javascript - Clickable cell in Angularjs -

-

i can create clickable cells in pure js, doesn't work when trying simple using angularjs: when clicking on cell, complained dum function doesn't exit. idea why? 

<!doctype html> <html> <script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script> <body>  <div ng-app="myapp" ng-controller="customersctrl">   <table>   <tr ng-repeat="x in names">     <td onclick="dum();">{{ x.name }}</td>     <td>{{ x.country }}</td>   </tr> </table>  </div>  <script> var app = angular.module('myapp', []); app.controller('customersctrl', function($scope, $http) {     $http.get("http://www.w3schools.com/angular/customers.php")     .success(function (response) {$scope.names = response.records;});     $scope.dum = function() { alert("hi you"); } });  </script>  </body> </html>

javascript onclick event binding work, not have function named dum in global scope.

it work if in html, for example:

<script>  function dum(){    alert('test')  } </script>

in angular world need use ng-click instead, bound function expression evaluated against scope. ng-click built-in directive binds click event internally , performs digest cycle after evaluating function expression bound it. example

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
