我已經HAML像這樣:設定輸入值 - 問題與HAML
.form-group
.col-sm-3.control-label
= f.label :trial, "Free Trial Offered"
%span.tipsy{"data-toggle" => "tooltip", title: t("campaigns.services_form_free_trial_help")}
= link_to content_tag(:i, "", class: 'glyphicon glyphicon-question-sign'), '#'
.col-sm-4
= f.select :trial, [['Yes', 'true'], ['No', 'false']], {}, class: 'selectpicker mandatory'
這將創建下列HTML:
<div class="form-group">
<div class="col-sm-3 control-label">
<label for="campaign_trial">Free Trial Offered</label>
<span class="tipsy" data-toggle="tooltip" title="" data-original-title="Select whether or not you wish to offer a free trial with your service.">
<a href="#"><i class="glyphicon glyphicon-question-sign"></i></a>
</span>
</div>
<div class="col-sm-4">
<select class="selectpicker mandatory" id="campaign_trial" name="campaign[trial]" style="display: none;">
<option value="true" selected="selected">Yes</option>
<option value="false">No</option>
</select>
<div class="btn-group bootstrap-select mandatory">
<button type="button" class="btn dropdown-toggle" data-toggle="dropdown" data-id="campaign_trial" data-original-title="" title="">
<span class="filter-option pull-left">
Yes
</span>
<span class="caret">
</span>
</button>
<ul class="dropdown-menu" role="menu" style="max-height: 89px; overflow-y: auto; min-height: 0px;">
<li rel="0" class="selected">
<a tabindex="0" class="">
<span class="text">
Yes
</span>
<i class="icon-ok check-mark"></i>
</a>
</li>
<li rel="1" class="">
<a tabindex="0" class="">
<span class="text">
No
</span>
<i class="icon-ok check-mark"></i>
</a>
</li>
</ul>
</div>
</div>
</div>
正如你不能簡單的下拉列表中創建的,但而是一個複雜的按鈕和下拉組合。我希望能夠設置上述值的另一個輸入字段然而,典型的方法,如jQuery的更改處理程序不工作,因爲我不能使用id等來確定何時下拉更改。任何人都可以建議我如何實現這一目標。
我也在考慮將兩個模型屬性與一個下拉列表關聯,以便根據一個選擇將它們設置爲相同的值,但不確定這是否可能。
