jQuery让控件左右移动的三种实现方法

方法一
【注】需把控件的 CSS 的 position 属性设置为 relative 或 absolute。


代码如下:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script language="javascript">
$(document).ready(function(){
$("#right1").click(function(){
$(".block1").animate({left: '+=50px'}, "slow");
});
$("#left1").click(function(){
$(".block1").animate({left: '-=50px'}, "slow");
});
});
</script>

方法二


代码如下:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script language="javascript">
$(document).ready(function(){
$("#right2").click(function(){
$(".block2").css("margin-left","+=50px");
});
$("#left2").click(function(){
$(".block2").css("margin-left","-=50px");
});
});
</script>

方法三


代码如下:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script language="javascript">
$(document).ready(function(){
$("#right3").click(function(){
$(".block3").animate({width:"+=50px"}, 222);
});
$("#left3").click(function(){
$(".block3").animate({width:"-=50px"}, 222);
});
});
</script>
