I am learning the Prototype library in-depth and my question is about the inner logic of the Template.evaluate method. Everything is clear as long as the original match provided by the gsub function from the stored template is further processed.
a.) what kind of scenario is the inner regular expresion used to handle? b.) what is going on in the while loop /* cut */ var pattern = /^([^.[]+|\[((?:.*?[^\\])?)\])(\.|\[|$)/; match = pattern.exec(expr); if (match == null) return before; while (match != null) { var comp = match[1].startsWith('[') ? match[2].replace(/\\\\]/ g, ']') : match[1]; ctx = ctx[comp]; if (null == ctx || '' == match[3]) break; expr = expr.substring('[' == match[3] ? match[1].length : match[0].length); match = pattern.exec(expr); } /* cut */ -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
