New to coding in general, was wondering if its possible to change a content of a variable and update it to the UI with replace() or change()? I believe its much more harder than that but I can't wrap my head around it.
(function(thisObj) {
scriptBuildUI(thisObj)
function scriptBuildUI(thisObj) {
var win = (thisObj instanceof Panel) ? thisObj : new Window("palette", "replaceTest", undefined, 0);
win.alignChildren = ['center','top'];
var myTab = win.add("panel", undefined);
var replacebutton = myTab.add("button",undefined,"Replace");
var myTab2 = "x";
replacebutton.onClick = function(){ myTab2.replace("x",function(){hO()}) };
function hO() {myTab.add("button", undefined,"Retgf")};
win.onResizing = win.onResize = function() {
this.layout.resize();
};
win instanceof Window
? (win.center(), win.show()) : (win.layout.layout(true), win.layout.resize());
}
})(this);
I am not sure what you try to do here. myTab2 is a string variable and .replace() is a string function there. It returns a string. So you are trying to replace the "x" with the content of the function? To what end?
Also, the way i see it, that would just add another button to myTab.
If you could tell me what you try to do, maybe we can find a work-around.
Edit: To just assign your function to myTab2, you can directly do that. And if you want changes to your UI, i think you need to run win.layout.layout(true); to make them vissible. The folowing code adds a button to your tab every time it's clicked.
(function(thisObj) {
scriptBuildUI(thisObj)
function scriptBuildUI(thisObj) {
var win = (thisObj instanceof Panel) ? thisObj : new Window("palette", "replaceTest", undefined, 0);
win.alignChildren = ['center','top'];
var myTab = win.add("panel", undefined);
var replacebutton = myTab.add("button",undefined,"Replace");
var myTab2 = "x";
replacebutton.onClick = function(){ myTab2=hO() };
function hO() {
myTab.add("button", undefined,"Retgf");
win.layout.layout(true);
};
win.onResizing = win.onResize = function() {
this.layout.resize();
};
win instanceof Window
? (win.center(), win.show()) : (win.layout.layout(true), win.layout.resize());
}
})(this);

I have several charts built with dc.js. I can achieve the desired functionality by attaching a callback to each dc.js chart's .on("filterted", function(chart) {}) but this is annoying because I have to attach the same callback to each chart. And error prone because as new charts are added, someone has to remember to attach an event hander. I would prefer to just attach a callback to the underlying crossfilter. Is that possible?
Is there a way to optimize this...
var ndx = crossfilter(data);
var dimAlpha = ndx.dimension(function(d) {return d.alpha});
var dimBeta = ndx.dimension(function(d) {return d.beta});
var groupAlpha = dimAlpha.group().reduceSum(function(d) {return 1;});
var groupBeta = dimBeta.group().reduceSum(function(d) {return 1;});
dc.pieChart(myDomId1)
.dimension(dimAlpha)
.group(groupAlpha)
.on("filtered", function(chart) {
//do stuff
});
dc.pieChart(myDomId2)
.dimension(dimBeta)
.group(groupBeta)
.on("filtered", function(chart) {
//do stuff
});
into something like this...
var ndx = crossfilter(data);
var dimAlpha = ndx.dimension(function(d) {return d.alpha});
var dimBeta = ndx.dimension(function(d) {return d.beta});
var groupAlpha = dimAlpha.group().reduceSum(function(d) {return 1;});
var groupBeta = dimBeta.group().reduceSum(function(d) {return 1;});
dc.pieChart(myDomId1)
.dimension(dimAlpha)
.group(groupAlpha);
dc.pieChart(myDomId2)
.dimension(dimBeta)
.group(groupBeta);
ndx.on("filtered", function() {
//do stuff
})
If you've got a million charts and don't want to have to attach the event listener to each one manually, you could iterate through the chart registry and add them that way. Ex:
dc.chartRegistry.list().forEach(function(chart) {
chart.on('filtered', function() {
// your event listener code goes here.
});
});
Note that this code must go after the charts have instantiated to work.
