How to set start time for primefaces clock widget? - jsf-2

Is it possible to set start time for PrimeFaces clock widget?
I know about Analog Clock from PrimeFaces Extensions, but I need digital clock with this option.
I have tried to override javascript method for this clock, but it doesn't work.
PrimeFaces.widget.Clock = PrimeFaces.widget.BaseWidget.extend({
init: function(cfg) {
this._super(cfg);
this.cfg.value = 1430304817141;
this.current = this.isClient() ? new Date() : new Date(this.cfg.value);
var $this = this;
},
isClient: function() {
return this.cfg.mode === 'client';
},
});

The first problem was that you were overriding the widget too late, after PrimeFaces has instantiated its original unmodified widget. According to PrimeFaces Customizable Resource Ordering the right place to override would be in h:head.
The second problem is that you're overriding the widget with a crippled version, that doesn't contain many necessary functions that were present in the original widget.
I wouldn't recommend this approach at all - to basically break the whole PrimeFaces widget like that. What if you'd want to use the normal unchanged clock? Copy-pasted code is harder to maintain too. I advise going the more localized approach: tweak only a single widget instance.
<p:clock id="my_clock" />
<script>
// get widgetVar via EL function, since p:clock doesn't have the widgetVar attribute
var myClockVar = #{p:widgetVar('my_clock')};
myClockVar.current = new Date(1430304817141);
</script>
Just be careful not to update the clock with AJAX requests, or it will to reset to showing client time; and not to update the script, or the clock will reset to the specified time again.

Highcharts - SetState (inactive) not working after redraw

Consider the following toy example: jsfiddle
chart: {
events: {
render: myfunc
}
},
...
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
The intended behavior is to set the state of the first series as hover while setting all other series as inactive after load and redraw events.
The code works as intended after load
However, it doesn't work after redraw (via the select box). After selecting an option in the box, the series are rendered as normal instead of as inactive UNLESS any series had been previously hovered. That is, the code works if you interact with any series AND THEN select an option in the box, but it doesn't work if you select an option in the box immediately after the loading without interacting on the series.
Surprisingly, after some inspection in the console, I noted that in any case the intended states are properly passed to the series object. So, why the states are not properly rendered?
*NOTE: In my actual application the hovered series is not necessarily the first one, but it varies depending on the output of other function. I'm aware that "myfunc" could be simplified in the current example, but for general purposes please suggest an answer keeping the basic structure if possible.
This seems to be related to this issue from HighChart's GitHub. In your case, HighCharts is correctly updating the series' state. However, while rendering it fails to set the proper opacity value associated with the 'inactive' state. The workaround is to explicitly set the opacity of the series to the same value it should have in the 'inactive' state.
// F U N C T I O N S E T S T A T E
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
//explicit opacity
s.opacity = 0.2;
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
Thank you for sharing this issue, it seems that it is a regression after the last release.
In the previous version it used to work fine: https://jsfiddle.net/BlackLabel/Lbpvdwam/
<script src="https://code.highcharts.com/8.1.0/highcharts.js"></script>
<script src="https://code.highcharts.com/8.1.0/highcharts-more.js"></script>
I reported it on Highcharts Github issue channel where you can follow this thread: https://github.com/highcharts/highcharts/issues/13719
If you don't need any new features/bugfixes use the previous version as a temporary workaround.

Is it possible to add buttons and control its event to toolbar of inappbrowser using javascript...?

I am developing a Hybrid App for iOS and Android using PhoneGap.Is it possible to add buttons and control its event to toolbar of inappbrowser using javascript.I know how to add it through ios native side but i cant use that process.I need to control the button event through a javascript method.
You have two options to do that.
The first option is, obviously, to patch the native plugin code, and that's it. Here you can find an example made for iOS, you will have to do the same to your Android Java code and for every other platform you want to support.
Another option is to hide the native toolbar and inject HTML and CSS to create a new one when the page is loaded.
Something like this:
// starting inappbrowser...
inAppWindow = window.open(URL_TO_LOAD, '_blank', 'location=no');
// Listen to the events, we need to know when the page is completely loaded
inAppWindow.addEventListener('loadstop', function () {
code = CustomHeader.html();
// Inject your JS code!
inAppWindow.executeScript({
code: code
}, function () {
console.log("injected (callback).");
});
// Inject CSS!
inAppWindow.insertCSS({
code: CustomHeader.css
}, function () {
console.log("CSS inserted!");
});
And you will have obviously to define the CustomHeader object, something like this:
var CustomHeader = {
css: '#customheader { your css here }',
html: function() {
var code = 'var div = document.createElement("div");\
div.id = "customheader";\
// Insert it just after the body tag
if (document.body.firstChild){ document.body.insertBefore(div, document.body.firstChild); } \
else { document.body.appendChild(div); }';
return code;
}
};
I had experience with this problem.
For my case, the second option was enough, not a critical task. Sometimes it takes a lot for the loadstop event to fire, and so you don't see the injected bar for >= 5 seconds.
And you have to pay attention even on the CSS of the loaded page, because obviously you can affect the original CSS, or the original CSS can affect the style of your toolbar.

Why do I lose draggable after drag?

