我正在开发一个程序,但我现在卡住了,试图从我的html选项中获取文本。我最近读了很多关于 plnkr 的帖子,但由于我正在使用电子和AngularJS,我不知道如何设置它。
实施例: http://plnkr.co/edit/0BzvwOIQUdfS3KfKUtcS?p=preview
在该示例中,结果应该是在单击“确定”按钮时将所选选项的文本导出到json,但它仅导出值,例如。 行动:1
导出的 json atm 。看起来像这样:
{
"keybindings": [
{
"keyString": "B",
"action": "3",
"shiftKey": true
}
]
}
但是我想要
{
"keybindings": [
{
"keyString": "B",
"action": "eraser_tool_action",
"shiftKey": true
}
]
}
我缩短了代码,但应该有81个选项。
以下是模板的代码:
<!DOCTYPE html>
<html>
<head ng-app="app">
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<div class="modal-dialog">
<form class="modal-content">
<div class="form-group">
<label>Key</label>
<select for="entry" class="form-control" ng-model="entry.actionEvent" onchange="CheckDesc(this.value);">
<option value="0">-- choose an action --</option>
<option value="1" ng-model="entry.actionEvent">eraser_tool_actionEvent</option>
<option value="81" ng-model="entry.actionEvent" >decrease_brush_size_actionEvent</option>
</select>
<div class="form-action">
<button type="button" ng-click="close()" id="cancel-entrywindow" class="btn btn-form btn-default">Close</button>
<button type="button" ng-click="addEntry(entry)" class="btn btn-form btn-primary">OK</button>
</div>
</form>
</div>
</script>
</body>
</html>
这是 script.js
var app = angular.module('controllers', ['angularModalService']);
app.controller('IndexCtrl', ['$scope', '$routeParams',
function($scope, $routeParams){
$scope.entries = db('keybindings').cloneDeep();
$scope.removeEntry = function(entry){
var query = {keyString: entry.keystring, action: entry.actionEvent, shiftKey: entry.modifier1, ctrlKey: entry.modifier2, altKey: entry.modifier3};
db('keybindings').remove(query);
$scope.entries = db('keybindings').cloneDeep();
};
}
]);
app.controller('EntryCtrl', ['$scope', 'close', '$routeParams', '$location',
function($scope, close, $routeParams, $location){
$scope.entry = {
'keyString': '',
'action': '',
"shiftKey": false,
"ctrlKey": false,
"altKey": false
};
$scope.addEntry = function(entry){
var t = $scope.entry;
alert('works');
var data = {keyString: t.keystring, action: t.actionEvent, shiftKey: t.modifier1, ctrlKey: t.modifier2, altKey: t.modifier3};
if(data === null)
{
alert('Insert something');
}
else{
db('keybindings').push(data);
}
$location.path("/");
};
$scope.close = close;
}
]);
app.controller('IndexCtrl', function($scope, ModalService) {
$scope.showModal = function() {
ModalService.showModal({
templateUrl: 'addentry.html',
controller: "EntryCtrl"
}).then(function(modal) {
modal.element.modal();
});
}
});
答案 0 :(得分:1)
ng-model
不应该在options
元素上,也不要使用onchange
函数,这也不是必需的。最好通过在控制器和放大器中使用options
数组以角度方式实现它。然后使用ng-options
指令渲染选择下拉列表。
<select for="entry" class="form-control" ng-model="entry.actionEvent"
ng-options="option.id as option.value for option in options">
<option value="0">-- choose an action --</option>
</select>
<强>代码强>
$scope.options = [
{id: 1, value: 'eraser_tool_actionEvent'},
{id: 81, value: 'decrease_brush_size_actionEvent'},
]
