php - $.post() Jquery post 无法使用 new array() 到 PHP

Question

我将以下 jquery 发布到 php 页面。 php 页面上的 var_dump($_POST); 返回 null，但如果我这样做:

$.post("test.php", {"script": script} );

一切正常。

我不想这样做的原因是因为数组可以有可变参数。有什么帮助吗？

var arr = new Array();
arr["script"] = scrip;
arr["account"] = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d4b9b5ac94bcbba0b9b5bdb8fab7bbb9" rel="noreferrer noopener nofollow">[email protected]</a>";
arr["accounttag"] = "TH";


if (follow != "")
    arr["followtag"] = follow;
if (join != null)
    arr["join"] = join;

$.post("test.php", arr );

    //{"script" : script, "account" : "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="503d312810383f243d31393c7e333f3d" rel="noreferrer noopener nofollow">[email protected]</a>", "accounttag" : "TH"}  
    //works if used instead of arr

    ///test.php

    var_dump($_POST)
    array 0{null};

你的var arr应该是一个Object而不是Array。

尝试如下:

var data = {
    script: scrip,
    account: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="8fe2eef7cfe7e0fbe2eee6e3a1ece0e2" rel="noreferrer noopener nofollow">[email protected]</a>",
    accounttag: "TH"
}

if (follow != "")
    data.followtag = follow;
if (join != null)
    data.join = join;

$.post("test.php", data);
