使用事件侦听器的AngularJS自定义指令

Question

我正在尝试创建一个自定义指令,其中包含一个文本框,当用户单击按钮时,该文本框会显示,展开和聚焦.当用户点击扩展文本框时,它应该最小化,消失,然后显示原始按钮.这是我到目前为止所拥有的:http: //jsfiddle.net/Z6RzD/152/

以下是我遇到问题的部分:

  if (htmlTxtBox.addEventListener !== undefined) { 
  console.log("first");

  htmlTxtBox.addEventListener('focus', setFocus(), false);
  //this function is automatically called even when textBox is in focus              
  //htmlTxtBox.addEventListener('blur', setNoFocus(), false);
  console.log("ifHasFocus: " + scope.showInput);
} else if (htmlTxtBox.attachEvent != undefined) {
  console.log("second");
  htmlTxtBox.attachEvent('onfocus', setFocus());
  htmlTxtBox.attachEvent('onblur', setNoFocus());
} else {
  console.log("third");
  htmlTxtBox.onmouseover = setFocus();
  htmlTxtBox.onmouseout = setNoFocus();
}

以及与事件侦听器一起运行的相应函数:

function setFocus()  {
        scope.$apply('showInput = true');
        console.log("setFocus: " + scope.showInput);    
    }
function setNoFocus(){
  scope.$apply('showInput = false');
  console.log("setNoFocus: " + scope.showInput);
}

我的问题是setFocus和setNoFocus函数无论如何运行.如何在文本框聚焦或模糊时将这些函数构建到它们运行的​​位置？我感谢任何帮助.谢谢!

试试这个:

myApp.directive('replybox', function($timeout) {
    var linkFn = function(scope, element, attrs) {       
        scope.showInput = false;

        var button = element.find('button');        
        var input = element.find('input');

        button.bind("click", function() {
            scope.showInput = true;
            scope.$apply();

            input[0].focus();
            input.css({"width":"300px","transition":"1s"});            
        });

        input.bind('blur', function() {
            scope.showInput = false;            
            $timeout(function() { scope.$apply(); }, 1000);

            input.css({'width':'0px', 'transition':'1s'});
        });
    };    
...
