I am dynamically loading stylesheets using YUI3 'Get'. which is working flawlessly however, as far as I can tell it doesn't give me any way to set id's for these new stylesheets which is causing the stylesheet to be loaded multiple times as the user navigates around the site.
var css_obj = Y.Get.css(location.pathname+"/../css/"+jta["iss"]+".css");
Does anyone have any other way of doing this so that I can test prior to loading the css, if it has already been loaded?
Thanks
Did you try using your own variable to check if it's already been loaded?
var css_obj;
function LoadCss() {
if (css_obj == null) {
css_obj = Y.Get.css(location.pathname+"/../css/"+jta["iss"]+".css");
}
}
and if you're using jQuery you could write
$(document).ready(function(){ LoadCss(); });
I like Hunter's solution. You do have access to the inserted link node, though, and you can set its id if you wish:
http://ericmiraglia.com/yui/demos/cssid.php
YUI().use("get", function(Y) {
Y.Get.css("http://ericmiraglia.com/yui/demos/red.css", {
onSuccess: function(o) {
o.nodes[0].setAttribute("id", "myElementId");
alert(o.nodes[0].getAttribute("id"));
}
});
});

The default Accounts-UI widget takes a while to load. I want to check on the client when it is ready, so that I can perform some DOM manipulations on it afterwards. I am currently using a timer like so:
Template.sign_in_modal.onRendered(function (){
Tracker.afterFlush(function () {
Meteor.setTimeout(function () {
$('a#login-sign-in-link').click();
$('a#login-name-link').click();
$('a.login-close-text').remove();
}, 100);
});
});
The above hack works locally (probably because it loads faster) but not when I push to saturnapi.com. I just want it to be expanded by default as shown below. Is there a way to ensure the UI widget is fully loaded via a template helper or otherwise make it expanded by default?
I would suggest checking when the <a id="login-sigin-in-link"></a> is added to the DOM. This could be verified by checking $('a#login-sign-in-link').length. If the element is on the DOM do your manipulation.
However if it is not just check again in a few milliseconds. I would suggest using setInterval().
See below for the complete solution:
Template.sign_in_modal.onRendered(function (){
var setIntervalId = Meteor.setInterval(function() {
if($('a#login-sign-in-link').length) {
$('a#login-sign-in-link').click();
$('a.login-close-text').remove();
Meteor.clearInterval(setIntervalId);
}
}, 100);
});
Template.sign_in_modal.onDestroyed(function() {
$('.modal-backdrop.fade.in').remove();
});
Some may think that using loginButtons.onRendered(function(){}); is a good way to verify if the element has been added to the DOM, but it is not. If you try to do the same DOM manipulation in onRendered, it will throw an afterFlush error. The onRendered function has been extremely misleading.
I'm aware of Template.onRendered, however I have the need to destroy and setup some plugins that act on the dom when the actual context is updated.
So saying I have content template, I'd need something similar to the following:
Template.content.onBeforeChange(function () {
$(".editor").editable("destroy");
});
Template.content.onAfterChange(function () {
$(".editor").editable();
});
Is there any current way I can achieve this with the existing Template api?
You should be able to detect a context change within a template autorun by looking at currentData like this:
Template.content.onRendered(function() {
this.autorun(function() {
if (Template.currentData()) {
// the context just changed - insert code here
}
});
});
I'm unclear if that works for your particular case because this technique only gets you the equivalent of onAfterChange.
anyone using framework7 to create mobile website? I found it was great and tried to learn it by myself, now I meet this problem, after I create my App, I want to do something on the starter page initialization, here, my starter page is index.html, and I set data-page="index", now I write this below:
$$(document).on('pageInit', function (e) {
var page = e.detail.page;
// in my browser console, no "index page" logged
if (page.name === 'index') {
console.log("index page");
});
// but I changed to any other page other than index, it works
// my browser logged "another page"
if(page.name === 'login') {
console.log('another page');
}
});
Anyone can help? Thank you so much.
