<div class="has_many_fields_row countable" id="location_account_associations_attributes_0">

                <ul class="grid grid--no-gutters">
                    <li class="grid__6 grid__x--show">
                        Account Thing
                        <input id="location_account_associations_attributes_0_ab_account_id" name="location[account_associations_attributes][0][ab_account_id]" type="hidden" value="42" />
                    </li>
                    <li class="grid__5">
                        <select class="js-select2-combobox" id="location_account_associations_attributes_0_account_id" name="location[account_associations_attributes][0][account_id]" placeholder=" " reflection="#&lt;ActiveRecord::Reflection::AssociationReflection:0x012fb5asd200e8&gt;">
                            <option value=""></option>
                            <option value="1">Orange</option>
                            <option value="2">Apple</option>
                        </select>
                    </li>
                </ul>
            </div>
        </div>
    </div>
</div>

我尝试了多种不同的方法来选择"橙色".请注意,当按下某个键击时,此jQuery会执行.此外,由于多种原因,HTML无法编辑.只能更改jQuery.

使用Javascript/jQuery的:

(function() {
    $(document).on("keydown", function(e) {

        // ignore unless CTRL + ALT/COMMAND + N was pressed
        if (!(e.keyCode == 78 && e.ctrlKey && e.altKey )) return

        jQuery('[name*="[account_associations_attributes][0]').select2("val",1);
        jQuery('[name*="[account_associations_attributes][0]').select2("val","Orange");
     })
 }())

Answer 1

结束找到解决方案.

jQuery('[name*="[account_associations_attributes][0]"]').select2('val', '1')
