checkbox

问题 I am working on a school project where a user can choose what items he/she can borrow from the school's computer services office. I have completed the application form where the student/faculty can insert their profile information. I am having issues regarding the checkboxes in AngularJS. I need to total/sum up the IDs of the checkboxes so that it can be inserted into the database as a single int, not an array. Here are the code and some information. $scope.chkItems = [ { id: 1, name: 'Laptop

问题 I have an application with several item controls (treeviews and others) which contain an item template with a checkbox inside. This checkbox checked state is bound to an IsChecked property of the item view model. This works correctly when clicking on the checkbox, but it's impossible to check/uncheck them with the keyboard (I believe this is due to the fact that the checkbox itself never gets the focus). I like the solution proposed by DLeh in here: https://stackoverflow.com/a/24327765/352826

问题 I have multiple checkbox values as shown in figure: I know that can store values for single checkbox in DB but situation here is slightly different, so how could I successfully store them in different rows for the same DB.

问题 I have the following php code for submitting the form to the database the only problem is with the checkboxes ... on submitting the form this shows up Warning: join() [function.join]: Invalid arguments passed in /srv/disk6/1662822/www/website.co.nf/connect-mysql.php on line 16 <?php $host="host.com" ; $username="1662822_db1" ; $password="awesomepassword" ; $db_name="1662822_db1" ; $tbl_name="courses" ; $dbcon = mysqli_connect("$host","$username","$password","$db_name") ; if (!$dbcon) { die(

问题 I'm trying to create an AlertDialog to show an introduction message in my application, with a "Don't show this again" CheckBox below it. It works well when the message of the AlertDialog is short, but when is too long (requiring scrolling) the CheckBox is no longer shown. It gets "pushed out" by the TextView. The XML for the custom view (dont_show_again.xml): <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width=

问题 Using Play 2.3.x I am trying to understand how checkboxes are handled in forms. This question seems like an outdated solution for an older version of Play. I understand that checkbox info will only be posted if checked, but I've created a small sample app and no info is posted even if I check the boxes. Here is my sample "Hello World" application Model public static class Hello { @Required public String name; @Required @Min(1) @Max(100) public Integer repeat; public String color; public

问题 I'm trying to style a checkbox in a ReactJS environment for IE11, but don't seem to be having much success. Can anyone please advise? The code is as follows: CSS: .squared { input[type=checkbox] { border-radius: 4px; background: #ff0000; width:100px; } HTML: <Col numCol={2} className="col-w-select squared"> <input style={{float: 'left', borderColor: 'red', border: '3px'}} type="checkbox" checked={isChecked} /> <span className={(String(currentlyClicked) !== String(item[idField])) ? 'l-collapse

问题 I am trying to validate two checkboxes. One of them must be checked in order for the form to be valid. I would like to use a CustomValidator control, and validate on the server. (This .ascx page is a form that is displayed on a different .aspx page.) First I put in the checkboxes and a CustomValidator control on my .ascx page. Like this: <tr> <td colspan="3"> <input type="checkbox" runat="server" name="EmailCourse" class="" id="EmailCourse" value="" /> Email course <asp:CustomValidator id=

问题 I have a problem. I have a TTreeview descendant that shows checkboxes just fine on my own computer and all other I have tested myself. TVS_CHECKBOXES is set using SetWindowLong . In the Loaded method I set/maintain checked states with StateIndex := 2; , Item.State := TVIS_CHECKED , etc. So far so good. But now a person contacted me where the treeview checkboxes does not show at all on his WindowsXP SP3. (He even provided me with a screenshot.) From the program behavior, I can say the default

问题 Once upon a time this was working but somehow it's broken. I want to be able to produce checkboxes using ng-repeat to get as many checkboxes as required based on stored data and use these to filter through a table produced. Additionally I don't want identical values for the checkboxes to be repeated. I have made a plnkr with the code. <div class="row"> <label data-ng-repeat="x in projects"> <input type="checkbox" data-ng-true-value="{{x.b}}" data-ng-false-value='' ng-model="quer[queryBy]" />
