I've been searching for an hour on how to nagivate within my Laravel website without refreshing the website (page layout), but I couldn't find a proper solution: one that not just loads the HTML, but actually replaces the content view within the layout.
This is my current dashboard:
So when clicking on a menu item within the blue area, I want the red content area to change without page refresh. What would be a scalable solution for this? I'm trying to follow the DRY (Don't repeat yourself) principle as much as possible.
Oh, please don't mark this topic as a clone of other topics as I've seen most of them but without proper solution. Hope anyone can help me out.
Changing a view without page load means we need to use the ajax techology. Vuejs is a frontend frameework the allows us to acomplish that easily with its axios library
I believe you can get this done by using jQuery load function -
$(function () {
$("#menu_option_a").on("click", function () {
$("#dashboard").load("View1.html");
});
$("#menu_option_b").on("click", function () {
$("#dashboard").load("View2.html");
});
});

Ok, this idea might seem quite a bit crazy and it kindo' is (at least for me at my level).
I have a fairly standarad rails app (some content pages, a blog, a news block, some authentication). And I want to make it into a single page app.
What I want to accomplish is:
All the pages are fetched through AJAX like when using turbolinks, except that the AJAX returns only the view part (the yield part in the layout) withought the layout itself, which stays the same (less data in the responces, quicker render and load time).
The pages are mostly just static html with AngularJS markup so not much to process.
All the actual data is loaded separately through JSON and populated in the view.
Also the url and the page title get changed accordingly.
I've been thinking about this concept for quite a while and I just can't seem to come up with a solution. At this point I've got to some ideas on how this actualy might be done along with some problems I can't pass. Any ideas or solutions are greatly appreciated. Or might be I've just gone crazy and 3 small requests to load a page are worse then I big that needs all the rendering done on server side.
So, here's my idea and known problems.
When user first visits the app, the view template with angular markup is rendered regularly and the second request comes from the Angular Resource.
Then on ngClick on any link that adress is sent to ngInclude of the content wrapper.
How do I bind that onClick on any link and how can I exclude certain links from that bind (e.g. links to external authentication services)?
How do I tell the server not to render the layout if the request is comming from Angular? I though about adding a parameter to the request, but there might be a better idea.
When ngInclude gets the requested template, it fires the ngInit functions of the controllers (usually a single one) in that template and gets the data from the server as JSON (along with the proper page title).
Angular populates the template with the received data, sets the browser url to the url of the link and sets the page title to what it just got.
How do I change the page title and the page url? The title can be changed using jQuery, but is there a way through Angular itself?
Again, I keep thinking about some kind of animation to make this change more fancy.
Profit!
So. What do you guys think?
OK, in case enyone ever finds this idea worth thinking about.
The key can be solved as follows.
Server-side decision of whether to render the view or not.
Use a param in the ngInclude and set the layout: false in the controller if that param is present.
Have not found an easier way.
Client-side binding all links except those that have a particular class no-ajax
Here's a directive that does it.
App.directive('allClicks', function($parse) {
return {
restrict: 'A',
transclude: true,
replace: true,
link: function(scope, element, attrs) {
var $a = element.find('a').not($('a.no-ajax')),
fn = $parse(attrs['allLinks']);
$a.on('click', function(event) {
event.preventDefault();
scope.$apply(function() {
var $this = angular.element(event.target);
fn(scope, {
$event: event,
$href: $this.attr('href'),
$link: $this
});
});
});
}
};
})
And then use it on some wrapper div or body tag like <body ng-controller="WrapperCtrl" all-links="ajaxLink($href)"> and then in your content div do <div id="content" ng-include="current_page_template">
In your angular controller set the current_page template to the document.URL and implement that ajaxLink function.
$scope.ajaxLink = function(path) {
$scope.current_page_template = path+"?nolayout=true";
}
And then when you get your JSON with your data from the server don't forget to use history.pushState to set the url line and document.title = to setr the title.
