I picked a post titled common JavaScript functions from the Internet two days ago, which contains verification functions that are commonly used on the client, however, all the functions in it use the string Decomposition Method for judgment,ArticleAfter submission, many friends suggested that many functions can be replaced by regular expressions. I will change these functions to regular expressions for verification tonight. Please give me some advice if they are good or not. // Use this e

This article describes how to use JavaScript to determine the length, number, Email, phone number, and other commonly used judgment functions. This article provides the implementation code directly.

Javascript Form Verification Regular Expressions Use a regular expression to determine whether it is a 0-9 Arabic number CopyCode The Code is as follows: function regisdigit (fdata) { VaR Reg = new Regexp ("^ [0-9] $ "); Return (Reg. Test (fdata )); } Use this expression to obtain the string length.Copy codeThe Code is as follows: function regdatalength (fdata)

* Data [TID]. Y +Data [TID]. z * data [TID]. Z;} It is not coalesced reading because the vec3d size is 12 bytes instead of 4 bytes, 8 bytes, or 16 bytes. To solve this problem, use the _ align (n) _ Directive, for example: Struct _ align _ (16) vec3d {float x, y, z ;}; This causes compiler to add an empty 4 bytes behind vec3d to complete 16 bytes. Another method is to convert the data structure into three consecutive arrays, for example: _ Global _ void func (float * X, float * y, float
