jQuery + Flex 通过拖拽方式动态改变图片的代码

代码如下：

1. function init() {
   
2. if(swfobject.hasFlashPlayerVersion("10")){
   
3. var flashvars = {};
   
4. flashvars.xmlPath = "coffee";
   
5. flashvars.name = "coffee";
   
6. var params = {};
   
7. params.quality = "high";
   
8. params.wmode = "transparent";
   
9. var attributes = {};
   
10. attributes.id = "swf_editer";
    
11. swfobject.embedSWF("../img/swf/PhotoEditer2.swf","editarea","670","690","10.3"
    
12. ,"../img/swf/playerProductInstall.swf",flashvars,params,attributes);
    
13. $( ".draggable" ).draggable({ revert: true, helper: "clone" });
    
14. $("body").bind("mousemove",getListener);
    
15. }
    
16. }
    
17. var srcName = "";
    
18. var currentX = 0;
    
19. var currentY = 0;
    
20. var currentTop = 0;
    
21. function setImgLocal(srcName) {
    
22. bindDroppable();
    
23. this.srcName = srcName ;
    
24. }
    
25. function changeSwfImg() {
    
26. if(srcName === "" || srcName === null){
    
27. return ;
    
28. }
    
29. var swf = swfobject.getObjectById("swf_editer");
    
30. var swfCoord = getSwfCoord();
    
31. var dom = {};
    
32. dom.name = srcName;
    
33. dom.changeFlg = 0;
    
34. //*********************************
    
35. var tmp1 = swfCoord.domY - 0;
    
36. tmp2 = swfCoord.domHeight - 220;
    
37. //*********************************
    
38. if((currentTop + currentY) > (swfCoord.domY + 100)
    
39. && (currentTop + currentY) < (tmp1 + tmp2))
    
40. {
    
41. dom.changeFlg = currentX - swfCoord.domX < swfCoord.domWidth/2 ? 1 : 2;
    
42. }
    
43. swf.FlexManager(dom);
    
44. }
    
45. function bindDroppable() {
    
46. $("#swf_editer").droppable({
    
47. accept: "#dv_draggables img",
    
48. drop: function(event, ui) {
    
49. changeSwfImg();
    
50. }
    
51. });
    
52. }
    
53. function getListener(event) {
    
54. currentX = event.clientX;
    
55. currentY = event.clientY;
    
56. currentTop = document.documentElement.scrollTop ;
    
57. }
    
58. function getSwfCoord() {
    
59. var swf = swfobject.getObjectById("swf_editer");
    
60. var dom = {};
    
61. dom.domX = 0 , dom.domY = 0;
    
62. dom.domWidth = swf.width;
    
63. dom.domHeight = swf.height;
    
64. while(swf.offsetParent) {
    
65. dom.domX += swf.offsetLeft;
    
66. dom.domY += swf.offsetTop;
    
67. swf = swf.offsetParent;
    
68. }
    
69. return dom;
    
70. }