I am using the following directive to create a ckEditor view. There are other lines to the directive to save the data but these are not included as saving always works for me.
app.directive('ckEditor', [function () {
return {
require: '?ngModel',
link: function ($scope, elm, attr, ngModel) {
var ck = ck = CKEDITOR.replace(elm[0]);
ngModel.$render = function (value) {
ck.setData(ngModel.$modelValue);
setTimeout(function () {
ck.setData(ngModel.$modelValue);
}, 1000);
}; }
};
}])
The window appears but almost always the first time around it is empty. Then after clicking the [SOURCE] button to show the source and clicking it again the window is populated with data.
I'm very sure that the ck.setData works as I tried a ck.getData and then logged the output to the console. However it seems like ck.setData does not make the data visible at the start.
Is there some way to force the view window contents to appear?
You can call render on the model at any time and it will simply do whatever you've told it to do. In your case, calling ngModel.$render() will grab the $modelValue and pass it to ck.setData(). Angular will automatically call $render whenever it needs to during its digest cycle (i.e. whenever it notices that the model has been updated). However, I have noticed that there are times when Angular doesn't update properly, especially in instances where the $modelValue is set prior to the directive being compiled.
So, you can simply call ngModel.$render() when your modal object is set. The only problem with that is you have to have access to the ngModel object to do that, which you don't have in your controller. My suggestion would be to do the following:
In your controller:
$scope.editRow = function (row, entityType) {
$scope.modal.data = row;
$scope.modal.visible = true;
...
...
// trigger event after $scope.modal is set
$scope.$emit('modalObjectSet', $scope.modal); //passing $scope.modal is optional
}
In your directive:
ngModel.$render = function (value) {
ck.setData(ngModel.$modelValue);
};
scope.$on('modalObjectSet', function(e, modalData){
// force a call to render
ngModel.$render();
});
Its not a particularly clean solution, but it should allow you to call $render whenever you need to. I hope that helps.
UPDATE: (after your update)
I wasn't aware that your controllers were nested. This can get really icky in Angular, but I'll try to provide a few possible solutions (given that I'm not able to see all your code and project layout). Scope events (as noted here) are specific to the nesting of the scope and only emit events to child scopes. Because of that, I would suggest trying one of the three following solutions (listed in order of my personal preference):
1) Reorganize your code to have a cleaner layout (less nesting of controllers) so that your scopes are direct decendants (rather than sibling controllers).
2) I'm going to assume that 1) wasn't possible. Next I would try to use the $scope.$broadcast() function. The specs for that are listed here as well. The difference between $emit and $broadcast is that $emit only sends event to child $scopes, while $broadcast will send events to both parent and child scopes.
3) Forget using $scope events in angular and just use generic javascript events (using a framework such as jQuery or even just roll your own as in the example here)
There's a fairly simple answer to the question. I checked the DOM and found out the data was getting loaded in fact all of the time. However it was not displaying in the Chrome browser. So the problem is more of a display issue with ckEditor. Strange solution seems to be to do a resize of the ckEditor window which then makes the text visible.
This is a strange issue with ckeditor when your ckeditor is hidden by default. Trying to show the editor has a 30% chance of the editor being uneditable and the editor data is cleared. If you are trying to hide/show your editor, use a css trick like position:absolute;left-9999px; to hide the editor and just return it back by css. This way, the ckeditor is not being removed in the DOM but is just positioned elsewhere.
Use this java script code that is very simple and effective.Note editor1 is my textarea id
<script>
$(function () {
CKEDITOR.timestamp= new Date();
CKEDITOR.replace('editor1');
});
</script>
Second way In controller ,when your query is fetch data from database then use th
is code after .success(function().
$http.get(url).success(function(){
CKEDITOR.replace('editor1');
});
I know, that this thread is dead for a year, but I got the same problem and I found another (still ugly) solution to this problem:
instance.setData(html, function(){
instance.setData(html);
});
I have an element in my product list page that I want to hide until the rest of the document has finished loading. (it's a list item with the class "hideme")
The JS solution doesn't work for me, so I'm looking for a scriptaculous method, which should work better in Magento.
Any help would be greatly appreciated.
Thanks!
If you want to make something client-side once the DOM has been loaded, you should try with this:
document.observe("dom:loaded", function() {
// initially hide all containers for tab content
$$('div.tabcontent').invoke('hide');
});
Is more like jQuery(document).ready();
Greetings.
There is a problem when I put Kendo Dropdown List info Fancybox - Popup.
