I would like an example to check a column for "ok" text.
When text is found, I will give an instruction.
How can I do this?
Thanks
You should try to do a little more research before posting questions, but here is a basic formula that will do what you need.
function checkColumn(theRange,textToFind) {
for(var i=0;i<theRange.length;i++){
if(theRange[i].includes(textToFind)){
return true;
}
}
return false;
}

I have an object of $person as below:
$person = Person::where('id', $id)->first();
According to which $person exists or not I load other data:
if($person) {
$person->family_members = FamilyMemberController::FamilyMemberOf($person->id);
} else {
$person->family_members = [];
}
In the view file, I check the $person->family_members if not empty and exists to add a generated value :
if(!empty(array_filter($person->family_members))) {
// my code
}
But it throws an error:
array_filter(): Argument #1 ($array) must be of type array, Illuminate\Database\Eloquent\Collection given
I need to check this $person->family_members to make sure whether it's an array or a collection is not empty.
Writing code for if array do something if collection do something is the wrong way of implementation.
You can do two things.
use both returns as collection()
or either use both returns as an array[]
If collection
else {
$person->family_members = collect();
}
If array
use ->toArray() at the end of Eloquent. Check this answer
As well, I think you are confused with array_filter(). Maybe you are searching for in_array() or contains()
Use count method
if(count($person->family_members)>0){
//your code
}
We don't know your code, but given the error, it's safe to assume your method returns a Collection. You can see available methods in the docs. However, if you need it as array, all you need to do is call ->toArray() on the result Collection. Then you can use array_filter.
What about just doing
if(!$person->family_members){
// your code here
}
or
if($person->family_members){
// your code here
} else {
// code of "if it's empty" goes here
}
You can use the count() function to return a count of an index. ex
if(count($person->family_members)){
//do your true algo
}
Why you are using the empty method ?! Try this:
$person->family_members = $person ? FamilyMemberController::FamilyMemberOf($person->id) : null;
if($person->family_members){ // your code }
Try simple ways in Programming ;)
In my code, I have to check an array contains a specific item or not.
Here is my code
If error.errors[0].peoples = .noteEntered {
Print("something")
}
To learn better, can I ask you to show me how to do it in the better way, I think it's not good.
Many thanks
You can try
if error.errors.contains(where:{$0.peoples == .noteEntered}) {
print("something")
}
If you need the item do
if let item = error.errors.first(where:{$0.peoples == .noteEntered}) {
print(item)
}
if error.errors[0].peoples.contains(.noteEntered) {
print("something")
}
how can i check if any javaScript object's property exists and if it exists then it has a valid value?
actually,i am a beginner and trying to solve this-
Check if the second argument is truthy on all objects of the first argument(which is an array of objects).i.e.
check if the second argument exists in all the objects in first argument(an array) as a property.
if it exists, it should not be-
invalid, as age can't be 0
null
undefined
empty string('')
NaN
till now i have this-
function truthCheck(collection, pre) {
for(var i=0;i<collection.length;i++){
if(!(pre in collection[i])||collection[i]
[pre]===undefined||isNaN(collection[i]
[pre])||collection[i][pre]===""||
collection[i][pre]===null||collection[i]
[pre]===0)
{
return false;
}
}
return true;
}
i know this is not the best wayto solve .Is there a better way to do this?i don't like that long if statement in my code.i have seen other SO links-link1,link2 but none of them seemed to solve my query. any kind of help is highly appreciated.
P.S. this code is not working for some true cases even.
o = new Object();
o.prop = 'exist';
if(o.hasOwnProperty('prop')){
if(o['prop']){
alert('good value')
}
}
https://stackoverflow.com/a/6003920/1074179
this is what i was looking for and absolutely logical-
for(var i in array){
if((prop in array[i])&& Boolean(array[i][prop]))
{
//do something
}
}
the Boolean() function is something which made my day. Learn more at this link.
Look at the below example.
let the json object be
var a = { obj1:"a",obj2:"b"}
to check if an object exists,you can use hasOwnProperty() method.
a.hasOwnProperty("obj2") //this will return true
a.hasOwnProperty("obj3") // this will return false
to check the value of an object
if(a["obj1"] && a["obj1"]!="" && a["obj"]!=0){
//place your logic here
}
I need to do an assertion to check if an element is present inside 'elements.all'.
My first idea is to run a for loop and put an expect inside. Not a great idea because it is checking every single items on list. So if I have 30 items, I might end up with 29 fails.
element.all(by.css(element)).then(function(itemList) {
console.log("Total values in dropdown are: " + itemList.length);
for (i = 0; i < itemList.length; i++) {
itemList[i].getText().then(function(text) {
console.log(text);
expect(text).toEqual('whatever-i-need-to-assert');
});
};
});
In order to solve this problem, I nest an IF statement that will 'pre-check' for a string match. Another bad idea because if there is no match, my expect will never run, thus, giving me a false pass:
element.all(by.css(".item a.gc-exercises-link")).then(function(itemList) {
console.log("Total values in dropdown are: " + itemList.length);
for (i = 0; i < itemList.length; i++) {
itemList[i].getText().then(function(text) {
console.log(text);
if (text == 'BOATLIFT-EXERCISE') {
console.log('Match');
expect(text).toEqual('BOATLIFT-EXERCISE');
} else {
console.log('No Match');
};
});
};
});
Clearly, I am in the wrong path here. Can someone give me an idea how to properly expect for a 'Text' when using element.all. I just need to prove that a text is present on the said list.
Thanks!
Here is an example to check that there is a link with the text "Terms" in a page :
browser.get('https://www.google.co.uk/');
expect(element.all(by.css('a')).getText()).toContain('Terms');
Note that for each element, protractor needs to interogate the browser, which could be slow especially if there is a lot of elements.
A quicker solution would be to check that at least one element is present with a XPath including the expected text:
browser.get('https://www.google.co.uk/');
expect(element.all(by.xpath("//a[text()='Terms']")).count()).toBeGreaterThan(0);
If you just want to check it's present (and other list item's won't interfere), you could call .getText() on the array after element.all, before .then and use toContain()
element.all(by.css(".item a.gc-exercises-link")).getText().then(function(itemList) {
expect(itemList).toContain('some text');
};
Or if you know the index:
element.all(by.css(".item a.gc-exercises-link")).getText().then(function(itemList) {
expect(itemList[3]).toEqual('some text');
}
As a side note: you can use .each() instead of creating a for loop https://angular.github.io/protractor/#/api?view=ElementArrayFinder.prototype.each
You can use filter function.
$$("span").filter(function(elem,index){
return elem.getText().then(function(txt){
return txt === 'text to compare';
});
}).then(function(eleList){ // you get the list of elements containing the text here
console.log(eleList.length);
});
As part of a xtype combo, I would like to know if the layer I choose in my simple data store (represented by this.getValue()) is present in the map layers. So if it does, A should occur, and B if it does not. The problem is that myLayer variable seems to be unrecognized, even though Opera Dragonify throws no error at all. Where would be the error?
listeners: {
'select': function(combo, record) {
for(var i = 0; i < mapPanel.map.length; i++) {
var myLayer = mapPanel.map.layers[i].name;
if (myLayer == this.getValue()) {
// do A here...
} else {
// do B here...
}
}
}
}
Thanks for any pointers,
I think the problem is that you are using this.getValue() instead of using combo.getValue().
I don't know how your app is set but it's usually a better idea to use the first parameter of your listener instead of the keywork this in order to avoid scope issues.
Hope this helps
#Guilherme Lopes Thanks for that, but the solution was this: mapPanel.map.layers.length instead of mapPanel.map.length.
