Question

Ok, I m new to Java, 在此需要一些帮助。在一页前线/后向纽州开展工作。基本上,该章看上去的是<编码>http://webaddress.com/details?id=27。

因此,我的两个职能是提取ur,然后向同一页推缩或加固细节,必要时,当一个 but子被点击时。例如,有人在下顿点击id=28;如果先前点击,id=26。

我认为,它有点可笑,我已经看到,它以前做了一些工作,但并不肯定做了些什么。

I need idea on how to approach it. Any help will be appreciated.

<>Update: 我使用了下文的@gion_13条代码,但像Im错sin那样。似乎没有工作。任何其他帮助都将受到赞赏。

Answer 1

function parseUrl(){
    if(location.href.indexOf( ? ) == -1)
        return null;
    var aux = location.href.split( ? );
     var result = {
         href  : aux[0],
         params  : {}
    };
    var p = aux[1].split( & );
    for(var i=0,l=p.length;i++)
        {
             var kv = p[i].split( = );
             params[kv[0]] = kv[1];
        }        
    return result;
}

function reconstructUrl(obj){
    if(!obj)
        return location;
    var url = obj.href +  ? ;
    for(var i in obj.params)
        url += i +  =  + obj.params[i] +  & ;
    return encodeURI(url);
}

function getNextUrl(){
    var urlObj = parseUrl();
    urlObj.id++;
    return reconstructUrl(urlObj);
}

function getPrevUrl(){
    var urlObj = parseUrl();
    urlObj.id--;
    return reconstructUrl(urlObj);
}

Answer 2

您可使用<代码>所在地。

http://developer.mozilla.org/en/window.location

利用<代码>exec提取识别符号。

extracted_id = /id=([0-9]+)$/.exec(location.href)[1]

http://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/RegExp/exec

Answer 3

Read the url as var url = document.location.href
Use regEx or indexOf "=" or document.location.search to find current page no
Parse as int and +/- page number
rebuild the the url
document.location.replace(newurl)

Answer 4

<代码>window. place Object has the URL info You need. 你们可以使用一种reg。这里有些提及:

Answer 5

查阅网页电子版,使用文件。例如:

document.write(document.URL);

You can then modify the URL and open the new URL.

For lots of hints and tips, See JavaScript HTML DOM Examples.

Answer 6

You can do that without Javascript if you want. I think it s more efficient with PHP, because it will work even if some user has Javascript disabled.

You can try get the id like this:

<?php $my_id = $_GET[ id ]; ?>
