JQuery can't get input value on element

All I'm trying to do is get the

val()
of an Text Input. Here is an example.

I don't know if external links are allowed so I will also paste it here :

<div class="input-group">
<input type="text" id="#test" class="form-control" aria-label="..." style='border-radius:4px;'>
</div>

<script>
// Always shows up as undefined..not "".
console.log($("#test").val());
</script>


Does anyone know why I cannot get the value of this element?

Answer

You have to remove the # sign from the id attribute :

<input type="text" id="#test" class="form-control" aria-label="..."  ..
