PHP / FBJS bir Facebook uygulaması yazıyorum. Ben iki düğme () bir addEventListener eklemek bazı kodlar var. Ben uygulaması çalıştırdığınızda, ben yangınlar addEventListener () ilk düğmesini tıklayın ve beklendiği gibi olay işleyicisi çağrılır. Ben ikinci butonuna tıklayın ya da tekrar aynı düğme üzerine tıklayın Ama eğer olay işleyicisi çağrılır. İşte benim kod:
//PHP
public function loadCargoDialogFbjsAction() {
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender();
$loadableCargo = $this->getRequest()->getPost('loadableCargo');
$fbjs =
'<div id="load_cargo_select">
<form id="load_cargo_select_form" action="" method="POST">
<p>Your train has stopped in the city of ' . $loadableCargo['city'] . '</p>
<p>' . $loadableCargo['city'] . ' produces the following goods:</p>
<ul>';
if(count($loadableCargo['city_goods']) <= 0) {
$fbjs .= '<li>None</li>';
} else {
foreach($loadableCargo['city_goods'] as $goods) {
$fbjs .= '<li>' . $goods['name'] . '</li>';
}
}
$fbjs .=
'</ul>
<p>Your train is hauling the following goods:</p>
<ul>';
if(count($loadableCargo['train_goods']) <= 0) {
$fbjs .= '<li>None</li>';
} else {
foreach($loadableCargo['train_goods'] as $goods) {
$fbjs .= '<li>' . $goods['name'] . '</li>';
}
}
$fbjs .=
'</ul>
<p>What would you like to do?</p>

Bu unsurların tekrarını önlemek için aşağıdaki gibi benim loadCargo () işlevi değişti, ama ben yine de daha önce aynı sorun haline çalıştırıyorum.
var loadCargoDialog;
function loadCargo() {
var actionPrompt = document.getElementById('action-prompt');
actionPrompt.setTextValue('Loading cargo...');
var ajax = new Ajax();
ajax.responseType = Ajax.JSON;
ajax.ondone = function(data) {
//debugger;
ajax.responseType = Ajax.FBML;
ajax.ondone = function(fbjsData) {
//debugger;
if(data.loadableCargo.length == 0) {
moveTrainManual();
} else {
if(loadCargoDialog == null) {
loadCargoDialog = new Dialog().showChoice('Load Cargo', fbjsData, 'Minimize', 'Pass');
var dlgBtnNew = document.getElementById('load-new-submit');
dlgBtnNew.cityId = data.loadableCargo.city_id;
dlgBtnNew.trainId = data.loadableCargo.train_id;
dlgBtnNew.addEventListener('click', cargoEventHandler, true); //loadNewCargo);
var dlgBtnDiscard = document.getElementById('discard-existing-submit');
dlgBtnDiscard.cityId = data.loadableCargo.city_id;
dlgBtnDiscard.trainId = data.loadableCargo.train_id;
dlgBtnDiscard.addEventListener('click', discardExistingCargo, true);
} else {
loadCargoDialog.showChoice('Load Cargo', fbjsData, 'Minimize', 'Pass');
}
loadCargoDialog.onconfirm = function() {
// Submit the form if it exists, then hide the dialog.
loadCargoDialog.hide();
actionPrompt = document.getElementById('action-prompt');
actionPrompt.setInnerXHTML('<span><div id="action-text">'+
'The "Load cargo" dialog has been minimized'+
'</div>'+
'<div id="action-end">'+
'<form action="" method="POST">'+
'<input type="button" value="Maximize" id="next-phase" onclick="loadCargo();" />'+
'</form>'+
'</div></span>');
actionButton = document.getElementById('next-phase');
actionButton.setValue('Maximize');
actionButton.addEventListener('click', loadCargoEventHandler);
};
loadCargoDialog.oncancel = function() {
moveTrainManual();
}
}
}
ajax.post(baseURL + '/turn/load-cargo-dialog-fbjs', data);
}
ajax.post(baseURL + '/turn/load-cargo');
}
