registry-min.js

一个struts和extjs得源码

Ext.dd.Registry=function(){var d={};var b={};var a=0;var c=function(f,e){if(typeof f=="string"){return f}var g=f.id;if(!g&&e!==false){g="extdd-"+(++a);f.id=g}return g};return{register:function(h,j){j=j||{};if(typeof h=="string"){h=document.getElementById(h)}j.ddel=h;d[c(h)]=j;if(j.isHandle!==false){b[j.ddel.id]=j}if(j.handles){var g=j.handles;for(var f=0,e=g.length;f<e;f++){b[c(g[f])]=j}}},unregister:function(h){var k=c(h,false);var j=d[k];if(j){delete d[k];if(j.handles){var g=j.handles;for(var f=0,e=g.length;f<e;f++){delete b[c(g[f],false)]}}}},getHandle:function(e){if(typeof e!="string"){e=e.id}return b[e]},getHandleFromEvent:function(g){var f=Ext.lib.Event.getTarget(g);return f?b[f.id]:null},getTarget:function(e){if(typeof e!="string"){e=e.id}return d[e]},getTargetFromEvent:function(g){var f=Ext.lib.Event.getTarget(g);return f?d[f.id]||b[f.id]:null}}}();
