js每个地区获取的时间戳是一样的吗,第1张

不一样。

不同的设备，本地的系统时间是不一样的，假如你电脑设定的时间是9：00那么js获取的就是9：00但是如果此时别人的电脑时间是10：00在别人的电脑上js获取的时间就是10：00。

s是客服端脚本，是不能直接获取服务器端的时间的，除非你用asp，或者jsp，php，等写一个动态的js脚本。

1.

首先写一个js文件，areaLocation.js:

var

provinceArray=

new

Array()

provinceArray=[

{"pname":"江苏",

"country":[

{

"cname":"南京市",

"town":["玄武区","白下区","秦淮区","建邺区","雨花台","江宁区",

"六合区","溧水县","高淳县"]},

{

"cname":"南通市",

"town":["崇川区","港闸区","启东市","如皋市","通州市","海门市","海安县","如东县"]

},

{

"cname":"苏州市",

"town":["金阊区","沧浪区","平江区","虎丘区","吴中区","张家港","昆山市","吴江市","太仓市"]

}

]

},

{"pname":"上海",

"country":[

{

"cname":"上海市",

"town":["徐汇区","普陀区","杨浦区","虹口区","卢湾区","浦东区","黄浦区","长宁区","闸北区","静安区","闵行区","松江区"]

}

]

}

]

function

areaInitialize(){

province.length=1

for(var

i

=

0i<provinceArray.lengthi++){

var

pro

=

provinceArray[i].pname

province.options[province.length]

=

new

Option(pro,pro)

}

}

function

changeCLocation(id,city){

//alert(id)

city.length

=

0

if(id>0){

var

j=id-1

var

i

var

countrys

=

new

Array()

countrys

=

provinceArray[j].country

city.options[0]

=

new

Option('不限','')

for

(i=0i

<

countrys.length

i++){

var

cname

=

countrys[i].cname

city.options[city.length]

=

new

Option(cname,

cname)

}

changeTLocation(id,1,town)

}else

if(id==0){

city.length

=

0

town.length

=

0

city.options[city.length]

=

new

Option('不限','')

town.options[town.length]

=

new

Option('不限','')

}

}

function

changeTLocation(pid,cid,town){

//alert(cid)

var

countrys

=

new

Array()

var

towns

=

new

Array()

town.length

=

0

var

i

countrys

=

provinceArray[pid-1].country

areaId

=

countrys[cid-1].areaId

towns

=

countrys[cid-1].town

city.options[0]

=

new

Option('不限','')

town.options[0]

=

new

Option('不限','')

for

(i=0i

<

towns.length

i++){

var

tname

=

towns[i]

town.options[town.length]

=

new

Option(tname,tname)

}

town.options[0]

=

new

Option('不限','')

}

2.

再写一个html页面：

<!DOCTYPE

HTML

PUBLIC

"-//W3C//DTD

<html>

<head>

<script

type="text/javascript"

></script>

<script

type="text/javascript">

window.onload=areaInitialize()

</script>

</head>

<body>

<select

size="1">

<option

value=0

selected>--请选择--</option>

</select>

<select

size="1"

>

<option

value=0

selected>--请选择--</option>

</select>

<select

size=1>

<option

value=0

selected>--请选择--</option>

</select>

</body>

</html>
