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。

<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

复制代码代码如下:

<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

复制代码代码如下:

<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>
