HTML service error creating elements dynamically - google-apps-script

I'm working with html service of google-apps-script and I'm writing some modules to make life easier. The module below its designed to create elements fast and easy with an easy to read notation.
All works fine except the text function. It uses the input function to create a specific input type. In this case, a text one. When I try to use it I get the following error:
Untaming of guest constructed objects unsupported
I can't understand this error. Could anyone explain it to me?
var util = {
create: (function(){
var element = function (elementName,atributes ){
var element = $( document.createElement(elementName) );
return atributes ? element.attr(atributes) : element;
},
div = function(atributes){ return element('div',atributes); },
textArea = function(atributes){ return element('textarea',atributes); },
input = function(atributes){ return element('input',atributes); },
text = function(atributes){
atributes.type = "text";
return input(atributes);
};
return { div:div, input : input, text:text, textArea:textArea}
})()
};

how to trigger a function in vuejs after the page is loaded?

I am trying to trigger a function which hides or show the images on the basis of data i have written two function one which calls the api which is in created hook and second function which renders the image . The problem is how do i call that second function after the dom is loaded , right now when i am trying to call in the first function or created it is returning me error that css cannot be changed of null.I have tried using mounted function with newtick but its still firing the render_badges function first and hence values are null inside
created:function(){
this.loadlike()
},
methods:{
loadlike:function(){
var self = this
this.$http.get('/api/user_profile').then(function (res) {
self.tasksdata = res.body
self.badges = self.tasksdata.data2
console.log(self.badges)
console.log(this.tasksdata)
console.log(this.max)
})
},
getHumanDate : function (date) {
return moment(date, 'YYYY-MM-DD hh-mm-ss').locale("en-gb").format('LL');
},
render_badges:function(){
var self = this
var counter = 0;
self.badges.map(function(e){
counter ++;
console.log(counter)
if(counter <=self.max){
document.getElementById("i").style.display = "initial";
}
else{
document.getElementById("i").style.display = "none";
}
})
},
mounted: function () {
this.$nextTick(function () {
this.render_badges();
})
}
Rather than manipulating the DOM, you should use v-if on the element itself that turns it on or off based on data. It is a different way of thinking than direct DOM manipulation learned in the jQuery days. Read more in the Vue docs about conditional rendering.
If you are wanting to trigger once the DOM is available, use mounted()

TVML listItemLockup click event

I'm using the 'Compilation.xml' template from the TVMLCatalog
I'd like to add a button click event to a 'listItemLockup'
<listItemLockup>
<ordinal minLength="2" class="ordinalLayout">0</ordinal>
<title>Intro</title>
<subtitle>00</subtitle>
<decorationLabel>(3:42)</decorationLabel>
</listItemLockup>
I've tried adding:
App.onLaunch = function(options) {
var templateURL = 'http://localhost:8000/hello.tvml';
var doc = getDocument(templateURL);
//doc.addEventListener("select", function() { alert("CLICK!") }, false);
var listItemLockupElement = doc.getElementsByTagName("listItemLockup");
listItemLockupElement.addEventListener("select", function() { alert("CLICK!") }, false);
}
addEventListener
void addEventListener (in String type, in Object listener, in optional Object extraInfo)
Is "select" the correct type?
I've been using the following tutorials
http://jamesonquave.com/blog/developing-tvos-apps-for-apple-tv-with-swift/
http://jamesonquave.com/blog/developing-tvos-apps-for-apple-tv-part-2/
Update
I'm getting an error
ITML <Error>: doc.getElementsByTagName is not a function. (In 'doc.getElementsByTagName("listItemLockup")', 'doc.getElementsByTagName' is undefined) - http://localhost:8000/main.js - line:27:58
I tried adding this to the 'onLaunch'
var listItemLockupElements = doc.getElementsByTagName("listItemLockup");
for (var i = 0; i < listItemLockupElements.length; i++) {
//var ele = listItemLockupElements[i].firstChild.nodeValue;
listItemLockupElements[i].addEventListener("select", function() { alert("CLICK!") }, false);
}
I'll see about the error first

