Suplente</td>
<td >Grupo</td>
<td >Edad</td>
</tr>
<tr id="FilaTable">
<th scope="row" col="1" row="1">Cargo</th>
<td col="2" row="1">LISTA</td>
<td col="3" row="1">
<input type="text" id="AspiranteField" name="AspiranteField" placeholder="FOLIO" />
</td>
<td col="4" row="1">FOTO</td>
<td col="5" row="1">NOMBRE</td>
<td col="6" row="1">GRUPO</td>
<td col="7" row="1">EDAD</td>
<td col="8" row="1">LISTA</td>
<td col="9" row="1">
<input type="text" id="AspiranteField" name="AspiranteField" placeholder="FOLIO" />
</td>
<td col="10" row="1">FOTO</td>
<td col="11" row="1">NOMBRE</td>
<td col="12" row="1">GRUPO</td>
<td col="13" row="1">EDAD</td>
</tr>
</tbody>
And my function is as follows:
$.fn.pressEnter = function(fn) {
return this.each(function() {
$(this).bind('enterPress', fn);
$(this).keyup(function(e){
if(e.keyCode == 13)
{
$(this).trigger("enterPress");
}
})
});
};
$('input').pressEnter(function(){
var trid = ($(this).closest('tr').attr('id'));
var opcion = ($(this).closest('td').index());
var valor = $(this).val();
$.getJSON("php/getAspiranteNombre.php?AspiranteId="+valor,function(data){
$.each(data,function(index,item) {
if(opcion < 4)
{
$("#"+trid+" td").eq(3).html('<p>'+item.NAME+'</p>');
$("#"+trid+" td").eq(4).html('<p>'+item.GRUPO+'</p>');
$.getJSON("php/getFoto.php?AspiranteId="+valor,function(data2){
$("#"+trid+" td").eq(2).html('<img src="aspiranteFoto/thumb_'+data2+'" width="50px" height="50px"/>');
});
$.getJSON("php/getEdad.php?Nacimiento="+item.EDAD,function(data3){
$("#"+trid+" td").eq(5).html('<p>'+data3+'</p>');
});
}
else
{
$("#"+trid+" td").eq(9).html('<p>'+item.NAME+'</p>');
$("#"+trid+" td").eq(10).html('<p>'+item.GRUPO+'</p>');
$.getJSON("php/getFoto.php?AspiranteId="+valor,function(data2){
$("#"+trid+" td").eq(8).html('<img src="aspiranteFoto/thumb_'+data2+'" width="50px" height="50px"/>');
});
$.getJSON("php/getEdad.php?Nacimiento="+item.EDAD,function(data3){
$("#"+trid+" td").eq(11).html('<p>'+data3+'</p>');
});
}
});
});
})
Which basically asks for a value in a database and places it in the spaces. The problem is that, in the first row of the table (dynamically generated) the function works perfectly, but in the subsequent rows it doesn't do anything.
Thanks in advance for your help!

Answer 1

You have to change the way to this one:
$("#PlantillaTable").find("input").keyup(function(ev) {
if (ev.which === 13 ) {
//yout code here...
}
});
Attaches to all input values inside this table the enter button handler.

Answer 2

You first have to loop through each tr separately, then you can target the td's inside.
You can loop through the rows using $.each() like this:
$("table tr").each(function(i,v){
$(this).find("td:eq(3)").html('<p>'+item.NAME+'</p>');
....
});
and it will go through all your rows, not just the first one.
