如果我在指令模板中有一个带有ng-controller属性值的div,我该如何将其更改为变量:
original html : <div ng-controller="HomeController"> ..... </div>
directive: <my-directive some-var-name="HomeController"> ....</my-directive>
.directive('MyDirective', function(){
return {
.....
scope:
{
someVarName : "????" <-- what type? "=", "@", "&" : none seem to work
},
template: '<div ng-controller="someVarName">.....</div>'
}
});
感谢Mark解决此问题:
<select-add-new select-model="$parent.selectedFrontAxle" text="add new"
select-phrase="Front Axle Type" preselected-filter="Front"
label-name="Front Axle" open-dialog="Front"
select-options="axleTypes" var-ctrl="AxleTypesCtrl"></select-add-new>
.directive('selectAddNew', function () {
return {
replace: true,
restrict: "E",
scope: {
selectModel: "=",
selectOptions:"=",
labelName: "@",
preselectedFilter: "@",
selectPhrase: "@",
text: "@"
},
compile: function(tElement, attrs) {
var div = tElement.find('#ctrlId');
div.attr('ng-controller', attrs.varCtrl);
},
template: '<div>' +
'<div class="local-label">{{labelName}}: </div>' +
'<name-value-select-control select-phrase="{{selectPhrase}}" selected-item="selectModel" preselected-filter="{{preselectedFilter}}" options="selectOptions"></name-value-select-control>' +
'<div id="ctrlId">' +
'<div txt-add-new text="{{text}}" action="openDialog(\'Front\')" style="display: inline-block"></div>' +
'</div>' +
'</div>'
};
})

以下是plunker:

以下是问题:
我将两个指令合并为一个超级指令。如果你去app.js,指令'selectAddNew',你会看到从底部开始的第三行:
......... action =“openDialog(\'Front \')”..................
但这是硬编码的。我尝试了每一种方式使它成为超级指令中的一个动作,但我最接近的是打开整个表单窗口的公共对话框。有什么想法吗?

模板在编译阶段编译,此时someVarName
不可用(它是指令范围的属性,尚未设置)。相反,在编译函数中,我们可以向ng-controller
添加div
属性,并将其设置为some-var-name
属性的值:
app.directive('myDirective', function() {
return {
restrict: 'E',
template: '<div>....</div>',
compile: function(tElement, attrs) {
var div = tElement.find('div');
div.attr('ng-controller',attrs.someVarName);
}
}
});

我认为您正在寻找@:scope:{someVarName:'@'},template:'<div>Hello {{someVarName}}</div>
