angularjs - Angular - when calling a function from ng-show and passing a parameter into it - the parameter becomes undefined -

i having problem angular when call function ng-show hide/show element parameter pass undefined function.

i don't know if it's because using php print html highly doubt it. there no other option me use it.

what possible reason why undefined?

<div ng-app="app">         <div ng-controller="myctrl">     ...     <?php     ...     echo '<li ng-show="toggle(' .$type . ')"></li>' //$type not undefined     ...      ?>        ...     </div>     </div> 

js:

app.controller('myctrl', function($scope) {  $scope.toggle = function(type){  console.log(type); //undefined ...  }  }); 

i can provide more info if needed.

if goal pass literal string toggle function, forgot add quotes around $type:

echo '<li ng-show="toggle(\'' .$type . '\')"></li>' 

so, if php variable $type has value 'hello', generated html code be

<li ng-show="toggle('hello')"></li> 

without quoted, generated html code

<li ng-show="toggle(hello)"></li> 

which means javascript function called $scope.hello argument, undefined.
