Solved : Google Map API Get the error - Cannot read property 'value' of null

I have the following JavaScript file, if I comment the file, there will be no error.

// <!-- This code tells the browser to execute the "Initialize" method only when the complete document model has been loaded. -->
$(document).ready(function () {


    var geocoder;
