I am trying to build #TagFriends and comment box feature from FACEBOOK.
I found two examples that might help, I am having library issue when I import one examples library in second one, whole code fails to work, if they are executed individually they work correctly.
1.Simple comment box :
http://devzone.co.in/angularjs-example-simple-user-comment-box/
2.#Tag friend code Below:

I have implemented this feature. Find the GitHub: github.com/noob93/Smart-Comment-Box
The Devzone example is using a deprecated feature of AngularJs, I modified the code and feature started working fine.

I'm trying to update the value of an Ion.RangeSlider when its bound ng-model scope variable changes. The model updates when the Ion.RangeSlider is used, but not vice-versa. Other inputs with the same ng-model update when the model value changes, so this must be some special case.
Edit: Woo! Here's a snippet #lin :) Also jsfiddle.
var app = angular.module('ngModelIonRangeSliderDemo', []);
app.controller('MainCtrl', function ($scope, $rootScope, $timeout) {
$scope.someNumber = 10;
}).directive('ionRangeSlider', function ionRangeSlider() {
return {
restrict: 'A',
scope: {
rangeOptions: '=',
model: '=ngModel'
},
link: function (scope, elem, attrs) {
scope.$watch('model',function () {
elem.ionRangeSlider(scope.rangeOptions);
});
}
}
});

I have tried all kinds of suggestions in over ten somewhat-related stack overflow posts (which is how I have set up the current scope.$watch scheme on the ngModel), but none have worked. There aren't any errors in my console. What's wrong? Also, why doesn't it work without any mention of the model in my directive? Please let me know if there's anything important I have failed to include in this post.
Just use slider.update() inside your directive and you will be fine:
var app = angular.module('myApp', []);
app.controller('MainCtrl', function ($scope, $rootScope, $timeout) {
$scope.someNumber = 15;
$scope.apply = false;
}).directive('ionRangeSlider', function ionRangeSlider() {
return {
restrict: 'A',
scope: {
rangeOptions: '=',
model: '=ngModel',
apply: '=apply'
},
link: function (scope, elem, attrs) {
elem.ionRangeSlider(scope.rangeOptions);
scope.$watch('apply',function () {
if (scope.apply) {
scope.apply = false;
var slider = elem.data("ionRangeSlider");
slider.update({
from: scope.model
});
}
});
}
}
});

Extra demo, how binding ion.rangeSlider to input works:
http://jsfiddle.net/IonDen/r5aox84v/
var $range = $(".js-range-slider"),
$inputFrom = $(".js-input-from"),
$inputTo = $(".js-input-to"),
instance,
min = 0,
max = 1000,
from = 0,
to = 0;
$range.ionRangeSlider({
type: "double",
min: min,
max: max,
from: 200,
to: 800,
onStart: updateInputs,
onChange: updateInputs
});
instance = $range.data("ionRangeSlider");
function updateInputs (data) {
from = data.from;
to = data.to;
$inputFrom.prop("value", from);
$inputTo.prop("value", to);
}
$inputFrom.on("input", function () {
var val = $(this).prop("value");
// validate
if (val < min) {
val = min;
} else if (val > to) {
val = to;
}
instance.update({
from: val
});
});
$inputTo.on("input", function () {
var val = $(this).prop("value");
// validate
if (val < from) {
val = from;
} else if (val > max) {
val = max;
}
instance.update({
to: val
});
});
I am coding a very very basic playground by using AngularJS and ui-codemirror. Here is the code (JSBin).

