preface
This article has participated in the “Digitalstar Project” and won a creative gift package to challenge the creative incentive money.
Regular expression for the front end is very familiar, especially form verification, I do activity development, experienced all kinds of information filling, specially collated and collected a number of commonly used and not commonly used regulars.
I’ve documented them so you can look them up. The document has re, but not only re, there are many common JS methods waiting for you to discover, hope friends more support ~
👉👉 Online documentation
👉👉 source code address
Feel helpful to your partner to help click a star, or often come to the document to see, update more JS skills irregularly. Online documents have access to Baidu statistics, small partners can increase access, welcome everyone to let my data change better look some ~.
If you find errors, please correct them in the comment area, or you can add other common re in the comment area, and you can also raise new requirements ~
