一：JavaScript靜態(tài)頁(yè)面值傳遞之URL篇
能過(guò)URL進(jìn)行傳值.把要傳遞的信息接在URL上.Post.htm
復(fù)制代碼 代碼如下:
<input type="text" name="username"><input type="text" name="sex"><input type="button" value="Post"><script language="javascript" >function Post(){//單個(gè)值 Read.htm?username=baobao;//多全值 Read.htm?username=baobao&sex=male; url = "Read.htm?username="+escape(document.all.username.value);url += "&sex=" + escape(document.all.sex.value);location.href=url;}</script>
Read.htm
復(fù)制代碼 代碼如下:
<script language="javascript" >/--------------- Read.htm ----------------- Request[key] 功能:實(shí)現(xiàn)ASP的取得URL字符串,Request("AAA")* 參數(shù):key,字符串.* 實(shí)例:alert(Request["AAA"])--------------- Request.htm -----------------/var url=location.search;var Request = new Object();if(url.indexOf("?")!=-1){var str = url.substr(1) //去掉?號(hào) strs = str.split("&");for(var i=0;i<strs.length;i++){ Request[strs[i ].split("=")[0]]=unescape(strs[ i].split("=")[1]);}}alert(Request["username"])alert(Request["sex"])</script><script language="JavaScript"></script><script>String.prototype.getQuery = function(name){var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");var r = this.substr(this.indexOf("?")+1).match(reg);if (r!=null) return unescape(r[2]); return null;}var str ="www.jb51.net/index.htm?a=1&b=1&c=測(cè)試測(cè)試";alert(str.getQuery("a"));alert(str.getQuery("b"));alert(str.getQuery("c"));</script>
優(yōu)點(diǎn):取值方便.可以跨域.缺點(diǎn):值長(zhǎng)度有限制
二：JavaScript靜態(tài)頁(yè)面值傳遞之Cookie篇
Cookie是瀏覽器存儲(chǔ)少量命名數(shù)據(jù).它與某個(gè)特定的網(wǎng)頁(yè)或網(wǎng)站關(guān)聯(lián)在一起.Cookie用來(lái)給瀏覽器提供內(nèi)存,以便腳本和服務(wù)器程序可以在一個(gè)頁(yè)面中使用另一個(gè)頁(yè)面的輸入數(shù)據(jù).Post.htm
復(fù)制代碼 代碼如下:
<input type="text" name="txt1"><input type="button" value="Post"><script language="javascript" >function setCookie(name,value){/--------------- setCookie(name,value) ----------------- setCookie(name,value) 功能:設(shè)置得變量name的值* 參數(shù):name,字符串;value,字符串.* 實(shí)例:setCookie('username','baobao')--------------- setCookie(name,value) -----------------/var Days = 30; //此 cookie 將被保存 30 天 var exp = new Date();exp.setTime(exp.getTime() + Days2460601000);document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();location.href = "Read.htm"; //接收頁(yè)面.}</script>
Read.htm
復(fù)制代碼 代碼如下:
<script language="javascript" >function getCookie(name){/--------------- getCookie(name) ----------------- getCookie(name) 功能:取得變量name的值* 參數(shù):name,字符串.* 實(shí)例:alert(getCookie("baobao"));--------------- getCookie(name) -----------------/var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));if(arr !=null) return unescape(arr[2]); return null;}alert(getCookie("baobao"));</script>
優(yōu)點(diǎn):可以在同源內(nèi)的任意網(wǎng)頁(yè)內(nèi)訪問(wèn).生命期可以設(shè)置.缺點(diǎn):值長(zhǎng)度有限制.
**三：JavaScript靜態(tài)頁(yè)面值傳遞之Window.open篇
**這兩窗口之間存在著關(guān)系.父窗口parent.htm打開子窗口son.htm子窗口可以通過(guò)window.opener指向父窗口.這樣可以訪問(wèn)父窗口的對(duì)象.Post.htm
復(fù)制代碼 代碼如下:
<input type=text name=maintext><input type=button value="Open">Read.htm<script language="javascript" >//window.open打開的窗口.//利用opener指向父窗口.var parentText = window.opener.document.all.maintext.value;alert(parentText);</script>
優(yōu)點(diǎn):取值方便.只要window.opener指向父窗口,就可以訪問(wèn)所有對(duì)象.不僅可以訪問(wèn)值,還可以訪問(wèn)父窗口的方法.值長(zhǎng)度無(wú)限制.缺點(diǎn):兩窗口要存在著關(guān)系.就是利用window.open打開的窗口.不能跨域.
