cursor-position

I have a contentEditable HTML element. I would like to get the cursor's parent element. For example, if the cursor is inside a table cell, I would like to display some controls for editing the table. Is this possible? Or am I going to track all key and mousepresses? Example using parentNode : document.getElementById('editable').onclick = function () { alert(this.parentNode.id); } 来源： https://stackoverflow.com/questions/7770404/contenteditable-cursors-parent-element

I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose). Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here) Then, on the label's MouseUp event, I want it to either stay in its current position or return

I hava a listview like the following. The text in the TextView comes from a database. ------------------------- TextView Button ------------------------- When I click on the button, I want to show the text in the TextView of this row in a Toast. My question is the following: When I click on the button, I am showing the text of the row, which is selected by the cursor. I am not showing the text of the row where the button is. I know the problem is the mCursor variable. I don't know how to fix it. Has anybody an idea? Here is my ModulCursorAdapter: public class ModuleCursorAdapter extends

I am making a little word prediction plugin for tinyMCE and need to extract a bit of text and later insert text from a list of predicted words. The insertion should be no problem, as I know where the cursor is and can use the mceInsertContent command. Getting the text for the prediction however... I need to extract a subset of the text ending at the letter immediately before the cursor position and starting at, well, the start of the text. I can strip HTML tags myself if neccessary, but I prefer letting tinyMCE do it if possible. I was thinking of doing it like this: Insert bookmark at current

I found the following code here on SO to get the position of the cursor of a contenteditable div, however it always returns 0. The function that should retrieve the position: new function($) { $.fn.getCursorPosition = function() { var pos = 0; var input = $(this).get(0); // IE Support if (document.selection) { input.focus(); var sel = document.selection.createRange(); var selLen = document.selection.createRange().text.length; sel.moveStart('character', -input.value.length); pos = sel.text.length - selLen; } // Firefox support else if (input.selectionStart || input.selectionStart == '0') pos =

I cannot seem to get my image to display the coordinates of my mouse cursor, and also use ginput to store points at the same time. I currently am trying the following: MriHotrod = imread('Image.bmp'); Fig = figure('Name','BobDole'),... imshow(Image, 'InitialMagnification', 250) axis on impixelinfo Image_1 = ginput(4) close BobDole The ginput still works, but the impixelinfo stays constant Pixel Info = (X, Y) Pixel Value I am aware of some methods of getting around this, but they involve functions. This seems like a rather simple problem that can avoid the use of functions. If you type edit
