jquery - Check form for similar value before submit -


is there anyway check if similar value exist in input box

ex:

<form>   user 1   <input name="user1" value="bla1">   <input name="pass1" value="ple1">   <input name="email1" value="foo1@yy.cc">    user 2   <input name="user2" value="bla2">   <input name="pass2" value="ple1">   <input name="email2" value="foo2@yy.cc">    user 3   <input name="user3" value="bla1">   <input name="pass3" value="pla3">   <input name="email3" value="foo2@yy.cc">    <button type="submit"> </form>

the verification trigger when form submitted, alert user , add class both input similar value. input fields starts @ blank , user should input values. fields should compared type user,pass, , email

i've put wee jsfiddle you.

basically loops through every element in form, finds similar names, , if have same value marks them both. little inefficient compares b, b a, still works well.

$('form').submit(function(event) {     var ok = true,         $form = $(this),         $inputs = $(this).find('input')     $inputs.removeclass('error')     $inputs.each(function() {         var $src = $(this)          //get name of element, , strip off number         var name = $(this).attr('name').replace(/[0-9]/g,'')          //filter inputs down ones name starts same         $inputs.not(this).filter('[name^="' + name + '"]').each(function() {            if($src.val() == $(this).val()) {                 ok = false                 $(this).addclass('error')                 $src.addclass('error')             }         })     })     if(!ok) event.preventdefault() })

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
