网上下了个jq插件，输入框绑定了click事件，但是我自己写的angular脚本也在同一个输入框上用了ng-keydown。。。我以为是angular的keydown处理函数会执行，结果没效果。。。但是我又不能把插件的click事件处理函数给去掉，因为要用到它的功能。。。不知道怎么处理这种情况
<body ng-app="myApp" ng-controller="MyController">
<!--自定义指令: 限制输入框中只能是1到100之间的数值--> <input type="text" score> <script type='text/javascript' src="angular.js"></script> <script type="text/javascript">
angular.module('myApp',[])
.directive('score', function () { return { link : function (scope, elements, attrs, controller) { //在显示之前执行, 只执行一次 //得到input //console.log('link()',elements); var input = elements[0] //给input绑定keyup的监听回调函数 input.onkeyup = function () { //读取input的value, 判断是否合法 var score = input.value.trim() //如果合法, background为white if(score==='' || (score*1>=1&&score*1<=100)) { input.style.background = 'white' } else { //否则为red input.style.background = 'red' } } } } }) .controller('MyController', function($scope){ });
</script></body></html>
The keyup event I just wrote today, keydown is similar
You can’t write it like this, The first choice is require: '?ngModel', Then get the value of the text box ngModel.$modelValue instead of input.value, There is also no need for elements [0], element represents jquery The thinking is too serious. . .
