In this code jquery get the data back from php and i would like to get jquery explode one of the variable where multiple auto are stored and finally get the specific checkbox checked
json_reponse_from_PHP: "auto1; auto3; auto4".
$(document).on("click", "#update", function(e) {
e.preventDefault();
var datas = 'pg/post.php';
$.getJSON(datas, function(data) {
$.each(data, function( key, value ) {
$('input[name=' + key + '], select[name=' + key + '], textarea[name=' + key + ']').val(value);
});
});
});

<input type="text" name="name" value="" />
<input type="text" name="name" value="" />
</div>
See example:
<input type="checkbox" name="auto[]" checked="checked" value="auto1" />
<input type="checkbox" name="auto[]" value="auto2" />
<input type="checkbox" name="auto[]" checked="checked" value="auto3" />
<input type="checkbox" name="auto[]" checked="checked" value="auto4" />
<input type="checkbox" name="auto[]" value="auto5" />
<input type="checkbox" name="auto[]" value="auto6" />
Can you help me to find

Answer 1

If you want to check a checkbox you don't use val() you use prop('checked', true)
Since you have array naming on elements you can't match the specific name so you will need to use the returned value to help target the checkboxes.
Also what you are sending from server doesn't match the names anyway.
$.each(data.split(';'), function(_, val ) {
$(':input[value=' + val +']').prop('checked',true);
});
It makes no sense either not to send array from server instead of json_encoding a delimited string in your php
