Angular指令不適用於click事件
[英]Angular directive doesn't work with click event
問題描述
如何將帶有單擊處理程序的按鈕添加到指令中的模板？
我使用此腳本，但在控制器中不起作用。
我是新手。 我從https://github.com/khan4019/tree-grid-directive/blob/master/README.md獲得了此腳本

2 個解決方案

我看到您在指令中向模板添加了三個按鈕：
<button class=\"btn btn-sm btn-info\" ng-click=\"handleActions.edit(row)\">\
<i class=\"glyphicon glyphicon-edit\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-click=\"createWindow()\">\
<i class=\"glyphicon glyphicon-plus\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-show=\"row.deletable\" ng-click=\"handleActions.delete(row)\">\
<i class=\"glyphicon glyphicon-remove\"></i>\
</button>\
並且您已向其添加ng-click。 現在，將在ng-click事件上執行的功能應該是scope的一部分。
在這種情況下，定義指令時，您需要在定義中聲明作用域：
scope: {
treeData: '=',
colDefs:'=',
expandOn:'=',
onSelect: '&',
initialSelection: '@',
treeControl: '='
}
因此，您已經創建了Isolated范圍 。 這意味着函數createWindow ， edit和delete必須是指令范圍的一部分。
您有兩種選擇，一種骯臟的方式：將函數復制到指令：
module.directive('treeGrid', [
[...]
<button class=\"btn btn-sm btn-info\" ng-click=\"edit(row)\">\
<i class=\"glyphicon glyphicon-edit\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-click=\"createWindow()\">\
<i class=\"glyphicon glyphicon-plus\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-show=\"row.deletable\" ng-click=\"delete(row)\">\
<i class=\"glyphicon glyphicon-remove\"></i>\
</button>\
[...]
scope.user_clicks_branch = function(branch) {
if (branch !== selected_branch) {
return select_branch(branch);
}
};
// new code
scope.createWindow = function() {
// your createWindow code
}
scope.edit = function(row) {
// your edit row code
}
scope.delete = function(row) {
// your delete row code
}
[...]
]);
}).call(this);
或者，您可以使用表達式綁定（＆）將處理程序作為參數傳遞（就像代碼對onSelect處理程序所做的一樣）：
module.directive('treeGrid', [
[...]
<button class=\"btn btn-sm btn-info\" ng-click=\"onEdit(row)\">\
<i class=\"glyphicon glyphicon-edit\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-click=\"createWindow()\">\
<i class=\"glyphicon glyphicon-plus\"></i> \
</button>\
<button class=\"btn btn-sm btn-info\" ng-show=\"row.deletable\" ng-click=\"onDelete(row)\">\
<i class=\"glyphicon glyphicon-remove\"></i>\
</button>\
[...]
scope: {
treeData: '=',
colDefs:'=',
expandOn:'=',
onSelect: '&',
createWindow: '&',
onEdit: '&',
onDelete: '&',
initialSelection: '@',
treeControl: '='
}
[...]
]);
}).call(this);
解決方案2

如果只想向列中添加一些按鈕，則可以在控制器中使用$ scope.col_def來添加列定義，如下所示：
$scope.col_defs = [{ field: "id" },
{
field: "Action",
cellTemplate: $templateCache.get('buttonTemplate.html'),
cellTemplateScope: {
doSomething: function () {
console.log('call your function here, or put what you want to do');
}
}
}];
可以在控制器內部的視圖中定義“ buttonTemplate.html”，並在treeGrid中定義col_defs：
<div ng-controller="HomeController">
<script type="text/ng-template" id="buttonTemplate.html">
<button class="btn btn-sm btn-danger" ng-click="cellTemplateScope.doSomething()">Do Something</button>
</script>
<tree-grid tree-data="yourTreeData" col-defs="col_defs"></tree-grid>
</div>
因此，在這種情況下，它將在您的列內運行此模板，並在您單擊按鈕時調用doSomething（）函數。
