ng-model does what you want. ng-model做您想要的。
<select class="select len_lg" ng-model="timeSetting.timezone">
<option value="1">(GMT-12:00) International Data Line West; </option>
<option value="2">(GMT-11:00) UTC-11; </option>
<option value="3">(GMT-11:00) Samoa;</option>
<option value="4">(GMT-10:00) Hawaii;</option>
<option value="5">(GMT-09:00) Alaska; </option>
<option value="6">(GMT-08:00) Baja California;</option>
<option value="34">(GMT-08:00) Pacific Time (US & Canada);</option>
</select>
