selection

问题 I 'de like to higlight text selected by the user and copy it over to a text box. The latter part works great. But highlighting of the selected text fails if I try to highlight part of an already highlighted text. Here's a JSFiddle Try selecting the text on the right box, then try to select part of your previous selection. Any ideas? The relevant code: function highlightSelected() { var selection = getSelected(); var range = selection.getRangeAt(0); var newNode = document.createElement("span")

问题 I want a method to inquire, after changing the ActiveSheet ( EDIT: of any open Workbook ): Detect the type of Selection in the previous active sheet (of most importance, if it was a ChartObject or Range ). If it is a Range , get the address. Is this possible ...? EDIT : ... (cont.) Without additional Activating/Deactivating to inquire (preferred). With additional Activating/Deactivating to inquire. Note that adding code to ThisWorkbook only affects that Workbook. So, I guess that something

问题 I have a JavaFX TableView and a ListView and they both use custom cell factories. In particular I have overridden updateItem method in order to bind a particular CSS class based on cell value. This is part of my CSS file: .tissueCell { -fx-text-fill: #F5AD11; } .tissueCell:selected { -fx-background-color: #F5AD11; -fx-text-fill: white; } .significantDataCell { -fx-background-color: yellow; -fx-text-fill: black; } .significantDataCell:selected { -fx-background-color: white; -fx-text-fill:

问题 Currently I'm getting the selected button in this way, but I don't if this is the right/best method. MAybe there something more easy or object oriented than this. private int getFilterType(JRadioButton... buttons) { for (int i = 0, n = buttons.length; i < n; i++) { if (buttons[i].isSelected()) { return i + 1; } } return buttons.length + 1; } 回答1: I like using the ButtonGroup itself for this. i.e., import java.awt.GridLayout; import java.awt.event.ActionEvent; import javax.swing.*; public

问题 I want to monitor the selection of text into the a JTextArea. I don't know what event a selection of text triggers. I just want to enable some of the menu items as soon as some text is selected out of the JTextArea like copy and cut options into the menu. What should I monitor for that? 回答1: I don't know about any "selection listeners" for text components (although they might be useful), but you could use a CaretListener to monitor changes to the caret position and check the selection state..

问题 I have been struggling with this for a while now. I have a Master / Details layout in my application, and am faced, like many others, with the problem of the DataGrid loosing its selection when disabling it. Essencialy, after selecting an element from the list to populate a series of fields, the user presses "Edit", wich disables the DataGrid and enables all of the form's fields. Pressing the "Save" button will revert these actions after saving the data... Pretty strait forward. I am on

问题 I created a contentEditable div with a text portion and a link. Double clicking the link will select the link text. <div contentEditable="true"> This is a text and <a href="http://www.google.com">This_is_a_link</a> </div> Afterwards calling document.getSelection().getRangeAt(0).startContainer will return the div: // => <div contenteditable="true"> Instead of the link. I cannot find a way to find which part of the div is selected. See this jsfiddle (double click the "This_is_a_link" and there

问题 In programmatically defining a range/selection in JavaScript, is it not possible to have the focusOffset in the range be before the anchorOffset? How do we define a right to left selection then? a JS fiddler link for example: http://jsfiddle.net/johncch/ejVab/1/ 回答1: The way to create a "backwards" selection is slightly non-obvious. It can't be done by simply selecting a Range via the selection addRange() method because ranges are intrinsically directionless. You need to use the extend()

问题 I am faced with following: when I try to select text in a contenteditable element and the end of the selection is the start of the element content, then no select event is fired and there are no Selection and Range objects. Could somebody please give me any advice on why this might occur or how I can prevent this? Code responsible for getting selection range: $('div[contenteditable="true"]').bind("mouseup keyup touchend", function() { lastCaretIndex = getSelectionRange(); }); function
