I have a meteor helper that uses a reactive variable in a find to get a unique document using an id. My item button template looks like this:
<template name = "itemButton" >
<div class = "itemButton" name = {{_id}}>
{{{title}}}
</div>
</template>
using a reactive variable:
Template.landing.onCreated(function _OnCreated() {
this.f = new ReactiveVar();
this.f.set(false);
const handle = Meteor.subscribe("Feed");
});
now I have a method in a template several itemButton.
Template.landing.events({
'click .itemButton' : function(event, template){
alert(event.target.name);
template.f.set(event.target.name);
}
});
and I would like to use that name in a helper that would use this value as the _id.
Template.landing.helpers({
"GetFocus": function(){
alert(Template.instance().f.get()); // alerts undefined...
return(items.find({'_id':Template.instance().f.get()}));
}
});
So where I expect GetFocus to give me the document that generated the button I don't seem to be so lucky. Let me know if I can provide any additional clarification, and as always your input is appreciated.
Where I have template.f.set(event.target.name); I needed template.f.set(event.currentTarget.getAttribute('data-id')); where the html uses data-id instead of name.

I'm unable to get value from h2 tag using protractor.
Html Code:
<h2 class="ng-binding">7</h2>
I need this 7 value. This is from website "http://juliemr.github.io/protractor-demo/". I am adding 5+2.
Appreciate your help.
Try xpath
Here I am getting the element with ID, moving one position back and then looking for the h2
var result = element(by.xpath('//*[#id=\'gobutton\']/../h2'))
result.getText().then(function(value){
expect(value).toBe('7');
})
Or look directly to the h2:
element(by.xpath('//h2[#class='ng-binding']'))
In case you plan to always have 7 as a result then you can also look for the cssContainingText
var result = element.all(by.cssContainingText('.ng-binding', '7')).first();
in this case I am using .all and .first because this will return 2 elements so I am telling protractor to use always the first one
So your code should be something like this:
it('Should access the page and perform sum', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
element(by.model('first')).sendKeys(5);
element(by.model('second')).sendKeys(2);
element(by.id('gobutton')).click();
var result = element(by.xpath('//*[#id=\'gobutton\']/../h2'))
result.getText().then(function(value){
console.log('result is '+value)
expect(value).toBe('7');
})
});
As per the url given, After clicking Go it loads for some time. So add some wait and then try to getText() with the below locator.
browser.sleep(5000);
element(by.css('form>h2.ng-binding')).getText().then((text: String) =>{
expect(text).toBe("7");
})
Hope it helps you...
First, you find the element, for example with a by.css call. Then you use getText method to retrieve the desired tag content. Finally, you assert it to be equal to the value you expect:
result = element(by.css('h2.ng-binding'))
expect(result.getText()).toEqual('7')
This has been driving me nuts - hoping someone can help me.
I have a multifield component called 'books' with a single textfield: 'title'.
Everything seems to be working; the dialog box contains the multifield then I add two title fields then enter 'title1' and 'title2'.
then in the HTML itself I go:
<div data-sly-repeat="${properties.books}">
<p>${item}</p>
<p>${itemList.index</p>
<p>${item.title}</p>
</div>
What I don't get is, ${item} correctly gives me:
{"title": "title1"} {"title": "title2"}
and ${itemList.index} correctly gives me: 0 1
but ${item.title} keeps coming up blank. I also tried ${item["title"]} and that comes up blank too.
What am I doing wrong here? In my desperation I contemplated using
<div data-title="${item}"></div>
and then using JS to process the JSON object but I don't really want to do that.
Someone help, please!
It looks like your books property is either a JSON array string or a multivalued property with each value being a JSON object string;
The easiest way to parse the property is via a JS model like the following:
You could simplify this script to match your specific case, I made it general to multi-value and non-multi-value string properties.
