Question

Hi I have a problem here. I am trying to replace all instances of + character in a string using javascript. What happens is that only the first instance is being changed.

Here is my code:

var keyword = "Hello+Word%+";
keyword = keyword.replace("+", encodeURIComponent("+"));
alert(keyword);

The output is Hello%2BWord%+ when it should be Hello%2BWord%%2B because there are 2 instances of +.

Please help. Thanks in advance.

You need the global flag.

var keyword = "Hello+Word%+";
keyword = keyword.replace(/\+/g, encodeURIComponent("+"));
alert(keyword);​
