Jquery移动/ JavaScript问题

我无法通过数据的各种值正确循环“获取”，它应该发送

... CMD = PC＆安培;数据= 06464ff

... CMD = PC＆安培;数据= 16464ff

... CMD = PC＆安培;数据= 26464ff

i = 0;
do {
    setTimeout(function () {
        $.get('send.php', {
            ip: ip,
            id: id,
            port: port,
            cmd: "PC",
            data: i + "6464ff"
        }).done(function (response) {
            if (response.indexOf("PC") === 0) {
                response = response.replace("PC", "");
            } else {
                $("#ERROR").html(response);
                response = currentvm;
            }
        });
    }, 2000 * i);
    i++;
}
while (i < 255);

我得到的只是

... CMD = PC＆安培;数据= 2556464ff

有关如何继续的任何想法或建议。

谢谢。

使用闭包应解决您的问题：

do {
    (function (i) {
        setTimeout(function () {

            $.get('send.php', {
                ip: ip,
                id: id,
                port: port,
                cmd: "PC",
                data: i + "6464ff"
            }).done(function (response) {
                if (response.indexOf("PC") === 0) {
                    response = response.replace("PC", "");
                } else {
                    $("#ERROR").html(response);
                    response = currentvm;
                }
            });
        }, 2000 * i);
    }(i));
    i++;
}
while (i < 255);

可能的选择：尝试更改＆＃39; send.php＆＃39; by＆＃39; send.php？＆＃39; + i +＆＃34; 6464ff＆＃34;

或

$.get('send.php', {
    ip: ip,
    id: id,
    port: port,
    cmd: "PC",
    data: i + "6464ff",
    success: function(response) {
    if (response.indexOf("PC") === 0) {
        response = response.replace("PC", "");
    }
    else {$("#ERROR").html(response);
        response = currentvm;
    }
});

Jquery $ .get循环不起作用
