Jquery Loop , condition and assigning to variable?

Question

I have an array after dd() in php it show like this array:

1 [▼0 => "1,18,187,188,189,190,191,192,193,194,195,196,197,198,199,200,201,202,203,204,205,206,207,208,209,210,211,212,19,20,21,22,23,24"]

now I want to loop the array and pass only those values which are more than 200. Here is the code

 $('#btnSave').on('click', function () {
   var checkedIds = mytree.getCheckedNodes();
   $('#userData').val(checkedIds);
 });

where #userData is a hidden field and checkedIds has the above values.

How to loop and make a condition to assign only the desired values to #userData

Your array has only one element and it is a comma delimited string. There are plenty of resources that explain how to turn a string like that into an actual array. — El_Vanja

Please do not tag questions with improper tags just to get them more available. php tag is redundant here. — biesior

@biesior I'd beg to differ. The source of the data is an array coming from PHP. Reformatting data into a desired shape is best done at the source whenever possible, to relieve the client of any extra work. — El_Vanja

Ismail, I can advise you to have a look at explode and array_filter. — El_Vanja

In PHP, instead of using dd() encode the array into JSON and put it into an element's data attribute (with proper escaping): <a data-array="<?php escape(json_encode($array))">...</a>. Then in js, you can decode the JSON again: const array = JSON.parse(element.getAttribute('data-array')).

Putting a value into an otherwise irrelevant DOM element does not seem a good way to go about this. You can put it directly in a js variable const array = JSON.parse("<?php escale(json_encode($array,....
