我使用Simple Form Gem在我的rails应用程序中创建了一个表单。 14个字段中的3个是文本区域输入字段(字段4,5和6)。但是,当显示表单时,会出现一些意外行为;大多数字段按预期垂直顺序显示,但3个文本区域字段全部显示在屏幕中间,实际上部分覆盖字段2和3.宽度也大于屏幕宽度,这会导致滚动条出现在页面底部。它们应该是小文本区域输入字段,每个字段都按照其他输入字段的正确顺序。下面我列出了解决问题的尝试。
我正在使用rails 5.1.5和ruby 2.2.6。另外我使用的是Bootstrap 3。
这是形式partial _form.html.erb。
<%= simple_form_for(@questionnaire) do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<div class="form-inputs">
<%= f.input :name %>
<%= f.input :dob %>
<%= f.input :q1 %>
<%= f.input :q2 %>
<%= f.input :q3 %>
#3 fields below are causing the problems (q4, q5, q6)
<%= f.input :q4 %>
<%= f.input :q5 %>
<%= f.input :q6 %>
<%= f.input :q7 %>
<%= f.input :q8 %>
<%= f.input :q9 %>
<%= f.input :q10 %>
<%= f.input :q11 %>
<%= f.input :q12 %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
schema.rb
ActiveRecord::Schema.define(version: 20180516082217) do
create_table "questionnaires", force: :cascade do |t|
t.string "name"
t.date "dob"
t.string "q1"
t.string "q2"
t.string "q3"
t.text "q4"
t.text "q5"
t.text "q6"
t.boolean "q7"
t.boolean "q8"
t.boolean "q9"
t.integer "q10"
t.integer "q11"
t.integer "q12"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
end
我尝试过许多方法来尝试改变文本区域的大小和位置。我设法使用
改变高度<%= f.input :q4, as: :text, input_html: {rows: 10, cols: 10} %>
然而,这对宽度或位置没有影响,但确实改变了高度 我还尝试添加自己的css将视图更改为:
<%= simple_form_for(@questionnaire) do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<div class="form-inputs">
<%= f.input :name %>
<%= f.input :dob %>
<%= f.input :q1 %>
<%= f.input :q2 %>
<%= f.input :q3 %>
</div>
<div class="test">
<%= f.input :q4 %>
<%= f.input :q5 %>
<%= f.input :q6 %>
</div>
<div class="form-inputs">
<%= f.input :q7 %>
<%= f.input :q8 %>
<%= f.input :q9 %>
<%= f.input :q10 %>
<%= f.input :q11 %>
<%= f.input :q12 %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
和问卷调查.scss
.test
{
width: 300px;
height: auto;
}
我通过更改
部分解决了定位问题<%= f.input :q4 %>
为:
<%= f.input :q4, as: :string %>
这解决了定位问题,并且所有字段都处于正确的顺序和位置,但现在输入是字符串输入(单行),我更喜欢为这些字段输入文本。什么可能导致text_area输入出现在屏幕中间而不响应我所做的更改?我现在想不出更多的解决方案,所以会欣赏任何新的观点。

答案 0 :(得分:0)
右键单击网页并使用&#34;检查&#34;函数为了看到HTML我能够看到text-area元素继承了一个名为&#34; .text&#34;的css类。这里的财产&#34;位置&#34;被设定为&#34;绝对&#34; (或相对于包含块设置)。将此属性更改为&#34; static&#34;解决了这个问题。
将我自己的.text css类添加到我的custom.css.scss文件中,如下所示,覆盖了从该文件中获取此属性的.text css类
.text {
position: static;
}
