Display text with a checkbox

Question

I would like to display some text (help) when the checkbox (?) is checked: but I can't do it ... Why? This is my code:

- - - HTML

<input type="checkbox" id="what" name="help" value="yes" onclick="aide()"/>
<label for="what"> ? </label>
<div id="info">Some text to display for helping</div>

- - - JAVASCRIPT

function aide() {
let what=document.getElementById("what");
let info=document.getElementById("info");

if (what.cheked) {
info.style.display="inherit";

}
else {
info.style.display="none";
};
}

- - - Thank for helping

Answer 1

You would just do the same thing. If you mean how you would check which box is checked, that's a little different, because with checkboxes, all of them can be checked, so you have to validate every case.

if (a.checked && b.checked)
else if (a.checked)
else if (b.checked)
else // none are checked

Answer 2

cheked needs to be spelled properly. Add a 'c': what.checked

This is why using a text editor with intellisense or autocompletion is really helpful.

Answer 3

I found the answer:

- - - HTML
<input type="checkbox" id="aide" onclick="aide()">
<label for="aide">?</label>
<div id="info">Some text</div>

- - -JAVASCRIPT

function aide() {
var aide = document.getElementById("aide");
var info = document.getElementById("info");
if (aide.checked == true){
info.style.display = "block";
} else {
info.style.display = "none";
}
}

But... If i have more that one check box, how i can do it? With the class??
