Question

我正在使用狂欢引擎，并希望更改所有选择标记样式。所以我想在这个选择中添加一个类。我在rails 3.2和ruby 2.0.0-p0工作。该文件位于html.erb

<%= select "search", filter[:scope], labels.insert(0, [filter_title(filter[:name]), nil]), selected: params[:search][filter[:scope]] %>

我试过了

<%= select "search", filter[:scope], labels.insert(0, [filter_title(filter[:name]), nil]), selected: params[:search][filter[:scope]], {:class => "select2"} %>

这打破_filters.html.erb:10: syntax error, unexpected ')', expecting => ...cope]], {:class => "select2"} );@output_buffer.safe_concat('

<%= select "search", filter[:scope], labels.insert(0, [filter_title(filter[:name]), nil]), selected: params[:search][filter[:scope]], :class => "select2" %>

这会运行但不会将类添加到选择标记

<%= select( filter[:scope], labels.insert(0, [filter_title(filter[:name]), nil]), selected: params[:search][filter[:scope]], {:prompt => "search"}, {:class => "select2"} )%>

这打破_filters.html.erb:10: syntax error, unexpected ',', expecting => ...scope]], {:prompt => "search"}, {:class => "select2"}));@out...

我已经FormOptionsHelper了{{1}}，但似乎我正在使用选择标记的旧语法rails。我无法想象任何人有同样的问题吗？

Answer 1

您的选择应如下所示： -

<%= select "search", filter[:scope], labels, {selected: params[:search][filter[:scope]]}, {class: "class"} %>

或具体

{selected: params[:search][filter[:scope]]}, {class: "class"}这是最后一个参数

向Rails中添加一个类选择
