1、$("#demo").attr("style","display:none;");//隐藏div
$("#demo").attr("style","display:block;");//显示div
2、$("#demo").css("display","none");//隐藏div
$("#demo").css("display","block");//显示div
3、$("#demo").hide();//隐藏div
$("#demo").show();//显示div
4、$("#demo").toggle(//动态显示和隐藏
function () {
$(this).attr("style","display:none;");//隐藏div
},
function () { $(this).attr("style","display:block;");//显示div
}
);
<div id="demo"></div>
注：
$("#demo").show()表示display:block,
$("#demo").hide()表示display:none;
1和2中的display:none可以换成visibility:hidden，display:block可以换成visibility:visible.两者的区别是前者隐藏后不占空间，而后者隐藏后会占空间
例：
-
<script type="text/javascript"> -
function showDiv1(){ -
//$("#test1").attr("style","display:block"); -
//$("#test1").show(); -
$("#test1").css("display","block"); -
} -
function showDiv2(){ -
//$("#test2").attr("style","visibility:visible"); -
$("#test2").css("visibility","visible"); -
} -
function hiddenDiv1(){ -
$("#test1").hide(); -
} -
function hiddenDiv2(){ -
$("#test2").attr("style","visibility:hidden"); -
} -
</script> -
</head> -
<body> -
<div id="test1" style="display:none">aaaaaa</div> <%--隐藏的div--%> -
<div id="test2" style="visibility: hidden">bbbbb</div> <%--隐藏的div--%> -
<button onclick="showDiv1()">显示1</button> -
<button onclick="showDiv2()">显示2</button> -
<button onclick="hiddenDiv1()">隐藏1</button> -
<button onclick="hiddenDiv2()">隐藏2</button> -
</body>
