php - JavaScript and HTML Regex not working -


i have php page:

<?php     if($_server['request_method'] == 'post'){         echo $_post["username"];         echo $_post["password"];         echo $_post["confirm_password"];         echo $_post["email"];     } ?> <!doctype html> <html> <head>     <title>wordcat signups</title>     <script type="text/javascript" src="signup_validate.js"></script> </head> <body>     <form action="" method="post">         username:<br><input type="text" name="username" placeholder="username" onkeyup="check_username();"><span id="check_username"></span><br>         password:<br><input type="password" name="password" placeholder="password" onkeyup="check_password();"><span id="check_password"></span><br>         confirm password:<br><input type="password" name="confirm_password" placeholder="confirm password" onkeyup="check_passwords();"><span id="check_passwords"></span><br>         email:<br><input type="email" name="email" placeholder="email" onkeyup="check_email();"><span id="check_email"></span><br>         <input type="submit" name="submit" value="signup"></br>     </form> </body> </html>

i have javascript meant check fields:

function check_username(){     var username = document.getelementsbyname("username")[0].value;     var pattern = /^[\w[^!\"\#$%&\'()*+,\-.\/:;<=>?@\[\\\]^_`{|}~]]{1,32}$/;     if(pattern.test(username)){         document.getelementbyid("check_username").innerhtml = "username valid.";     } else {         document.getelementbyid("check_username").innerhtml = "username invalid. should contain letters, numbers, , underscores, have maximum of 32 characters.";     } } function check_password(){     var password = document.getelementsbyname("password")[0].value;     var pattern = /^(?=.*[a-z])(?=.*[a-z])(?=.*\d)([a-za-z0-9!\"\#$%&\'()*+,\-.\/:;<=>?@\[\\\]^_`{|}~]{6,})$/;     if(pattern.test(password)){         document.getelementbyid("check_password").innerhtml = "password valid.";     } else {         document.getelementbyid("check_password").innerhtml = "password invalid. should have @ least 6 characters, , @ least 1 number, uppercase, , lowercase character.";     } } function check_passwords(){     var password = document.getelementsbyname("password")[0].value;     var confirm_password = document.getelementsbyname("confirm_password")[0].value;     if(password == confirm_password){         document.getelementbyid("check_passwords").innerhtml = "passwords match";     } else {         document.getelementbyid("check_passwords").innerhtml = "passwords not match.";     } }

however, javascript, username , confirm password tests working, password regex not. when key in valid passwords. regex can found here link , correct tests. when use browser regex fails valid passwords online!

i don't see reason use single regex complex condition yours (other showing off regex-fu)...

if(     password.length >= 6 &&  // @ least 6 characters     /[0-9]/.test(password) && // @ least 1 number     /[a-z]/.test(password) && // @ least 1 lowercase character     /[a-z]/.test(password) // @ least 1 lowercase character ) {     // yay :) }

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
