Openlayers 3:以编程方式选择功能 [英] Openlayers 3: Select a feature programmatically

问题描述

我正在尝试将系统从Openlayers 2升级到Openlayers 3，但有一个我似乎无法弄清的特殊问题.

I am trying to upgrade my system from Openlayers 2 to Openlayers 3 and I have having one particular issue that I cannot seem to figure out.

我的应用程序有一个网格和一个地图，当用户单击网格时，我想在地图上选择相关点.

My application has a grid and a map and when a user clicks on the grid I want to select the relevant point on the map.

在Openlayers 2中，我使用了以下内容:

In Openlayers 2 I used the following:

self.selectControl.select(feature[0]);

我无法找到或理解如何在Openlayers 3中执行相同的操作.

I cannot find or understand how to do the same in Openlayers 3.

很明显，我有一个以编程方式找到的功能，我想在地图上(以编程方式)选择该功能！

So to be clear, I have a feature which I have found programmatically and I want to select that feature on a map (programmatically)!

我似乎无法在API中找到任何内容，但这可能是由于我不了解Openlayers所致.

I cannot seem to find anything in the APIs but that might be due to my lack of understanding as I am new to Openlayers.

推荐答案

为此，您需要执行以下操作:

To do this you need to do the following:

mySelectControl.getFeatures().clear() -> removes the selected items

mySelectControl.getFeatures().push(featureToSelect) -> selects the applied feature
