i am new to Zend framework and dojo.i have created dynamic tree structure using dojo in zend framework but i want to make on click of each folder and element of tree structure to naigation to another form by writing a function .Pleas check my code and help me i have gone through some dojo on click event link and could not solve ..

console.log("Node", node);
console.log("Event", evt);

Looks like your code sample is not formatted correctly as some of the logic is outside the myTree function. I used jsbeautifier.org to confirm this.
Other notes...
You should wait until dojo is ready. Either use dojo.addonload or, create a widget and reference that widget in the html portion of your code. Widgets are amazing and are what make dojo great, so getting a grasp on how they work will pay dividends.
Also note that if creating a widget programmatically (new dijit.Tree), you should call startup on it. This is not needed when creating it declaratively (inline html).
I hope this helps.

I implement content filter with ember.js and I need to save filter state in URL. How can I do this?
I reed this section http://guides.emberjs.com/v1.12.0/routing/query-params/ and try to do that code
http://output.jsbin.com/cixama/4
But choice saved in URL as
http://output.jsbin.com/cixama/4#/?pull=undefined
Why undefined?

Your problem is that the number property of the payload is an integer, while the query param is a string.
When you select an item from the dropdown, a numeric value gets written into the pull property. But the query params mechanism replaces it with a string. The dropdown sees the value changed, looks up a new value and finds nothing. It assumes that no value was chosen and sets pull to undefined.
One solution is to use two properties: one will store the original numeric value, the other will be a getter/setter computed property that would convert between numeric and text.
<form>
{{view "select" content=model
optionValuePath="content.number"
optionLabelPath="content.title"
value=currentPull
prompt="Choice option"}}
</form>
<p>currentPull: {{currentPull}}</p>
App.IndexController = Ember.Controller.extend({
queryParams: ['pull'],
pull: Ember.computed('currentPull', {
get: function() {
return this.get('currentPull');
},
set: function(key, value) {
this.set('currentPull', parseInt(value, 10));
return value;
},
}),
currentPull: null,
});
Demo: http://output.jsbin.com/redefi/2
But a better solution would be to introduce a model layer into your app. You'd have a pull-request entity with its attributes corresponding to properties of the payload. Then you can handle the number↔text conversion in the serializer, and your business logic will stay concise and expressive.
I've followed this tutorial:
http://popcornjs.org/popcorn-101
Tutorial Code
<!doctype html>
<html>
<head>
<script src="http://popcornjs.org/code/dist/popcorn-complete.min.js"></script>
<script>
// ensure the web page (DOM) has loaded
document.addEventListener("DOMContentLoaded", function () {
// Create a popcorn instance by calling Popcorn("#id-of-my-video")
var pop = Popcorn("#ourvideo");
// add a footnote at 2 seconds, and remove it at 6 seconds
pop.footnote({
start: 2,
end: 6,
text: "Pop!",
target: "footnotediv"
});
// play the video right away
pop.play();
}, false);
</script>
</head>
<body>
<video height="180" width="300" id="ourvideo" controls>
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.mp4">
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.ogv">
<source src="http://videos.mozilla.org/serv/webmademovies/popcornplug.webm">
</video>
<div id="footnotediv"></div>
</body>
</html>
And can run this locally.
In Firebug, I see the footnote div update from:
<div style="display: none;">Pop!</div>
to:
<div style="display: inline;">Pop!</div>
On a live site however, I am loading my page html from a MongoDB database via Ajax and the footnote display functionality doesn't seem to be working.
Thinking this might have something to do with needing to 're-initialise' after the content has loaded, I've added the popcorn.js functionality to a function called on click:
Function
<script>
function myPopcornFunction() {
var pop = Popcorn("#ourvideo");
pop.footnote({
start: 2,
end: 6,
text: "Pop!",
target: "footnotediv"
});
pop.play();
}
</script>
Call
$(document).on("click","a.video", function (e) {
// passing values to python script and returning results from database via getJSON()
myPopcornFunction();
});
This doesn't seem to have an effect.
No footnotediv content is loaded when the video plays.
The video is also not playing automatically.
It's hard to reproduce in jsFiddle with dynamic content, so is there a generic approach to ensuring popcorn works with dynamically loaded content?
Firebug Error on click
TypeError: k.media.addEventListener is not a function
It seems to have been a timing issue in that originally I had made a call to the myPopcornFunction() outside of the function which loaded the content (a getJSON() function). When I placed the call within the same block as the getJSON() function, things seemed to maintain their 'order' and popcorn could work correctly.
Before
$(document).on("click","a.video", function (e) {
$.getJSON("/path", {cid: my_variable, format: 'json'}, function(results){
$("#content_area").html("");
$("#content_area").append(results.content);
});
e.preventDefault();
myPopcornFunction(); // the call WAS here
});
After
$(document).on("click","a.video", function (e) {
$.getJSON("/path", {cid: my_variable, format: 'json'}, function(results){
$("#content_area").html("");
$("#content_area").append(results.content);
myPopcornFunction(); // the call is now HERE
});
e.preventDefault();
});
The myPopcornFunction() was the same as in the original post.
I've loaded the MapQuest JavaScript api module and am able to bring in the basic sample map at http://developer.mapquest.com/web/documentation/sdk/javascript/v7.0/basic-map but when I try to add map controls using their next example I get the JavaScript error:
map.addControl is not a function
I tried window.map.addControl but that generates the same error.
Does anyone know what might be wrong?
Thanks
You need to add the map control code within your MQA.EventUtil.observe
right after your call to window.map = new MQA.TileMap(options);
Code:
<html>
<head>
<script src="http://www.mapquestapi.com/sdk/js/v7.0.s/mqa.toolkit.js?key=Kmjtd%7Cluua2qu7n9%2C7a%3Do5-lzbgq"></script>
<script type="text/javascript">
MQA.EventUtil.observe(window, 'load', function() {
/*Create an object for options*/
var options={
elt:document.getElementById('map'), /*ID of element on the page where you want the map added*/
zoom:10, /*initial zoom level of map*/
latLng:{lat:39.743943, lng:-105.020089}, /*center of map in latitude/longitude*/
mtype:'map' /*map type (map)*/
};
/*Construct an instance of MQA.TileMap with the options object*/
window.map = new MQA.TileMap(options);
MQA.withModule('largezoom','traffictoggle','viewoptions','mousewheel', function() {
map.addControl(
new MQA.LargeZoom(),
new MQA.MapCornerPlacement(MQA.MapCorner.TOP_LEFT, new MQA.Size(5,5))
);
map.addControl(new MQA.TrafficToggle());
map.addControl(new MQA.ViewOptions());
map.enableMouseWheelZoom();
});
});
</script>
</head>
<body>
<div id='map' style='width:750px; height:280px;'></div>
</body>
</html>
try like this map.current.addControl
Make sure you add the module for the control before adding the control to the map.
I'm looking for unbind functionality in knockout. Unfortunately googling and looking through questions asked here didn't give me any useful information on the topic.
I will provide an example to illustrate what kind of functionality is required.
Lets say i have a form with several inputs.
Also i have a view model binded to this form.
For some reason as a reaction on user action i need to unbind my view model from the form, i.e. since the action is done i want all my observables to stop reacting on changes of corresponding values and vise versa - any changes done to observables shouldn't affect values of inputs.
What is the best way to achieve this?
You can use ko.cleanNode to remove the bindings. You can apply this to specific DOM elements or higher level DOM containers (eg. the entire form).
See http://jsfiddle.net/KRyXR/157/ for an example.
#Mark Robinson answer is correct.
Nevertheless, using Mark answer I did the following, which you may find useful.
// get the DOM element
var element = $('div.searchRestults')[0];
//call clean node, kind of unbind
ko.cleanNode(element);
//apply the binding again
ko.applyBindings(searchResultViewModel, element);

