http://localhost/zyntegra_commoditylifev2/admin/category/viewcategory/sid/10

, if it's (3) 1 there no need of reload.

plz me solve problem.

thanks in advance

try like,

var tagsurl='http://localhost/zyntegra_commoditylifev2/admin/sitetag/viewtags/sid/'; var caturl='http://localhost/zyntegra_commoditylifev2/admin/category/viewcategory/sid/'; $(function(){     $('#your-select-id').on('change',function(){        href=window.location.href;        if(href.indexof('viewtags') !== -1){            window.location.href=tagsurl+this.value;//append value of select element        } else if(href.indexof('viewcategory') !== -1){            window.location.href=caturl+this.value;//append value of select element        }     }); }); 

above code may complete task.

updated, sid try like,

// use location.href in url current url var url='http://localhost/zyntegra_commoditylifev2/admin/sitetag/viewtags/sid/110'; alert(url.split('sid/')[1]);//110  

updating @salini answer like,

function reloadpage() {                  var sid = $( '#site_selectedsiteid' ).val( );     var currenturl = window.location.pathname;     var n=currenturl.indexof("/sid");// use '/sid' in indexof remove else part     if(n!=-1) {         var newurl = currenturl.substring(0,n);          window.location.href = newurl + '/sid/' + sid;     } }
