Get array of text values using selector instead of iterating?
(7 answers)
Closed 9 years ago.
I have html with multiple things classed .text. I the perform
console.log($(whatever).find('.foo').text());
The result is a textstring with all the contents in it. Can I save it to an array instead somehow?
You can use the map method to get this done
var textArray = $(whatever).find('.foo').map(function() {
return $(this).text();
}).get();
This will get you an array.. If you want to display it as a string then just use join along with it.
Check Fiddle
var arr = [];
$(whatever).find('.foo').each(function() {
arr.push($(this).text());
});

Closed 2 months ago.
I have an array which has some empty items.
const array = ["a","","c","","e","f","g"]
I am trying to eliminate empty items and leave only the items having string. I mean manipulating the array as:
array = ["a","c","e","f","g"]
There are many alternative like array.map, array.filter, array.slice, array.splice.. What is the most costless and recommended way of doing this?
As far as I know most cost effective way is to use the array filter method:
const array = ["a","","c","","e","f","g"];
const results = array.filter(element => {
return element !== '';
});
console.log(results);

How to retrieve checkboxes values in jQuery
(14 answers)
Closed 9 years ago.
I am looking to get all checkboxes' VALUE which have been selected through jQuery.
You want the :checkbox:checked selector and map to create an array of the values:
var checkedValues = $('input:checkbox:checked').map(function() {
return this.value;
}).get();
If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')
- Update -
If you don't need IE support then you can now make the map() call more succinct by using an arrow function:
var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();
