Im fairly new to SAPUI5 and when I click on button I get the error in the title
what I did in Is I used the SAP web IDE to create new MVC project .
in the main view JS I put
createContent : function(oController) {
var btn = new sap.m.Button({
id:"myBtn",
text : "Content Button"
});
return new sap.m.Page({
title: "TitleT",
content: [ btn ]
});
}
in the Main controller JS I put the following code
onInit: function() {
var that = this;
window.setTimeout(function() {
that.byId("myBtn").setVisible(true);
}, Math.random() * 10000);
},
onPress: function() {
this.byId("pressMeButton").setText("I got pressed");
}
When I run it I see the button but when I click on it I get the error in the on Init,
what am I doing wrong here?
The actual problem with your code is that you create a static id in your javascript view, but the controller will search the id with a prefix like "__jsview0--myBtn" if you call that.byId("myBtn").
Therefore you either have to use createId("myBtn") in your javascript view for defining the id or sap.ui.getCore().byId("myBtn") in the controller and it will work fine. The first approach is recommended though to avoid name clashes.
PS:
i did not really get the use case, it seems like you want to display the button only after a certain (random) timeframe. But the visible flag by default is already true, so the button will always be visible.
Use the standard timeout and byId function from SAPUI5 like this:
onInit: function() {
setTimeout(function() {
sap.ui.getCore().byId("myBtn").setVisible(true);
}, Math.random() * 10000);
},

I'm trying to use the sap.m.Popover as a "rich tooltip" for some controls. This is as per recommendation from SAP because the sap.ui.commons library is now deprecated. We have too much text we want to add to the standard string tooltip. I haven't figured out a way to use the popover directly as a tooltip, which is why I've extended the TooltipBase control to handle the popover.
I've got the popover working fine, However when I interact with my control, I get the following error:
Uncaught Error: failed to load 'myNewToolTip/controls/TooltipBaseRenderer.js' from ../controls/TooltipBaseRenderer.js: 404 - Not Found
I see from these threads that it is because the TooltipBase class is an abstract class and therefore doesn't have a renderer. However, because I'm already using the popover, I don't need to render anything. I've tried to add the TooltipBaseRenderer.js and just have an empty render class. But UI5 really doesn't like that either.
My question is what should I do, I see two options:
There is probably a simple way to use the popover as a tooltip, which I'm just too stupid to figure out (Bear in mind, I'd prefer to bind it directly in the XML view).
Figure out a way to suppress the renderer call as I don't need it.
This is my current source code for the custom control:
sap.ui.define([
"sap/m/Popover"
], function (Popover) {
"use strict";
return sap.ui.core.TooltipBase.extend("myNewToolTip.TooltipBase", {
metadata: {
properties: {
title : {}
},
events: {
"onmouseover" : {},
"onmouseout" : {}
}
},
oView: null,
setView: function(view) {
this.oView = view;
},
onmouseover : function(oEvent) {
var that = this;
if (!this.delayedCall){
this.delayedCall = setTimeout(function() {
if (!that.oPopover){
that._createQuickView();
}
}, 500);
}
},
onmouseout: function(oEvent) {
if (this.oPopover){
this.closePopover();
this.delayedCall = undefined;
}
else{
clearTimeout(this.delayedCall);
this.delayedCall = undefined;
}
},
_createQuickView: function() {
var sTitle = this.getTitle();
this.oPopover = new Popover({
title: sTitle
});
this.oPopover.openBy(this.getParent());
},
closePopover: function(){
this.oPopover.close();
this.oPopover = undefined;
}
});
});
There is no need to create a custom control just to display a popover on mouseover. As you said, there is a simpler way: Adding event delegates.
One of the events that delegates can listen to is onmouseover which can be achieved like this:
this.byId("myTargetControl").addEventDelegate({
onmouseover: function () {
// Open popover here
}
});

Extending sap.ui.core.TooltipBase
If you still consider extending TooltipBase (without Popover), take a look at this example: https://embed.plnkr.co/33zFqa?show=control/MyCustomTooltip.js,preview
Keep in mind, though, that tooltips in general shouldn't contain critical information due to its lack of discoverability as Fiori Design Guideline mentions
Tooltips (...) should never contain critical information. They should also not contain redundant information.
Just as a friendly reminder :) Don't make people hover to find things.
I looked everywhere on the internet but I couldn't find any clear documentation or some examples to create my verySimplePlugin for videoJS 5 (Since it uses ES6).
