replace "&" by its URL symbol "%26"

[vigi98]

Hello all,

Can someone confirme that this:
var strURLpiece = "UK & Ireland";
strURLpiece.replace("&", "%26");
replaces all occurrence of the character & by %26 in strURLpiece, ie
that strURLpiece becomes "UK %26 Ireland" ?

Thanks a lot.

If anyone does then don't trust them because it won't.

Thanks for this very helpfull solution. Nevertheless, what is the
solution ? I also tried this:
strURLpiece.replace(/&/,"%26");
but it does not work better.

Thanks for this very helpfull solution. Nevertheless, what is the
solution ? I also tried this:
strURLpiece.replace(/&/,"%26");
but it does not work better.

This worked in ie 6.0 and mozilla 1.6:

alert("UK & Ireland".replace(/[&]/g,"%26"));

RegExp is for me so tricky to use that I made a small testbed to have
exercises in using it:

function evaluoi(r,s){
var re=new RegExp(r);
var myArray=new Array();
if (re){
myArray=re.exec(s);
if (myArray){alert(myArray.length+'\n'+myArray+'\n'+re.source);}
return re.test(s) ;
}
return false;
}




<form name="fname" action="#" method="get">
RegExp=
<input name="r" type="text" value="(\d{5})([a-z]*)(\s)+(\*$)"><br>
string=
<input name="s" type="text" value="12345abc *"><br>
RegExp.test(string)=
<input name="a" type="text" value="?"><br>
<input type="button" value="evaluoi"
onclick="document.forms['fname'].a.value=evaluoi(document.forms['fname'].r.value,document.forms['fname'].s.value);">
</form>

You can ignore the initial example values in the form fields.

Note that typing expressions to a form is different from using the
expressions in the progrmam code.

alert("UK & Ireland".replace(/[&]/g,"%26"));

Without the [] works as well:

alert("UK & Ireland &cetera".replace(/&/g,"%26"));

It appears to replace all ampersands in "UK & Ireland".
It only replaces the first ampersand in "&&" & " & & "

You wanted the value of strURLpiece to change. For that you need an
assignment. The replace method does not change the string. So, at least;

strURLpiece = strURLpiece.replace(/&/,"%26");

The next problem is the "&". If the script is embedded in HTML, the
ampersand has a special meaning, and should be (HTML-)escaped:

strURLpiece = strURLpiece.replace(/&amp;/,"%26");

If the script is not embedded in Javascript, then you should not escape
the ampersand. If you want to avoid thinking about it, you can use a
Javascript escape:

strURLpiece = strURLpiece.replace(/\x26/,"%26");

Good luck.
