[英]Force Meteor To Refresh / Re-render Templates?
*作為參考,我使用的是鐵路由器。
我將這個全局登錄表單而不是登錄頁面嵌入到導航欄中(也稱為每個頁面)。 現在,我正在進行一次非常hacky的刷新,以在用戶登錄后重新加載頁面。
我只想重新加載到模板,也就是不刷新整個頁面。 基本上只希望模板呈現的功能在登錄時重新運行。
這是我當前的登錄代碼:
'submit #login': function(event, template){
event.preventDefault();
var handle = template.find('#usernameLogin').value;
var secretKey = template.find('#passwordLogin').value;
Meteor.loginWithPassword(handle, secretKey, function(err){
if (err) {
alert(err);
}else{
$('#close').click();
/* replace this with reactive ajax or whatever when you can! */
Meteor._reload.reload();
}
});
},
我認為現在的渲染功能可能是真正的問題:
Template.tournament.rendered = function () {
thisCampaign = this.data;
var self = this;
if (this.data.tournament.live) {
/* if theres a registered user */
if (Meteor.userId()) {
/* Select a winner box */
var participants = $('.participant-id');
var currentParticipant;
var nextRound;
var thisMatch;
var nextMatch;
var bracket;
participants.map(function(index, value){
if ($(value).text() === Meteor.userId()) {
if ($(value).parent().find('.participant-status').text() === 'undetermined') {
nextRound = $(value).parent().find('.participant-round').text();
thisMatch = $(value).parent().find('.participant-match').text();
bracket = $(value).parent().parent().parent().find('.participant');
};
};
});
nextRound = parseInt(nextRound) + 1;
nextMatch = Math.round(parseInt(thisMatch)/2) - 1;
if (parseInt(thisMatch) % 2 != 0) {
currentParticipant = 0;
}else{
currentParticipant = 1;
}
var winnerOptions = '';
var winnerBox = $('<div class="select-winner">');
if (bracket) {
bracket.map(function(index, value) {
winnerOptions += '<span class="winner-option"> '+$(value).find('.participant-title').text()+' <div class="winner-info"> '+$(value).find('a').html()+' </div> </span>'
});
winnerBox.append(winnerOptions);
$($($('.round'+nextRound).find('li')[nextMatch]).find('.participant')[currentParticipant]).removeClass('loser').addClass('undetermined');
$($($('.round'+nextRound).find('li')[nextMatch]).find('.participant')[currentParticipant]).find('a').addClass('tooltip').html(winnerBox);
};
}else{
}
}else{
/* Tournament Start Time */
var tournamentStartTime = function(){
var d = new Date();
var n = d.getTime();
var currentTime = TimeSync.serverTime(n);
var startTime = self.data.card.startTime;
var difference = startTime - currentTime;
var hoursDifference = Math.floor(difference/1000/60/60);
difference -= hoursDifference*1000*60*60
var minutesDifference = Math.floor(difference/1000/60);
difference -= minutesDifference*1000*60
var secondsDifference = Math.floor(difference/1000);
/* if ends (make tournament live server side?) */
if (hoursDifference < 0 || minutesDifference < 0 || secondsDifference < 0) {
Meteor.clearInterval(tStartTime);
Session.set("tournamentStartTime", false);
}else{
if (hoursDifference < 10) {hoursDifference = "0"+hoursDifference;}
if (minutesDifference < 10) {minutesDifference = "0"+minutesDifference;}
if (secondsDifference < 10) {secondsDifference = "0"+secondsDifference;}
var formattedTime = hoursDifference + ':' + minutesDifference + ':' + secondsDifference;
Session.set("tournamentStartTime", formattedTime);
}
};
Session.set("tournamentStartTime", '00:00:00');
tournamentStartTime();
var tStartTime = Meteor.setInterval(tournamentStartTime, 1000);
/* Allow new user sign up */
var alreadySignedUp = false;
var usersSignedUp = $('.participant-id')
usersSignedUp.map(function (index, user) {
if ($(user).text().trim() === Meteor.userId()) {
alreadySignedUp = true;
}
});
if (this.data.card.host != Meteor.user().username && !(alreadySignedUp)) {
var openSlots = [];
var allSlots = $('.participant');
allSlots.map(function (index, participant) {
if ($(participant).find('.participant-title').text().trim() === '' && !($(participant).hasClass('loser'))) {
openSlots.push(participant);
}
});
openSlots.map(function (openSlot, index) {
$(openSlot).removeClass('winner').addClass('undetermined');
});
}
/* if theres a registered user */
if (Meteor.userId()) {
}else{
}
}
};
從我可以看到的地方,您的渲染功能將無法按預期工作,因為在loggingIn
狀態仍在發生時模板可能會渲染...
我的建議是在{{#if currentUser}} page here{{/if}}
使用類似的內容,然后將要嘗試運行的代碼放在currentUser
塊內的幫助器中的呈現器中。僅在有登錄用戶時顯示並被調用,否則它將不會顯示,並且您無需重新渲染頁面即可執行任何操作。
基本上,一旦用戶登錄,具有Meteor.userId()
或Meteor.user()
函數的任何幫助程序(呈現的助手Meteor.user()
都將自動重新運行,否則,您可以在Tracker.autorun
函數中執行登錄操作如果它們是每個客戶對您的應用程序全局的。