I just want to add a button next to the big play button... Can someone help me?
Thanks...
PS: I'm using it in angularJS but I guess this can not a problem
This is how you can add download button to the end of control bar without any plugins or other complicated code:
var vjsButtonComponent = videojs.getComponent('Button');
videojs.registerComponent('DownloadButton', videojs.extend(vjsButtonComponent, {
constructor: function () {
vjsButtonComponent.apply(this, arguments);
},
handleClick: function () {
document.location = '/path/to/your/video.mp4'; //< there are many variants here so it is up to you how to get video url
},
buildCSSClass: function () {
return 'vjs-control vjs-download-button';
},
createControlTextEl: function (button) {
return $(button).html($('<span class="glyphicon glyphicon-download-alt"></span>').attr('title', 'Download'));
}
}));
videojs(
'player-id',
{fluid: true},
function () {
this.getChild('controlBar').addChild('DownloadButton', {});
}
);
I used 'glyphicon glyphicon-download-alt' icon and a title for it so it fits to the player control bar styling.
How it works:
We registering a new component called 'DownloadButton' that extends built-in 'Button' component of video.js lib
In constructor we're calling constructor of the 'Button' component (it is quite complicated for me to understand it 100% but it is similar as calling parent::__construct() in php)
buildCSSClass - set button classes ('vjs-control' is must have!)
createControlTextEl - adds content to the button (in this case - an icon and title for it)
handleClick - does something when user presses this button
After player was initialized we're adding 'DownloadButton' to 'controlBar'
Note: there also should be a way to place your button anywhere within 'controlBar' but I haven't figured out how because download button is ok in the end of the control bar
This is how I created a simple button plugin for videojs 5:
(function() {
var vsComponent = videojs.getComponent('Button');
// Create the button
videojs.SampleButton = videojs.extend(vsComponent, {
constructor: function() {
vsComponent.call(this, videojs, null);
}
});
// Set the text for the button
videojs.SampleButton.prototype.buttonText = 'Mute Icon';
// These are the defaults for this class.
videojs.SampleButton.prototype.options_ = {};
// videojs.Button uses this function to build the class name.
videojs.SampleButton.prototype.buildCSSClass = function() {
// Add our className to the returned className
return 'vjs-mute-button ' + vsComponent.prototype.buildCSSClass.call(this);
};
// videojs.Button already sets up the onclick event handler, we just need to overwrite the function
videojs.SampleButton.prototype.handleClick = function( e ) {
// Add specific click actions here.
console.log('clicked');
};
videojs.SampleButton.prototype.createEl = function(type, properties, attributes) {
return videojs.createEl('button', {}, {class: 'vjs-mute-btn'});
};
var pluginFn = function(options) {
var SampleButton = new videojs.SampleButton(this, options);
this.addChild(SampleButton);
return SampleButton;
};
videojs.plugin('sampleButton', pluginFn);
})();
You can use it this way:
var properties = { "plugins": { "muteBtn": {} } }
var player = videojs('really-cool-video', properties , function() { //do something cool here });
Or this way:
player.sampleButton()
I declared a controller for a view in my SAPUI5 application. Now I want to perform tasks when the view is left by the user.
There is already a possibility to add a callback function to attachRoutePatternMatched to perform tasks when the view is navigated by the user now I need a equivalent function to handle a leave of the view. I use a SplitContainer as parent container
onInit: function() {
this._oRouter = this.getOwnerComponent().getRouter();
this._oRouter.attachRoutePatternMatched(this._routePatternMatched, this);
},
_routePatternMatched: function(oEvent) {
var that = this;
var sRouteTargetName = oEvent.getParameter("name");
if (sRouteTargetName === "myView") {
// perform tasks if the view is opened by the user
}
},
You can try if this works:
navAway: function(viewName, callback) {
this._oRouter.navTo(viewName);
if(callback && typeof(callback) === "function") {
callback();
}
}
e.g. this.navAway("myView", function() { //doStuff });
Presume you mean navigating backwards? If you have a back button, which presumably you must, put your actions in that function. E.g your detail/master has a navBack button in the toolbar, so put your logic in the button's event handler...
