How to get text with preg_match and Regex in Javascript ? | |||||||||||
| I need to extract text value like I usually do with preg_match() in PHP. But now I need to do it in Javascript. Can you please give me advice and example how to make it work ? | |||||||||||

| Hi, The similar function to preg_match() in Javascript is exec(). It can be used to find a match or extract the specific text from string, according to regex pattern condition. In this example, the function will extract the text between <ABC></ABC> tags: var string = '<\ABC>The content<\/\ABC>'; var pattern = /<\ABC>(.*)<\/\ABC>/; var text = pattern.exec(string)[1]; | |||||||||||

| Thank you. Can I also use regex modifiers in Javascript ? For example to perform case-insensitive or multiline search etc. | |||||||||||

| Yes, the modifiers can be used, when needed. For example you can use: g - to find all matches, rather than stopping after the first match m - to multiline matching i - to case insensitive matching The code with regex modifiers will look like: var string = '<\ABC>The content<\/\ABC>'; var pattern = /<\ABC>(.*)<\/\ABC>/im; var text = pattern.exec(string)[1]; | |||||||||||
