I am writing a game for Facebook. IN the following code, I have a problem. I have a for
loop executing, and in that
loop, I call a dialog and implement 'onconfirm' for the dialog. The problem is that I need to access th e
loop counter inside of the onconfirm function. But because the onconfirm is called outside of the scope of the for
loop, the
counter value is no longer valid because it's been incremented. I need some way to pass the
counter value to the dialog onconfirm as it was at the time the dialog was displayed, not after the
loop has finished. Or maybe someone has a better solution. Any help would be appreciated. Thanks.
function unloadCargo() {
//debugger;
var actionPrompt = document.getElementById('action-prompt');
actionPrompt.setTextValue('Unloading cargo...');
var ajax = new Ajax();
ajax.responseType = Ajax.JSON;
ajax.ondone = function(data) {
debugger;
if(data.unloadableCargo.length == 0) {
loadCargo();
} else {
//console.log('unloadable cargo='+dump(data.unloadableCargo));
var i = 0;
var j = 0;
var ucCount = data.unloadableCargo.length;
for(i = 0; i < ucCount; i++) {
cargoDialog = new Dialog();
cargoDialog.showChoice('Unload Cargo', 'Unload ' + data.unloadableCargo[i].goods_name + ' at ' + data.unloadableCargo[i].city_name + ' for ' + data.unloadableCargo[i].payoff + 'M euros?');
cargoDialog.onconfirm = function() {
//console.log('unloadable cargo onconfirm='+dump(data.unloadableCargo));
var ajax = new Ajax();
var param = {"city_id": data.unloadableCargo[i].city_id, "goods_id": data.unloadableCargo[i].goods_id, "payoff": data.unloadableCargo[i].payoff};
ajax.ondone = function(demandData) {
var demands = document.getElementById('demands');
var innerXhtml = '<span>';

innerXhtml = innerXhtml + ' <div class="demand-item"><div class="demand-city">' + demandData.demands[j].city + '</div><div class="demand-pay">' + demandData.demands[j].cost + '</div><div class="demand-goods">' + demandData.demands[j].goods + '</div></div>';
}
innerXtml = innerXhtml + ' </span>';
demands.setInnerXHTML(innerXhtml);
// update balance
