as you see in the code below. I have a jQuery function called externally.
I don't understand why I can't get the class name, I get an alert with "undefined", I was expecting "classifyClass" instead, can you help? Thank you.
<html>
<head>
<meta charset="utf-8">
<title>parent</title>
<script src="./js/jquery-1.4.2.min.js"></script>
<script>
function classify() {
//some jquery stuff here alredy, and it works...
//now I want to get/set the parent class, but not working (getting an alert with written "undefined", why?
var myclass = $(this).parent().attr('class');
alert(myclass);
}
</script>
</head>
<body>
<div class="pos">
<div class="classifyClass">
<div style="width:50px;height:50px;background-color:red;" onclick="javascript:classify();return false;"></div>
<div style="width:50px;height:50px;background-color:green;" onclick="javascript:classify();return false;"></div>
</div>
</div>
<div id="feedback"></div>
</body>
</html>
P.s. I don't want to use the jquery selector I need to call the function like that as I'm pass开发者_运维技巧ing some asp.net parameters, I simplified here the example to focus on the main problem. Thank you.
In your current context this refers to the window object. You either need to pass this, like this:
onclick="return classify(this);"
With matching script:
function classify(elem) {
//some jquery stuff here alredy, and it works...
var myclass = $(elem).parent().attr('class');
alert(myclass);
return false;
}
Or (better), binding unobtrusively (using your current function, this will work), like this:
$(".classifyClass > div").click(classify);
