I'm using both the 1.5.1 and 1.6.0 to test my apps on my OS X.
I'm trying to update some values in this array:
var myTab = [
{title:'foo1',value:'bar1'},
{title:'foo2',value:'bar2'}
];
If I update a value field in this array, it doesn't do it (which isn't normal):
Titanium.API.info('Before :' + myTab[0].value);
myTab[0].value = 'updated!';
Titanium.API.info('After :' + myTab[0].value);
It displays 'bar1' instead of 'updated!'.
What I tried next is to put the tab as a property list:
Titanium.App.Properties.setList('propTab',myTab);
And then, I tried to do the same thing:
Titanium.API.info('Before :' + Titanium.App.Properties.getList('propTab')[0].value);
Titanium.App.Properties.getList('propTab')[0].value = 'updated!';
Titanium.API.info('After :' + Titanium.App.Properties.getList('propTab')[0].value[0].value);
Same result: It displays 'bar1' instead of 'updated!'.
Is there another solution?
Thank you,
Regards
I've run into this sort of behavior before. While I never ascertained the cause, I found a workaround: you need to set myTab[0] to a value, and not myTab[0].value to a value. So, thus:
myTab[0] = {title: myTab[0].title, value: "updated!"};
Why, I do not know... I should probably figure it out.
You need to mention it as an array element then it should work. For e.g., in your case you may modify as foolows
myTab[0]['value'] = 'updated!';

As #vadian suggested, I am learning Xcode from Paul Hudson's 100 days of SwiftUI to better understand the basics (even though I am still struggling with time to deliver working GitHub repository search - no it is not for the job I am working on right now).
I am doing a lesson on Arrays, so pretty basic stuff right now and I struggle to map the String from array on the sorted array. I don't get why, but I get the:
Ambiguous use of 'init'
error.
Here's the code:
let cities = ["London", "Tokyo", "Rome", "Budapest"]
print(cities.sorted())
let citiesSorted = cities.sorted()
let citiesSortedString = citiesSorted.map(String.init).joined(separator:", ")
And it's so really strange, since I pulled the similar thing out before in the same Playground but not with the sorted Array:
var schoolScoresString = schoolScores.map(String.init).joined(separator:", ")
print(schoolScoresString)
And yes I tried changing let to var. It didn't help.
cities is already of type [String], so you're passing a String to String.init, which obviously won't work. If you want to join an array of Strings into a single String, remove the map and just call joined on the array.
let citiesSortedString = citiesSorted.joined(separator:", ")
I'm creating an app in Reactjs using react-strap. I would like to convert an input field to upper case.
From googling, it looks like simply appending "toUpperCase()" to the field would work, but this doesn't appear as an option in Visual Studio code.
I had a similar issue with doing a replace all, but finally got that to work using "const" field:
// replace ":" with "-"
const phrase = item.macs;
const replaced = phrase.replace(/:/g, '-')
item.macs = replaced;
However, converting to a const field doesn't work for making the "toUpperCase()" available.
What should I do to turn this into a string so I can call the "toUpperCase()" function?
Edit: change references from "toUpper" to "toUpperCase". The problem is this is not available as a function.
For example of I do
'myString'.toUpperCase();
it works. But it I can't get it to bring that up in Visual Studio Code, and it's ignored if I code it anyway.
I believe you are looking after toUpperCase.
To make a string uppercase in javascript you can call .toUpperCase() method on it. For example
const foo = 'foo'
const fooUpper = foo.toUpperCase()
console.log(fooUpper) // expected result 'FOO'
I got around this problem by forcing the input item to be regarded as a string by prepending it with a '', like so:
item.macs = '' + item.macs;
item.macs = item.macs.replace(/:/g, '-');
item.macs = item.macs.toUpperCase();
After that, all the string functions were available.
In reactjs I want to display a property.
Normally this isn't really hard to do it, but this time there is a number in the property. And that number depends on how many links the user has added.
This is an example of what my api returns to my react app:
embed_links: ["2"]
embed_links_0_embed_link: ["https://www.url.com"]
embed_links_1_embed_link: ["https://www.url.com"]
The embed_links is an array which says how many urls the user has filled in.
