This is the outcome I am looking for:
$scope.donotShow = false;
The way I want to get it is in the controller in which I have one variable to work with:
var slug = "donot";
I would like to combine it with the string "Show":
var slugshow = slug + "Show";
From here I want the outcome I am looking for but this does not work:
$scope.slugshow = false;
How do I make the var slugshow show as "donotShow" thus giving me
$scope.donotShow = false;

Using shared preferences to save an arrayListOf in my app. Im converting the array to a hashset and saving it but when I load it I am unable to convert it back to an arrayListOf. I have tried toTypedArray() and toArray() but neither solve the problem. Getting the error below.
Required:
kotlin.collections.ArrayList /* = java.util.ArrayList */
Found:
(Mutable)Set<String!>?
Using the following to try and load the hashet and convert it.
var sharedPreferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE)
var places = arrayListOf<String>()
var loadSet = sharedPreferences.getStringSet("key", null)
places = loadSet
go.setOnClickListener{
thread {
val place = newLocation.text.toString()
var stringCounter = counter.toString()
if(place !in places){
places.add(place)
//editor.putStringSet("key", places)
//editor.commit()
var sharedPreferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE)
var editor = sharedPreferences.edit()
set.add(place)
editor.putStringSet("key", set);
editor.commit();
Log.d("set", set.toString())
var loadSet = sharedPreferences.getStringSet("key", HashSet<String>())?.toList()
Log.d("load", loadSet.toString())
places = loadSet as ArrayList<String>
}
arrayListOf isn’t a type. It’s a function. The type is ArrayList, but it’s more typical to only need the more abstract List or MutableList, depending on what you’re doing with it. For those you can use set.toList() or set.toMutableList().
If you have an existing ArrayList or MutableList, you could also do list.addAll(set).
var ss = SpreadsheetApp.openByUrl('https://docs.google.com/spreadsheets/d/1Ow_rhF3sibKL3OAQRXpK6LLZDjMOhW-5DKyWWiN5iZg/edit#gid=638513192');
var data = SpreadsheetApp.setActiveSheet(ss.getSheetByName('Graficos'));
Logger.log(SpreadsheetApp.getActiveSpreadsheet());
var ergo = data.getRange(3,2,4,1);//B3:B6 '
My guess to access the elements was to call var i = ergo[0]; but it didn't work. Do I have to declare ergo using a different syntax?
You need to use getValues() on the range, which will return a 2-dimensional array.
var ergo = data.getRange(3,2,4,1).getValues();
Also, you're not coding efficiently as you're essentially duplicating actions in your first two lines. Take a look at this refactoring:
function test() {
var ss = SpreadsheetApp.openByUrl('https://docs.google.com/spreadsheets/d/1Ow_rhF3sibKL3OAQRXpK6LLZDjMOhW-5DKyWWiN5iZg/edit#gid=638513192');
var data = ss.getSheetByName('Graficos');
ss.setActiveSheet(data); // There doesn't seem to be a need to do this, so maybe delete this line
var ergo = data.getRange(3,2,4,1).getValues(); //B3:B6
}
I am currently working on my project using angularjs. I got everything already it is just that, i need to convert the dictionary list to a string separated by comma. I can only do this using python.
[{"name":"john"},{"name":"mark"},{"name":"peter"}]
I want to convert them to string
"john,mark,peter"
I would really appreciate your help. :)
.map and then .join will do
var array = [{"name":"john"},{"name":"mark"},{"name":"peter"}];
var names = array.map(function(item) {
return item.name;
}).join(',');
The map() method creates a new array with the results of calling a function for every array element. Use this to loop and then add that value to a variable.
var dict=[{"name":"john"},{"name":"mark"},{"name":"peter"}];
var string;
dict.map(function(value){
//do any stuff here
string+=value["name"]+",";
});
console.log(string);
Try map function to concatenate the values:
var dict=[{"name":"john"},{"name":"mark"},{"name":"peter"}];
var str="";
dict.map(function(a){
str+=a["name"]+",";
});
//feels ironical as question has AngularJS tag
document.getElementById("log").innerText=str;
<div id="log"></div>
You can simply iterate over each key-value pair and concat the extracted value with comma.
var obj = [{"name":"john"},{"name":"mark"},{"name":"peter"}]
var result = '';
for (var p in obj) {
if (obj.hasOwnProperty(p)) {
result += obj[p].name + ",";
}
}
result = result.replace(/,$/g,''); // to trim trailing comma
I have a scope variable that returns me an absolute url stored by the user. While displaying I would like to only show the host name for the given object.
for example.
$scope.url ="www.myurl.com/zyas?nxs"
i want to only display it as www.myurl.com.
How can I achieve this?
Have a look at the below code
string s = "www.myurl.com/zyas?nxs";
string newstr = s.split("/"); //newstr == "www.myurl.com"
You can do like this:
$scope.url ="www.myurl.com/zyas?nxs"
$scope.host = $scope.url.split('/')[0];
var hostName = $scope.url.split('/')[0];
I went with the normal split provided by JavaScript. Here's how I parsed it to the hostname and pushed it back to my JSON object.
$scope.blogposts = result.data
// console.log(urls);
$scope.blogposts.forEach(function(blog){
console.log(blog);
var a = blog.url.split('/')
// blog.push({'viewUrl':'a[0]'})
blog["viewUrl"] =a[0]
})
In a better way, you can do this without splitting and doing things
var url = new URL("http://www.myurl.com/zyas?dsfadf");
console.log(url.host); // gives the host name www.myurl.com
I have created an array which is being used to store a series of .gif images and I'm just trying to test everything out by using document.getElementById to change the .src value but when I change it and load the page the image stays the same as it was before.
function setImage()
{
var images = new Array();
images[0] = anemone.gif;
images[1] = ball.gif;
images[2] = crab.gif;
images[3] = fish2.gif;
images[4] = gull.gif;
images[5] = jellyfish.gif;
images[6] = moon.gif;
images[7] = sail.gif;
images[8] = shell.gif;
images[9] = snail.gif;
images[10] = sun.gif;
images[11] = sunnies.gif;
images[12] = whale.gif;
var slots = new Array();
slots[0] = document.getElementById("slot" + 0);
slots[1] = document.getElementById("slot" + 1);
slots[2] = document.getElementById("slot" + 2);
slots[0].src = "snail.gif";
document.getElementById('slot0').src = images[0];
alert(images.length);
}
I can't understand why the image wont change, but I know it has to be something very simple. I've been wasting hours trying to get this one thing to change but nothing works. can anyone please point out the error of my ways?
There are a couple of issues with your code:
Your filenames need to be Strings, so they'll have to be quoted (also you can simplify the Array creation):
var images = ['anemone.gif', 'ball.gif', 'crab.gif', 'fish2.gif', 'gull.gif', 'jellyfish.gif', 'moon.gif', 'sail.gif', 'shell.gif', 'snail.gif', 'sun.gif', 'sunnies.gif', 'whale.gif'];
Also make sure you are getting your slot-elements right, quote all the attributes like:
<img id="slot0" class="slot" src="crab.gif" width="120" height="80">
When you create the slots-Array you can do it like this (no need to concat the ID string):
var slots = [document.getElementById('slot0'), document.getElementById('slot1'), document.getElementById('slot2')];
Finally make sure you call your function when the document has loaded / the DOM is ready. If you don't want to use a framework like jQuery your easiest bet is probably still using window.onload:
window.onload = setImage; //note that the parens are missing as you want to refer to the function instead of executing it
