Question

我想创建一个只匹配FALSE的指令。

任何时候编译都会找到这种类型的输入，我希望我的指令适用。我不想在元素中添加任何内容（额外的类或属性）。

这可能吗？我该怎么做？

SOLUTION：

为了后人，我包括我的solution：

＆＃13;

<input type="password"

＆＃13;

angular.module('controls', [])

.directive('type',
  function() {
    return {
      restrict: 'A',
      compile: function(element, attributes) {
        if (element.prop('nodeName') === 'INPUT' && attributes.type === 'password') {
          return function link(scope, element, attributes, controller) {
            element.on('keypress', function(event) {
              var s = String.fromCharCode(event.which);
              if (s.toUpperCase() === s && s.toLowerCase() !== s && !event.shiftKey) {
                element.addClass('capslock');
              } else {
                element.removeClass('capslock');
              }
            });
          };
        }
      }
    };
  });

＆＃13;

.capslock {

您可以尝试为type属性添加指令，只在元素为<input>且type为＆＃34;密码＆＃34; <时才执行链接功能/ em>的

.directive('type', function() { return { restrict: 'A', compile: function(tElement, tAttrs) { if (tElement.prop('nodeName') === 'INPUT' && tAttrs.type === 'password') { return function postLink(scope, iElement, iAttrs, controller) { // etc }; } } }; })

Plunker演示，其中指令将＆＃34; red＆＃34; 类添加到元素〜http://plnkr.co/edit/EurHOzKiloE6B0QQSwAY?p=preview

我会在<?php header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: GET, POST'); header("Access-Control-Allow-Headers: X-Requested-With"); $response = "Hmmm... Please contact the webmaster at contact@vahana.io as it seems that there is a problem with submitting this form. Error x02"; echo json_encode(['response' => $response]); ?>上放置一个transclude指令，然后在编译transclude之前添加指令。

我没有测试过上面的内容，但它会是那样的。