In the absence of a way to attach the callback once globally, one thing you could do to mitigate the risk from duplicate code is to define the callback function once and pass in a reference instead of defining it inline on each chart.
function my_func() {
// do stuff
}
dc.pieChart(myDomId2)
.dimension(dimBeta)
.group(groupBeta)
.on("filtered", my_func);
chart and filter can also be passed to the filter function something like:
function my_func(chart,filter) {
// do stuff
}
dc.pieChart(myDomId2)
.dimension(dimBeta)
.group(groupBeta)
.on("filtered", my_func);
I have been trying to create a Placemark that I can hide and show (like turning visibility on and off) on demand (on click)... I am using this to make the placemark:
function placemark(lat, long, name, url, iconsrc){
var placemark = ge.createPlacemark(name);
ge.getFeatures().appendChild(placemark);
placemark.setName(name);
// Create style map for placemark
var icon = ge.createIcon('');
if(iconsrc == "0")
icon.setHref('http://maps.google.com/mapfiles/kml/paddle/red-circle.png');
else{
icon.setHref(iconsrc);
}
var style = ge.createStyle('');
style.getIconStyle().setIcon(icon);
if(iconsrc != "0")
style.getIconStyle().setScale(2.5);
placemark.setStyleSelector(style);
// Create point
var point = ge.createPoint('');
point.setLatitude(lat);
point.setLongitude(long);
//point.setAltitudeMode(1500);
placemark.setGeometry(point);
google.earth.addEventListener(placemark, 'click', function(event) {
// Prevent the default balloon from popping up.
event.preventDefault();
var balloon = ge.createHtmlStringBalloon('');
balloon.setFeature(placemark); // optional
balloon.setContentString(
'<iframe src="'+ url +'" frameborder="0"></iframe>');
ge.setBalloon(balloon);
});
}
I have tried everything... from this:
function hidePlacemark(name){
var children = ge.getFeatures().getChildNodes();
for(var i = 0; i < children.getLength(); i++) {
var child = children.item(i);
if(child.getType() == 'KmlPlacemark') {
if(child.getId()== name)
child.setVisibility(false);
}
}
}
to using this ge.getFeatures().removeChild(child);
can anyone point me to the right direction on creating a function that will allow me to turn the visibility on/off on demand please.
Your hidePlacemark function is missing some {} in your final IF statement
if(child.getId()== name)
you have
function hidePlacemark(name){
var children = ge.getFeatures().getChildNodes();
for(var i = 0; i < children.getLength(); i++) {
var child = children.item(i);
if(child.getType() == 'KmlPlacemark') {
if(child.getId()== name)
child.setVisibility(false);
}
}
}
make it
function hidePlacemark(name){
var children = ge.getFeatures().getChildNodes();
for(var i = 0; i < children.getLength(); i++) {
var child = children.item(i);
if(child.getType() == 'KmlPlacemark') {
if(child.getId()== name) {
child.setVisibility(false);
}
}
}
}
HOWEVER ------- you are better off doing this as it is much faster as you don't need to loop through ALL your placemarks
function hidePlacemark(name) {
var placemark = ge.getElementById(name);
placemark.setVisibility(false);
}
I think the plain ge.getFeatures().removeChild(placemark); works.
I played with this GooglePlayground, and just added the following code to line 8 (that is empty in this GooglePlayground Sample):
addSampleButton('Hide Placemark', function(){
ge.getFeatures().removeChild(placemark);
});
Clicking the button Hide Placemark hides the placemark like a charm here. Any chances your problem is somewhere else in your code?
I already added a stop button with autoplay but I need to make it so when you click the button again after you had stopped it, the music starts playing.
Source code:
var music:Sound = new Sound(new URLRequest("calmingsong.mp3"));
var sc:SoundChannel = music.play();
button1.addEventListener(MouseEvent.CLICK, stopMusic);
function stopMusic(e:Event):void
{
sc.stop();
}
If you just want to play the sound over from the beginning, just call the Sound object's play() method again (you get a new SoundChannel object when you do this).
If you'd like to resume playing the sound at the point where the user stopped it, you'll need to add additional variables to store the current "playback state"... Something like this:
var music:Sound = new Sound(new URLRequest("calmingsong.mp3"));
var sc:SoundChannel = music.play();
var startPosition:Number = 0;
var isPlaying = true; // default to true cause you auto play...
button1.addEventListener(MouseEvent.CLICK, togglePlayback);
function togglePlayback(e:Event):void
{
if (isPlaying)
{
startPosition = sc.position;
sc.stop();
isPlaying = false;
}
else
{
sc = music.play(startPosition);
isPlaying = true;
}
}
I would like to know how to detect when no buttons are pressed on a movieclip,
such as
if (no keys are pressed){
this.gotoAndStop("idle");
}
Firstly if you expand your question as you expand your purpose of what you achieve, maybe I can present a more in depth solllution ... ;) I can not imagine why you need a no buttons pressed event. Anyway you can use this code snippet.
