my pages uses lots of ng-repeat to generate table rows. If there is no data in an json array, there would be an empty table. I'm trying to skip generating table rather than an generate an empty one.
To do that, I need to check if the array length is 0. In js I can get array length using its length property:
$scope.data.errors.length === 0
But I can't use it in angular watcher, the following has no output
{{data.errors.length}}
And data.errors.length === 0gives false.
So is there a way to get json array length in angular?
You can use ng-show Ex.
<div ng-show=data.errors> your html </div>
Or you can use ng-repeat following code will execute if there is an error
<div ng-repeat="error in data.errors"></div>

im new to js, have two question about how to parse a csv, i have a simple csv with two column, column1:'user', column2:'amount'
how can i get one array with all the 'user' column value and one
array with all the 'amount' column value?
And can i loop trough the rows and use index to get the
value of the two column? something like csv['amount'][0] or csv[0][1] or something like this?
ty.
First, declare 2 arrays, one for user, one for amount.
And then read this post to know how to read a file line by line.
After that, read this post to know how to split a string with a comma separator.
Finally, use the array.push() method to push the data into an array.
I load a json file to a javascript object whith jquery.
I get an array object (each row is a json object).
Currently, I display javascript object content to a html table with a for on each row of the obect.
Is it possible to directly filter my javascript array object depending on the columns conditions and not with a for command again?
Thanks a lot.
Theo.
probably this can help you with little change
const result = words.filter(word => word.length > 6);
Hi I am using AngularJS on a WordPress site and when displaying custom field values using Angular tags in my partials HTML file such as {{post.manualest}}, it displays as ["1,500,000"]
How can I remove [" "] so that it shows only 1,500,000?
Since {{post.manualest}} contains an array you need ng-repeat
<p ng-repeat="tag in post.manualest">{{tag}}</p>
The ngRepeat directive instantiates a template once per item from
a collection. Each template instance gets its own scope, where the
given loop variable is set to the current collection item, and $index
is set to the item index or key.
https://docs.angularjs.org/api/ng/directive/ngRepeat
The data you received (in manualest key) is an Array. So either you can use the ng-repeat as #Vicky suggested or you can simply write in your HTML:
{{post.manualest[0]}}
Edit: Like #FuzzyTree already mentioned in the comment.
This is javascript array
var data =['athar','naveed','123','abx'];
Now I want to access this array in code behind array or list variable. Don't want to use Hidden field.
If you want to use in anyother javascript function,you can simply use data[0] to access first element i.e.,athar.
data.length will give you the count of values present in the array.
I'd like to know how to get the values from a bi-dimensional array in Selenium.
I have a file called resources.js, where I create the arrays and access it in Selenium, here is the array:
This array must have 4 columns and n numbers of lines.
How do I store the values of the 4 columns in variables? (it would be good to do it in a WHILE loop, to store/show the values from all rows if possible)
This is what I've tried and failed miserably:
This seems like more of a JavaScript question than a Selenium question. The way to access multi-dimensional arrays in JS is like: Test[array_index][item_in_array_index].
So if you were trying to get the value 'name1', it would be Test[0][0].
