[英]AngularJS - Add a drop down menu feature into a HTML table using Jquery
[英]Rails 4 / JS / HTML Unable to add a drop down menu so it creates a filter for a html table
試圖弄清楚如何添加一個下拉菜單,以便為我的html表創建一個包含產品列表的過濾器。 使用我不存在的Javascript技能和Google,我遇到了這段有趣的代碼
http://www.bclittleleague.bc.ca/Baseball/Javascript/TableFilter_EN/examples_EN.htm#tbl2 (表格2)
<script language="javascript" type="text/javascript">
//<![CDATA[
var table2_Props = {
col_0: "select",
col_5: "none",
display_all_text: " [ Show all ] ",
sort_select: true
};
setFilterGrid( "table2",table2_Props );
//]]>
</script>
我已將此添加到我的listing.js.coffee文件中
//<![CDATA[
var table2_Props = {
col_0: "select",
col_5: "none",
display_all_text: " [ Show all ] ",
sort_select: true
};
setFilterGrid( "table2",table2_Props );
//]]>
listings.html.erb
<h1>Listing listings</h1>
<table class="table">
<thead>
<tr>
<th>Name</th>
<th>Description</th>
<th>Price</th>
<th></th>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
<% @listings.each do |listing| %>
<tr>
<td><%= listing.name %></td>
<td><%= listing.description %></td>
<td><%= listing.price %></td>
<td><%= link_to 'Show', listing %></td>
<td><%= link_to 'Edit', edit_listing_path(listing) %></td>
<td><%= link_to 'Destroy', listing, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Listing', new_listing_path %>
但是當我編譯時,我ExecJS::RuntimeError in Listings#index. SyntaxError: [stdin]:2:2: reserved word "var" in Desktop/Rails/fooddemo/app/assets/javascripts/listings.js.coffee)
得到ExecJS::RuntimeError in Listings#index. SyntaxError: [stdin]:2:2: reserved word "var" in Desktop/Rails/fooddemo/app/assets/javascripts/listings.js.coffee)
ExecJS::RuntimeError in Listings#index. SyntaxError: [stdin]:2:2: reserved word "var" in Desktop/Rails/fooddemo/app/assets/javascripts/listings.js.coffee)
Fooddemo <%= stylesheet_link_tag“ application”,媒體:“所有”,“ data-turbolinks-track” =>正確%> <%= javascript_include_tag“ application”,“ data-turbolinks-track” =>正確%> <-錯誤 <%= csrf_meta_tags%>
mu是正確的,問題出在listing.js.coffee文件中。 var
在coffeescript之后導致此錯誤。
有兩種解決方法:
1)將您的代碼轉換為coffeescript。 http://js2coffee.org/上有一個有用的轉換器,它提供以下信息:
table2_Props = col_0: "select" col_5: "none" display_all_text: " [ Show all ] " sort_select: true setFilterGrid "table2", table2_Props
如果將其粘貼到其中,則需要注意所有間距都正確維護。
2)將文件名更改為listing.js,它將把代碼視為純JavaScript。
