Hello everyone I’m trying to run multiple javascripts and use AND statement. When user click an option which has value=”1986″ and click other option which has value=”3″, some text will appear. I have used AND statement in if statement but it doesn’t work. Here is my code :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script></script>
<script type="text/javascript">
$(document).ready(function() {
$('#main').on('change', '.select-box', function() {
if ($(".select-box option[value='3']").attr('selected') & $(".select-box option[value='1986']").attr('selected')) {
$('#demo').html("Hello World");
}
});
});
</script>
<script type="text/javascript">
var x="",i;
for(i=1986;i<2013;i++)
{
x=x + "<option value='"+i+"'> " + i + "</option>";
}
$(document).ready(function() {
document.getElementById("demo2").innerHTML="<select class='select-box'>"+x+"</select>";
});
</script>
</head>
<body>
<p id="demo2"></p>
<div id="main">
<select class="select-box">
<option value="0">alert</option>
<option value="1">alert to</option>
<option value="2">no alert</option>
<option value="3">best alert</option>
</select>

<div id="demo"></div>
</div>
</body>
