<script type="text/javascript">
    alert('clientWidth:'+document.getElementById("s").clientWidth);
    alert('clientHeight:'+document.getElementById("s").clientHeight);
    alert('offsetWidth:'+document.getElementById("s").offsetWidth);
    alert('offsetHeight:'+document.getElementById("s").offsetHeight);
    alert('scrollWidth:'+document.getElementById("s").scrollWidth);

    alert('screen.width:'+window.screen.width);
    alert('screen.availHeight:'+window.screen.availHeight);
    alert('screen.availWidth:'+window.screen.availWidth);

//innerWidth不包括border和margin
$("div").innerWidth(function(index,innerWidth){
    return Math.max(innerWidth,150);//设置内宽度为不小于150
})
$("#a").innerWidth(20);//设置内宽度为20

$(document).ready(function(){
    $("p:eq(0)").css("background-color","#dddddd");//选择器
})

$("img").attr("width");//获取属性
$("img").attr("width","180");//设置属性值
$("img").attr({width:"50",height:"80"});
$(this).find("input[type=radio]").attr("checked",true);

// join() 方法用于把数组中的所有元素放入一个字符串。
var arr = new Array(3)
arr[0] = "George"
arr[1] = "John"
arr[2] = "Thomas"
document.write(arr.join())
