hi everyone.I learning elixir and phoenix.thanks in advance.
the code in oninput is for validating key input for number only.its does not work.why?
<%= text_input f, :spent, maxlength: "2", size: "2", oninput: "this.value=this.value.replace(/(?![0-9]|\.)./gmi,'')" %>
this one working but i had no idea how to bind it to the :spent
<input class="text-xl" maxlength="2" size="2" oninput="this.value=this.value.replace(/(?![0-9]|\.)./gmi,'')"></input>
