javascript - Click a button to change the text of text input -

i have part of code in codeigniter controller named 'ajaxcalls' :

public function show_contact_persons($client_id) {         $data['contact_persons'] = $this->common_model->select_records('ci_contact_persons', 'client_id', $client_id);         //dump($data);      function echoarray ($array) {         foreach ($array $key => $value)         {             if ( true == is_array($value) )             {                echoarray($value);             }             else             {                 if ($key == 'contact_person_name') {                     echo '<input type="button" value="'.$value.'" onclick="changecontact(987)" /><br />';                 }             }         }     }     echoarray($data);  } 

and js part @ page calling php file :

function changecontact(contact_name) {              document.getelementbyid('contact_person').value = contact_name;         } 

i put number '987' in example because code works numbers. when put text inside bracket, or want :

onclick="changecontact('.$value.')" 

then script doesn't work. numbers. should change make work strings?

you close.

use instead :

onclick="changecontact("'.$value.'")" 

whats happening js rendering changecontact(stringvalue); expecting defined variable.

adding quotations pass function string render : changecontact("stringvalue");
