使Div标签可点击

Question

Hi Below code gives me the list of messages in table row format and i want to make each row as clickable. I have tried every suggestion in SO but could not make it work.
As i could not make whole tr clickable, i made i.reason field as clickable as temprorary solution.

<% if @notifyCount > 0 %>
<table class="table table-hover table-condensed">
<% @notify.each do |i| %>
<tr class="notifyTable" id= "<%=i.id %>">
 <td class="myWidth concat"> 
    <%= image_tag "#{i.incident_image}", style: "height:45px; width:45px; float:left; margin: 0 8px 0 0" %> <b> <%= i.sender.first_name + ' ' + i.sender.last_name %> </b> <br> 
    <div> <%= link_to truncate(i.reason.capitalize, length: 50), message_member_path(id: i.id), style: "text-decoration:none" %> </div>
 </td>
</tr>
<%end%>
</table>
<%else%>
<p style="opacity:0.7;text-align:center;margin-top:5px"> No Unread Messages ...</p>
<%end%>

JS

You'll have to use Javascript to make this work

Javascript (and JQuery) basically works on the front-end of the browser (inside the DOM - Document Object Model ) to bind events to elements on the page.

Here's how you'd made a div "clickable" using JQuery:

#app/assets/javascripts/application.js
$(document).on("click", ".div", function() {
   // Your Action Here
});

In regards to the specifics of your question, you may need to look at using the following code:

#app/assets/javascripts/application.js
$(document).on("click", ".notifyTable", function(){
   alert("Row is clicked");
});

This will allow you to capture the click event. If you want to then perform things with that click, you'll be best adding data attributes to your row , like so:

<tr class="notifyTable" id= "<%=i.id %>" data-link="http://google.com">

This would allow you to do this:

#app/assets/javascripts/application.js
$(document).on("click", ".notifyTable", function(){
   window.location.href = $(this).data("link")
});
