Mailbox Verification

1, using function functions to achieve

Note: You need to add a property to the tag in code <input>: onblur= "Loginemailblur (this.value)"

function Loginemailblur (stremail) {            var loginemail = $.trim ($ ("input[name= ' email ']"). Val ());            if (Loginemail = = NULL | | loginemail = = ' Mailbox ' | | loginemail = = "") {                $ (". Smtwarning"). Empty (). Text ("Your email account forgot to enter");                                }                else{                    if (Stremail.search (/^\w+ (-\w+) | ( \.\w+)) *\@[a-za-z0-9]+ ((\.| -) [a-za-z0-9]+] *\. [a-za-z0-9]+$/)! =-1) {                        $ (". Smtwarning"). empty ();                        return true;                    }                    else {                        $ (". Smtwarning"). Empty (). Text ("Please enter the correct mailbox format");}}}        

2. Write in $ (document). Ready (function ())

Login Box Form Verify   var $loginEmail = $ ("input[name= ' email ']");   var $stmWarning = $ (". smtwarning");   $loginEmail. blur (function () {       var loginemail = $.trim ($ ("input[name= ' email ']"). Val ());       if (Loginemail = = NULL | | loginemail = = ' Mailbox ' | | loginemail = = ') {            $stmWarning. Empty (). Text ("Your email account forgot to enter");       } else {          if (Loginemail.search (/^\w+ (-\w+) | ( \.\w+)) *\@[a-za-z0-9]+ ((\.| -) [a-za-z0-9]+] *\. [a-za-z0-9]+$/)! =-1) {              $stmWarning. empty ();              return true;           } else {              $stmWarning. Empty (). Text ("Please enter the correct mailbox format");}}  );
