checkbox

问题 I have the following code where i'm trying to filter on the players in the array by checking a checkbox for the pantsize of a player. I know i have the data array in a repeater, and then the filtering inputs in an element outside of the data array element (two different divs), could this be what's causing the disconnect? Because i notice when i add the checkbox to the repeater element i do get some form of feedback array when i click the checkbox. Binding a search input box was so easy to

问题 In my cms I have a checkbox group for categories. I would like to have a text input below that where the user can input the name of a new category and it will dynamically add a new checkbox with the provided name used for both the value and the label.

问题 I have an HTML form: <form action='process.php' method='post'> <input type='checkbox' name='check_box_1' /> Check me!<br> </form> Here is a section from the PHP script process.php : echo (isset($_POST['check_box_1']))?'Set':'Not set'; The output of the script when the checkbox is set is Set But when the checkbox is not set, the output is: Not set Why is this? This seems like a very poor design because my PHP script checks a number of $_POST variables to make sure they were passed along to the

问题 While it is trivial to store a checkbox's checked state in a variable using the checkbox's Click event, how would I do it via databinding? All the examples I have found have the UI updated from some datasource, or bind one control to another; I want to update a member variable when the checkbox is clicked. TIA for any pointers... 回答1: You need a dependency property for this: public BindingList<User> Users { get { return (BindingList<User>)GetValue(UsersProperty); } set { SetValue

问题 Is there any function or ng- something to check if any of the displayed Checkboxes are checked? I have the values through the ng-click="function()" and pass the values through. I can go by foot and check my array if any value is inside. I want to activate/deactivate the "next"-button if any Checkbox is checked.
