我将尝试使用jquery设置select2的值。这可能是一个重复的问题,但我在这里已经阅读了30个不同的回答,没有找到解决我的问题的方法。

HTML代码:
<div class="has_many_fields" data-required-has-many-fields-rows="1" id="location_account_associations"><input id="location_account_associations_attributes_0__destroy" name="location[account_associations_attributes][0][_destroy]" type="hidden" value="false" />
<div class="has_many_fields_row countable" id="location_account_associations_attributes_0">
<div class="form__row form__row--spreadsheet">
<div class="form__row__body">
<div class="form__row__field-wrapper">
<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="#<ActiveRecord::Reflection::AssociationReflection:0x012fb5asd200e8>">
<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“Orange”。请注意,在按下某个按键时执行此jQuery。另外,由于多种原因,HTML不能编辑。只有jQuery可以更改。
Javascript / jQuery:
(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");
})
}())
select2('val', ['1','2','5'])