You can achieve this with BeforeHide delegate on the NavContainer child which is often the view:
onInit: function() {
this._navDelegate = { onBeforeHide: this.onBeforeLeave };
this.getView()/*<-- navContainerChild*/.addEventDelegate(this._navDelegate, this);
},
onBeforeLeaving: function(event) {
// ... do something
},
onExit: function() {
// detach events, delegates, and references to avoid memory leak
this.getView().removeEventDelegate(this._navDelegate);
this._navDelegate = null;
},
Example: https://embed.plnkr.co/wp6yes?show=controller%2FNext.controller.js,preview%23next
API reference: NavContainerChild
API reference: sap.ui.core.Element#addEventDelegate
For other navigation related events, see documentation topics mentioned in https://stackoverflow.com/a/55649563
I have used unified Shell control in order to implement the facebook-like swipe menu and I integrated in it a list so that I can enter menu items. The idea is that when a user clicks on a certain list item in the menu he will get redirected to a new view. I tried to implement it by using bus.publish("nav", "to" {id:..}) but it's not working. (I have put the menu in the Curtain Pane of the Unified Shell) Can anybody help me?
You can find below the respective code snippets of the view and controller.
var oListTemplate = new sap.m.StandardListItem({
title: "{title}",
icon: "{icon}",
description: "{description}",
type: sap.m.ListType.Navigation,
customData: new sap.ui.core.CustomData({
key: "targetPage",
value: "{targetPage}"
})
});
var oList = new sap.m.List({
selectionChange: [oController.doNavOnSelect, oController],
mode: sap.m.ListMode.SingleSelectMaster
});
oList.bindAggregation("items", "/Menu", oListTemplate);
The controller:
onInit: function() {
this.getView().setModel(new sap.ui.model.json.JSONModel("model/menu.json"));
this.bus = sap.ui.getCore().getEventBus();
},
doNavOnSelect: function(event){
if (sap.ui.Device.system.phone) {
event.getParameter("listItem").setSelected(false);
}
this.bus.publish("nav", "to", {
id: event.getParameter('listItem').getCustomData()[0].getValue()
});
Navigation via the sap.ui.core.EventBus is obsolete.
Please have a look at "Navigation and Routing" https://help.sap.com/docs/SAP_NETWEAVER_AS_ABAP_FOR_SOH_740/468a97775123488ab3345a0c48cadd8f/688f36bd758e4ce2b4e682eef4dc794e.html?locale=en-US
A new Routing mechanism was introduced to SAPUI5 in release 1.16. For in-app navigation, this supersedes previous techniques such as using the sap.ui.core.EventBus or sharing navigation-container specific controller code amongst aggregated pages.
Solution: Replace bus.publish with app.to
doNavOnSelect: function(event){
if (sap.ui.Device.system.phone) {
event.getParameter("listItem").setSelected(false);
}
app.to(event.getParameter('listItem').getCustomData()[0].getValue());
}
I am on my way building a Fiori like app using SAPUI5. I have successfully built the Master page, and on item click, I pass the context and navigate to Detail page.
The context path from Master page is something like /SUPPLIER("NAME"). The function in App.controoler.js is as follows:
handleListItemPress: function(evt) {
var context = evt.getSource().getBindingContext();
this.myNavContainer.to("Detail", context);
// ...
},
But I would like to know how I can access this context in the Detail page. I need this because I need to use $expand to build the URL and bind the items to a table.
There is an example in the UI5 Documentation on how to deal with this problem using an EventDelegate for the onBeforeShow function which is called by the framework automatically. I adapted it to your use case:
this.myNavContainer.to("Detail", context); // trigger navigation and hand over a data object
// and where the detail page is implemented:
myDetailPage.addEventDelegate({
onBeforeShow: function(evt) {
var context = evt.data.context;
}
});
The evt.data object contains all data you put in to(<pageId>, <data>). You could log it to the console to see the structure of the evt object.
Please refer the "shopping cart" example in SAP UI5 Demo Kit.

Generally, in 'Component.js', the routes shall be configured for the different views.
And in the views, the route has to be listened to. Please see below.
In Component.js:
routes: [
{ pattern: "cart",
name: "cart",
view: "Cart",
targetAggregation: "masterPages"
}
]
And in Cart.controller.js, the route has to be listened. In this example, cart is a detail
onInit : function () {
this._router = sap.ui.core.UIComponent.getRouterFor(this);
this._router.attachRoutePatternMatched(this._routePatternMatched, this);
},
_routePatternMatched : function(oEvent) {
if (oEvent.getParameter("name") === "cart") {
//set selection of list back
var oEntryList = this.getView().byId("entryList");
oEntryList.removeSelections();
}
}
Hope this helps.
