使用淘汰赛 JS ko.utils.arrayFilter 设置标记可见 [英] Set marker visible with knockout JS ko.utils.arrayFilter

问题描述

大家好，我正在尝试创建一个应用程序，在完成淘汰搜索时设置适当的标记可见.

Hello guys I am trying to create an app that sets the appropriate markers visible when a knockout search is being done.

基本上是应用程序.当有人搜索其下方的列表时，过滤该列表并仅使与过滤器列表关联的标记在地图上可见.我创建了一个 ko.utils.arrayFilter 并且我试图只设置 item.marker.setVisible(true)

Basically the app is. When someone does a search the list that is bellow it, filters the list and makes only the markers that are associated with the filter list visible on the map. I have created a ko.utils.arrayFilter and I am trying to set only the item.marker.setVisible(true)

推荐答案

你只需要设置标记的可见性来匹配是否找到:

All you need is to set the visibility of the marker to match whether it is found:

if (!filter) {
  // this is new
  ko.utils.arrayForEach(self.listLoc(), function (item) {
    item.marker.setVisible(true);
  });
  return self.listLoc();
} else {
  return ko.utils.arrayFilter(self.listLoc(), function(item) {
    var result = (item.title.toLowerCase().search(filter) >= 0)
    item.marker.setVisible(result); // this is a new line
    return result;
  });
}

工作小提琴.

注意:除非您支持特别旧的浏览器，否则您可以使用 数组过滤器方法 而不是 Knockout 的 arrayFilter util，以及 .foreach 而不是 arrayForEach.

Note: unless you're supporting particularly old browsers, you can use the Array filter method rather than Knockout's arrayFilter util, and .foreach instead of arrayForEach.