//This belongs to no button pressed event.
var def = 0;
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
def = 1;
};
keyListener.onKeyUp = function() {
def = 0;
};
Key.addListener(keyListener);
//First Part for the whole movie clip
_root.onEnterFrame = function (){
trace(def);
if(def == 1){
this.gotoAndStop("idle");
}
}
Scenario: I have a standard dropdown list and when the value in that dropdownlist changes I want to update another dropdownlist that exists in a tinyMCE control.
Currently it does what I want when I open the page (i.e. the first time)...
function changeParent() {
}
tinymce.create('tinymce.plugins.MoePlugin', {
createControl: function(n, cm) {
switch (n) {
case 'mylistbox':
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts',
onselect: function(v) {
tinyMCE.execCommand("mceInsertContent",false,v);
}
});
<% foreach (var insert in (ViewData["Inserts"] as List<String>)) { %> // This is .NET
yourobject = '<%= insert %>'; // This is JS AND .NET
mlb.add(yourobject, yourobject); // This is JavaScript
<% } %>
// Return the new listbox instance
return mlb;
}
return null;
}
});
<%= Html.DropDownList(Model.Record[184].ModelEntity.ModelEntityId.ToString(), ViewData["Containers"] as SelectList, new { onchange = "changeParent(); return false;" })%>
I am thinking the way to accomplish this (in the ChangeParentFunction) is to call a controller action to get a new list, then grab the 'mylistbox' object and reassign it, but am unsure how to put it all together.
As far as updating the TinyMCE listbox goes, you can try using a tinymce.ui.NativeListBox instead of the standard tinymce.ui.ListBox. You can do this by setting the last argument to cm.createListBox to tinymce.ui.NativeListBox. This way, you'll have a regular old <select> that you can update as you normally would.
The downside is that it looks like you'll need to manually hook up your own onchange listener since NativeListBox maintains its own list of items internally.
EDIT:
I played around a bit with this last night and here's what I've come up with.
First, here's how to use a native list box and wire up our own onChange handler, the TinyMCE way:
// Create a NativeListBox so we can easily modify the contents of the list.
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts'
}, tinymce.ui.NativeListBox);
// Set our own change handler.
mlb.onPostRender.add(function(t) {
tinymce.dom.Event.add(t.id, 'change', function(e) {
var v = e.target.options[e.target.selectedIndex].value;
tinyMCE.activeEditor.execCommand("mceInsertContent", false, v);
e.target.selectedIndex = 0;
});
});
As far as updating the list box at runtime, your idea of calling a controller action to get the new items is sound; I'm not familiar with ASP.NET, so I can't really help you there.
The ID of the <select> that TinyMCE creates takes the form editorId_controlId, where in your case controlId is "mylistbox". Firebug in Firefox is the easiest way to find the ID of the <select> :)
Here's the test button I added to my page to check if the above code was working:
<script type="text/javascript">
function doFoo() {
// Change "myEditor" below to the ID of your TinyMCE instance.
var insertsElem = document.getElementById("myEditor_mylistbox");
insertsElem.options.length = 1; // Remove all but the first option.
var optElem = document.createElement("option");
optElem.value = "1";
optElem.text = "Foo";
insertsElem.add(optElem, null);
optElem = document.createElement("option");
optElem.value = "2";
optElem.text = "Bar";
insertsElem.add(optElem, null);
}
</script>
<button onclick="doFoo();">FOO</button>
Hope this helps, or at least gets you started.
Step 1 - Provide a JsonResult in your controller
public JsonResult GetInserts(int containerId)
{
//some code to get list of inserts here
List<string> somedata = doSomeStuff();
return Json(somedata);
}
Step 2 - Create javascript function to get Json results
function getInserts() {
var params = {};
params.containerId = $("#184").val();
$.getJSON("GetInserts", params, updateInserts);
};
updateInserts = function(data) {
var insertsElem = document.getElementById("183_mylistbox");
insertsElem.options.length = 1; // Remove all but the first option.
var optElem = document.createElement("option");
for (var item in data) {
optElem = document.createElement("option");
optElem.value = item;
optElem.text = data[item];
try {
insertsElem.add(optElem, null); // standards compliant browsers
}
catch(ex) {
insertsElem.add(optElem, item+1); // IE only (second paramater is the items position in the list)
}
}
};
Step 3 - Create NativeListBox (code above provided by ZoogieZork above)
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts'
}, tinymce.ui.NativeListBox);
// Set our own change handler.
mlb.onPostRender.add(function(t) {
tinymce.dom.Event.add(t.id, 'change', function(e) {
var v = e.target.options[e.target.selectedIndex].value;
tinyMCE.activeEditor.execCommand("mceInsertContent", false, v);
e.target.selectedIndex = 0;
});
});
//populate inserts on listbox create
getInserts();
