I am trying to have 2 variable values passed in a url, which url will be redirected after. How can I insert them in a JavaScript string?
I have:
var a = document.getElementById("username_a").value;
var b = document.getElementById("username_b").value;
and want something like: var string_url = "http://www.example.com/?{a}blabla={b}" and then redirect somehow.
In PHP I would go with that code for example: <iframe src="http://www.example.com?query=<?php echo $the_variable;?>">
You can add strings in JavaScript, "a" + "b" == "ab" evaluates to true.
So what you want is probably var string_url = "http://www.example.com/?" + a + "&blabla=" + b;
But you should ever escape vars especially if they come from inputs, so try
a = encodeURIComponent(a);
b = encodeURIComponent(b);
And then
var string_url = "http://www.example.com/?" + a + "&blabla=" + b;
To redirect you can use window.location:
window.location = string_url;
use the ampersand to split vars
var string_url = "http://www.example.com/?" + "username_a=" + a + "&username_b=" + `b
Could be made more sopisticated, but that in essence is what you need
JavaScript doesn't do string interpolation. You have to concatenate the values.
var uri = "http://example.com/?" + encodeUriComponent(name_of_first_variable) + "=" + encodeUriComponent(value_of_first_variable) + '&' + encodeUriComponent(name_of_second_variable) + "=" + encodeUriComponent(value_of_second_variable);
location.href = uri;
