onChange(..) what's wrong?

[Omar]

Hi,

In the next sentence, what's wrong?

<select name='id' onChange="window.location='dePaso.jsp?vuelta=a&nombre=id&anterior=ejecutivo
= 'Daniel Perez'&valor='+this.options[this.selectedIndex].value">

IE complains about missing ";"

TIA

Try:

<select name='id' onChange="
window.location=encodeURI(
'dePaso.jsp?vuelta=a&nombre=id&' +
'anterior=ejecutivo=' +
'Daniel Perez' +
'&valor=' +
this.options[this.selectedIndex].value);
">

In the next sentence, what's wrong?

<select name='id'

onChange="window.location='dePaso.jsp?vuelta=a&nombre=id&anterior=ejecutivo
^-- Here the JS string starts ...

= 'Daniel Perez'&valor='+this.options[this.selectedIndex].value">

^----.
.... and here it ends. Since `Daniel' is not a valid reference,
the script engine yields a runtime (syntax) error:

IE complains about missing ";"

If you use ' as string delimiter, escape 's within it with \'
Note that you cannot escape attribute value delimiters within
attribute values this way which imposes a limitation upon the
nesting level of string literals.

the script engine yields a runtime (syntax) error:

Syntax errors (as this is) are generated when the script source code is
interpreted, before it is executed (and source with syntax errors
doesn't get executed), and so they are not runtime errors.

If you use ' as string delimiter, escape 's within it with \'
Note that you cannot escape attribute value delimiters within
attribute values this way which imposes a limitation upon the
nesting level of string literals.

Hex and Unicode escape sequences may be used within ECMAScript string
literals, so the delimiters used for attribute values do not need to be
an issue.
