> I use the functionnality of prependJavaScript to replace a composant with animation, but I have I a problem when I have two functions (on difference composants), one with normal syntax like this :
> {code:java}
> target.prependJavaScript("$('" + c.getMarkupId() + "').selectpicker('destroy')");
> {code}
> and I other one with special syntax for animation :
> {code:java}
> target.prependJavaScript(String.format("notify|var c=$('#%s.collapse');if(c.length){c.on('hidden.bs.collapse',function(){notify();});c.collapse('hide');}else{notify();}", c.getMarkupId()));
> {code}
> I get a error when wicket evaluate the javascript :
> {code:java}
> ERROR: Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript: SyntaxError: expected expression, got keyword 'var', text: (function(){$('#var1').selectpicker('destroy');})();(function(){notify|var c=$('#var2.collapse');if(c.length){c.on('hidden.bs.collapse',function(){notify();});c.collapse('hide');}else{notify();}})();
> {code}
> The problem is that the regexp "scriptWithIdentifierR" tests that the javascript is in form of *start with* "identifier|code" or my javascript don't start with "identifier|code" because is :
> {code:javascript}
> (function(){$('#var1').selectpicker('destroy');})();(function(){notify|var c=$('#var2.collapse');if(c.length){c.on('hidden.bs.collapse',function(){notify();});c.collapse('hide');}else{notify();}})();
> {code}
> There is 2 functions : the first is a normal function but the second is "identifier|code" function.
> If I change the var "scriptWithIdentifierR" (https://tinyurl.com/y8r24b5m) to :
> {code:Java}
> new RegExp("\\(function\\(\\)\\{([a-zA-Z_]\\w*)\\|((.|\\n)*)?\\}\\)\\(\\);$");
> {code}
> without the ^ of the first caractere that work nicely.
