in javascript on button click redirect to current url + text from js function -

i redirect current "url" + "text" returned function1 when button clicked, in javascript:

function function1() {     return window.location.href + "/search"; } <button id="mybutton" onclick=function1()> </button> 

what solution achieve this?

my attempt doesn't work. in advance.

try out. need replace/change current href

function function1() {                  window.location.href = window.location.href + "/search";  }

<button id="mybutton" onclick=function1()> </button>

as added note can use window.location.replace(window.location.href + "/search"); replace current page , not keep in history. i.e. user cannot go previous page redirected page.