More common example I have seen by Apple is to define a single overall listener like:
doc.addEventListener("select", Presenter.load.bind(Presenter));
In your xml, assign unique ids to elements, or give them ways to identify them.
For example, the beginning would be something like:
load: function(event) {
var self = this,
ele = event.target,
attr_id = ele.getAttribute("id"),
audioURL = ele.getAttribute("audioURL"),
videoURL = ele.getAttribute("videoURL")
And then you can do whatever you want with your item.
if(audioURL && (event.type === "select" || event.type === "play")) {
//
}
My advice would be to study the Presenter.js file more carefully for this pattern.
Edit:
Answering your "Update" related to doc.getElementsByTagName is not a function. "doc" does not actually exist, but the general pattern is to get it with
var doc = getActiveDocument();
I assumed you would know the above.
Does that fix it?
var listItemLockupElement = doc.getElementsByTagName("listItemLockup”);
In this case, the listItemLockupElement is a NodeList, not an element. You can either iterate through the list and add an event listener to each listItemLockup, or you could add the event listener to the containing element.
When addressing items in a NodeList, you use the item(i) method rather than the standard array access notation:
listItemLockupElements.item(i).addEventListener("select", function() { })
See: https://developer.mozilla.org/en-US/docs/Web/API/NodeList/item
Adding event listeners is straightforward if you're using atvjs framework.
ATV.Page.create({
name: 'mypage',
template: your_template_function,
data: your_data,
events: {
select: 'onSelect',
},
// method invoked in the scope of the current object and
// 'this' will be bound to the object at runtime
// so you can easily access methods and properties and even modify them at runtime
onSelect: function(e) {
let element = e.target;
let elementType = element.nodeName.toLowerCase();
if (elementType === 'listitemlockup') {
this.doSomething();
}
},
doSomething: function() {
// some awesome action
}
});
ATV.Navigation.navigate('mypage');
Disclaimer: I am the creator and maintainer of atvjs and as of writing this answer, it is the only JavaScript framework available for Apple TV development using TVML and TVJS. Hence I could provide references only from this framework. The answer should not be mistaken as a biased opinion.

LiveValidation plugin - HTML in failureMessage

I am using the LiveValidation plugin and was wondering of there is a way to add HTML in the span tags that show a valid or invalid message. I have the following:
var validatedObj = new LiveValidation('momlastname', { validMessage: ""});
validatedObj.add(Validate.Presence,{ failureMessage: "You need a name in this <strong>field</strong>"});
But when I test the code I get this:
Imgur
What am I missing?
It is not implemented, failureMessage parameter is treated as string. Here is function that creates message ( source ), so you can change that:
createMessageSpan: function(){
var span = document.createElement('span');
var textNode = document.createTextNode(this.message);
span.appendChild(textNode);
return span;
},
It is also possible to override onValid and onInvalid default callbacks, and to impliment your own functionality. Check the official documentation for more info.
Thanks #Danijel. I modified the function as follows:
createMessageSpan: function () {
var span = document.createElement('span');
span.innerHTML = this.message;
return span;
},

