Question: ```
<div class='hide'>A</div>
<div class='hide'>B</div>
<div class='hide' id='1'>C</div>

```

I have a function called showOne which should hide all elements and then show the one with id='1'.

```
function showOne(id) {
// Hide all elements with class = 'hide'
$('#'+id).show();
}

```

How do I hide all elements with class = 'hide' in jquery?

Answer: 
I'm almost ashamed of how easy the solution was and that I found it just after writing the question. Just:

```
$('.hide').hide();

```
You can hide all components with class as hide using **.** 
 $('.hide').hide();
