The difference is especially noticeable if we drag the ball by its right-bottom corner. On the beginning of the drag’n’drop, the ball “forks”: we start dragging its “clone”. If we run the code, we can notice something strange. (3) drop the ball, remove unneeded handlersĭocument.removeEventListener('mousemove', onMouseMove) move our absolutely positioned ball under the pointerĭocument.addEventListener('mousemove', onMouseMove) centers the ball at (pageX, pageY) coordinatesī = pageX - ball.offsetWidth / 2 + 'px' ī = pageY - ball.offsetHeight / 2 + 'px' to make it positioned relative to the body move it out of any current parents directly into body (1) prepare to moving: make absolute and on top by z-index Here’s the implementation of dragging a ball: Later we’ll see how to add other features, such as highlighting current underlying elements while we drag over them. On mouseup – perform all actions related to finishing the drag’n’drop.Then on mousemove move it by changing left/top with position:absolute.On mousedown – prepare the element for moving, if needed (maybe create a clone of it, add a class to it or whatever).The basic Drag’n’Drop algorithm looks like this: So here we’ll see how to implement Drag’n’Drop using mouse events. Also, mobile device support for such events is very weak. And there are many other drag’n’drop tasks that can’t be done using them. Also we can’t make the dragging “horizontal” or “vertical” only. For instance, we can’t prevent dragging from a certain area. Then JavaScript can access the contents of such files.īut native Drag Events also have limitations. These events allow us to support special kinds of drag’n’drop, such as handling dragging a file from OS file-manager and dropping it into the browser window. In the modern HTML standard there’s a section about Drag and Drop with special events such as dragstart, dragend, and so on. Taking something and dragging and dropping it is a clear and simple way to do many things, from copying and moving documents (as in file managers) to ordering (dropping items into a cart). Using the fill handle makes data entry easier as well as makes your Excel operations more efficient.Drag’n’Drop is a great interface solution.

If you use the fill handle like before, it will just add the next dates in adjacent cells. Suppose you have entered the date and you want to use the fill handle to get only weekdays. Selecting B7 and B8 will help Excel recognize the pattern and correctly fill the subsequent cells. Selecting the entire range and then using the fill handle will fill the new cells in sequential order. Just selecting the last cell will fill only that value in the cells where you drag the fill handle in Excel.įor example, if we drag the fill handle after only selecting cell B8, the entire range is filled only with the value “1002”. It can even be that you have not selected the entire range that has your sequential values. Once you have enabled this, you can easily use Excel Fill handle feature! STEP 3:In the Advanced category, under Editing options, select the Enable fill handle and cell drag-and-drop check box. STEP 2: Click Options from the menu on the left side If you are unable to use this function, you can simply fix it using the steps below: Let’s see how you can overcome these problems. If you are unable to use this function or the filled values are not as per your pattern, you can easily fix it. STEP 4: After using the Excel fill handle, your values will be filled, like so! STEP 3: Go to the bottom right of your selection, you can drag the fill handle Excel to copy data or to fill adjacent cells with a series of data. STEP 2: Select the cells in which you have entered the values. STEP 1: Enter the starting values of your sequence in a range of cells. You can easily learn how to use fill handle in Excel by following the steps below: So using the fill handle, you can fill all the cells below with values that follow in the series, like 4,5,6…. This is known as a fill handle Excel and it can fill adjoining cells with subsequent data following a certain pattern.įor example, cells A1, A2, and A3 have the values 1,2, and 3. In Excel, you are equipped with a tool that can help you fill values in neighboring cells.
