Add query string to url using anchor link

Question

UPDATE

Sorry my qusetion was unclear i have updated my question

I want to add a query string in the end of url using anchor

For example if i have url

www.mysite.com/home

And have anchors on this page

 <a href='?page=1'>1</a>
 <a href = '?page=2'>2</a>
      .
      .
 <a href = '?page =x'>x</a>

When i click on these anchor link it directs me to Url

www.mysite.com/home?page=x

That what i want , I just want to add query string page in the end of the url,

But in the case of

www.mysite.com/home?category=sports

Or

www.mysite.com/home?category=music

Then if i click on the same anchor link

It redirects me to

www.mysite.com/home?page=x

But i want it to direct me to

www.mysite.com/home?category=sports&page=x

And now if i again on any of those link like

<a href='?page=1'>1</a>

Then i want it to direct me to

www.mysite.com/home?category=sports&page=1

is their any simple solution to do this , Or i have to use any complex javascript code.

Answer 1

It is simple.

var url ="www.mysite.com/home?page=1"; 
var result = url + (url.indexOf('?')== -1 ?  "?page=1" : "&page=1")

Answer 2

我不建议使用它，但我认为这是唯一的解决方案：

<a href="Javascript: if (window.location.href.indexOf('page=')==-1) { window.location=(window.location.href+ (window.location.href.toString().indexOf('?')>-1 ? '&page=1': '?page=1'))}">click here</a>

Answer 3

window.location.replace(url);

url - is the string you want to open

Answer 4

You have to add all params to the link, like this:

<a href='?category=sports&page=1'>1</a>
<a href='?category=sports&page=2'>2</a>
.
.
.
<a href='?category=sports&page=x'>x</a>
