Hi all ,
I am trying to place a button under another button using jquery but it is staying in its place.Knowing that when alerting its top and left they are giving me correct values as i want.So how to fix it ?
Here is the code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Untitled Page</title>
<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
</head>
<body>
<form action="">
<input type="button" id="placeit" value="placeit" name="btn2" />
<input id="btn1" type="button" name="btn1" value="button" />
<p>
</p>
</form>
<script type="text/javascript">
var p = $("#btn1");
var position = p.position();
var place = document.getElementById("placeit");
place.top = position.top + 30;
place.left = position.left;
alert(place.top);
alert(place.left);
$("p:last").text("left: " + position.left + ", top: " + position.top);
</script>
</body>
</html>
推荐答案
(#btn1"); var position = p.position(); var place = document.getElementById("placeit"); place.top = position.top + 30; place.left = position.left; alert(place.top); alert(place.left);
("#btn1"); var position = p.position(); var place = document.getElementById("placeit"); place.top = position.top + 30; place.left = position.left; alert(place.top); alert(place.left);
("p:last").text("left:" + position.left +，top:" + position.top); < /script > < /body > < /html >
("p:last").text("left: " + position.left + ", top: " + position.top); </script> </body> </html>