I have also encountered with the same problem before.
PageInit event doesn't work for initial page, only for pages that you navigate to, it will only work for index page if you navigate to some other page and then go back to index page.
So I see two options here:
Just not use pageInit event for index page - make its initialization just once (just make sure you put this javascript after all its html is ready, or e.g. use jquery's on document ready event)
Leave index page empty initially and load it dynamically via Framework7's mainView.loadContent method, then pageInit event would work for it (that was a good option for me as I had different index page each time, and I already loaded all other pages dynamically from underscore templates)
I am facing same issue and tried all solutions in various forums.. nothing actually worked. But after lot of RnD i stumbled upon following solution ...
var $$ = Dom7;
$$(document).on('page:init', function (e) {
if(e.detail.page.name === "index"){
//do whatever.. remember "page" is now e.detail.page..
$$(e.detail.page.container).find('#latest').html("my html here..");
}
});
var me = new Framework7({material: true});
var mainview = me.addView('.view-main', {});
.... and whatever else JS here..
this works perfectly..
surprisingly you can use "me" before initializing it..
for using for first page u better use document ready event. and for reloading page event you better use Reinit event.
if jquery has used.
$(document).on('ready', function (e) {
// ... mainView.activePage.name = "index"
});
$(document).on('pageReinit', function (e) {
//... this event occur on reloading anypage.
});
I am currently using iron-router and this is my very first attempt to try out the Meteor platform. I has been running into issues where most of the jquery libraries failed to initialized properly because the of the way Meteor renders html, $(document).ready() fires before any templates are rendered. I am wondering is there any callbacks from Meteor/iron-router that allows me to replace the jQuery's dom ready?
Also, how should I (easily and properly) handle the live update of the dom elements if some of them are customized by jQuery/javascript?
This is what i am currently doing, i feel like it is very hackish and probably would run into issues if the elements got updated after the initialization.
var jsInitalized = false;
Router.map(function () {
this.route('', {
path: '/',
layoutTemplate: 'default',
after: function(){
if(!jsInitalized){
setTimeout(function(){
$(document).ready( function() { $$$(); });
}, 0);
jsInitalized = true;
}
}
});
}
With Meteor you generally want to think about when a template is ready, not when the dom is ready.
For example, let's say you want to use the jQuery DataTables plugin to add sorting to a table element that's created by a template. You would listen to the template's rendered event and bind the plugin to the dom:
HTML:
<template name="data_table">
<table class="table table-striped" id="tblData">
</table>
</template>
JavaScript:
Template.data_table.rendered = function () {
$('#tblData').dataTable();
};
Now anytime the template is re-rendered (for example, if the data changes), your handler will be called and you can bind the jQuery plugin to the dom again.
This is the general approach. For a complete example (that includes populating the table with rows) see this answer.
Try making a separate .js file, call it rendered.js if you'd like. and then;
Template.layout.rendered = function ()
{
$(document).ready(function(){console.log('ready')});
}
I use template layout, but you can do Template.default.rendered. I hope that helps.
Also take a look at this part of documentation, especially the Template.events; http://docs.meteor.com/#templates_api
I use Meteor v0.8.0 with Iron Router (under Windows 7) and here is how I handle 'DOM ready':
When I want to modify the DOM after a specific template has been rendered:
I use Template.myTemplateName.rendered on the client side :
Template.blog.rendered = function()
{
$('#addPost').click(function()
{
...
});
}
When I want to modify the DOM after any new path has been rendered:
I use Router.onAfterAction, but there seems to be a trick:
Router.onAfterAction(function()
{
setTimeout(function()
{
$('.clickable').click(function()
{
...
});
}, 0);
});
Notice the setTimeout(..., 0), it doesn't work for me otherwise (DOM empty).
