checkbox

问题 I have a list of variable length and want to create a checkbox (with python TKinter) for each entry in the list (each entry corresponds to a machine which should be turned on or off with the checkbox -> change the value in the dictionary). print enable {'ID1050': 0, 'ID1106': 0, 'ID1104': 0, 'ID1102': 0} (example, can be any length) now the relevant code: for machine in enable: l = Checkbutton(self.root, text=machine, variable=enable[machine]) l.pack() self.root.mainloop() This code produces

问题 I have tons of checkboxes that are either checked ( checked="checked" ) or unchecked. I would like to get the number of all checkboxes, unchecked and checked checkboxes. With check-box I mean <input type="checkbox" /> . How to do it with jQuery? Thanks in advance! 回答1: You could do: var numberOfChecked = $('input:checkbox:checked').length; var totalCheckboxes = $('input:checkbox').length; var numberNotChecked = totalCheckboxes - numberOfChecked; EDIT Or even simple var numberNotChecked = $(

问题 I have a problem with the following code in an ASPX page: <script type="text/javascript"> $(document).ready(function() { $('.test').click(function() { alert("click") }) }); </script> <asp:CheckBox runat="server" Text="Checkbox XYZ" CssClass="test" ID="cb1" /> In the browser (FF3.5 / IE8) I have the following problem: if I click the checkbox (the small square), it works as expected if I click the checkbox's text ("Checkbox XYZ"), then the click event is fired twice, and the alert is shown

问题 What would be the correct way of receiving and sending an event when a check box gets enabled or disabled? In C# I could just easily double click and all the code would be done for me. But in android it appears to be a bit more obscure. I thought of using the touch event handlers but then if the user has a keyboard it won't detect the change since it's not touch. I figure android should have a native event for check box state change. 回答1: CheckBox repeatChkBx = ( CheckBox ) findViewById( R.id

问题 I am looking for something exactly like these (tri-state checkboxes with "parents"). But using that solution wouldn't be elegant, as I do not depend on jQuery right now, and I would need to call $scope.$apply to get the model to recognize the automatically (un)checked checkboxed jQuery clicked. Here's a bug for angular.js that requests ng-indeterminate-value implemented. But that still wouldn't give me the synchronization to all the children, which is something I don't think should be a part

问题 Can any one tell me how can i obtain the values of the checked rows in a custom view list? For example my code has a custom view list with two text view and a checkbox.

The code is public class contacts extends Activity implements OnItemClickListener { static final String TAG = "contacts"; ArrayList<String> contactName = new ArrayList<String>(); ArrayList<String> contactNumber =

问题 I was looking for a a JTree implementation, that contains checkboxes and which: When you select one node, all its successors in the tree are automatically selected When you unselect one node, all its successors in the tree are automatically unselected When a parent node is already selected, and the selection was removed from one of its successors, the node color will be changed, to make it intuitive that although this parent node is selected, not all of its successors are selected (Like when