<textarea ui-codemirror ng-model="css"></textarea>
</div>
Output:
<section id="output">
<iframe></iframe>
</section>
</div>
</body>
</html>
JavaScript:
var myApp = angular.module('myApp', ['ui']);
myApp.value('ui.config', {
codemirror: {
mode: 'text/x-php',
lineNumbers: true,
matchBrackets: true,
}
});
function codeCtrl($scope, codeService) {
$scope.html = '<body>default</body>';
$scope.css = "body {color: red}";
$scope.$watch('html', function () { codeService.render($scope.html, $scope.css); }, true);
$scope.$watch('css', function () { codeService.render($scope.html, $scope.css); }, true);
}
myApp.service('codeService', function () {
this.render = function (html, css) {
source = "<html><head><style>" + css + "</style></head>" + html +"</html>";
var iframe = document.querySelector('#output iframe'),
iframe_doc = iframe.contentDocument;
iframe_doc.open();
iframe_doc.write(source);
iframe_doc.close();
}
})
The above code works, but the problem is it applies one same ui.config to 2 ui-codemirror. Does anyone know how to apply mode html to the first ui-codemirror and mode css to the second ui-codemirror?
Additionally, how could I set the height (or rows) and width (or cols) of a ui-codemirror?
Since you're dealing with two separate text areas that have rather different roles (or imagine if they were more), it makes sense to define separate directives for them, each one accepting a different config object. I've created a JSBin which shows one possible approach, via directive factory that can be used to generated different "mirrors".
angular.module('codeMirrorApp')
.factory('CodeMirrorFactory', ['$parse',
function($parse) {
return {
createDirective: function(config) {
var configString = JSON.stringify(config);
return {
scope: true,
restrict: 'E',
template: '<textarea ui-codemirror=' + configString + ' ng-model="content"></textarea>',
controller: ['$scope', '$attrs', function($scope, $attrs) {
var handler = $parse($attrs.handler);
$scope.$watch('content', function(value) {
handler($scope, { content: value });
});
}]
};
}
};
}
]);
I'm intentionally using handlers provided by the parent controller instead of bindings to the parent scope as this makes things look more understandable even while looking at the HTML markup.
The controller:
angular.module('codeMirrorApp')
.controller('MirrorsController', ['RenderMirrors',
function(RenderMirrors) {
var ctrl = this,
html,
css;
ctrl.handleHtml = function(htmlString) {
html = htmlString;
RenderMirrors.render(html, css);
};
ctrl.handleCss = function(cssString) {
css = cssString;
RenderMirrors.render(html, css);
};
}
]);
Markup:
<div ng-app="codeMirrorApp">
<div ng-controller="MirrorsController as ctrl">
HTML:<br>
<html-code-mirror handler="ctrl.handleHtml(content)"></html-code-mirror>
<br>CSS:<br>
<css-code-mirror handler="ctrl.handleCss(content)"></css-code-mirror>
</div>
Output:
<section id="output">
<iframe></iframe>
</section>
</div>
Hope this helps.
Controller:
function codeCtrl($scope, codeService) {
$scope.editorOptions1 = {mode: 'text/html',
lineNumbers: false,
matchBrackets: true};
$scope.editorOptions2 = {mode: 'text/css',
lineNumbers: true,
matchBrackets: true};
$scope.html = '<body>default</body>';
$scope.css = "body {color: red}";
$scope.$watch('html', function () { codeService.render($scope.html, $scope.css); }, true);
$scope.$watch('css', function () { codeService.render($scope.html, $scope.css); }, true);
}
Html :
<div ng-controller="codeCtrl">
HTML:<br>
<textarea ui-codemirror="editorOptions1" ng-model="html"></textarea>
<br>CSS:<br>
<textarea ui-codemirror="editorOptions2" ng-model="css"></textarea>
</div>
I would like to the ui-grid row select feature to set the value of a column in the clicked row.
I have a column in the DB named omit. I would like that value to equal the state of the selected row, so if the row is selected then omit = 1, if row is not selected then omit = 0. I think I have this part figured out (however I'm always open to better ideas!).
gridApi.selection.on.rowSelectionChanged($scope,function(row){
if(row.isSelected){
row.entity.omit = 1;
}
if(!row.isSelected){
row.entity.omit = 0;
}
// now save to database...
});
gridApi.selection.on.rowSelectionChangedBatch($scope,function(rows){
angular.forEach(rows, function(value, key) {
if(value.isSelected){
value.entity.omit = 1;
}
if(!value.isSelected){
value.entity.omit = 0;
}
// now save to database...
});
});
What I haven't been able to figure out is how the select the row when the grid is first loaded.
So, on the initial load of the grid, how do I select the row if the value of omit is 1?
You can use the gridApi.selection.selectRow method, but you have to wait until the grid has digested the data for it to work. So you either have to set it on an $interval (or after a $timeout) to keep running while the grid digests the data, or you can call gridApi.grid.modifyRows($scope.gridOptions.data) before you call selectRow... to be honest, I'm not sure why you have to call that.
var app = angular.module('app', ['ngTouch', 'ui.grid', 'ui.grid.selection']);
app.controller('gridCtrl', ['$scope', '$http', '$interval', 'uiGridConstants', function ($scope, $http, $interval, uiGridConstants) {
$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false };
$scope.gridOptions.columnDefs = [
{ name: 'omit' },
{ name: 'id' },
{ name: 'name'},
{ name: 'age', displayName: 'Age (not focusable)', allowCellFocus : false },
{ name: 'address.city' }
];
$scope.gridOptions.multiSelect = false;
$scope.gridOptions.modifierKeysToMultiSelect = false;
$scope.gridOptions.noUnselect = true;
$scope.gridOptions.onRegisterApi = function( gridApi ) {
$scope.gridApi = gridApi;
gridApi.selection.on.rowSelectionChanged($scope,function(row){
if(row.isSelected){
row.entity.omit = 1;
}
if(!row.isSelected){
row.entity.omit = 0;
}
// now save to database...
});
gridApi.selection.on.rowSelectionChangedBatch($scope,function(rows){
angular.forEach(rows, function(value, key) {
if(value.isSelected){
value.entity.omit = 1;
}
if(!value.isSelected){
value.entity.omit = 0;
}
// now save to database...
});
});
};
$scope.toggleRowSelection = function() {
$scope.gridApi.selection.clearSelectedRows();
$scope.gridOptions.enableRowSelection = !$scope.gridOptions.enableRowSelection;
$scope.gridApi.core.notifyDataChange( uiGridConstants.dataChange.OPTIONS);
};
$http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/500_complex.json')
.success(function(data) {
_.forEach(data, function(row) {
row.omit = 0;
});
/* arbitrarily setting the fourth row's omit value to 1*/
data[3].omit = 1;
$scope.gridOptions.data = data;
/* using lodash find method to grab the row with omit === 1 */
/* could also use native JS filter, which returns array rather than object */
var initSelected = _.find($scope.gridOptions.data, function(row) { return row.omit === 1; });
$scope.gridApi.grid.modifyRows($scope.gridOptions.data);
$scope.gridApi.selection.selectRow(initSelected);

