Regardless of whether any text is selected, the SelectionStart property represents the index into the text where you caret sits. So you can use String.Insert to inject some text, like this: myTextBox.Text = myTextBox.Text.Insert(myTextBox.SelectionStart, “Hello world”);
IE use different approach at setting cursor position than Firefox,Opera and Chrome. It’s better to make a helper function, which will do it for you. I use this one for own needs. function setCursor(node,pos){ node = (typeof node == “string” || node instanceof String) ? document.getElementById(node) : node; if(!node){ return false; }else if(node.createTextRange){ var textRange … Read more
Maybe I’m misreading the question, but wouldn’t the following do (assuming an editable <div> with id “editable”)? The timer is there because in Chrome, the native browser behaviour that selects the whole element seems to trigger after the focus event, thereby overriding the effect of the selection code unless postponed until after the focus event: … Read more
Although I would not recommend changing the default cursor mechanics, one way of achieving the behavior in question is to use the following Insert-mode mapping. :inoremap <silent> <Esc> <Esc>`^ Here the Esc key is overloaded in Insert mode to additionally run the `^ command which moves the cursor to the position where it had been the … Read more
Using the console functions, you’d use SetConsoleCursorPosition. Without them (or at least not using them directly), you could use something like gotoxy in the ncurses library. Edit: a wrapper for it is pretty trivial: // Untested, but simple enough it should at least be close to reality… void gotoxy(int x, int y) { COORD pos … Read more
If all you want to do is insert some content at the cursor, there’s no need to find its position explicitly. The following function will insert a DOM node (element or text node) at the cursor position in all the mainstream desktop browsers: function insertNodeAtCursor(node) { var range, html; if (window.getSelection && window.getSelection().getRangeAt) { range … Read more
You can set the caret position using CaretIndex property of a TextBox. Please bear in mind that this is not a DependencyProperty. Nevertheless, you may still set it in XAML like this: <TextBox Text=”123″ CaretIndex=”{x:Static System:Int32.MaxValue}” /> Please remember to set CaretIndex after Text property or else it will not work. Thus it probably won’t … Read more
As @Hovercraft has pointed out. Start by looking at Robot#getPixelColor. You will need to know where the mouse cursor is, while there’s no “easy” way to track the cursor, you can get it’s current location using MouseInfo#getPointerInfo UPDATED with example This is little example of the concept. This works based on the moition of the … Read more
You can’t do this without some browser specific code, since they implement text select ranged slightly differently. However, there are plugins that abstract this away. For exactly what you’re after, there’s the jQuery Caret (jCaret) plugin. For your code to get the position you could do something like this: $(“#myTextInput”).bind(“keydown keypress mousemove”, function() { alert(“Current … Read more
Modified BojanG’s solution to work with jQuery. Tested in Chrome, FF, and IE. (function ($, undefined) { $.fn.getCursorPosition = function() { var el = $(this).get(0); var pos = 0; if(‘selectionStart’ in el) { pos = el.selectionStart; } else if(‘selection’ in document) { el.focus(); var Sel = document.selection.createRange(); var SelLength = document.selection.createRange().text.length; Sel.moveStart(‘character’, -el.value.length); pos = … Read more
