javascript - document.getElementById().value does not work in form's hidden field asp.net web pages -


i created simple website using asp.net web pages (using razor markup). have form 2 hidden fields: latitude , longitude. in js script use html5 geolocation api user's location expressed in degrees (latitude , longitude) , try assign these values 2 hidden fields in form before sending them out server.

the problem use getelementbyid().value method assign these value , not seem work! can print out values in same place in script using simple alert() message i'm pretty sure it's getelementbyid().value doesn't work.

here's code form:

<form  id="locationform" method="post" action="" onsubmit="return getlocation()"> search cinema showings in area<br /> <input type="hidden" name="latitude" id="latitude" value="" /> <input type="hidden" name="longitude" id="longitude" value=""/> <input type="submit" value="submit" class="submit"/> </form>

and here's code script:

<script> function getlocation() {     if (navigator.geolocation) {         navigator.geolocation.getcurrentposition(showposition);     }     else {         alert("geolocation not supported browser.");      } } function showposition(position) {      var lat = position.coords.latitude;     alert("lat is: " + lat);      document.getelementbyid('latitude').value = position.coords.latitude;      document.getelementbyid("longitude").value = position.coords.longitude; }

i apologize english ... native language portuguese / brazil.

i have same problem. had check codes in many browsers , windows versions.

document . getelementbyid (hiddenformvariable) . value = 'string' not run in ...
