Changes to the AL-Rendering package allow for escape characters in tag
attributes. The changes in ALHtml5Tag>>writeOpenInto: to produce that
change (with the use of XTHtmlEntityWriteStream) but cause the
AjaxCounterExample to stop working. The double quotes, ", become "
and JavaScript becomes incomprehensible to the browser.
It looks like the following with ViewSource in a browser with the old
package, the new package, and a simple solution.
AjaxCounterExample>>renderScriptsOn: with older Render package:
new Counter("/76S.tbklwPZckEDg94Zqgn7tB.-"); counter.install("#count",
"#dec", "#inc");
AjaxCounterExample>>renderScriptsOn: with latest changer to Render package:
new
Counter("""""/76S.tbklwPZckEDg94Zqgn7tB.-""""");
counter.install("#count", "#dec", "#inc");
AjaxCounterExample>>renderScriptsOn: with single quotes.
new Counter('/76S.tbklwPZckEDg94Zqgn7tB.-'); counter.install('#count',
'#dec', '#inc');
The code in question is:
AjaxCounterExample>>renderScriptsOn:
[html text: 'var counter = new Counter("'.
html text: (html context registerResource: self resource) printString.
html text: '"); counter.install("#count", "#dec", "#inc");' ]
A simple solution could be to write JavaScript with pairs of single
quotes instead of double quotes. '' instead of ". Just a thought.
