multi-select

问题 I am building up angular 6 application, in which i am in the need to make a multi select dropdown using <input> text box without using <select> . Html : <form> Select User: <input type="text" name="user" [value]="users"><br> <button type="submit"> Submit </button> </form> Ts : import { Component } from '@angular/core'; @Component({ selector: 'my-app', templateUrl: './app.component.html', styleUrls: [ './app.component.css' ] }) export class AppComponent { users = ['First User', 'Second User',

问题 OK I have a weird one here. What I am trying to figure out is how to have one listview, populated by an ObservableCollection, update another ListView, populated by another ObservableCollection, based on the first listview's selection and then use a valueconverter to check or uncheck a checkbox based on the selection combined with the current item in the second listview. This part I somewhat have working by using multibinding, but the part that has me stumped is when I check or uncheck an item

问题 Heres the situation: I have a Category model, which needs to have an attribute where the user can select multiple items from 3-4 predefined values (meaning only I can add more, the admins can't, so there is no separate model for those 3-4 options). Enum would be great but with that, only 1 option can be selected. Since I am using Postgres, I am thinking about using an array type attribute to store the selected values. Is there a simpler, more efficient way to do this or another field type

问题 Edit:I think I have confused you guys with what I need. If I select val1 I need the function to return val1. If I then select val2, with val1 still selected as part of the multi select, I need to return val2. Then I can use the values to set the id and name of rewly created inputs. I have a select list that has multiple="multiple" I want to create a text input associated with each selected option and set the id and name of the new input based on the value of each newly selected option, but I

问题 Im using a multi-select ListView in C# .NET 4.5 The issue occurs when selecting multiple items (ie. Shift + End or Shift + Click, etc.) These are just a few examples of many different mouse/keyboard combinations for multi-selecting of course.. This is my event handler for when selecting items in a list: private void lvTitles_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e) { MessageBox.Show(e.Item.Text.ToString()); //MessageBox just for testing I am actually

问题 I am writing a small script which will set focus to the filter text input field of the multi select jquery widget. Based on the documentation, I can subscribe to the click event of the widget like this: // bind to event $("#multiselect").bind("multiselectopen", function(event, ui){ // event handler here }); So I tried this: $("#MyStatusWidget").bind("multiselectopen", function(event, ui){ // event handler here $(this).$(".ui-multiselect-filter").contents('input :text').focus()); }); Here is a

问题 I am using this plugin http://dotansimha.github.io/angularjs-dropdown-multiselect/#/ If you check the demo part in this page, please use the ' Smart Button Text ' Demo as i am using that. In this demo, if you select any users, those names will be displayed in the bar. Now, i want to give default value to it. So as soon as the page loads, there will be a default value present in this multiselect dropdown. In normal case, i can use ng-init. What should i do in this case ? Can someone shed some

问题 I'm developing a form with a number of multiselects. I use Select2 library for that. $(".chosen-select").select2({ allow_single_deselect: true, width: "150px" }); ...... <select id="ship2" class="chosen-select" data-placeholder="Select vessel"> <option></option> <option value="value1">title1</option> <option value="value2">title2</option> </select> The problem is that when I try to get selected values they are returned in the order they are specified in <select> element, not the order they

问题 I have two listboxes and am trying to add items from List 1 to List 2, and then be able to remove multiple items from List 2 at once. Note that List 1 stays stagnant (this is how it is supposed to be). I have the adding items working right: 'Add the selected items to List 2 Dim i As Integer If lst1.ItemsSelected.Count > 0 Then i = 0 While i < lst1.ListCount If lst1.Selected(i) Then lst2.AddItem (lst1.ItemData(i) & ";" & lst1.Column(1, i) & ";") lst1.Selected(i) = False End If i = i + 1 Wend
