{Get the data closest to the first comma, i.e. Substring_index (Substring_index (a.msize, ', ', b.id), ', ',-1)i = i +1}id = ID +1}Summarize:The disadvantage of this approach is that we need a separate table with sequential numbers (here is incre_table). and the maximum value of a continuous series must be greater than the number of values that match the split.For example, if a row of msize has 100 comma-separated values, then our incre_table needs to have at least 100 contiguous rows.Of course

A field in the database is spliced with commas (,). Each field is the primary key of another table. You need to query the child element or delete the element for the field spliced with commas, there will be more complex string parsing. Therefore, the split method provided by string is tested first. As you can see, all the commas before the element are considered as delimiters and are split into a string a

call exec to iterate through all the matches, equivalent to match with the G flag. Of course, if the regular expression forgets to use G, and then uses the loop (for example: while, for, etc.), Exec loops the first one each time, causing a dead loop. EXEC's output will contain child matches. Example 3: Copy Code code as follows: function Execdemo () { var r, re; Declare a variable. var s = "The rain in Spain falls mainly in the plain"; Re =/[\w]* (AI) n/ig; R = re.exec (

Test: tests Whether a string contains a matching result, contains a return of true, and does not contain a return of false. match: Regular match based on pattern, if matched to, returns match result, such as no match to return null Search : a regular match based on pattern, and returns the number of indexes if it matches a result; 1 Split: Regular segmentation According to pattern, returns a segmented ar

Exec: Regular Expression is performed on the string, and the matching result is returned. array [0] is the original string, and array [I] is the position that matches the entire string to be searched. Test: test whether a string contains a matching result. If the string contains a matching result, true is returned. If the string does not contain a matching result, false is returned. Match (pattern): regular

ReplaceText can also be a function return value that returns a string: Returns the replacement string Example 1:varstr ="AAABBBCCCAAABBBCCC"; varReg =/aaa/; varres = str.replace (Reg, ' 111); Console.log (res);//return 111BBBCCCAAABBBCCC, replace only the first match, if you need to replace all you need to use the G option5.
