Append parameter in url without reloading page

Question

I am using following code to append param to url. This is working fine but when parameter is appended in url, page is getting reloaded. I want to use this functionality without reloading the page .

function insertParam(key, value)
{
 key = escape(key); value = escape(value);
 var kvp = document.location.search.substr(1).split('&');
 var i=kvp.length; var x; while(i--) 
 {
 x = kvp[i].split('=');
 if (x[0]==key)
 {
 x[1] = value;
 kvp[i] = x.join('=');
 alert('sdfadsf');
 break;
 }
 }
 if(i<0) {kvp[kvp.length] = [key,value].join('=');}
 //this will reload the page, it's likely better to store this until finished
 document.location.search = kvp.join('&'); 
 //alert(document.location.href);

}

I want to add multiple params to url without reloading the page like:

• txt1
• txt2
• txt3

• link1
• link2
• link3

i want url : "..../search.php"

after click on txt2 i want url : "..../search.php#t_2"

after click on link2 i want url : "..../search.php#t_1&l_2"

Answer 1

You can only do this using history.pushState(state, title, url) which is an HTML5 feature.

• Nadh: I think the OP only wants to append fragments to the url, for example document.location.href += '#txt'
• Alnitak: @NADH he never said that - the code (and the original question) talked about query parameters, not anchor fragments.

Answer 2

There is a new feature that aims to replace the use of location.hash with a better solution: pushState.

 window.history.pushState(data, "Title", "/new-url");