<span class="lengthField" data-bind="text: length"></span>
</div>
<button type='button' class="modelData1" data-bind="click:showModelData.bind($data, 'model1')">show Model Data1</button>
<button type='button' class="modelData2" data-bind="click:showModelData.bind($data, 'model2')">show Model Data2</button>
<button type='button' class="modelData3" data-bind="click:showModelData.bind($data, 'model3')">show Model Data3</button>

#Mark Robinson gave perfect solution, I've similar problem with single dom element and updating different view models on this single dom element.
Each view model has a click event, when click happened everytime click method of each view model is getting called which resulted in unnecessary code blocks execution during click event.
I followed #Mark Robinson approach to clean the Node before apply my actual bindings, it really worked well.
Thanks Robin.
My sample code goes like this.
function viewModel(name, id, length){
var self = this;
self.name = name;
self.id = id;
self.length = length;
}
viewModel.prototype = {
showModelData: function(data){
console.log('selected model is ' + data);
if(data=='model1'){
ko.cleanNode(button1[0]);
ko.applyBindings(viewModel1, button1[0]);
console.log(viewModel1);
}
else if(data=='model2'){
ko.cleanNode(button1[0]);
ko.applyBindings(viewModel3, button1[0]);
console.log(viewModel2);
}
else if(data=='model3'){
ko.cleanNode(button1[0]);
ko.applyBindings(viewModel3, button1[0]);
console.log(viewModel3);
}
}
}
$(document).ready(function(){
button1 = $(".modelBody");
viewModel1 = new viewModel('TextField', '111', 32);
viewModel2 = new viewModel('FloatField', '222', 64);
viewModel3 = new viewModel('LongIntField', '333', 108);
ko.applyBindings(viewModel1, button1[0]);
});
Is there a way to query a dojo dijit to tell if the dijit's DOM has finished loading?
I believe if the dijit's "domNode" property is set, the DOM for the widget has been created. The widget may or may not be attached to the larger DOM, that can be a separate step. Checking domNode.parentNode as being a real element might help, but it is no guarantee that parentNode is also in the live document.
I believe something like this might work, although I didn't test it :
if (yourWidget.domNode) {
// here your widget has been rendered, but not necessarily its child widgets
} else {
// here the domNode hasn't been defined yet, so the widget is not ready
}
Dijit widgets' rendering is handled through extension points, called in that order :
postMixinProperties
buildRendering
postCreate <== at this point, your widget has been turned into HTML and inserted into the page, and you can access properties like this.domNode. However, none of the child widgets has been taken care of
startup : this is the last extension point called, after all the child widgets have been drawn
(This is the explanation of the widgets' lifecycle on "Mastering Dojo").
EXAMPLE :
<html>
<head>
<script src="path/to/your/dojo/dojo.js" djConfig="parseOnLoad: true, isDebug: true"></script>
<script type="text/javascript">
dojo.require("dojo.parser");
dojo.require("dojox.lang.aspect");
dojo.require("dijit.form.Button");
// Define your aspects
var startupAspect = {
before : function() {console.debug("About to execute the startup extension point");},
after : function() {console.debug("Finished invoking the startup extension point");},
};
function traceWidget(theWidget) {
// Attach the aspect to the advised method
dojox.lang.aspect.advise(theWidget, "startup", startupAspect);
}
</script>
</head>
<body>
<button dojoType="dijit.form.Button" type=button">
dijitWidget
<script type="dojo/method" event="postCreate">
traceWidget(this);
</script>
<script type="dojo/method" event="startup">
console.debug("Inside startup");
</script>
</button>
</body>
