This article mainly introduces why eval in JS needs to enclose JSON data. For more information, see the rise of Ajax, the lightweight JSON data format gradually becomes popular as the transmission format between the client and the server. The problem that arises is how to convert the JSON Data Built on the server to available JavaScript objects. Using eval functions is undoubtedly a simple and direct method. During conversion, enclose the JSON string with parentheses: The Code is as follow

Title Description:Define the valid parentheses sequence as follows:1 empty sequence is a valid sequence2 If S is a valid sequence, then (s) and [s] are also valid sequences3 If A and B are valid sequences, then AB is also a valid sequenceFor example: The following are the valid parentheses sequence(), [], (()), ([]), ()[], ()[()]The following are all illegal parenthesis sequences.(, [, ), ) (, ([)], ([(]Given a sequence consisting of ' (', ') ', ' [', ' and '] ', find the shortest legal sequence

DescriptionThis was yet another problem dealing with regular bracket sequences.We should remind you a bracket sequence are called regular, if by inserting«+»and«1»into It we can get a C Orrect mathematical expression. For example, Sequences«(()) ()»,«()»and«(() (())»are Regular, while«) (»,«(()»and«(())) (»a Re not. You are given a string of«(»and«)»characters. You were to find it longest substring that was a regular bracket sequence. You is to find the number of such substrings as well.I

)")))))' I need to pass the regular, matching the innermost parentheses in the string and their contents (not matching the parentheses in the quotation marks), i.e.: str1 => (status_id = "C" OR level_id = "D")str2 => (level_id = "D" AND subject_id = "(Cat)") So what is this hyper-complex regular supposed to write? If the regular implementation is not, then how to achieve JS? Add, for str1 , I found such a regular can satisfy the match: \([^()]+\) But for str2, there is still no way to look forwa

This article describes how to intercept parentheses in Python regular expressions, and involves Python regular expression matching techniques, for more information about how to use Python regular expressions to intercept parentheses, see the following example. We will share this with you for your reference.