So I'm using Handsontable to render a grid. (Yes, I am NOT using the ngHandsontable. I started out with that but ran into problems and so I went with just rendering a Handsontable from an angularjs directive.)
I want one column to hold an anchor tag.
I want the anchor tag to have the angularjs ng-click directive.
Everything renders correctly but the ng-click is not called.
Here is my example.
var APP = angular.module('APP', ['controllers']);
angular.module('controllers',[])
.controller('testController', function ($scope) {
$scope.doNgClick = function() {
alert('ng-click');
// console.log('ng-click');
};
$scope.simple = [
{
test: "<a href='javascript:void(0);' ng-click='doNgClick()'>Test</a>"
// test: "<a ng-click='doNgClick()'>Test</a>"
}
];
});
APP.directive('htable',function($compile) {
var directive = {};
directive.restrict = 'A';
directive.scope = {
data : '='
};
directive.link = function(scope,element,attrs) {
var container = $(element);
// var safeHtmlRenderer = function (instance, td, row, col, prop, value, cellProperties) {
// var escaped = Handsontable.helper.stringify(value);
// td.innerHTML = escaped;
// return td;
// };
var settings = {
data: scope.data,
readOnly: true,
colHeaders: ['Link'],
columns: [
{
data: "test",
renderer: "html",
// renderer: safeHtmlRenderer,
readyOnly: true
}
]
};
var hot = new Handsontable( container[0], settings );
hot.render();
// console.log(element.html());
// $compile(element.contents())(scope);
};//--end of link function
return directive;
});

Someone asked a similar question (How to use ng-class in select with ng-options), but I'm adding mine too, because it's related to the answer of the other guy's question.
The solution is awesome, but I don't quite understand it.
The answer was creating a directive - http://plnkr.co/edit/rbc4GWBffi4eFYhbvS6u?p=preview.
I would like do the same, but the class added should be the same as items.name. How do I do that?
console.clear();
var app = angular.module('angularjs-starter', []);
app.controller('MainCtrl', function($scope) {
$scope.items = [
{ name: 'foo', id: 1, eligible: true },
{ name: 'bar', id: 2, eligible: false },
{ name: 'test', id: 3, eligible: true }
];
});
app.directive('optionsClass', function ($parse) {
return {
require: 'select',
link: function(scope, elem, attrs, ngSelect) {
// get the source for the items array that populates the select.
var optionsSourceStr = attrs.ngOptions.split(' ').pop(),
// use $parse to get a function from the options-class attribute
// that you can use to evaluate later.
getOptionsClass = $parse(attrs.optionsClass);
scope.$watch(optionsSourceStr, function(items) {
// when the options source changes loop through its items.
angular.forEach(items, function(item, index) {
// evaluate against the item to get a mapping object for
// for your classes.
var classes = getOptionsClass(item),
// also get the option you're going to need. This can be found
// by looking for the option with the appropriate index in the
// value attribute.
option = elem.find('option[value=' + index + ']');
// now loop through the key/value pairs in the mapping object
// and apply the classes that evaluated to be truthy.
angular.forEach(classes, function(add, className) {
if(add) {
angular.element(option).addClass(className);
}
});
});
});
}
};
});
/* CSS goes here */
.is-eligible {
color: green;
}
.not-eligible {
color: red;
}

Thanks in advance
One way hard-coding this logic into the directive using option.text():
angular.element(option).addClass(option.text()); //
However, this would ignore the expression. http://plnkr.co/edit/46HndjYtg6HUbblnceNr?p=preview
Fix
app.directive('optionsClass', function ($parse) {
return {
require: 'select',
link: function(scope, elem, attrs, ngSelect) {
var optionsSourceStr = attrs.ngOptions.split(' ').pop(),
getOptionsClass = $parse(attrs.optionsClass);
scope.$watch(optionsSourceStr, function(items) {
var options = elem.find("option");
angular.forEach(items, function(item, index) {
var classes = getOptionsClass(item);
var option = options.eq(index);
angular.forEach(classes, function(add, className) {
if(add) {
angular.element(option).addClass(className);
}
});
});
});
}
};
});
