我知道这里有很多类似的问题，但是，当把它们付诸行动时，我仍然解决了同样的问题。
我有 2 个角度指令（拖放）和一个角度工厂（dndAPI）。这一切都基于fisshy 在 github 上的 Angular Drag and Drop。
我终于让 Firefox 通过向事件添加数据来接受和拖动移动，但是我似乎无法阻止它执行默认行为（并将该数据加载为 url）。我也很抱歉，我根本无法让它在 jsfiddle 上工作......根本。如果有人看不出我是否做错了什么，我会再试一次。
angular.module('dragAndDrop', [])
.directive('drag',function (dndApi) {
var drags = [],
dragging = new RegExp('(\\s|^)dragging(\\s|$)');
return {
restrict: 'A',
scope: {
item: '=drag',
whenStart: '&',
whenEnd: '&',
dropzones: '='
},
link: function (scope, elem, attr, ctrl) {
elem.bind('dragstart', function (e) {
angular.element('query-tool-tip').removeClass('active');
//if ( drags.length === 0 ) {
drags = document.querySelectorAll('.drop');
//}
angular.forEach(drags, function (value, key) {
if (scope.dropzones.indexOf(value.getAttribute('drop')) >= 0) {
value.className = value.className + ' dragging';
}
});
elem.addClass('dragging');
dndApi.setData(scope.item, scope.dropzones);
e.originalEvent.dataTransfer.effectAllowed = 'move';
//KEEPS FIREFOX FROM CRAPPING OUT:
e.originalEvent.dataTransfer.setData( 'text/plain', 'stop' );
scope.$apply(function () {
scope.whenStart({ data: dndApi.getData() });
});
});
elem.bind('dragleave', function(e){});
elem.bind('dragend', function (e) {
elem.removeClass('dragging');
angular.forEach(drags, function (value, key) {
value.className = value.className.replace(dragging, '');
});
scope.$apply(function () {
scope.whenEnd({ data: dndApi.getData() });
});
dndApi.removeData();
e.preventDefault();
});
elem[0].draggable = true;
elem[0].className = elem[0].className + ' drag';
}
};
}).directive('drop',function (dndApi) {
var drags = [],
dragging = new RegExp('(\\s|^)dragging(\\s|$)');
return {
scope: {
drop: '=drop',
whenDrop: '&',
whenEnter: '&',
whenLeave: '&',
queryIndex: "=queryIndex",
hideElem: '='
},
link: function (scope, elem, attr, ctrl) {
var left = elem[0].offsetLeft,
right = left + elem[0].offsetWidth,
top = elem[0].offsetTop,
bottom = top + elem[0].offsetHeight;
elem.bind('drop', function (e) {
// e.originalEvent.preventDefault();
//if (e.stopPropagation()) {
// e.stopPropagation();
//e.originalEvent.stopPropagation();
//e.preventDefault();
//e.originalEvent.preventDefault();
//}
e.originalEvent.dataTransfer.clearData();
if (dndApi.getDropZones().indexOf(scope.drop) >= 0) {
scope.$apply(function () {
scope.whenDrop({ data: dndApi.getData(), queryI: scope.queryIndex });
});
}
if (drags.length === 0) {
drags = document.querySelectorAll('.drop');
}
angular.forEach(drags, function (value, key) {
value.className = value.className.replace(dragging, '');
});
dndApi.removeData();
e.stopPropagation();
e.originalEvent.stopPropagation();
e.preventDefault();
e.originalEvent.preventDefault();
});
elem.bind('dragenter', function (e) {
e.preventDefault();
e.originalEvent.preventDefault();
if (elem[0] == e.target) {
scope.$apply(function () {
scope.whenEnter({ data: dndApi.getData() });
});
}
return false;
});
elem.bind('dragleave', function (e) {
e.preventDefault();
e.originalEvent.preventDefault();
if ((e.x < left || e.x > right) ||
(e.y < top || e.y > bottom)) {
scope.$apply(function () {
scope.whenLeave({ data: dndApi.getData() });
});
}
return false;
});
elem.bind('dragover', function (e) {
//if (e.preventDefault) {
e.preventDefault();
e.originalEvent.preventDefault();
//}
return false;
});
elem[0].className = elem[0].className + ' drop';
scope.$watch('hideElem', function () {
if (scope.hideElem === true) {
elem.hide();
} else {
elem.show();
}
});
}
};
}).factory('dndApi', function () {
var dnd = {
dragObject: {},
dropzones: []
};
return {
setData: function (data, areas) {
dnd.dragObject = data;
dnd.dropzones = areas;
},
removeData: function () {
dnd.dragObject = null;
dnd.dropZones = [];
},
getData: function () {
return dnd.dragObject;
},
getDropZones: function () {
return dnd.dropzones;
}
};
});
我已经做了很多关于其他问题的建议。我已将 event.preventDefault() 添加到 dragenter 和 dragleave 点。然后当这不起作用时，我将它们添加到任何地方。我觉得这与我的 drop 方法有关。如果我将 event.prevendDefault() 放在绑定的开头，则不会执行其余代码。
任何建议，即使是我可能忽略的小事，都会有所帮助。
谢谢！
