I need to get current url from Ember as a "redirectTo" parameter. The parameter will be used to redirect users back to the same page after they login from other app. The url looks like
http://test.com/apps/#/tables/7
I've found this post to get currentPath/route from the application. It provides the current route name but I wonder how I can get the complete path including id from Ember. I have a nested route declaration looks like below.
App.Router.map(function() {
this.resource('tables', function() {
this.resource('table', { path: ':table_id' });
});
});
Any suggestion is welcome. Thanks!
Observe the currentPath in ApplicationController and update the current URL:
App.ApplicationController = Ember.Controller.extend({
currentPathDidChange: function() {
App.currentUrl = window.location.href;
}.observes('currentPath')
});
Can you just use window.location?
var url = window.location.href;
Thanks #Panagiotis Panagi, it works.
Furthermore, currentUrl can only be accessed from application controller, so if you want to get it from other place, you can add this code to a certain controller you want to access it :
export default Ember.Controller.extend({
needs: ['application'],
currentPath: Ember.computed.alias('controllers.application.currentPath'),
...
}

Is this possible to always redirect
from
www.name.blogspot.com/title
to
www.name.blogspot.com/p/title.html
For example, when someone type www.name.blogspot.com/title
so it is automatically redirect to www.name.blogspot.com/p/title.html
maybe need some javascript that always auto-generate to convert incoming url to the correct url.
usually, I used this script below, but it still manually method, so edited one by one if there is many links.
<script>
if(window.location.href == 'https://www.name.blosgpot.com/title')
{
window.location="https://www.name.blosgpot.com/p/title.html";
}
</script>
Thankyou for your help
Idealy you want to do this in the server, for example, if you are using Nginx, you can rewrite incomming requests with a given pattern URL to another path:
server{
...
location /title {
rewrite ^/(.*)$ https://www.newsite.com/p/$1 redirect;
}
...
}
But if you need to do it on the client, you can use a similar logic, matching patterns and "rewriting" the URL, something like this:
const myPattern = /https:\/\/name.blosgpot.com(.*)/
const path = window.location.href.match(myPattern)[1]
if (path) {
window.location.href = "https://www.name.blosgpot.com/p" + path
}
Am playing with Framework7 to do hybrid mobile app development. I have three tabs (bottom fixed), which are Home, Contacts and Settings/Profile
My app.js file looks somewhat like this:
var $$ = Dom7;
var app = new Framework7({
//.....
data: function () {
return {
user_profile : ''
}
},
on: {
tabShow( tab ) //-- when a bottom tab is clicked
{
if( $$(tab).attr('id') == 'view-settings' )
{
//.. do ajax call and get the response data in "resp"
app.data.user_profile = resp.response.profile; //setting the info to app's data
}
}
},
routes: routes
});
var settingsView = app.views.create('#view-settings', {
url: '/settings/'
});
And in routes.js:
routes = [
{
path: '/',
url: './index.html',
},
{
path: '/contacts/',
componentUrl: './pages/contacts.html',
},
{
path: '/settings/',
componentUrl: './pages/settings.html',
}
];
This Contacts page contains static content. For the Home page, am doing the AJAX API call during the deviceready state. Because am setting up some headers for authentication and stuff(for all the AJAX api calls) in there.
The problem am facing is, am unable to display the content in Settings page. It is always empty!
Am using this in that template page:
<div class="item-title item-label">Full Name - {{$root.user_profile.full_name}}</div>
I want to compile that template only when clicking the respective tab button.
Maybe that's the problem.
Any suggestions?
After going through the documentations again and again, I got another way to do this.
So, during the tabShow event, I check whether the user is accessing the Settings/Profile tab. If so, I check whether an object in app.data (eg: app.data.user_profile is empty or not(am storing the profile details there). If empty, I would do an AJAX API call to get the profile details. When the profile details is obtained, I would use app.form.fillFromData() method to fill the form. Documentation here: https://framework7.io/docs/form.html#form-data-app-methods
Make sure to name the form as well as the input elements in that form, and the same name should be use in the object(key name) when calling the fillFromData() function.
And one more thing, for the routes, /settings/ path, I used url instead of the componentUrl property to pass the url of the page.
This may not be the best solution, but am still learning. And it seems to have solved by current problem.
Thank you
I have created a backbone project, all the html's are now converted into jsp pages.
I am able to load the page if I am using the corresponding page jsp name in the URL.
For Example
localhost:8080/abc/index.jsp || localhost:8080/abc/landing.jsp
But the problem am facing is if I have a internal page routing, for example like
Consider a login page, which has forgot password link, if i click on that it should redirect to the forgot password page which is not happening.
For navigation am using window.location.pathname = "/abc/landing.jsp"
Manually am doing like this, is there a proper way to achieve with jsp pages navigation. Please help.
Code:
forgotpassword.jsp:
<input type="hidden" value="forgotPassword">
<div id="fp"></div>
based on the input hidden parameter, am deciding which new needs to be rendered.
and the formation of url is http://localhost.abc.com:8080/test/forgotpassword.jsp
Here is my router logic:
define(['jquery', 'underscore', 'backbone'], function($, _, Backbone) {
var AppRouter = Backbone.Router.extend({
routes: {
'*': 'default'
},
});
var initialize = function() {
var apRouter = new AppRouter;
apRouter.on('route:default', function() {
if ($('input').val == "fp") {
require(['forgotpasswordView'], function(ForgotPswrd) {
var fpwrd = new ForgotPswrd();
fpwrd.render();
});
else {
require(['indexView'], function(IndexView) {
var iView = new IndexView();
iView.render();
});
}
}
});
Backbone.history.start();
};
return {
initialize: initialize
};
});
So If i manually hit the URL appending corresponding jsp names like
http://localhost.abc.com:8080/test/forgotpassword.jsp or
http://localhost.abc.com:8080/test/index.jsp
Then pages are loading and working fine. But If am calling another view from one view to another view then it is failing.