For detail:
I have page A :this page contains Kendo Dropdown list (with id = #myDropdown).
I have page B : I put my Fancybox caller here- I mean I use Fancybox to load page A (by ajax)
Everything look well , but I got a problem here:
You know, when I initialize a Dropdown List, Kendo-UI will create an "anchor" Tag for UI-effect purpose.
Ex:
DropdownList has id = #myDropdown
Kendo will create one more Tag with id = #myDropdown-list.
After closing the Fancybox-popup , The "#myDropdown" was removed from DOM, but "#myDropdown-list". It still on the DOM overtime, and it willing to be double after I call the popup again(ofcourse if dont refresh current page).
And The Kendo-DateTimePicker as the same too.
p/s: and so sorry about by english if it was too bad :D. I hope you get my question.
im going to put my "popup" in iframe.But I dont know if it is good when using iframe in this case...
Using IFrame or not is not the cause of the error. I tried with a container and without it to load the fancybox via ajax, but it didn't make a difference.
What I found is sort of a hack, however it solves the problem. Let's suppose we have a code which creates the popup and the popup's content is located in the href 'popupFrame':
$.fancybox({
'href': 'popupFrame',
'type': 'ajax',
beforeClose: removeKendoHelpers
});
The other part is the function which is called before closing the popup:
function removeKendoHelpers() {
$("#myDropdown-list").remove();
}
Of course you can create the removeKendoHelpers as an inline function and if there are more parts to remove then put that code into the removeKendoHelpers function as well.
One interesting remark: in the fancybox API onCleanup and onClosed are listed as options but they do not work, instead use beforeClose or afterClose.
UPDATE:
Actually a lot of problem is solved with calling the kendo widget's destroy() method. It solves the removing problems for the widgets except for one of the three helper divs of the DateTimePicker, so the close looks like the following:
function removeKendoHelpers() {
$("#myDropdown-list").data("kendoDropDownList").destroy();
$("#datetimepicker").data("kendoDateTimePicker").destroy();
}
And to resolve the date time picker's actual problem which is I think a bug in the kendop framework (I will report this and hopefully get some feedback) the last function only needs to be extended with:
$(".k-widget.k-calendar").remove();
OTHER solution:
This one is more crude but works like a charm for me even if the page has multiple kendo controls and even if you open another fancybox from your fancybox.
Wrap the fancybox creation in a function, like:
function openFancyBox() {
$("body").append("<div class='fancybox-marker'></div>");
$.fancybox({
'href': 'popupFrame',
'type': 'ajax',
beforeClose: removeKendoHelpers
});
}
This will create a new div at the very end of the body tag, and the function at the closing of the fancybox uses this:
function removeKendoHelpers() {
$(".fancybox-marker").last().nextAll().remove();
$(".fancybox-marker").last().remove();
}
I hope these solves all your problem!
I have a partial view that I have included on my _Layout.cshtml. It simply has a javascript function that changes an image based on the state of my system. I don't need to reload any data, I don't need to go to the code of the controller for anything, I simply need to reload that partial view.
I tried many of the examples that I found here but couldn't get any of them to work. I felt as if they were too complex for what I was doing anyway. Any guidance would be appreciated.
Thanks,
Steve
If the partial is loaded into the layout directly then there's no straightforward way to refresh it, because it's basically a part of the complete rendered page.
Your best bet is to render the partial using $.load or whatever equivalent you have available by hitting a controller method and rendering the result into a container (like a div). You would have to do this within a script that is loaded with the layout itself, by observing document.ready or something like that. Once you have that in place then it's trivial to keep reloading or refreshing the contents by hitting the controller method as many times as you need. For example in jQuery:
$(document).ready(function () {
RefreshPartial();
window.setInterval(RefreshPartial, 10000);
});
function RefreshPartial() {
$('#container').load('/some/controller/endpoint', {parameters});
}
This will call the controller method, and set the inner contents of the element identified with #container. You can call RefreshPartial as many times as you want.
Partial views only exist on the server. The only way to "refresh" the partial is to go back to the server to get it again.
Obviously, you must be doing something in the partial that needs refreshing. Whatever that is, should be callable from javascript to do the refresh.
