Question

I have list view in jQuery Mobile web app this list view is made of elements like this:

<li id='search_r'>
    <a href='#' id='$id' class='s_result'></a>
</li>
<li id='search_r'>
    <a href='#' id='$id' class='s_result'></a>
</li>

Number of element depends on number of search results, its not only these two.
When I click on element in list view, in this case:

<li></li>

I need 2 things to happen, one is to assign the ‘id’ attr from “a” tag inside this specific “li” tag (the clicked one), to the global variable I have called ‘search_r’. The click event works fine, but to get attribute from “a” tag I can’t manage to do.

Here is my js:

$("#cc_page").ready(function(){
  $("#search_r").live('click', function(){
      search_r = $(this).attr('id');
      window.location.href = "http://imes.********.com/app/userpanel.html#sfpp_page";
  });
});

I know “this” is not solution. I’m really new to js so that’s why I’m asking such an ridiculous questions 🙂

The first problem you’ve got is duplicate search_r id attributes, which is invalid. These should be changed to classes. Also, you should be using on() with a delegate handler, as live() has been removed from the latest version of jQuery. Try this:

<li class='search_r'>
    <a href='#' id='$id' class='s_result'></a>
</li>
<li class='search_r'>
    <a href='#' id='$id' class='s_result'></a>
</li>

$("#cc_page").on('click', '.search_r', function(){
    var search_r = $('a', this).attr('id');
    console.log(search_r); // just to check it works

    // I assume this is just for testing, otherwise leaving the page 
    // immediately on click renders getting the id completely moot.
    //window.location.href = "http://imes.********.com/app/userpanel.html#sfpp_page";
});

I also assume the $id in your HTML is from some form of templating engine which gets interpreted? If not, those will also need to be made unique.
