我有两个dijit.Trees:srcTree和trgTree。 我已经实现了trgTree.itemCreator函数,并且在目标节点/树中正确创建了被删除的节点,但是没有创建被删除节点的子节点。我已经尝试了许多排列来创建它们,但似乎没有任何效果。
对我所缺少的内容有任何见解。这是我的itemCreator代码:
trgTreeItemCreator: function(/*DomNode[]*/ nodes, target, /*dojo.dnd.Source*/ source) {
console.info("*** start newTreeItemCreator");
var tmp = dijit.getEnclosingWidget(nodes[0]);
var kids = dojo.map(tmp.item.items, function(kid){
return {
"id": kid.id,
"name": [kid.name[0]],
"type": [kid.type[0]]
};
});
var newItems = [{id:nodes[0].id, name:[tmp.label], type:[tmp.item.type[0]], items:kids}];
return newItems;
},
答案 0 :(得分:2)
我的帖子赢得了风滚草......真棒! :) 我想出了一个解决方法,就在这里。
var that = this;
this.trgTree =
new dijit.Tree({
model: this.trgTreeModel,
dndController: "dijit.tree.dndSource",
checkAcceptance: this.treeCheckAcceptance,
checkItemAcceptance: this.trgTreeCheckItemAcceptance,
getIconClass: app.getIcon,
onDndDrop: function(source, nodes, copy) {
that.handleDrop(that, dijit.getEnclosingWidget(
nodes[0]).item, this.current.item);
that.srcStore.save();
that.trgStore.save();
}
}, "trgTree");
handleDrop: function(inPage, inSrcItem, inTrgItem) {
console.info("*** start addItem: srcItem: " + inSrcItem.name[0]);
var srcType = inSrcItem.type[0];
var kids = inSrcItem.items;
if (inTrgItem.type != "fooType") {
// do something unique for fooType node targets
}
// add the item to the tree
inPage.addItem(inPage, inSrcItem, inTrgItem);
}
addItem: function(inPage, inSrcItem, inTrgItem) {
var srcType = inSrcItem.type[0];
var trgType = inTrgItem.type[0];
var theName = inSrcItem.name[0];
if (srcType == "fooType") {
srcType = inSrcItem.txType[0];
}
var newItem = {
id: inSrcItem.id[0],
name: theName,
type: srcType,
items: []
};
newItem = inPage.trgStore.newItem(newItem);
inPage.trgTreeModel.pasteItem(newItem, null, inTrgItem, false, 0);
var kids = inSrcItem.items;
if (kids !== undefined) {
// call recursively to add child items
for (var i in kids) {
inPage.addItem(inPage, kids[i], newItem);
// TODO: expand the node after it is added
}
}
},
所有这些代码都是在单个类中的上下文,其中这是该类(这是一个WaveMaker项目,因此该类是一个wm.Page)。 很抱歉缺乏详细信息和文档,但它是很好的入门代码。如果您对我的解决方法有具体问题,请询问,我会尝试及时回答。
