<script type="text/javascript">
一、获取url所有参数值
function US() {
var name, value
var str = location.href
var num = str.indexOf("?")
str = str.substr(num + 1)
var arr = str.split("&")
for (var i = 0 i < arr.length i++) {
num = arr[i].indexOf("=")
if (num > 0) {
name = arr[i].substring(0, num)
value = arr[i].substr(num + 1)
this[name] = value
}
}
}
二、使用JS 发送JSON格式的POST请求
var us = new US()
var xhr = new XMLHttpRequest()
xhr.open("POST", "/searchguard/api/v1/auth/login", true)
xhr.setRequestHeader("Content-type", "application/json")
xhr.setRequestHeader("kbn-version", "5.3.0")
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
window.location.href = us.nextUrl
}
}
}
xhr.send(JSON.stringify({
"username" : us.u,
"password" : us.p
}))
</script>
其实你完全可以采用jquery的ajax方式来读取.var result = false
var thenow = new Date()
$.ajax({
type:"POST",
url:"此处为相对路径的php文件?Time="+thenow.getMilliseconds()+"M"+thenow.getSeconds()+"",
data:{id:id},
success:function(data){
}
})
如果你不用jquery
var xmlHttps = new Array(10)
var e
var EndHtml=false
//创建XMLHTTP对象
function getXMLHTTPObj()
{
var C = null
try
{
C = new ActiveXObject("Microsoft.XMLHTTP")
}
catch(e)
{
try
{
C = new ActiveXObject("Msxml2.XMLHTTP")
}
catch(sc)
{
C = null
}
}
if( !C && typeof XMLHttpRequest != "undefined" )
{
C = new XMLHttpRequest()
}
return C
}
function GetDetail(userid,id)
{
document.getElementById(id).innerHTML = ""
try
{
xmlHttps[id]=false
xmlHttps[id]= getXMLHTTPObj()
if( xmlHttps[id] )
{
var realUrl = "/Ajax.aspx?action="+id+"&userid=" + escape(userid)+"&date="+new Date().getTime()
xmlHttps[id].open("get", realUrl, true)
//设置回调函数
xmlHttps[id].onreadystatechange = function(){updatePage(id,xmlHttps[id])}
//发送请求
xmlHttps[id].send(null)
// xmlHttps.abort()
}
else
{
document.getElementById(id).innerHTML = "<font color=#ff0000>×</font>您的浏览器不支持"
}
}
catch (e)
{
document.getElementById(id).innerHTML = "<font color=#ff0000>×</font> 发生异常"
}
}
第一种提交post的方式是传统方式，判断浏览器进行post请求。<SCRIPT stype=text/javascript>
var xmlobj//定义XMLHttpRequest对象
function CreateXMLHttpRequest()
{
if(window.ActiveXObject)
//如果当前浏览器支持Active Xobject，则创建ActiveXObject对象
{
//xmlobj = new ActiveXObject("Microsoft.XMLHTTP")
try {
xmlobj = new ActiveXObject("Msxml2.XMLHTTP")
} catch (e) {
try {
xmlobj = new ActiveXObject("Microsoft.XMLHTTP")
} catch (E) {
xmlobj = false
}
}
}
else if(window.XMLHttpRequest)
//如果当前浏览器支持XMLHttp Request，则创建XMLHttpRequest对象
{
xmlobj = new XMLHttpRequest()
}
}
function SubmitArticle(act,cityname,antique) //主程序函数
{
CreateXMLHttpRequest()//创建对象
//var parm = "act=firstweather" //构造URL参数
//antique = escape(antique)
var parm = "act=" + act + "&cityname=" + cityname + "&antique=" + antique//构造URL参数
//xmlobj.open("POST", "{dede:global.cfg_templeturl/}/../include/weather.php", true)//调用weather.php
xmlobj.open("POST", "/weather/include/weather.php", true)//调用weather.php
xmlobj.setRequestHeader("cache-control","no-cache")
xmlobj.setRequestHeader("contentType","text/htmlcharset=uft-8") //指定发送的编码
xmlobj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded") //设置请求头信息
xmlobj.onreadystatechange = StatHandler //判断URL调用的状态值并处理
xmlobj.send(parm)//设置为发送给服务器数据
}
第二种方式则是虚拟表单的形式提交post请求
function post(URL, PARAMS) {
var temp = document.createElement("form")
temp.action = URL
temp.method = "post"
temp.style.display = "none"
for (var x in PARAMS) {
var opt = document.createElement("textarea")
opt.name = x
opt.value = PARAMS[x]
// alert(opt.name)
temp.appendChild(opt)
}
document.body.appendChild(temp)
temp.submit()
return temp
}
调用方法 如：
复制代码 代码如下:
post('pages/statisticsJsp/excel.action', {html :prnhtml,cm1:'sdsddsd',cm2:'haha'})