Notice that you can use onAfterAction on specific path, but most of the time I think it is redundant with the Template.myTemplateName.rendered method above.
What seems to be missing:
A way to modify the DOM after any template has been rendered.
I was hoping anyone could give some input on this,
I'm creating a meteor app in which I would like to use bootstrap to creating the admin environment, but have the visitor facing side using custom css. When I add the bootstrap package to my app using meteor it's available on every page, is there a way to restrict the loading of bootstrap to routes that are in '/admin' ?
When you add bootstrap package it's not possible. You can, however, add bootstrap csses to public directory and then load them in a header subtemplate that will only be rendered when you're in the dashboard.
EDIT
But then how would you go about creating seperate head templates?
Easy:
<head>
...
{{> adminHeader}}
...
</head>
<template name="adminHeader">
{{#if adminPage}}
... // Put links to bootstrap here
{{/if}}
</template>
Template.adminHeader.adminPage = function() {
return Session.get('adminPage');
}
Meteor.router.add({
'/admin': function() {
Session.set('adminPage', true);
...
}
});
DISCLAIMER: I am unsure of a 'meteor way' to do this, so here is how I would do it with plain JS.
jQuery
$("link[href='bootstrap.css']").remove();
JS - Credit to javascriptkit
function removejscssfile(filename, filetype){
var targetelement=(filetype=="js")? "script" : (filetype=="css")? "link" : "none" //determine element type to create nodelist from
var targetattr=(filetype=="js")? "src" : (filetype=="css")? "href" : "none" //determine corresponding attribute to test for
var allsuspects=document.getElementsByTagName(targetelement)
for (var i=allsuspects.length; i>=0; i--){ //search backwards within nodelist for matching elements to remove
if (allsuspects[i] && allsuspects[i].getAttribute(targetattr)!=null && allsuspects[i].getAttribute(targetattr).indexOf(filename)!=-1)
allsuspects[i].parentNode.removeChild(allsuspects[i]) //remove element by calling parentNode.removeChild()
}
}
removejscssfile("bootstrap.css", "css")
However, doing that would complete remove it from the page. I am not sure whether meteor would then try to readd it when a user goes to another page. If that does not automatically get readded, then you have an issue of bootstrap not being included when someone goes from the admin section to the main site, which would break the look of the site.
The way I would get around that would be to disable and enable the stylesheets:
Meteor.autorun(function(){
if(Session.get('nobootstrap')){
$("link[href='bootstrap.css']").disabled = true;
}else{
$("link[href='bootstrap.css']").disabled = false;
}
});
There my be other bootstrap resources which may need to be removed, take a look at what your page is loading.
To use jQuery in the same way but for the javascript files, remember to change link to script and href to src
From my tests, Meteor does not automatically re-add the files once they have been removed so you would need to find some way of re-adding them dynamically if you want the same user to be able to go back and forth between the main site and the admin site. Or simply if the http referrer to the main site is from the admin, force reload the page and then the bootstrap resources will load and everything will look pretty.
P.s. make sure you get the href correct for the jQuery version
If somebody is interested in including any js/css files, I've written a helper for it:
if (Meteor.isClient) {
// dynamic js / css include helper from public folder
Handlebars.registerHelper("INCLUDE_FILES", function(files) {
if (files != undefined) {
var array = files.split(',');
array.forEach(function(entity){
var regex = /(?:\.([^.]+))?$/;
var extension = regex.exec(entity)[1];
if(extension == "js"){
$('head').append('<script src="' + entity + '" data-dynamicJsCss type="text/javascript" ></script>');
} else if (extension == "css"){
$('head').append('<link href="' + entity + '" data-dynamicJsCss type="text/css" rel="stylesheet" />');
};
});
}
});
Router.onStop(function(){
$("[data-dynamicJsCss]").remove();
});
}
Then simply use:
{{INCLUDE_FILES '/css/html5reset.css, /js/test.js'}}
in any of your loaded templates :)