Then you get the urls the user has filled in, and each one has a number in it.
This is where I got stuck. I have tried to display the links with a for loop like this:
let embed_links = this.props.embed_links[0]
for (let i = 0; i < embed_links; i++) {
console.log(this.props.embed_links_[i]_embed_link[0]);
}
But this does not work..
So my question is basically, is there a possibility that you can display properties witch custom variables/numbers in it?
If you are asking access to a dynamical property within your object:
console.log(this.props["embed_links_" + i + "_embed_link"][0]);
Your syntax is wrong, the correct way to write this is as follows:
let embed_links = this.props.embed_links[0]
for (let i = 0; i < embed_links; i++) {
console.log(this.props['embed_links_' + i + '_embed_link][0]);
}
In the example, 'embed_links_' + i + '_embed_link' is the key that you use to select the correct property of object props.
Yes you can use this.props['embed_links_' + i + '_embed_link'][0]
However i would suggest storing your embed links in an array as objects
embed_links_collection: [
{
url:'https://www.url.com',
id: '1'
}
]
This is a cleaner, managable solution - you could also generate your embed_links property as this.props.embed_links_collection.length
You can use for .. in for enumerating this.props properties
I tried this :
$row = JTable::getInstance('K2Item', 'Table');
$row->load($myId);
//change something
$row->title = 'New title';
$row->save(); // doesn't work
$row->checkin(); // doesn't work either
I was going also through most of the K2 code but it seems to rely on request variables and I have a hard time to understand that code at all.
Does anyone knows what's the right procedure?
thanks
I have a test that checks the value an HTML5 range input.
return this.remote
// etc.
.findById('range')
.getAttribute("value")
.then(function(val){
expect(parseInt(val)).to.equal(2);
});
The value is correct when I check its initial value, but if I change the value then check, it has not been updated. I found that the value doesn't update in the developer tools either. I tried using
.sleep(3000)
between changing the value and calling
.getAttribute('value')
but that didnt' seem to be the issue.
In this JSfiddle, inspecting the range element with your browser's developer tools will show the title change, but the value does not (even though the value is correctly changed in the textbox). So this may be an issue with the webdriver, but I'd like to know if anyone has run into this issue.
Is this related to the test's failure to get the updated value? Is there another method I can use to read values(attributes)?
Edit:
It seems like the browser's onchange/oninput event is not triggering properly (similar problems: WebDriver: Change event not firing and Why does the jquery change event not trigger when I set the value of a select using val()?), and the webdriver is possibly not able to, either. Do I have to add Jquery as a define for my test, even though I only need to use trigger() ? Or is there another solution?
Edit2: I've added a better example of how I'm using the range input in this new JSfiddle. I added plus/minus buttons, which fail to trigger the change event that should update the value attribute of the range input, (and which fails to enter the value into the textbox).
You could fire the change event manually in your test. I was able to get the 'textValue' input in your JSFiddle to update that way and I imagine it might work similarly in your test.
rangeBar = document.querySelector('#range');
function myFire(element, eventType) {
var myEvent = document.createEvent('UIEvent');
myEvent.initEvent(
eventType, // event type
true, // can bubble?
true // cancelable?
);
element.dispatchEvent(myEvent);
}
myFire(rangeBar, 'change');
This comes up often enough that I have a helper in my base test class (Java)
public enum SeleniumEvent
{blur,change,mousedown,mouseup,click,reset,select,submit,abort,error,load,mouseout,mouseover,unload,keyup,focus}
public void fireEvent(WebElement el, SeleniumEvent event)
{
((JavascriptExecutor) getDriver()).executeScript(""+
"var element = arguments[0];" +
"var eventType = arguments[1];" +
"var myEvent = document.createEvent('UIEvent');\n" +
"myEvent.initEvent(\n" +
" eventType, // event type\n" +
" true, // can bubble?\n" +
" true // cancelable?\n" +
");\n" +
"element.dispatchEvent(myEvent);", el, event.toString());
}
Another thought. getAttribute("value") might not be getting what you think it does. In JavaScript, document.querySelector('#range').getAttribute('value') always returns the hard-coded value attribute (i.e. the default or initial value), not the input's current value.
document.querySelector('#range').value returns the current value.
