I am trying to find to get the checkbox value if it is checked using Blazor framework, but I couldn't find any method for it so far. When I put the binding in the checkbox, it is always checked. I couldn't figured it out how to get the checked value.
This is my code:
<input type="checkbox" id="addition" name="math" value="add" bind="@name" /> <label for="addition">Addition</label>
If a checkbox is marked or checked, it indicates to true; this means that the user has selected the value. If a checkbox is unmarked or not checked, it indicated to false; this means that the user has not selected the value.
To get the state of a checkbox, you follow these steps: First, select the checkbox using a DOM method such as getElementById() or querySelector() . Then, access the checked property of the checkbox element. If its checked property is true , then the checkbox is checked; otherwise, it is not.
You can check/uncheck the checkbox in the Blazor programmatically by using the @bind parameter in the checkbox. Assign a Boolean property to @bind in the checkbox and toggle the Boolean property programmatically.
Build A Paint Program With TKinter and Python To print the value of the selected checkbox, we can use the get() method. It returns the input value of a particular widget.
@page "/registration" @foreach (var club in ClubList()) { <input type="checkbox" @onchange="eventArgs => { CheckboxClicked(club, eventArgs.Value); }" />@club<br /> } @functions { public List<string> ClubMember { get; set; } = new List<string>(); void CheckboxClicked(string clubID, object checkedValue) { if ((bool)checkedValue) { if (!ClubMember.Contains(clubID)) { ClubMember.Add(clubID); } } else { if (ClubMember.Contains(clubID)) { ClubMember.Remove(clubID); } } } public List<String> ClubList() { // fetch from API or... List<String> c = new List<String>(); c.Add("Clube01"); c.Add("Clube02"); return c; } }
