阅读更多关于 get src from draggable img

问题 i have this little code to drag & drop images: $("img").draggable({ revert: true, opacity: 0.7, cursor: "move", cursorAt: { cursor: "crosshair", top: -5, left: -5 } }); $('#mybox').droppable({ drop: function () { $(this).append('<div style="float:left;"><img src="http://dummyimage.com/42x40/000/fff.jpg"></div>'); } }); the idea is: when I drag a image, instead of show the dummy image, show the image itself, but how i can get the src from image from draggable.

Constrain dragging to local axis of object

阅读更多关于 Constrain dragging to local axis of object

问题 I'm trying to implement something very similar to what 3D modeling programs do, when dragging an object along a local axis. The main difference is, that you don't move the cursor around the screen, instead you freely move the camera and the cursor is always in the middle of the screen. Kind of like a first person game. Imagine pointing the camera at the face of the cube below, marked with a blue cross (the cursor). You press and hold the mouse to "grab" the cube. The dragging of the cube

Flex: Why are TileList images disappearing on drag?

阅读更多关于 Flex: Why are TileList images disappearing on drag?

问题 I'm developing a Flex Air (desktop) application that loads images from the local filesystem into a TileList. The user will then be able to drag (copy) these images out of the list onto another control. I've finally got the images showing up correctly (and not disappearing after scrolling the TileList) but they seem to disappear from the TileList at the start of a drag operation. I come from a .NET background and am just learning AS3/Flex, so if you see me using any anti-patterns here, feel

问题 I have been fooling around with dragging and dropping controls in a grid panel in delphi 2010. Move a panel/button/whateever the contents are from one cell to another cell. Replacing existing or swapping places.

So I nested my Calculator elements in this -Tag and implemented some Drag&Drop-logic (which is mainly from a tutorial). Still it doesn't work.

问题 Is there any way to get the index of a dragged point in JQPlot? I want to change the pointLabel value when the point have moved. I know that JQPlot do it itself but only with integer. Or I work with decimal values. I'm trying this: $("#tooltip2").bind('jqplotDragStop', function (seriesIndex, pointIndex, pixelposition, data) { $(this).find('.jqplot-series-1.jqplot-point-'+pointIndex) .html(''+Math.round(pixelposition.yaxis * 10) / 10); }); But none of the parameters give me the current point
