我想捕捉下面文本框上的回车键事件。为了更清楚地说明这一点，我使用ng-repeat填充tbody。下面是HTML:
<td><input type="number" id="closeqty{{$index}}" class="pagination-right closefield"
data-ng-model="closeqtymodel" data-ng-change="change($index)" required placeholder="{{item.closeMeasure}}" /></td>
这是我的模块:
angular.module('components', ['ngResource']);
我使用一个资源来填充表，我的控制器代码是:
function Ajaxy($scope, $resource) {
//controller which has resource to populate the table
}
当前回答
尝试
ng-keypress="console.log($event)"
ng-keypress="alert(123)"
什么也没为我做。
Strangley的例子在https://docs.angularjs.org/api/ng/directive/ngKeypress，它做ng-keypress="count = count + 1"，工作。
我找到了一个替代的解决方案，它有按Enter调用按钮的ng-click。
<input ng-model="..." onkeypress="if (event.which==13) document.getElementById('button').click()"/>
<button id="button" ng-click="doSomething()">Done</button>
其他回答
你可以使用ng-keydown, ng-keyup, ng-press，像这样。
触发一个函数:
<input type="text" ng-keypress="function()"/>
或者如果你有一个条件，比如当他按下escape(27是键) 转义代码)
<form ng-keydown=" event.which=== 27?cancelSplit():0">
....
</form>
我认为使用文档。Bind更优雅一些
constructor($scope, $document) {
var that = this;
$document.bind("keydown", function(event) {
$scope.$apply(function(){
that.handleKeyDown(event);
});
});
}
获取文档到控制器构造函数:
controller: ['$scope', '$document', MyCtrl]
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
Informe your name:<input type="text" ng-model="pergunta" ng-keypress="pressionou_enter($event)" ></input>
<button ng-click="chamar()">submit</button>
<h1>{{resposta}}</h1>
</div>
<script>
var app = angular.module('myApp', []);
//create a service mitsuplik
app.service('mitsuplik', function() {
this.myFunc = function (parametro) {
var tmp = "";
for (var x=0;x<parametro.length;x++)
{
tmp = parametro.substring(x,x+1) + tmp;
}
return tmp;
}
});
//Calling our service
app.controller('myCtrl', function($scope, mitsuplik) {
$scope.chamar = function() {
$scope.resposta = mitsuplik.myFunc($scope.pergunta);
};
//if mitsuplik press [ENTER], execute too
$scope.pressionou_enter = function(keyEvent) {
if (keyEvent.which === 13)
{
$scope.chamar();
}
}
});
</script>
</body>
</html>
你可以使用ng-keydown ="myFunction($event)"作为属性。
<input ng-keydown="myFunction($event)" type="number">
myFunction(event) {
if(event.keyCode == 13) { // '13' is the key code for enter
// do what you want to do when 'enter' is pressed :)
}
}
尝试
ng-keypress="console.log($event)"
ng-keypress="alert(123)"
