Javascript 如何在Angular.js中将模型传递给指令?
我试图弄清楚如何在指令和中继器之间创建双向绑定。我一直在尝试在互联网上找到的各种东西。这是我现在拥有的,但它不会将item.myDate传递到需要它的模板Javascript 如何在Angular.js中将模型传递给指令?,javascript,angularjs,Javascript,Angularjs,我试图弄清楚如何在指令和中继器之间创建双向绑定。我一直在尝试在互联网上找到的各种东西。这是我现在拥有的,但它不会将item.myDate传递到需要它的模板 app.directive("mydirective", function(){ return { restrict:'E', scope:{dateModel: "&"}, template:'<input class="date" ng-model="{{dateModel}}"&g
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: "&"},
template:'<input class="date" ng-model="{{dateModel}}">',
};
});
这应该怎么做
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: "&"},
template:'<input class="date" ng-model="{{dateModel}}">',
};
});
HTML
<tr ng-repeat="item in items">
<td>
<mydirective dateModel="item.myDate"></mydirective>
</td>
</tr>
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: "&"},
template:'<input class="date" ng-model="{{dateModel}}">',
};
});
<tr ng-repeat="item in items">
<td>
<mydirective myDate="item.myDate"></mydirective>
</td>
</tr>
JS
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: "&"},
template:'<input class="date" ng-model="{{dateModel}}">',
};
});
app.directive(“mydirective”,function()){
返回{
限制:'E',
作用域:{dateModel:&“},
模板:“”,
};
});
更改此将起作用:范围:{dateModel:“=”}。更改此将起作用:范围:{dateModel:“=”}。更改此将起作用:范围:{dateModel:“=”}。更改此将起作用:范围:{dateModel:“=”}。应该是:
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: "&"},
template:'<input class="date" ng-model="{{dateModel}}">',
};
});
app.directive("mydirective", function(){
return {
restrict:'E',
scope:{dateModel: '@'},
template:'<input class="date" ng-model="dateModel">',
};
});
app.directive(“mydirective”,function()){
返回{
限制:'E',
作用域:{dateModel:'@'},
模板:“”,
};
});
如果您希望您的指令使用与指令模板中使用的名称不同的名称(例如myDate),则应如下所示:
app.directive("mydirective", function(){

template:'<input class="date" ng-model="{{dateModel}}">',
