Javascript replace?

Question

<script>
var text = "a's ..a's ...\"... ";
text = convert(text);
function convert( text )
{
 var n = text.replace(/\'/g, "&#039;");
 n = text.replace(/\"/g,"&quot;");
 return n;
}
console.log(text);
document.write(text);
</script>

The problem is that when it replace the second time it take doesnt "remember" what it replaced the first time, so only the last replace is returned.

Answer 1

That's because you are replacing the original text string in the second replace, instead of n, which is the value of the replaced text:

function convert( text )
{
 var n = text.replace(/\'/g, "'");
 n = n.replace(/\"/g,""");
 return n;
}

replace does not modify your original string. Instead, it returns a new modified string . You can also do both replaces in a single statement:

return text.replace(/\'/g, "'").replace(/\"/g,""");

Answer 2

function convert( text )
{
 var n = text.replace(/\'/g, "'");
 // Wrong: n = text.replace(/\"/g,""");
 // This modifies the previously edited variable.
 n = n.replace(/\"/g,""");
 return n;
}
