"&"

[diamondnular]

Hi all,

I am trying to write a php code which outputs javascript code like this:

var a="b&c"

but finally, the output source code is

var a="b&c"

My question is: Is there a javascript function read a string containing "&" as "&" like function htmlspecialchars_decode in php?

Thanks,

KC.

Its not a built in function, but here is one.

See String Methods >> entityify()

Ok.

Just add this at the top of your script and call it with

var a = "b & c".deentityify()

String.prototype.deentityify = function () 
  {
    return this.replace(/&amp;/g,"&").replace(/&lt;/g,"<").replace(/&gt;/g,">");

}

Hi Bob90,

Thanks. But I think replacing method does not work here, as every "&" will be translated to "&" in html source code:

var a = "b & c".deentityify()

String.prototype.deentityify = function () 
  {
    return this.replace(/&amp;/g,"&").replace(/&lt;/g,"<").replace(/&gt;/g,">");
  }

becomes:

var a = "b & c".deentityify()

String.prototype.deentityify = function () 
  {
    return this.replace(/&amp;amp;/g,"&amp;").replace(/&amp;lt;/g,"<").replace(/&amp;gt;/g,">");
  }

Am I right?

Check out my second post. Made my own.

OK i see now. Well that has to be PHP then as I can't think of any code.

Unless you use unescape() and instead of & you use %26?

But probably not useful.

Hi Bob90,

Noop, it really helps. This is what I finally came up with:

var a = 'b' + unescape('%26') + 'c';

There is no "&" in the code and the code works just fine. Thanks a lot.