SAPUI5 get single property from JSON-Model

I am currently trying to figure out how I can retrieve a single value from a sap.ui.model.json.JSONModel
in my main view:
var gConfigModel = new sap.ui.model.json.JSONModel();
var getConfigCallback = function(config) {
gConfigModel.setData(config);
};
oController.getConfiguration(getConfigCallback);
console.log(gConfigModel);
in my controller:
getConfiguration : function(callback) {
var sServiceUrl = "/sap/opu/odata/sap/xxx/ConfigurationSet('Initialize')";
var config = {};
callback(config);
$.getJSON(sServiceUrl).done(function(data) {
config = data.d;
callback(config);
});
},
In my console.log statement I can see that the data was successfully passed from the backend and successfully set to the JSON model. My requirement is to store the value of attribute Editable in a single variable.
I already tried gConfigModel.getProperty('/'), didnt work. tried to access gConfigModel.oData was undefined .. How can I store it in a single value?
Solution Comment: If you catch data from a backend, you have to take care how long it takes. data can be available later then expected, in my case I added 1s timeout, afterwards I can access the property easily
setTimeout(function() {
console.log(gConfigModel.getProperty('/Editable'));
}, 1000);
I wouldn't advise using the model's getData() method since it is deprecated.
A much better solution is to use gConfigModel.getProperty("/Editable")
(I'm using the root slash here since your property resides in the root of your model)
In the same way, you can also set your data:
gConfigModel.setProperty("/Editable", <your new value>) instead
First of all, thanks for the effort to find solutions of our Problems! (at least, those regarding It stuff.. :) )
I've found a solution which I think is a little bit more save because the timeout is maybe somewhat arbitrary - it would depend on the machine or the amount of data that is to be fetched?
Therefore, I am using an attachRequestCompleted function:
with sUrl_2="path-to-my-service";
var oModel_2 = new sap.ui.model.json.JSONModel(sUrl_2);
oModel_2.attachRequestCompleted(function(data) {
//now, i can access the data stored in the oModel_2, either by getProperty, or by DOM: oModel_2.oData.d.Vendor
gv_selLieferant = oModel_2.getProperty("/d/Vendor");
gv_selEinkOrg = oModel_2.getProperty("/d/PurchOrg");
gv_selEinKGru = oModel_2.getProperty("/d/PurGroup");
});
<script src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js" id="sap-ui-bootstrap" data-sap-ui-theme="sap_bluecrystal" data-sap-ui-libs="sap.m"></script>

function getConfiguration(callback) {
var sServiceUrl = "/sap/opu/odata/sap/xxx/ConfigurationSet('Initialize')";
var config = {};
var data = {

"_metadata": "",
"Backup01": "01",
"Editable": "True"
}
};
setTimeout((function() {
config = data;
callback(config);
})(), 2000);
};
var gConfigModel = new sap.ui.model.json.JSONModel();
var getConfigCallback = function(config) {
gConfigModel.setData(config);
alert(gConfigModel.getProperty("/d/Editable"));
};
getConfiguration(getConfigCallback);

backbone.js fetch json success will not hit

i use fetch from backbone.js to load a json model but success will not hit.
var DialogModel = Backbone.Model.extend({
url : function() {
return '/messages/getDialog';
},
parse : function(res) {
return res.dialog;
}
});
var DialogView = Backbone.View.extend({
el: $("#page"),
initialize: function() {
var onDataHandler = function() {
this.render();
};
this.model = new DialogModel();
this.model.fetch({ success : onDataHandler});
},
render: function(){
var data = {
dialogModel : this.model
};
var form = new Backbone.Form({
model: data
});
$(this.el).html(form.render().el);
}
});
What happens now:
DialogView initialize is called.
this.model.fetch is called but the onDataHandler function will not be hit if success.
/messages/getDialog throws a json file back.
The json file is loading well as i can see in the network browser.
Thanks for your help!
Oleg
The problem you're having is due to a typical JS gotcha and not related to Backbone itself. Try
var that = this;
this.model.fetch({
success : function () {
that.render();
}
});
The way you're currently passing onDataHandler is problematic as it will cause this to refer to the global object instead of the DialogView, when the function is called.
This fiddle demonstrates the problematic version vs one that works.
(You may also want to take a look at JS strict mode which can shield you from this type of errors.)
Even better is to listen for an event:
this.model.on("sync", this.render).fetch();
I ran across this question while looking for something else, but the currently accepted answer drives me nuts. There's no good reason to be sprinkling this and that all over your code. Backbone (underscore) includes a context parameter that you can bind to.
that = this makes no sense. If you must implement obsolete 2007-era Crockford patterns, then say var self = this. Saying that = this is like saying left = right. Everyone Stop.
