I use google MATERIAL COMPONENTS FOR THE WEB and have problems with the "Simple Menu". Check my codepen: [Multiple menus per page?][1]
[1]: https://codepen.io/QJan84/pen/govRmg
The first menu works, the others do not.
What do I have to do to have multiple menus per page?
You’re using document.querySelector for menu and toggle, but it will return only the first node elements matching “.mdc-simple-menu” and “.js--toggle-dropdown” respectively.
Instead, you should use document.querySelectorAll that will return the NodeList, which you’ll need to convert to array to iterate with its elements.
I wrapped your example menus and toggles into containers for selecting toggles easier with Node.parentElement.
So, the final result might look like this:
const menuEls = Array.from(document.querySelectorAll('.mdc-simple-menu'));
menuEls.forEach((menuEl) => {
// Initialize MDCSimpleMenu on each ".mdc-simple-menu"
const menu = new mdc.menu.MDCSimpleMenu(menuEl);
// We wrapped menu and toggle into containers for easier selecting the toggles
const dropdownToggle = menuEl.parentElement.querySelector('.js--dropdown-toggle');
dropdownToggle.addEventListener('click', () => {
menu.open = !menu.open;
});
});

I'm trying to implement svg.js to make a map of a clickable floorplan.
But I cannot make this work properly, or this works but doesn't work like I expected:
const map = SVG.get('mysvg');
map.click(function( event ) {
this.fill({ color: '#000' });
console.log(this);
console.log(event.target);
});
When I try to click on some area on the map, instead of change fill color I get nothing.
Actually svgjs triggers 'create' as you can see in console with inspector.
Not sure what am I doing wrong here?
I would expect that the area will change fill color?

You can use the select function as described here to create a Set. You'd then use the each() method from Set to iterate over each entry and apply the click event handler. For example:
const map = SVG.get("mysvg");
var restaurants = map.select('[id*="restaurant"]:not(g)'); // Create an svg.js Set, but do not capture the group in the set
restaurants.each(function() {
this.click(function(event) {
this.fill({ color: "#000" });
});
});
If you can edit the svg that you are using as an input, I would suggest adding a class to each of the clickable elements to use that as the reference for select. Otherwise, you'll have to do something like selecting all element id 'types' (i.e. restaurant, retail etc.) separately and concatenating the Sets using Set.add() before you do the loop to add the click listener, but that could get messy.
I'm trying to use nightmare, in node js to click on links based on the text inside the anchor text of the link.
Here's some example code:
var Nightmare = require('nightmare');
var nightmare = Nightmare({show: true})
nightmare
.goto('https://www.wikipedia.org/')
.inject('js', 'C:/users/myname/desktop/nodejs/node_modules/jquery/dist/jquery.js')
.wait(500)
var selector = 'a';
nightmare
.evaluate(function (selector) {
// now we're executing inside the browser scope.
return document.querySelector(selector).innerText;
}, selector) // <-- that's how you pass parameters from Node scope to browser scope
.end()
.then(function(result) {
console.log(result)
})
I'm really unclear on why the inner text of all tags are not returning? I thought I could maybe do an if statement in the .evalution method, so that it would restrict the link to be clicked on to "English" for instance.
Any idea how to click on links based on the link text?
As far as I know, there is no way to select a DOM element solely on what it contains. You'll either need to select all of the anchors (like you're doing now) and filter to what you want based on innerText then issue click events directly, or you could inject jQuery and use :contains and $.click() to issue the click.
Also, if you want all of the text from the tags, you'll likely want to use document.querySelectorAll().
As an example to get all of the text:
.evaluate(function (selector) {
return document.querySelectorAll(selector)
.map(element => element.innerText);
}, selector)
Is there any way to open a custom screen, as placed in the Acumatica menu in the Site map, as a popup (not a new tab) so that it doesn't occupy the existing browser?
I've tried using this, which works ok:
var url = "http://localhost/AcumaticaDB2562/?ScreenId=AC302000&&OpenSourceName=Bills+and+Adjustments&DataID=" + apinvoice.RefNbr;
throw new PXRedirectToUrlException(url, "Open Source")
{
Mode = PXBaseRedirectException.WindowMode.NewWindow
};
The problem is, I don't want the lefthand menu to show up. I just want the screen without any navigation. Is this possible?
