How can I select YUI node with this keyword?
Example:
<a href='javascript:test(this);'>Click Me!</a>
<script>
function test(el){
YUI().use('transition', function (Y) {
var selectedElement = Y.one(el);
});
}
</script>
Thanks a lot for help.
In your code, "this" will refer to the Window object, not the link. A better way to do this in YUI is:
Click Me!
<script>
YUI().use('transition', function(Y) {
Y.one('#my-link').on('click', function(e) {
e.halt();
var selectedElement = e.target;
});
});
</script>
This avoid JavaScript embedded in the markup, which is considered best practice. Also, it wraps all your code in the YUI sandbox, which is the recommended way.

I am using jQuery 2.1.1, and have been using it to add 'clickable' to rows returned from a database using this:
<script type="text/javascript">
jQuery( function($) {
$('tbody tr[data-href]').addClass('clickable').click( function() {
window.location = $(this).attr('data-href');
});
});
</script>
That has been working fine. I have now added jquery-ias (2.1.2), and only the first page of returned results has clickable rows.
My jquery-ias code is as follows:
<script type="text/javascript">
$(document).ready(function() {
// Infinite Ajax Scroll configuration
jQuery.ias({
container : '.wrap', // main container where data goes to append
item: '.item', // single items
pagination: '.nav', // page navigation
next: '.nav a', // next page selector
negativeMargin: 250,
});
});
</script>
Jquery-ias is working fine, the pages are loading as needed, but the resultant rows are not clickable.
Inspecting the page in Chrome shows that the subsequently loaded rows have not had the clickable attribute added.
The relevant row in the php is this:
<tr class='resultsrow item' <?php echo "data-href='carddetail.php?setabbrv={$row['setcode']}&number={$row['number']}&id={$row[1]}'"; ?>>
All works fine if I use either, but how do I get them to play nicely together?
EDIT.....
OK, I have worked around it using the jquery-ias built-in pageChange event.
jQuery.ias().on('pageChange', function(pageNum, scrollOffset, url) {
var delay=1000;
setTimeout(function(){
jQuery( function($) {
$('tbody tr[data-href]').addClass('clickable').click( function() {
window.location = $(this).attr('data-href');
});
});
},delay);
});
This way when ias finds a page change, it waits a second for the page structure to load, and then applies the clickable class.
I can't see this working if it's waiting for images though... doesn't have to for this instance, but there's got to be a better way to do this.
Any pointers?
the better way would be to use the rendered event, for example:
jQuery.ias().on('rendered', function(item) {
var $items = jQuery(items);
$items.each(function() {
jQuery('tr[data-href]', $this).addClass('clickable').click(function() {
window.location = $(this).attr('data-href');
});
});
});
Not sure if this is possible but I'm trying, and keep coming up short.

I want a 'E' (element) directive that is replaced with a more complex nested HTML node using the 'templateUrl' feature of directives.
HTML defining the directive (form tag included for complete mental image):
<form id="frm" name="frm">
<ds-frm-input-container
class="col-md-1"
frm-Name="frm"
frm-obj="frm"
input-name="txtFName"
ds-model="user.firstName"></ds-frm-input-container>
</form>
TemplateUrl contents which 'replaces' the above directive 'ds-frm-input-container' HTML element:
<div>
<input
required
ng-minlength=0
ng-maxlength=50
class="form-control"
ng-model="dsModel"
placeholder="{{dsPlaceHolder}}" />
<span ng-if="showErrs" class="label label-danger">FFFFF: {{dsModel}}</span>
</div>
Controller and Directive:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = "Nacho";
$scope.user = {};
$scope.user.firstName = "";
})
.directive('dsFrmInputContainer', function(){
var ddo = {
priority: 0,
restrict: 'AE',
scope:
{
frmName: '#',
inputName: '#',
dsPlaceHolder: '#',
dsModel: '=',
frmObj: '='
},
templateUrl: 'template1.html',
replace: true,
controller: function($scope)
{
$scope.showErrs = true;
},
compile: function compile(ele, attr) {
return {
pre: function preLink(scope, ele, attr, controller)
{
},
post: function postLink(scope, ele, attr, controller)
{
var txt = ele.find('input');
txt.attr('id', scope.inputName);
txt.attr('name', scope.inputName);
//BLUR
txt.bind('blur', function () {
console.log("BLUR BLUR BLUR");
angular.forEach(scope.frmObj.$error, function(value, key){
var type = scope.frmObj.$error[key];
for(var x=0; x < type.length; x++){
console.log(type[x]);
}
});
event.stopPropagation();
event.preventDefault();
});
}
};
},
};
return ddo;
});
The directive replaces just fine and the input element is named just fine. The form object however doesn't include the input element name in the error information. This makes it impossible for me to single out the input element during a 'blur' event that is setup in the directive.
