Encode URL in JavaScript? -

how safely encode url using javascript such can put string?

var myurl = "http://example.com/index.html?param=1&anotherparam=2"; var myotherurl = "http://example.com/index.html?url=" + myurl; 

i assume need encode myurl variable on second line?

check out built-in function encodeuricomponent(str) , encodeuri(str).
in case, should work:

var myotherurl =         "http://example.com/index.html?url=" + encodeuricomponent(myurl);
