Question

我设置搜索，以便我可以按照我的注释标题进行搜索，但我也希望通过function calc() { //Gather columns in arrays var col5 = document.getElementsByClassName('col5'); var col6 = document.getElementsByClassName('col6'); //Start sums at 0 var sum5 = 0, sum6 = 0; //Loop through each column and add up sums for(var i = 0; i < col5.length; i++) { sum5 += parseInt(col5[i].innerHTML); } for(var i = 0; i < col6.length; i++) { sum6 += parseInt(col6[i].innerHTML); } //Store sums in total fields document.getElementById('total5').innerHTML = sum5; document.getElementById('total6').innerHTML = sum6; } 进行搜索！

subtitle

我如何在我现在的代码中实现它？

感谢您的帮助！

您也可以通过字幕进行搜索：

func updateSearchResults(for searchController: UISearchController) {

    guard let mapView = mapView,
        let searchBarText = searchController.searchBar.text else { return  }

    matchingItems = self.mapView!.annotations.filter { annotation -> Bool in
        if annotation.title!.range(of: searchBarText, options: .caseInsensitive) != nil {
            return true
        }

        if annotation.subtitle!.range(of: searchBarText, options: .caseInsensitive) != nil {
            return true
        }

        return false
    }

   self.tableView.reloadData()
}

能够通过字幕搜索
