I have the following `HTML` **HTML**

I can sort my `

` elements but I need know the position of a specific `

` that I sort. **Exemple** If I put in my console `$("#sortable").find("li").size()`, I have the return of the numbers of `

` are in my `

`, 6 in this case. But how can I know the position of a specific `
• ` like, the `
• ` with the `id` 373231, where this `
• ` are inside my `
  ` ? The return that I want is the number 5, because he is the fifth `
  • ` element in my `
    ` **UPdate** My function $(function () { $("#sortable").sortable({ stop: function (event, ui) { debugger; // Getting a WRONG Position alert($(this).index()); } }); $("#sortable").on("sortstop", function (event, ui) { // Getting a WRONG Position alert($(this).index()); }); $("#sortable").disableSelection(); });