I like to use PXRedirectHelper.TryRedirect for calling other graphs. The WindowMode tells the framework how to open the graph. For your question, you will want to use WindowMode.NewWindow as shown in the example below:
var graph = PXGraph.CreateInstance<MyGraph>();
PXRedirectHelper.TryRedirect(graph, PXRedirectHelper.WindowMode.NewWindow);
The enum values for WindowMode are: InLineWindow, New, NewWindow, PopUp, Same.
Alternatively you could do something like this...
throw new PXRedirectRequiredException(graph, true, string.Empty) { Mode = PXBaseRedirectException.WindowMode.NewWindow };
I want to be able to just place a View component (plugin) into the page through code and have it appear at some X\Y on the page... but I'm a bit stumped.
Any attempt to add via page.content kinda adds it to the layout\render pass so it occupies space.
So this would get injected into "any" page at "any" time, I have no control over the markup this would be used in (know what I mean?) There is no XML for it and unfortunately the answer can't just be wrap everything in an AbsoluteLayout because one can't mandate that on users apps\layouts.
Thoughts, even possible?
Basically the simplest way to do this is to dynamically and be fully cross platform compatible is to create a AbsoluteLayout item in your JavaScript code, and dynamically insert your item and the AL into the page container.
Code would be something like this:
var AbsoluteLayout = require('ui/layouts/absolute-layout').AbsoluteLayout;
var myAL = new AbsoluteLayout();
var myItem = new myPluginItem();
// Set you left, right, top, bottom coords.
myItem.top = x;
// Add our item to the AbsoluteItem
myAL.addChild(myItem);
var frame = require('ui/frame');
var page = frame.topmost().currentPage;
var LayoutBase = require('ui/layouts/layout-base').LayoutBase;
page._eachChildView(function(view) {
if (view instanceof LayoutBase) {
view.addChild(myAL);
return false;
}
return true;
});
However, if you don't want to do this the really simple way; the only other way is to actually go a bit lower level. You can natively access the iOS view controller (page._ios.view) and the android view (page._nativeView), and then manually add it to the view by using things like addView (https://developer.android.com/reference/android/view/ViewManager.html) or addSubview (https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/).
I would like to add you can set the Top and Left properties in TypeScript by importing AbsoluteLayout like so
import {AbsoluteLayout} from 'ui/layouts/absolute-layout';
and then using the exposed functions setLeft or setTop
AbsoluteLayout.setLeft(YourItem, LeftValue);
or
AbsoluteLayout.setTop(YourItem, TopValue);
I want to display multiple datasources in a cesiumjs viewer but need to allow the user to select which ones they want to see at any given time. For example, if I load a kml and a czml file, how do I hide one and show the other? I can't find the cesiumjs way to do this with its API.
Update Feb 2016: A show flag has been proposed and may be added to a future version of Cesium.
Original answer:
Currently there is no show flag on the dataSource, however it is easy to add and remove the dataSource from the list of available dataSources, and this is used to get the show/hide functionality.
Here's a working demo: Load the Cesium Sandcastle Hello World example, and paste the following code into the left side, then hit Run (F8). It should display a checkbox in the upper-left with show/hide functionality.
var viewer = new Cesium.Viewer('cesiumContainer');
// Create a typical CzmlDataSource.
var dataSource1 = new Cesium.CzmlDataSource();
dataSource1.load('../../SampleData/simple.czml');
// Add a checkbox at the top.
document.getElementById('toolbar').innerHTML =
'<label><input type="checkbox" id="showCheckbox" /> Show CZML</label>';
var checkbox = document.getElementById('showCheckbox');
checkbox.addEventListener('change', function() {
// Checkbox state changed.
if (checkbox.checked) {
// Show if not shown.
if (!viewer.dataSources.contains(dataSource1)) {
viewer.dataSources.add(dataSource1);
}
} else {
// Hide if currently shown.
if (viewer.dataSources.contains(dataSource1)) {
viewer.dataSources.remove(dataSource1);
}
}
}, false);
This code could be improved, for example it could be a "lazy load" where the dataSource.load does not get called until the first time it's shown. Also if a dataSource has been hidden a while, you have to consider at what point should you be saving memory by destroying the dataSource rather than continuing to hold onto it (triggering a new lazy load if it is later shown again).
as of now, show is a property of the data source, you can control it by accessing the property in dot or bracket notation:
https://cesiumjs.org/Cesium/Build/Documentation/CzmlDataSource.html#show
const src = new Cesium.CzmlDataSource();
src.show = false;
