I struggled with this problem for a while. What worked was to bind the input to an object instead of a primitive. <!– Partial –> <input type=”checkbox” ng-model=”someObject.someProperty”> Check Me! // Controller $scope.someObject.someProperty = false
jQuery UI autocomplete function automatically adds the class “ui-autocomplete-input” to the element. I’d recommend live binding the element on focus without the “ui-autocomplete-input” class to prevent re-binding on every keydown event within that element. $(“.foo:not(.ui-autocomplete-input)”).live(“focus”, function (event) { $(this).autocomplete(options); }); Edit My answer is now out of date since jQuery 1.7, see Nathan Strutz’s comment … Read more
You can do the binding in the constructor by using ES6: export default class Nav extends Component { constructor(props) { super(props); this.onPress = this.onPress.bind(this); } and then onPress(txt) { console.log(txt); } render() { return ( <View> <Text>####################</Text> <Text>Intro Screen</Text> <Text>Number: {this.props.numbers}</Text> <TouchableHighlight onPress={() => this.onPress(‘foo’)}> <Text>Go to Foo</Text> </TouchableHighlight> </View> ); } }
Perhaps the simplest solution is to make a global binding for the mousewheel. It will then fire no matter what widget is under the mouse or which widget has the keyboard focus. You can then unconditionally scroll the canvas, or you can be smart and figure out which of your windows should scroll. For example, … Read more
Scenario 1: <li ng-repeat=”item in ::items”>{{::item.name}}</li> Both expressions will be one-time bound. Adding an item or changing an existing item’s name will not be reflected. Demo: http://plnkr.co/edit/53r8FCmcNK4MmM6Uzxp2?p=preview Scenario 2: <li ng-repeat=”item in ::items”>{{item.name}}</li> First expression will be one-time bound. Adding an item will not be reflected. Changing an existing item’s name will be reflected. Demo: … Read more
<router-outlet></router-outlet> can’t be used to emit an event from the child component. One way to communicate between two components is to use a common service. Create a service shared-service.ts import { Observable } from “rxjs/Observable”; import { Injectable } from “@angular/core”; import { Subject } from “rxjs/Subject”; @Injectable() export class SharedService { // Observable string … Read more
If you start with Jason’s suggestion then the problem becomes a single bound selection from a list which translates very nicely to a ListBox. At that point it’s trivial to apply styling to a ListBox control so that it shows up as a RadioButton list. <ListBox ItemsSource=”{Binding …}” SelectedItem=”{Binding …}”> <ListBox.ItemContainerStyle> <Style TargetType=”{x:Type ListBoxItem}”> <Setter … Read more
let creates a lexically scoped immutable alias for some value. binding creates a dynamically scoped binding for some Var. Dynamic binding means that the code inside your binding form and any code which that code calls (even if not in the local lexical scope) will see the new binding. Given: user> (def ^:dynamic x 0) … Read more
You get an ExceptionInInitializerError if something goes wrong in the static initializer block. class C { static { // if something does wrong -> ExceptionInInitializerError } } Because static variables are initialized in static blocks there are a source of these errors too. An example: class C { static int v = D.foo(); } => … Read more
1) Before, you had to resort to manually parsing the date: public void webmethod(@RequestParam(“date”) String strDate) { Date date = … // manually parse the date } Now you can get the parsed date directly: public void webmethod(@RequestParam(“date”) Date date) { } 2) If your jsp page supplies a date on the form yyyy-MM-dd you … Read more
