AngularJS : Transclude a single input element into a directive template without using a container -


i create wrapper input field input-help tool tip inside of it.

i using angular 1.0.7, if it's significant.

i'm using transclude: true, along isolate scope in order allow errors @ several different fields simultaneously, , still maintain ng-model reference external $scope.

the problem:

when use directive on input element, input element doesn't clone('transclude') directive template.

as result of getting empty div element @ dom, ng-transclude attribute.

plunk: http://plnkr.co/edit/vfb9ih6x2nbmwhaes3qh?p=preview

code:

<input data-my-validate-input data-value-required="true" type="password" class="loginitem" placeholder="password" name="password" data-ng-model="formdata.password" data-display-name="password">

however when wrap input element in span or div, child input element transcended fine, don't reference correct external ng-model(ctrl) @ directive.

<span data-my-validate-input data-value-required="true" data-display-name="password">       <input type="password" class="loginitem" placeholder="password" name="password" data-ng-model="formdata.password" >     </span>

full code(the logic inside link function not relevant problem, preferred post full code)

directive('myvalidateinput', function() {     return {         require: 'ngmodel',           restrict: 'a',           transclude: true,           scope: {             displayname: '@',             valuerequired: '@',             maxlength: '@',             minlength: '@',             minletters: '@',             minnumbers: '@'           },           template: '<div class="validationcontainer">\                       <div ng-transclude></div>\                       <div class="input-help">\                         <h4>{{fielderrordisplay}}</h4>\                         <ul>\                           <li data-ng-repeat="rule in requirementspec" ng-class="rule.class">\                               {{rule.msg}}\                           </li>\                         </ul>\                       </div>\                     </div>',          replace: true,          link: function(scope, elm, attrs, ctrl) {                  var validator = function(viewvalue){                           if(scope.valuerequired && viewvalue.length == 0 && (!scope.maxlength && !scope.minlength && !scope.minletters && !scope.minnumbers)){                     scope.valid = false;                       scope.fielderrordisplay = scope.fieldname + ' required';                   }                   else{                         scope.fielderrordisplay = scope.fieldname + ' must meet following requirements: ';                         scope.requirementspec = [];                         if(scope.minlength){                           var itemvalidity = viewvalue.length >= scope.minlength;                           scope.valid = !itemvalidity ? false : scope.valid;                           var item = {                             'msg' : 'must @ least ' + scope.minlength + ' characters long',                             'class' : itemvalidity ?

the solution: $transclude takes compiled content of element, not element self.

obviously lack understanding of significant detail in implementation.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/...
