我正在使用JQuery3。我在import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
public class ReadData {
public static void main(String[] str) {
readData();
}
public static void readData() {
List<SolidStateDrive> ssd = new ArrayList<>();
try (BufferedReader br = new BufferedReader(new FileReader("SSD.txt"))) {
ssd = br.lines().map(s-> {
String[] tmp = s.split("\\s+");
return new SolidStateDrive(tmp[0], tmp[1], Integer.parseInt(tmp[2]));
}).collect(Collectors.toList());
} catch (IOException ex) {
ex.printStackTrace();
}
ssd.stream().forEach(System.out::println);
}
}
class SolidStateDrive {
String brand;
String model;
int capacityInGB;
public SolidStateDrive(String brand, String model, int capacityInGB) {
super();
this.brand = brand;
this.model = model;
this.capacityInGB = capacityInGB;
}
@Override
public String toString() {
return "SolidStateDrive [brand=" + brand + ", model=" + model + ", capacityInGB=" + capacityInGB + "]";
}
}
元素中有一个对话框。触发后，对话框将<template>插入正文。在对话框中，有一个append()元素，而我无法在其上<input>。这是代码段：
focus()我仍然可以通过其const template = $('template.dialog');
const dialog = $(template.html());
dialog.find('input').focus();
$('body').append(dialog);
访问<input>，但是，我试图仅通过使用id来访问它。我该怎么办？
