php - jquery: appendTo lose stripslashes in a hidden field -


am working on front-end utility creating forms using php , jquery; can add several specific fields later used on form , parameters stored in dinamically inserted hidden fields of graphic interface. working fine far stumbled in problem code adds fields display (and later parsed generate final form data); in injected div contains parameters backslashes of regex stored in hidden field stripped out. here part of code:

var fieldsnumber =1; //this determines field id of inserted feature fieldcenterhtml =   '<div class="formfieldcenterarea">'         +   '<div class="formparamcontainer"><label>default value:</label><input type="text" name="field_'+fieldsnumber+'_value" value=""/></div>'              +   '<input type="hidden" name="field_'+fieldsnumber+'_type" value="phone_number"/>'         +   '<input type="hidden" name="field_'+fieldsnumber+'_firstvalue" value=""/>'         +   '<input type="hidden" name="field_'+fieldsnumber+'_valuelist" value=""/>'         +   '<input type="hidden" name="field_'+fieldsnumber+'_hasregex" value="1"/>'         +   '<input type="hidden" name="field_'+fieldsnumber+'_regex" value="/^[(]?\d{3}[)]?\s?-?\s?\d{3}\s?-?\s?\d{4}$/"/>'          +   '<input type="hidden" name="field_'+fieldsnumber+'_hassize" value="0"/>'         +   '<input type="hidden" name="field_'+fieldsnumber+'_size" value="0"/>'     +   '<div class="formparamcontainer"><label>is required:</label><input type="checkbox" name="field_'+fieldsnumber+'_isrequired"  value="1" /></div>';         +   '</div> <!-- end formcenterfield --'+'>';  //the injecting code  fielddatahtml = fieldcenterhtml;       //insert field in dom          var element = $('<div/>', {         class: 'element',         html: fielddatahtml     }).appendto('#form-area-container');

when field got inserted in page, field_1_regex appear this:

<input type="hidden" value="/^[(]?d{3}[)]?s?-?s?d{3}s?-?s?d{4}$/" name="field_1_regex">

and loses backslashes in regular expression. suspect appendto stripping backslashes @ insertion in dom; how can go around problem?

a working example on jsfiddle.

[edit] solved out; decided posticipate population of regex field pushing empty field and, after insertion in dom using jquery isnert value.

a test of solution in jsfiddle here.

that might because backslashes should escaped in string this:

'_regex" value="/^[(]?\\d{3}[)]?\\s?-?\\s?\\d{3}\\s?-?\\s?\\d{4}$/"/>'

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
