BOM浏览器模式和window对象学习
</title>
<!--
BOM浏览器模式(Browser Object Mode)这是一种理想的模式，如果每个浏览器开发商都按照这种方式来开发，
就会提高开发效率，使互联网朝着健康的方向发展。
具体的实现是window对象
1.框体方法
：alert();警告，无返回值
confirm();确认，有返回值，确定返回true，取消返回false
prompt();提示，有返回值，确定返回当前输入的值，取消返回null
2.定时执行和间隔执行
：
setTimeOut(code expresion,time)，指定时间后开辟线程执行指定的函数，返回线程id
setInterval(code expresion,time),指定时间后开辟线程执行指定的函数，返回id
ClearInterval(id),关闭指定的interval开启的线程
ClearTimeOut(id),关闭指定的Timeout开启的线程
3.子页面
open()使用此方法可以打开当前页面的子页面，使用以下属性可以设置子页面窗口的大小和其他属性
//height width top left
//toolbar=yes; menubar=yes;scrollbars=no;resizable=no;location=no;status=no;
close(),在open()打开的子页面中调用此方法
重要属性
opener
,使用opener可以调用父页面的函数 window.opener.函数名();
-->
<script type="text/javascript">
//window方法举例
//1.警告框
function testAlert(){
window.alert("我是警告框");
}
//2.确认框
function testConfirm(){
var flag=window.confirm("你要卸载我吗？");
window.alert(flag);
}
//3.提示框
function testPrompt(){
var str=window.prompt("请输入昵称：","例如：李白");
window.alert(str);
}
/*--------------------------------------------------------------------------*/
//定时执行
var tid;
function testSetTimeOut(){
tid=window.setTimeout(function(){
alert("定时执行");
},3000);
}
//间隔执行
var id;
function testInterval(){
id=window.setInterval(function(){
alert("间隔执行");
},2000);
}
//关闭间隔执行
function testClearInterval(){
window.clearInterval(id);
}
//关闭定时执行
function testClearTimeOut(){
window.clearTimeout(tid);
}
/*----------------------------------------------------------------------------------------*/
function testOpen1(){
window.open("http://www.baidu.com");//使用open打开网络资源
}
function testOpen2(){
window.open("sun.html");//使用open打开本地资源
}
//属性
function testOpener(){
alert("我是Opener");
}
</script>

<body>
<input type="button" id="" value="测试windowAlert" onclick="testAlert();"/>