/path/to/your-component/model.js:
"use strict";
use(function () {
// parse a JSON string property, including multivalued, returned as array
function parseJson(prop){
if(!prop) return [];
var result =[];
if(prop.constructor === Array){
prop.forEach(function(item){
result.push(JSON.parse(item));
});
}
else {
var parsed = JSON.parse(prop);
if(parsed.constructor === Array){
result = parsed;
}
else result = [parsed];
}
return result;
}
var $books = properties.get("books", java.lang.reflect.Array.newInstance(java.lang.String, 1));
var books = parseJson($books);
return {
books: books
}
});
/path/to/your-component/your-component.html:
<sly data-sly-use.model="model.js"/>
<div data-sly-repeat="${model.books}">
<p>${item}</p>
<p>${itemList.index</p>
<p>${item.title}</p>
</div>
I'm trying to load data from an ajax source into angular datatable but it's not even hitting the ajax call.
var analyzer=angular.module('analyzer', ['datatables']);
analyzer.controller('WithAjaxCtrl', WithAjaxCtrl);
function WithAjaxCtrl(DTOptionsBuilder, DTColumnBuilder) {
var vm = this;
$scope.dtOptions = DTOptionsBuilder.fromSource('/analyzer/List')
$scope.dtColumns = [
DTColumnBuilder.newColumn('BuildName').withTitle('Name'),
DTColumnBuilder.newColumn('Total').withTitle('Total'),
DTColumnBuilder.newColumn('Passed').withTitle('Passed'),
DTColumnBuilder.newColumn('Failed').withTitle('Failed')
];
}
Here's the html code for the table-
<div ng-controller="WithAjaxCtrl">
<table datatable="" dt-options="dtOptions" dt-columns="dtColumns" class="row-border hover"></table>
</div>
data from ajax source is in the form -
{"responseCode":0,"responseData":[{"Name":"Rob","Total":6273,"Passed":5874,"Failed":399}]}
So will i have to define the datasrc ?
Yes, you need to specify the dataSrc since your rows is contained in responseData, not in the default or expected data property. In angular dataTables there is an option setter named withDataProp() :
$scope.dtOptions = DTOptionsBuilder.fromSource('/analyzer/List')
.withDataProp('responseData')
Cannot link directly but look at https://l-lin.github.io/angular-datatables/#/api
So here is my quick code.
var thisisformykeyorid =$scope.id;
var ref = firebase.database().ref('/myusers/').child("users");
$scope.users= $firebaseArray(ref);
var query = ref.orderByChild("timestamp").limitToLast(100);
$scope.filteruser= $firebaseArray(query);
In my HTML is
<div ng-repeat="samplein filteruser>
<h2>{{ sample.firstname}}</h2>
<p>{{ sample.age}}</p>
</div>
So in firebase there are unique id or keys for each set of data.
How do i add a filter or query to select a set of data from firebase using my variable ? (assuming $scope.id is a unique key) Please be guided that i dont want to use ng-repeat anymore because i only want to view only 1 set of data. Need help
If you know what object you want to display, you can use $firebaseObject instead of $firebaseArray:
var ref = firebase.database().ref('/myusers/').child("users");
$scope.user = $firebaseObject(ref.child($scope.id));
And then display it in your HTML with:
<div >
<h2>{{user.firstname}}</h2>
<p>{{user.age}}</p>
</div>
In jQuery, there is a function to serialize a form element so for example I can submit it as an ajax request.
Let's say we have a form such as this:
<form id="form">
<select name="single">
<option>Single</option>
<option selected="selected">Single2</option>
</select>
<input type="checkbox" name="check" value="check1" id="ch1">
<input name="otherName" value="textValue" type="text">
</form>
If I do this with the help of jquery
var str = $( "form" ).serialize();
console.log(str);
the result would be
single=Single2&check=check1&otherName=textValue
Is there such functionality in dart's FormElement or I have to code it myself? Thanks.
I came up with my own simple solution that might not work in all cases (but for me it is workikng). The procedure is this:
First we need to extract all input or select element names and values from the form into Dart's Map, so the element name will be the key and value the value (e.g. {'single': 'Single2'}).
Then we will loop through this Map and manually create the resulting string.
The code might look something like this:
FormElement form = querySelector('#my-form'); // To select the form
Map data = {};
// Form elements to extract {name: value} from
final formElementSelectors = "select, input";
form.querySelectorAll(formElementSelectors).forEach((SelectElement el) {
data[el.name] = el.value;
});
var parameters = "";
for (var key in data.keys) {
if (parameters.isNotEmpty) {
parameters += "&";
}
parameters += '$key=${data[key]}';
}
Parameters should now contain all the {name: value} pairs from the specified form.
I haven't seen anything like that yet.
In this example Seth Ladd uses Polymers template to assign the form field values to a class which get's serialized.
