【问题描述】:
请查看我的JSFiddle
在 div mouseenter/mouseleave 上,我有一个相当古怪的交互,可以打开/关闭输入复选框。如果所述复选框设置为真,则它设置相邻输入文本字段的焦点。
我想将此交互隔离到一个指令中,这样我就可以在没有冲突的情况下进行复制。
我已经给盒子涂上了颜色以供参考
<body ng-app="ngApp" ng-controller="MainCtrl">
<div class="row">
<div class="span2 box red" leave-edit="uncheckInputBox(false)" enter-edit="checkInputBox(true)">hover</div>
<span class='span8'>
<p>red</p>
<input type="checkbox" ng-model="isChecked">
<input xng-focus='isChecked' ng-model="editingInput">
{{isChecked}}
{{editingInput}}
</span>
</div>
<div class="row">
<div class="span2 box blue" leave-edit="uncheckInputBox(false)" enter-edit="checkInputBox(true)">hover</div>
<span class='span8'>
<p>blue</p>
<input type="checkbox" ng-model="isChecked">
<input xng-focus='isChecked' ng-model="editingInput">
{{isChecked}}
{{editingInput}}
</span>
</div>
</div>
js
var app = angular.module('ngApp', [])
app.controller('MainCtrl', ['$scope', function ($scope) {
'use strict';
$scope.isChecked = false;
$scope.$watch('isChecked', function(newV){
newV && $('#name').focus();
},true);
$scope.checkInputBox = function(val) {
$scope.isChecked = val;
};
$scope.uncheckInputBox = function(val) {
$scope.isChecked = val;
};
}]);
app.directive('xngFocus', function() {
return {
link: function(scope, element, attrs) {
scope.$watch(attrs.xngFocus,
function (newValue) {
newValue && element.focus();
},true);
}
};
});
app.directive('leaveEdit', function(){
return function(scope, element, attrs) {
element.bind('mouseleave', function() {
scope.$apply(attrs.leaveEdit);
});
};
});
app.directive('enterEdit', function(){
return function(scope, element, attrs) {
element.bind('mouseenter', function() {
scope.$apply(attrs.enterEdit);
});
};
});
css
.box {
height:50px;
cursor:pointer;
color: #fff;
text-align: center;
