[英]Load from database by clicking on a link
使用AngularJS功能,我可以查詢數據庫中的對象(每個對象都有一個“數字”字段)
<article class='recipe' ng-cloak ng-repeat='recipe in recipes'>
<h2>
<a data-ng-bind="recipe.number"></a>
</h2>
</article>
顯示“ recipe.number”的列表:
d024b8f1-a278-401d-9fd5-a72458a42dd8
0f647d45-607c-40a7-8dae-daea7385ea3f
49580ae2-54ea-491a-89ad-7035a8e10e0e
...
您能否建議我-如何通過單擊顯示的數字顯示另一個對象的字段(例如'recipe.text')? 謝謝。
您可以執行以下操作:
<article class='recipe' ng-cloak ng-repeat='recipe in recipes'>
<h2>
<a data-ng-bind="recipe.number" ng-click="showDetails = ! showDetails"></a>
</h2>
<div ng-show="showDetails">
<p>{{recipe.text}}</p>
</div>
</article>
當您單擊該數字時,將顯示詳細信息;當您再次單擊該數字時,它將隱藏該詳細信息。
這是你想要的嗎?
<article class='recipe' ng-cloak ng-repeat='recipe in recipes'>
<h2>
<a data-ng-bind="recipe.number">{{recipe.text}}</a>
</h2>
</article>
以Lotus91的答案為基礎:如果您想一次顯示一個食譜:
<article class='recipe' ng-cloak ng-repeat='recipe in recipes'>
<h2>
<a data-ng-bind="recipe.number" ng-click="showRecipe = recipe.text"></a>
</h2>
</article>
<div ng-if="showRecipe != ''">
<p>{{showRecipe}}</p>
</div>
或者,如果您想一次顯示多個:
<article class='recipe' ng-cloak ng-repeat='recipe in recipes'>
<h2>
<a data-ng-bind="recipe.number" ng-click="recipe.showRecipe = ! recipe.showRecipe"></a>
</h2>
<div ng-if="recipe.showRecipe">
{{recipe.text}}
</div>
</article>
