本文实例介绍了angularjs创建弹出框实现拖动效果的相关代码，项目中需要将angular-ui-bootstrap中用到的弹出框，使之可拖动，分享给大家供大家参考，具体内容如下。
由于源文件中没有实现，需要自己实现指令，以下即为该指令，亲测可以实现。
.directive('draggable', ['$document', function($document) { return function(scope, element, attr) { var startx = 0, starty = 0, x = 0, y = 0; element= angular.element(document.getelementsbyclassname(modal-dialog)); element.css({ position: 'relative', cursor: 'move' }); element.on('mousedown', function(event) { // prevent default dragging of selected content event.preventdefault(); startx = event.pagex - x; starty = event.pagey - y; $document.on('mousemove', mousemove); $document.on('mouseup', mouseup); }); function mousemove(event) { y = event.pagey - starty; x = event.pagex - startx; element.css({ top: y + 'px', left: x + 'px' }); } function mouseup() { $document.off('mousemove', mousemove); $document.off('mouseup', mouseup); } }; }]);
