我想为伪造查看器中的不同对象定义不同的上下文菜单,这是我的代码
viewer.addEventListener(Autodesk.Viewing.AGGREGATE_SELECTION_CHANGED_EVENT,function(e){
if(viewer.getSelection().length==0){return;}
var selectId=viewer.getSelection()[0];
viewer.search("Cabinet",function(ids){
if(ids.indexOf(selectId)!=-1){
viewer.registerContextMenuCallback('CabinetMsg', function (menu, status) {
if (status.hasSelected) {
menu.push({
title: "CabinetMsg",
target: function () {
openLayer('CabinetMsg','954','775','CabinetMsg.html')
}
});
}
});
}else{
viewer.registerContextMenuCallback('CabinetMsg', function (menu, status) {
if (status.hasSelected) {
menu.forEach(function(el,index){
if(el.title=="CabinetMsg"){
menu.splice(menu.indexOf(index),1)
}
})
}
});
}
})
});
但是推送元素到数组的时间总是比上下文菜单显示的要晚。当我选择另一个对象时,我的自定义上下文菜单总是显示。我能做什么?

您提供的代码将为上下文菜单创建2个新子项。这是这种情况的一种方式,即你必须自己编写<?php
class Upload extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
public function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
public function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
// get the user submitted file name here
if ( ! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
}
?>
。此外,您需要在ViewerObjectContextMenu
中执行hitTest
以通过鼠标右键单击选择dbId。以下是您的示例:
ViewerObjectContextMenu.buildMenu
在此之后,您可以编写一个扩展名,用您自己的菜单替换默认查看器上下文菜单。这也是一个例子:
class MyContextMenu extends Autodesk.Viewing.Extensions.ViewerObjectContextMenu {
constructor( viewer ) {
super( viewer );
}
isCabinet( dbId ) {
// Your logic for determining if selected element is cabinet or not.
return false;
}
buildMenu( event, status ) {
const menu = super.buildMenu( event, status );
const viewport = this.viewer.container.getBoundingClientRect();
const canvasX = event.clientX - viewport.left;
const canvasY = event.clientY - viewport.top;
const result = that.viewer.impl.hitTest(canvasX, canvasY, false);
if( !result || !result.dbId ) return menu;
if( status.hasSelected && this.isCabinet( result.dbId ) ) {
menu.push({
title: 'CabinetMsg',
target: function () {
openLayer( 'CabinetMsg', '954', '775', 'CabinetMsg.html' );
}
});
}
return menu;
}
}
希望得到这个帮助。
