javascript - Get DOM element of watch event in Angular.JS -


i have 2 select boxes on web page, , when state chosen first 1 use angular load in options second. when page first loads, second select box has 1 item, select state... , after first item changed, want change select....

is possible access dom element through angular make change, or must use full-on jquery selector in example:

$scope.$watch('state', function() {     $http.get('institutions?state=' + $scope.state).success(function(institutions) {         $scope.institutionoptions = institutions;          // avoid jquery selector if possible...         $('[name=institution_id] option:first').html('select...');     }); }, true);

i think should stick data binding as possible. bind $scope.message:

js:

$scope.message = "initial message"

html:

<select ng-model="selected" ng-options="c.o c in options">   <option value="">{{message}}</option> </select>

when receive data, change message:

$scope.message = "select..."; $scope.options = [{o:"option1"},{o:"option2"}, {o:"option3"} ]

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
