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, $resource) {
//controller which has resource to populate the table
}
这是对EpokK答案的扩展。
我有同样的问题,必须调用一个作用域函数时,enter被推到一个输入字段。但是,我还想将输入字段的值传递给指定的函数。这是我的解决方案:
app.directive('ltaEnter', function () {
return function (scope, element, attrs) {
element.bind("keydown keypress", function (event) {
if(event.which === 13) {
// Create closure with proper command
var fn = function(command) {
var cmd = command;
return function() {
scope.$eval(cmd);
};
}(attrs.ltaEnter.replace('()', '("'+ event.target.value +'")' ));
// Apply function
scope.$apply(fn);
event.preventDefault();
}
});
};
});
在HTML中的用法如下:
<input type="text" name="itemname" lta-enter="add()" placeholder="Add item"/>
向EpokK的回答致敬。
