Rails: Set multiple values for hidden_input_field using Javascript
I am using Rails 5 and trying to implement multiple delete functionality. Here is the form:
<%= form_tag destroy_multiple_scan_assets_path, method: :delete do %>
<%= hidden_field_tag :asset_ids, nil, multiple: true %>
<%= submit_tag 'Delete', class: 'btn btn-danger' %>
<% end %>
Now the hidden field value is to be set using javascript based on some checked boxes:
$('input.btn-danger').click(function() {
var selected_asset_elements = $('input.form-check-input:checkbox:checked');
var selected_assets_count = selected_asset_elements.length
if (selected_assets_count == 0) {
alert('Please select an asset to delete.')
return false;
} else if (confirm(`Are you sure, you want to delete ${selected_assets_count} assets?`)) {
selected_asset_elements.each(function () {
// Push $(this).val() in to the hidden filed value
});
} else {
return false
}
});
How do I set hidden field's value so that it's interpreted by rails as:
Parameters: {"asset_ids"=>["1", "2", "3", "4"]}

You can't do that using a single hidden field, but you can have that result if you add one hidden field with name asset_ids
for each id. That's how rails knows it has to parse the params as an array.
selected_asset_elements.each(function (el) {
field = document.createElement('INPUT');
field.type = 'hidden';
field.name = 'asset_ids';
field.value = el.id; #something like this
your_form.append(field);
});
By the way, multiple
is not a valid option for a hidden field, it just accepts a string value.
