问题 I am writing a simple script for a Google Sheet. I have a button labeled "New Entry" (the button is actually a drawing with my script assigned to it). When the user clicks the button, the script inserts an empty row at a specified location and activates the first column so that the user can begin typing. Everything works great except that after the script finishes, the keyboard doesn't work until after the user manually clicks in the sheet. The correct cell is visibly activated, but I suspect

问题 I have a JTable with multiple rows and every row is presented via Point on a scatter plot. What I have to do is when a given point is selected on the scatter plot I have to associate this selection with selecting of the corresponding row in the JTable.

问题 I'm setting the selection background color via CSS: ::selection { background:#cc0000; color:#fff; } ::-moz-selection { background:#cc0000; color:#fff; } On most browsers when the focus is somewhere else (like an IFrame), the selection color will stay the same, e.g.: but on Firefox it won't: You can see this in action on jsFiddle here. How can I get Firefox to set the selection color in this case? Is this a bug? 回答1: How can I get Firefox to set the selection color in this case? Unfortunately,

问题 So my question is this. I have a table and I am hiding/showing rows based on a dropdown menu selection. What would like to have is the 2 menus working together rather than independently. If I select an item in the first dropdown, I would like to be able then to filter that item further with the second dropdown and so on with any additional dropdown. Here's the code I'm using that works independently currently. <script> $(document).ready(function(){ $('select#age').bind('change',function(){ if

问题 I'm having some problems changing polygon styles when selecting and deselecting polygons in a Leaflet Shiny app I'm working on. In my current app, when you click on a polygon, that polygon is highlighted with a different color. Ideally, I want the user to be able to select and highlight multiple polygons. I also want the user to be able to re-click a single highlighted polygon to deselect it. The best that I've been able to manage is to select multiple polygons, give them the same group ID

问题 I have a Jtable on which I called the method table1.setAutoCreateRowSorter(true); . So this works on well. But I also have a methos in my JFrame class which is fired when i push a button. It gets the selected rows indexes using this code int selectedRows[] = this.table1.getSelectedRows(); . And displays an edit window for the first row corresponding in the selected interval. The problem is that if I don't click on column's headers (I mean i don't sorte them at all) my method works perfect.

问题 I am working on a simple Firefox Extension and I want to get the selected text.
