使用jsGrid进行服务器端筛选涉及到以下几个步骤:
controller
,以便在进行筛选时发送请求到服务器端。以下是一个详细的示例,展示了如何实现这一过程。
假设你使用的是Node.js和Express来设置服务器端API。你需要创建一个API端点来处理筛选请求。
const express = require('express');
const app = express();
const port = 3000;
// 示例数据
const data = [
{ id: 1, name: "John", age: 25 },
{ id: 2, name: "Jane", age: 30 },
{ id: 3, name: "Bob", age: 35 },
// 更多数据...
];
app.get('/api/data', (req, res) => {
const { name, age } = req.query;
// 进行筛选
let filteredData = data;
if (name) {
filteredData = filteredData.filter(item => item.name.includes(name));
}
if (age) {
filteredData = filteredData.filter(item => item.age == age);
}
res.json(filteredData);
});
app.listen(port, () => {
console.log(`Server is running on http://localhost:${port}`);
});
在前端,使用jsGrid并配置controller
来发送筛选请求到服务器端API。

在服务器端API中,处理传入的筛选参数并返回相应的数据。上面的服务器端代码已经展示了如何处理筛选参数。
