Question

我想将以AJAX jquery编写的函数的参数（source_lead）传递给以节点js编写的服务器部分的另一个函数。我该怎么做？

AJAX jQuery：

$("#importdata").on('click', function () {
    var source_lead = $("#source").val();
    $.get("/import", function (data) {

        $("#message").show().html(data['success']);
    });
});

Node JS：

}).get('/import', function (req, res, next) {
// var source_lead = fs.readFileSync('source.txt', 'utf-8');
var csvfile = __dirname + "/../public/Tables/leads.csv";
var stream = fs.createReadStream(csvfile);
var products = [];
var csvStream = csv()
    .on("data", function (data) {
        var item = new Product({
            name: data[13],
            age: data[5],
            phone: data[14],
            email: data[15],
            date: data[1],
            // source: source_lead
        });

        item.save(function (error) {
            console.log(item);
            if (error) {
                throw error;
            }
        });

    }).on("end", function () {

    });

stream.pipe(csvStream);
res.json({success: "Data imported successfully.", status: 200});
})

1）客户端

$("#importdata").on('click', function () {
    var source_lead = $("#source").val();
    $.get("/import?source_lead=json", function (data) {

        $("#message").show().html(data['success']);
    });
});

2）NodeJ ....

}).get('/import', function (req, res, next) {
    let source_lead = req.query.source_lead
})

您可以通过ajax调用传递query params并将其接收到nodejs api get端点。

JavaScript

 $.get("/import?data=myData", function (data) {

        $("#message").show().html(data['success']);
    });

NodeJS

}).get('/import', function (req, res, next) {
var data = req.query.data; // Query param data

....

将参数从AJAX jQuery传递到节点js