Like landing.html:
<button id="goTo"> Go to Next View </button>
Landing View JS:
events : "click#goTo : goTo"
goTo : function(evt){
evt.preventDefault();
Backbone.history.navigate('/',true);
}
Now the forgot password page needs to load but the url is not changing just appending hash to the previous url what ever is there.
Kindly help.
Backbone relies on router to make navigation possible.So if you have a route defined in the backbone route you can navigate to it by calling the route directly using the backbone route object.In your case you can create a route for the password forgotten link and load the template or view in the function def for that route .Trigger the ROUTE 'ON CLICK'.Eg :
var AppRouter = Backbone.Router.extend({
routes: {
'*': 'default',
'/forgotpassword' : 'forgotPass'
},
});
var appRoute = new AppRouter;
forgotPass() {
// load the view here
}
$('#button').on('click',function() {
appRoute.navigate('/forgotpassword',true);
});
Please note that you cannot load a jsp page as such through backbone js as the jsp files needs to be transpiled before rendering html which cannot be done at client side. So you option is to use a templating engine like handlebar js and render the view using handlebar templates wherever necessary.
I have an ember action that submits a form using jquery post like this,
submit : function(){ //submitting new story
this.set('onsubmit' , true);
var self = this;
$.post( "/api/post", { some post data })
.done(function(data) {
self.transitionTo('post' + data);
});
}
The urls are like this, domain example.com. Post is located at example.com/api/post. After posting the user must be redirected to example.com/post/3432232 (some value returned by the post data).
However after posting this transition to "example.com/api/post/5000203" not example.com/post/234234234.
Which doesnt exists and gives a 404. How can I make the user go back to example.com/post/234234234 using transition-to function in ember?
Edit - Routes are as follows
App.Router.map(function() {
this.resource('index', {path : '/'} , function() {
this.resource('p', function(){
this.resource('post', { path: ':post_id' });
});
});
});
Thanks
In Ember routing system transitionTo takes as arguments route's name and route's model (the same model, that route returns when Ember.Route.model hook is invoked). There are two type of router's transitions in Ember's glossary: URL transition (happens when client handles new URL, fo ex., when you open a page from scratch) and "named transition" (which happens when this.tranisionTo is called).
Ember.Route tries to load model based on params list (:post_id, for example) while handling "URL transition". In other hand, while it handling "named transition" it doesn't call model hook, but uses already provided model (this.tranisition('post', PostModel)`). Docs.
So, if you have post_id on hands, just call this.store.find('post', postId) to get PostModel and provide requested model to PostRoute: this.transitionTo('post', this.store.find('post', data).
P.S. Please, consider reading this question and an answer to get your routing structure actually nested: Nested URLs: issues with route transition.
P.P.S. I looked at the Ember's documentation and found new (at least for me) signatures for transitionTo method: http://emberjs.com/api/classes/Ember.Route.html#method_transitionTo. According to this doc, you can rewrite your example to get it work: this.tranisitionTo('post', data), where data is post_id.
I am trying to implement a search function for my website. When the user types a search term foobar into a input box and submits it, he is redirected to http://mydomain.com/search?query=foobar.
Problem:: How should I grab the GET parameters query from the URL, and send it to the backend and get a array of results back as a JSON response? Should I even do it this way?
My current attempt below does not even cause the search function to be triggered.
Router
var AppRouter = Backbone.Router.extend({
routes: {
'search?query=:query': 'search'
// ... and some other routes
},
search: function(query) {
this.photoList = new SearchCollection();
var self = this;
this.photoList.fetch({
data: {query: query},
success: function() {
self.photoListView = new PhotoListView({ collection: self.photoList });
self.photoListView.render();
}
});
}
});
var app = new AppRouter();
Backbone.history.start({
pushState: true,
root: '/'
});
There have been several issues filed against Backbone for this very issue. There is an existing plugin that works well for this:
https://github.com/jhudson8/backbone-query-parameters
Alternatively, I'm currently using query string parameters in a mock API that matches Backbone's route matching. Looks something like this
Route
"/api/v2/application/:query"
Query
application: function(query) {
var params = $.deparam(query.slice(1));
// params.something...
}
As to your actual issue at hand how are you redirecting to index.html to support pushState?
I hit this same issue and contemplated using backbone-query-parameters, but that should be considered generally an incorrect approach.
The url query string is not meant for the front end. They get sent to the server and force a refresh when navigating from page.html to page.html?something=something.
You should be using hash fragments instead. i.e. http://www.example.com/ajax.html#key1=value1&key2=value2 then just get those values the normal backbone way and build your request params from that.
See https://github.com/jashkenas/backbone/issues/891, https://developers.google.com/webmasters/ajax-crawling/docs/specification, https://www.rfc-editor.org/rfc/rfc3986#section-3.5
You can always read the URL via jQuery URL plugin. It works well.
https://github.com/allmarkedup/jQuery-URL-Parser
There are very few cases when you need to read the URL and extract the GET params. I think that you are doing things wrong and here are my options:
1) if you are having just one page in your app (single app page) you can display results as they type in your input field or after they hit submit
2) if you are redirecting the user to a different page that means you can bootstrap data so that after the page is loaded backbone will just have to render your results and only make other requests if you change your search word
3) you can have a javascript variable which is initialized on page load directly from the server where working with GET params is probably easier
