help with quotes, please...

[Aaron Fude]

I have this

<img src="a.jpg" onClick=this.src="b.jpg\"">

and it works. But I like obeying rules so I change it to

<img src="a.jpg" onClick="this.src=\"b.jpg\"">

and it no longer works.

Please note that I really cannot do the alternating
single-quote-double-quote thing is the onClick action is set programatically
and it is hard to detect exactly what's inside.

Thanks!

<img src="a.jpg" onClick="this.src=b.jpg;">

as long as you do not use spaces in the second jpg name

======== or =======

<script>
function myB(x){ x.src="b with spaces.jpg"};
</script>

<img src="a.jpg" onClick="myB(this);">

That does not seem a valid statement, if you can enter \" you can enter
an apostrophe/single quote programmatically too.

It wouldn't. HTML doesn't respect backslash as an escape character. It
literally sees \" and interprets it as the end of the attribute. Either
you use single quotes, or the &quot; entity reference.

<img src="a.jpg" onClick="this.src=b.jpg;">

But that wouldn't work, would it. It would be interpreted as: "assign the
value of property jpg of object b, to property src of the current object
(represented by this)". You would have to quote the string.

I agree.

Replace ".invalid" with ".uk" to reply by e-mail.