I am doing this trying to reduce the show/hide logic 'noise' in the html for error messages (spans) and it should be reusable.
UPDATE (2014.01.28):
2014.01.28:
Added promises. There is a service that allows validation on button clicks. NOT USING built in angular validation anymore found some compatibility issues with another library (or viceversa).
ORIGINAL:
Here is my form validation directive vision completed (plnkr link below). Completed in concert with the help of the stack overflow community. It may not be perfect but neither are butterfingers but they taste good.
http://plnkr.co/edit/bek8WR?p=info
So here is a link that has the name variables set as expected on the given input form error object. http://plnkr.co/edit/MruulPncY8Nja1BUfohp?p=preview
The only difference is that the inputName is read from the attrs object and is not part of the scope. This is then read before the link function is returned, in the compile phase, to set the template DOM correctly.
I have just spent quite a while trying to sort this problem out, and while this is not exactly what you were looking for, his is my attempt. It uses bootstrap for all the styling, and allows for required and blur validation, but its definitely not finished yet. Any thoughts or advice much appreciated.

I'm new with Angular.js and reading i know angular dont have events like tap, double tap, etc. I'm trying to combine with Hammer.js without success.
Code from gist
/**
* angular-hammer.js
* Inspired by AngularJS' implementation of "click dblclick mousedown..."
*
* This ties in the Hammer events to attributes like:
*
* hm-tap="add_something()"
* hm-swipe="remove_something()"
*
* and also has support for Hammer options with:
*
* hm-tap-opts="{hold: false}"
*
* or any other of the "hm-event" listed underneath.
*/
angular.forEach('hmTap:tap hmDoubletap:doubletap hmHold:hold hmTransformstart:transformstart hmTransform:transform hmTransforend:transformend hmDragstart:dragstart hmDrag:drag hmDragend:dragend hmSwipe:swipe hmRelease:release'.split(' '), function(name) {
var directive = name.split(':');
var directiveName = directive[0];
var eventName = directive[1];
angular.module('MYMODULE').directive(directiveName,
['$parse', function($parse) {
return function(scope, element, attr) {
var fn = $parse(attr[directiveName]);
var opts = $parse(attr[directiveName + 'Opts'])(scope, {});
element.hammer(opts).bind(eventName, function(event) {
scope.$apply(function() {
console.log("Doing stuff", event);
fn(scope, {$event: event});
});
});
};
}]);
});
now i've added to my html file
<!--...-->
<script src="/js/jquery-1.9.0.js"></script>
<script src="/js/angular.js"></script>
<script src="/js/hammer.js"></script>
<script src="/js/jquery.hammer.js"></script>
<script src="/js/angular-hammer.js"></script>
<script src="/js/app/controllers.js"></script>
</html>
But when i try to use in my html it doesn't work.
I've tried with
<li hmTap="click($event)">...</li>
<li ngTap="click($event)">...</li>
<li hm-tap="click($event)">...</li>
<li ng-tap="click($event)">...</li>
no one works, can help me with this trouble?
Give this a go.
Add hammer.js and jquery.hammer.js to your solution. With JQuery and Angular.
Something like this:
<script src="js/jquery/jquery.min.js"></script>
<script src="js/hammer/hammer.js"></script>
<script src="js/hammer/jquery.hammer.js"></script>
<script src="js/angular/angular.min.js"></script>
Then use Angular directives to define new HTML attributes.
In this example I am creating a new attribute called on-tap
angular.module('myApp.directives', [])
.directive('onTap', function () {
return function (scope, element, attrs) {
return $(element).hammer({
prevent_default: false,
drag_vertical: false
})
.bind("tap", function (ev) {
return scope.$apply(attrs['onTap']);
});
};
});
You can then create a directive per Hammer event:
hold, tap, doubletap, transformstart, transform, transformend, dragstart, drag, dragend, release, swipe.
