javascript - How to make HTML form fields automatically change when an option selected on a select field -

-

let's have form in codeigniter project.

<?php echo form_open(); ?>     <select>         <?php foreach($status_list $status): ?>         <option value="<?php echo $status->id; ?>"><?php echo $status->name; ?></option>         <?php endforeach; ?>     </select>     <!-- show if status type is, let's "e" -->     <input type="text" name="e_happened">     <!-- show if status type is, let's "s" -->     <input type="text" name="s_happened"> <?php echo form_close(); ?>

what want if user select 1 status, according it's type, show text field input.

i've made way type of status this: http://localhost/myapp/index.php/status/type/{status_id} users can pass status id , "echo" type of status.

i want receive html page via javascript method , show text input fields. how do that?

thank you. :)

as have jquery tag, suggest this:

$('select').change(function(){     var inp = this.value.trim();     $(this).parent().find('input[type="text"][name^="'+inp+'"]').show().siblings(':text').hide(); });

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
