我是EXT的新手,我在重新加载EXT 4树时遇到问题。我一直在尝试:
Ext.tree.getLoader().load(tree.root);
Ext.tree.load(tree.root);
Ext.tree.getRootNode().reload();
Ext.tree.TreePanel.root.reload();
Ext.data.TreeStore.reload();
没有任何帮助,我希望有人可以向我澄清这一点,这里是代码: 编辑:我已经添加了完整的代码,因为你可以看到所有内容都在extOnReady方法中,我在var树之前删除了var但仍然得到了相同的结果
Ext.QuickTips.init();
var store = Ext.create('Ext.data.TreeStore',{
proxy: {
type: 'ajax',
url: 'url1'
},
root: {
text: 'TOPP',
id: '1',
expanded: true
},
folderSort: true,
sorters: [{
property: 'text',
direction: 'ASC'
}]
});
tree = Ext.create('Ext.tree.Panel',{
id:'company_tree',
store: store,
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop'
}
},
renderTo: 'tree-div',
height: 300,
width: 766,
title: gettext('Companies'),
useArrows: true,
dockedItems: [{
xtype: 'toolbar',
items: [ {
text: gettext('Collapse All'),
handler: function(){
tree.collapseAll();
}
}]
}]
});
var loadingMask = new Ext.LoadMask(Ext.get('tree-div'),{
msg: gettext("Loading...")
});
tree.on('itemmove', function(tree, oldParent, newParent, index, options){
if(confirm(gettext('Are you sure you want to move this company?'))){
loadingMask.show();
Ext.Ajax.request({
scope: this,
url: 'url2/',
success:function(){
loadingMask.hide();
},
params: {
'ajaxAction[moveNode]': '',
index: index,
nodeid: tree.data.id,
parentNodeID: newParent.data.id,
oldParentNodeID: oldParent.data.id
}
});
}else{
Ext.getCmp('company_tree').getStore.load();
}
});
我也尝试通过控制台重新加载[Ext.getCmp('company_tree')。getStore.load();]并且它有效。当我通过代码尝试它时,它会返回关于fly函数的错误
n is null
[Break On This Error]
Ext.fly(n.firstChild ? n.firstChild : n).highlight(me.dropHighlightColor);
