angular-ngmodel

问题 I've been fighting with this for almost two days. I hope you guys can help me. Summary: I have problems setting the view value of some input fields programatically. I have a form with inputs whose values are saved before the form is removed (multiple elements and multiple forms possible, user might close a form, and reopen later). On reopening the form I want to restore the previous view values (main reason is to get back also the invalid view values which were not saved in the model). This

问题 What is the purpose of using forRoot in NgModule? Is it same as the providers in AngularJS 1.x? How does it play the significant role in lazy loading? TIA. 回答1: It has to do with singletons. Angular services are loaded onto the page 1 time (singleton) and all references point back to this 1 instance. There is a risk that a lazy loaded module will try to create a 2nd instance of what should be a singleton, and the forRoot() method is a way to ensure that the app module / shared module / and

问题 This question already has answers here : What's the difference/incompatibility between ng-model and ng-value? (5 answers) Closed 5 months ago . I was trying to give a value to textfield using ngvalue and textarea has that value but it when I submit it, it recognized as textarea is empty. <textarea ng-value="main.record.basic_info.application_letter" class="form-control" ng-model="main.record.apply_job.cover_letter" name="name" rows="15" cols="80" style="resize: none"> </textarea> 回答1: You

问题 I'm pretty new to Angular, so I may be going about this all wrong... I have a <select> similar to the following: <select ng-model="mySelectedValue"> <option value="">--</option> <option ng-repeat="myValue in someDynamicArrayOfValues" value="{{myValue}}" ng-selected="myFunctionForDeterminingWhetherValueIsSelected(myValue)">{{myValue}}</option> </select> This mostly works... The dropdown initially renders with the correct option selected, and if I change the selected option, then

问题 First and foremost, the plunker: http://plnkr.co/edit/v1uTz5 This is a working demo of the issue I am running into. I have a ng-include to include a partial. Inside the partial I have an text input with ngModel AND directive. The model updates accordingly inside the include, but any interaction outside the include is ignored. The {{test}} outside the include doesn't update, but the {{test}} inside does. The directive, when called, handles the enter key and calls the correct scope and function

问题 I'm new to angular2. I want to store user input from a text area in a variable in my component so I can apply some logic to this input. I tried ngModel but it doesn't work. My code for the textarea: <textarea cols="30" rows="4" [(ngModel)] = "str"></textarea> And inside my component: str: string; //some logic on str But I don't get any value in str inside my component. Is there an error with the way I'm using ngModule ? 回答1: <pre> <input type="text" #titleInput> <button type="submit" (click)

问题 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(

问题 I recently upgraded the angular version to 6-rc. I got following warning It looks like you're using ngModel on the same form field as formControlName. Support for using the ngModel input property and ngModelChange event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7 For more information on this, see our API docs here: https://angular.io/api/forms/FormControlName#use-with-ngmodel What does it say exactly? the link does not have any fragment
