javascript - How to check the value of the "value" attribute in an <input> element? -


i have following:

<h1>request group rate</h1>      <form>         <input type="hidden" name="referrer" id="bmn">             name:          <input type="text" id="fieldname" name="name"><br> group size:          <input type="text" name="groupsize"><br>          email: <input type="email" name="email"><br>         <input type="submit" value="submit">     </form>     <script>         $(document).ready(function(){             $('input[name="referrer"]').val(document.referrer);             $(document.body).append('<div id="ready"></div>');         });     </script>

after navigating page using selenium:

    driver.findelement(by.id('requestgrouprate')).click();     driver.sleep(100);     driver.wait(function(){         return driver.findelement(by.id('ready')).then(function(){                             driver.sleep(1000);             var element =  driver.findelement(by.id('bmn'));             console.log(element.value);             assert(element.value === referrer);             done();         });     },5000);

my assertion fails. reason element.value undefined. why ? how should compare value set in input field id "bmn" ? value should set, because div id "ready" created after value set, if driver can find "ready", value input field should set..

what doing wrong ?

var ele =  driver.findelement(by.id('bmn')); ele.getattribute('value').then(function(text){   console.log('bmn value: ' + text);   assert(text === 'change expected value'); });
