is :checked not working while using Jquery 1.7

Look at this simple code

html

<input type="checkbox" id="check" >&nbsp;<span id="rm">Remember
me</span> <span id="ok">Okay!</span>

css

#ok{
position:absolute;
font:italic bold 14px century;
color:green;
margin-left:3px;
margin-top:2px;
display:inline-block;
opacity:0;
}

Jquery

if($('#check').is(":checked"))
    {
    $("#ok").css("opacity",1);
    }

No it is working, but your code is not for those 2 reasons.

  1. You misspelled id on the DOM tag.

  2. You have no event listener. You code is running on window load and doesnt check after that. You need to add a binding like change.

Here the proof : http://jsfiddle.net/4Hf9T/13/

$('#check').change(function(){
    if($(this).is(":checked"))
        {
        $("#ok").css("opacity",1);
        }
    else if(!$(this).is(":checked")) // "if" not needed, just showing that you can check if it is not checked.
        {
        $("#ok").css("opacity",0);
        }
})

This is a working jsfiddle: http://jsfiddle.net/4Hf9T/14/

<input type="checkbox" id="check">&nbsp;<span id="rm">Remember me</span>

<span id="ok">Okay!</span>

JS code:

$('#check').on('change',function(){
    if(this.checked)
        $("#ok").css("opacity", 1);
    else 
        $("#ok").css("opacity", 0);
});

This question has been asked before, and someone posted a detailed answer: https://stackoverflow.com/a/2204275/1745452

The jQuery API Documentation states that it should be working since the first verion. Perhaps you misspelled the selectors?

Your checkbox was not checked on page load. although you can do something like this -

$("#check").on('change', function () {
    if ($(this).is(":checked")) {
        $("#ok").css("opacity", 1);
    }
    else{
     $("#ok").css("opacity", 0);
    }
});