Your HTML would then look like this:
<button on-tap="DoAngularMethod()">Tap me</button>
Here is exactly what are you looking for:
https://github.com/wzr1337/angular-gestures
this new libary allows you to implement all of gestures you need.

Hope you find it interesting.
:)
There are some hammer directive implementations for Angular you could try to use:
https://github.com/randallb/angular-hammer
https://github.com/dreame4/angular-hammer
I used randallb lib and i added
'hmPan:pan',
'hmPanLeft:panleft',
'hmPanRight:panright',
in the hmGestures array, so i can use pan too!
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 ..
<html>
<head>
<title> Tree Structure </title>
<link rel="stylesheet" href=/dojo/dijit/themes/ claro/claro.css" />
<script type="text/javascript" src="/ dojo/dojo/dojo.js"
djConfig="parseOnLoad:true, isDebug:true" >
</script>
<script type="text/javascript">
dojo.require("dojo.parser");
dojo.require("dijit.layout.ContentPane");
dojo.require("dijit.layout.BorderContainer");
dojo.require("dijit.layout.TabContainer")
dojo.require("dijit.form.Button");
dojo.require("dojo.data.ItemFileReadStore");
dojo.require("dijit.tree.ForestStoreModel");
dojo.require("dijit.Tree");
dojo.require("dojo.parser");
function myTree( domLocation ) {
var store = new dojo.data.ItemFileReadStore({url: "http://localhost/CMTaSS_module1.0/public/dojo/cbtree/datastore/Family-1.7.json"});
var treeModel = new dijit.tree.TreeStoreModel({
store: store,
query: { name:'John'}
});
var tree = new dijit.Tree( {
model: treeModel,
id: "mytree",
openOnClick: true
});
tree.placeAt( domLocation );
}
var tree_obj = new dijit.Tree({
model: treeModel
},
"tree_obj");
dojo.connect(tree_obj, 'onClick', function(item, node, evt){
console.log("Item", item);
console.log("Node", node);
console.log("Event", evt);
//console.log('node: ' +tree_obj.getLabel(node));
//console.log('event: ' +tree_obj.getLabel(evt));
console.log('identifier: ' + tree_obj.getLabel(item))
});
</script>
</head>
<body class="claro"><br><br><br>
<div id="CheckboxTree">
<script type="text/javascript">
myTree("CheckboxTree");
</script>
</div>
</body>
</html>
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.
Looking for some insight into this problem.
I have dynamically generated links on a page that launch a lightbox ie they use a rel="lightbox[...]" I'm also putting a class on the hyperlink to make a tooltip work.
<a id="a_-1_6" class="Tips2" href="/media/63/forest_150.jpg" rel="lightbox[examples]" data-title="Tractor" data-desc="description..." data-rel="std" title="" style="opacity: 1; visibility: visible;">
And in the dom ready event
var Tips2 = new Tips($$('.Tips2'), {
initialize: function() { this.tip.fade('hide'); },
onShow: function(tip) { tip.fade('in'); },
onHide: function(tip) { tip.fade('out'); }
});
This all works fine except the tip uses the rel attribute to store data, i'm presuming as its a pre-html5 - so my question is would this mean I need to make my own version of the Tips class in mootools to work off the data.* attributes? I'd like to see I'm not barking up the wrong tree before I try that.
Thanks
Could you make another element inside the Ahref, like:
<a id="a_-1_6" href="/media/63/forest_150.jpg" rel="lightbox[examples]" data-title="Tractor" data-desc="description..." data-rel="std" title="" style="opacity: 1; visibility: visible;">
<span class="Tips2">blah</span>
</a>
This way, you can avoid the conflict.
Tips' documentation states that you can change which property is checked for the tip text. By default, it is rel or href, but you can change it when initializing the new Tip:
var Tips2 = new Tips($$('.Tips2'), {
initialize: function() { this.tip.fade('hide'); },
onShow: function(tip) { tip.fade('in'); },
onHide: function(tip) { tip.fade('out'); },
text: 'data-text' // Will now check the data-text property for tooltip text
});
