I'm trying to figure out how to call a Javascript function only when a checkbox is NOT checked.
Here is my checkbox:
<input type="checkbox" id="icd" name="icd" value="icd" />
Here is the name of the function:
planhide();

document.getElementById('icd').onchange = function() {
if ( document.getElementById('icd').checked === false ) {
planhide();
}
};

Include onchange option in the input tag and then add an intermediate function that checks and calls planhide() accordingly as follows:
<input type="checkbox" id="icd" name="icd" value="icd" onchange=check()/>
Then define the check() to do check the state and call the function as follows:
function check()
{
if(document.getElementById("icd").checked==false)
planhide();
}
Also instead of onchange you can also use onclick on the submit button option to call the check() function as like follows:
<input type="button" onclick=check()/>

$(document).ready(function () {
$('#icd').change(function () {
if (!this.checked) {
planhide();
}
});
});

You should add some form of explanation, try and avoid code only answers as they are of limited use to the OP and future visitors
just register an onchange handler on your input, check the 'checked' property when the handler is call, and call the method if checked is false.
