Trigger onClick event when Enter keypress in a Twitter Bootstrap Modal
提问by ReynierPM
I've a few modals build on top of Twitter Bootstrap Modal, each have at least onesubmit button which is the default action I need to trigger in most cases since the second button is for go back (dismiss the modal), how, on a modal, when I hit enter I can trigger whatever action that submit has? For example right now, as they are button I have something like:
我有一些建立在 Twitter Bootstrap Modal 之上的模态，每个都有至少一个提交按钮，这是我在大多数情况下需要触发的默认操作，因为第二个按钮用于返回（关闭模态），如何，在一个模态，当我按下回车键时，我可以触发提交的任何操作？例如现在，因为它们是按钮，所以我有类似的东西：
$("#btn").on("click", function(e){
e.preventDefault(); // wait... not send form yet, will be a Ajax call
});
Any help? Example code?
有什么帮助吗？示例代码？
For reference, this is the modal content (I using with Twig as part of a Symfony2 project so don't worry about {{ }}):
作为参考，这是模态内容（我使用 Twig 作为 Symfony2 项目的一部分，所以不用担心{{ }}）：
<div class="modal fade " id="addNorma" tabindex="-1" role="dialog" aria-labelledby="addNorma" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">{{ 'boton.cerrar'|trans({}, 'AppBundle') }}</span></button>
<h4 class="modal-title" id="myModalLabel">{{ 'modal.normas.titulo'|trans({}, 'AppBundle') }}</h4>
</div>
<div class="modal-body">
<form id="buscadorNorma" method="POST">
<div class="spacer10"></div>
<div class="row">
<div class="col-md-5 col-lg-5 col-sm-5 col-xs-5">
<label for="codigo_norma">{{ 'modal.normas.codigo'|trans({}, 'AppBundle') }}</label>
<input type="text" class="form-control" id="codigo_norma" name="codigo_norma" placeholder="{{ 'modal.normas.codigoPlaceholder'|trans({}, 'AppBundle') }}">
</div>
<div class="col-md-5 col-lg-5 col-sm-5 col-xs-5 col-md-offset-2">
<label for="ano_publicacion">{{ 'modal.normas.anno'|trans({}, 'AppBundle') }}</label>
<input type="text" class="form-control" id="ano_publicacion" name="ano_publicacion" placeholder="{{ 'modal.normas.annoPlaceholder'|trans({}, 'AppBundle') }}">

</div>
</div>
<div class="spacer10"></div>
<div class="row">
<div class="col-md-12">
<label for="procedencia_producto">{{ 'modal.normas.comite'|trans({}, 'AppBundle') }}</label>
<div class="form-group">
<div>
<select name="comite_tecnico" id="comite_tecnico" class="form-control toSelect2">
<option value="" selected="selected">{{ 'seleccioneOpcion'|trans({}, 'AppBundle') }}</option>
{% for key, item in comiteTecnico %}
<option value="{{ key }}">{{ item.nombre }}</option>
{% endfor %}
</select>
</div>
</div>
</div>
</div>
<div class="spacer5"></div>
<div class="row">
<div class="col-md-12">
<button type="button" class="btn btn-default pull-right" disabled="disabled" id="btnBuscarNorma"><i class="fa fa-binoculars"></i> {{ 'boton.buscar'|trans({}, 'AppBundle') }}</button>
</div>
</div>
</form>
<div class="spacer10"></div>
<table class="table table-hover table-condensed" id="resultadoNorma" style="display: none">
<thead>
<tr>
<th><input type="checkbox" id="toggleCheckboxNorma" name="toggleCheckboxNorma" /></th>
<th>{{ 'columnas.normas.no'|trans({}, 'AppBundle') }}</th>
<th>{{ 'columnas.normas.norma'|trans({}, 'AppBundle') }}</th>
<th>{{ 'columnas.normas.anno'|trans({}, 'AppBundle') }}</th>
<th>{{ 'columnas.normas.comite'|trans({}, 'AppBundle') }}</th>
</tr>
</thead>
<tbody id="resultadoNormaBody"></tbody>
</table>
<div class="alert alert-danger" role="alert" style="display: none;" id="sinResultadosBuscarNormas">
{{ 'mensajes.msgNoEncontrado'|trans({}, 'AppBundle') }}
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">{{ 'boton.regresar'|trans({}, 'AppBundle') }}</button>
<button type="submit" class="btn btn-primary" id="btnAplicarNorma" disabled="disabled"><i class="fa fa-save"></i> {{ 'boton.aplicar'|trans({}, 'AppBundle') }}</button>
</div>
</div>
</div>
</div>
And that's the code I trigger when I click on #btnBuscarNorma:
这就是我点击时触发的代码#btnBuscarNorma：
$('button#btnBuscarNorma').on('click', function (ev) {
ev.preventDefault();
$.post(Routing.generate('filtrarNormas'), $('#buscadorNorma').serialize(), 'json')
.done(function (data, textStatus, jqXHR) {
$('#resultadoNorma').toggle(!!data.entities.length);
$("#sinResultadosBuscarNormas").toggle(!data.entities.length);
if (data.entities.length > 0) {
var $html = '';
data.entities.forEach(function (value, index, array) {
$html += '<tr>';
$html += '<td><input type="checkbox" id="' + value.id + '" value="' + value.id + '"></td>';
$html += '<td>' + value.codigo + '</td>';
$html += '<td>' + value.norma + '</td>';
$html += '<td>' + value.anno + '</td>';
$html += '<td>' + value.comiteTecnico + '</td>';
$html += '</tr>';
});
$("table tbody#resultadoNormaBody").html($html);
marcarTodosCheck('#toggleCheckboxNorma', '#resultadoNormaBody');
}
});
});
The idea is Enterkey will trigger #btnBuscarNormaclick event and not #btnAplicarNormaclick event.
这个想法是Enter关键将触发#btnBuscarNorma点击事件而不是#btnAplicarNorma点击事件。

Bind this event when you open a modal.
打开模态时绑定此事件。
//to prevent multiple binding
$(document).unbind("keyup").keyup(function(e){
var code = e.which; // recommended to use e.which, it's normalized across browsers
if(code==13)
{
$("#btn").click();
}
});

When modal is opened inclass is active on it. So you can get in JQuery:
当模态在课堂上打开时处于活动状态。所以你可以进入JQuery：
$("#addNorma.in").on("keydown",function(e){
if(e.which == 13){
//Do something.
}
});

You can listen for a form submit and prevent it.
您可以监听表单提交并阻止它。
$('#myform').on('submit', function (e) {
e.preventDefault();
});
This way you can make sure the form is never submitted. You can also start the Ajax call when the submit function is called.
通过这种方式，您可以确保永远不会提交表单。您还可以在调用提交函数时启动 Ajax 调用。
A normal button <button>also doesn't submit the form.
普通按钮<button>也不会提交表单。