I just migrated to backbone and have a strange behaviour.
I attach draggable to an element which is created by a script, thus not directly available in DOM.
EDIT:
The element that is created is .nav, $("#viewer") as container is already in the DOM.
In plain jQuery i used .on and mousemove event for this and it worked.
With backbone I use the same in the initialize method:
initialize: function(options) {
this.viewer = $("#viewer");
this.viewer.on("mousemove", '.nav', function() {
$(this).draggable();
});
This seems to work, but only one time.
After dragging the element one time, I can't drag it anymore.
Are there conflicts with the events? Am I missing something?
You have to refer to $('#viewer') after you've called render(). initialize is called before render, and so the DOM element doesn't exist.
Also, use this.$('#viewer'), and it will grab the element (after render) even if it hasn't been appended to your page's DOM.
myView = new ExampleView({ model: myModel });
$(body).append(myView.render().el);
myView.onRender();
// -------------
// Now on your view:
onRender: function() {
this.viewer = this.$('#viewer');
this.viewer.on("mousemove", '.nav', function() {
$(this).draggable();
});
},
UPDATE
You can also, to make such things simpler, customize Backbone to automatically call the onRender() function after rendering, by triggering an event or something.
Marionette.js (a Backbone.js extension) has this built in and I use it all the time.
The solution finally was pretty easy:
make sure you dont use outdated versions of backbone.js and underscore!!
After i updated the versions to latest I made it work with:
render: function() {
this.viewer.on("mouseover", '.nav', function() {
if (!$(this).data("init")) {
$(this).data("init", true);
$(this).draggable();
}
});
Probably still not very elegant but i couldnt made the suggested onRender method from dc2 work.

JQM - Inject dynamic content at load time only

I'm trying to dynamically populate a select tag at load time (latest jQM version) using a custom template filling function.
If the fn is called in the "pagebeforechange" event, the select tag is properly initialized. Since this event is called on every page transition, I thought of moving the fn to the 'pageinit' event. This does not work, presumably because the DOM is not yet fully available. How can I coerce jQM to inject content in a page only once? Currently, I am using a kludge. There surely must be a smarter way. Thanks for any suggestions.
$(document).bind('pageinit', function () {
InitSelTagTest("#selActTag", "tplTag"); // Does not work.
});
$(document).bind("pagebeforechange", function (e, data) {
if ($("#selActTag").children().size() === 0) {
InitSelTagTest("#selActTag", "tplTag"); // Kludge, but it works
}
});
function InitSelTagTest(el,tpl) { // Append all tags to element el
var lstAllTags = JSON.parse($("#hidTag").val()); // Create tag array
// Retrieve html content from template.
var cbeg = "//<![" + "CDATA[", cend = "//]" + "]>";
var rslt = tmpl(tpl, { ddd: lstAllTags }).replace(cbeg, ").replace(cend,");
$(el).html(rslt).trigger("create"); // Add to DOM.
}
EDIT
In response to Shenaniganz' comment, it seems that the "pagebeforecreate" event could do the trick ie.
$("#pgAct").live("pagebeforecreate", function () {
// Populate tag select. Works. Traversed only once.
InitSelTag("#selActTag", "tplTag");
});
I'm not sure I fully understand your question but I'll throw a few things out there and you let me know if I can extend further.
To make something trigger only once on page load you can try to implement a regular JQuery $(document).ready(function(){}) aka $(function(){}) for the exact reason why JQuery Mobile users are told not to use it. It triggers only once on DOM load. Further pages don't trigger it because they're being switched via Ajax.
Other than that, on regular dynamic content loading you take a look at the following example I put together for someone else earlier:

can't get a ff extension to work in v3.0.5

Does anyone know what might have changed since v3.0.5 that would enable extensions to work? Or, maybe I'm missing a setting somewhere? I wrote this add-on that works fine with newer versions, but I can't get it to launch in older ones. Specifically, I can't even get this part to work (this is in my browser overlay.xul):
<html:script>
<![CDATA[
var Cc = Components.classes;
var Ci = Components.interfaces;
var obSvc = Cc["#mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
gBrowser.consoleService = Cc["#mozilla.org/consoleservice;1"].getService(Ci.nsIConsoleService);
gBrowser.log = function(msg){
this.consoleService.logStringMessage(msg);
}
gBrowser.newObj= new MyAddOn();
gBrowser.log("initializing...");
function regListener()
{
obSvc.addObserver(gBrowser.newObj, "http-on-modify-request", false);
}
function unregListener()
{
obSvc.removeObserver(gBrowser.newObj, "http-on-modify-request");
}
window.addEventListener("load", regListener, false);
window.addEventListener("unload", unregListener, false);
]]>
This should attach listeners to the new obj (defined by a linked .js) However, I'm not even getting the "initializing..." message in the console. Any ideas?
Don't use <html:script>, use <script> (assuming you have xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" on your root <overlay> element).
Don't register an application-global listener (http-on-modify-request) from a window overlay. Doing so will make your code run one time in each window the user may have open. Use an XPCOM component instead - https://developer.mozilla.org/en/Setting_HTTP_request_headers
Don't pollute common objects (like gBrowser or the global object (with var Cc)) with your own properties. If everyone did that, no two extensions would work together. Put all your code properties on your own object with a unique name.
accessing gBrowser before the load event is probably what's causing your specific problem.
Set up your environment and check the Error Console to debug problems.
Don't waste time trying to support Firefox 3. It's not supported by Mozilla itself for over a year and shouldn't be used to access the web.
It looks like gBrowser.log is not defined, or at least is not a function, as the error console will probably tell you. I've never heard of it either. Maybe it was added in Fx 3.5?
