Question

我正在尝试通过单击按钮刷新验证码。但是它不会进入函数本身。我错过了什么吗？这是我的controller.js代码：

$scope.goCaptcha = function()
{
console.log('entered');
var alpha = new Array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '1', '2', '3', '4','5','6','7','8','9','0');

var i;
for (i = 0; i < 6; i++) {
    var a = alpha[Math.floor(Math.random() * alpha.length)];
    var b = alpha[Math.floor(Math.random() * alpha.length)];
    var c = alpha[Math.floor(Math.random() * alpha.length)];
    var d = alpha[Math.floor(Math.random() * alpha.length)];
    var e = alpha[Math.floor(Math.random() * alpha.length)];
    var f = alpha[Math.floor(Math.random() * alpha.length)];
    var g = alpha[Math.floor(Math.random() * alpha.length)];
}
var code = a + ' ' + b + ' ' + ' ' + c + ' ' + d + ' ' + e + ' ' + f + ' ' + g;

document.getElementById("main-captcha").value = code
}

这是我的HTML代码：

 <label class="item item-input" id="login-input3">
     <input type="text" readonly id="main-captcha">
    <button type="submit" class="button button-small" ng-click="goCaptcha()">Refresh</button>
 </label>

确实有效。您可能在HTML中缺少ng-controller="yourCtrlName"。或者检查是否有其他愚蠢的错误。

工作片段：

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.goCaptcha = function() {
    console.log('entered');
    var alpha = new Array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0');

    var i;
    for (i = 0; i < 6; i++) {
      var a = alpha[Math.floor(Math.random() * alpha.length)];
      var b = alpha[Math.floor(Math.random() * alpha.length)];
      var c = alpha[Math.floor(Math.random() * alpha.length)];
      var d = alpha[Math.floor(Math.random() * alpha.length)];
      var e = alpha[Math.floor(Math.random() * alpha.length)];
      var f = alpha[Math.floor(Math.random() * alpha.length)];
      var g = alpha[Math.floor(Math.random() * alpha.length)];
    }
    var code = a + ' ' + b + ' ' + ' ' + c + ' ' + d + ' ' + e + ' ' + f + ' ' + g;

    document.getElementById("main-captcha").value = code
  }
});

ng-click不会自动输入功能
