php - AJAX NS_ERROR_XPC_BAD_CONVERT_JS : Could not convert JavaScript argument jquery. js:7065

Question

我是 jQuery 和 Ajax 的新手，我遇到了一个问题。我在我的控制台上收到以下错误:

NS_ERROR_XPC_BAD_CONVERT_JS: Could not convert JavaScript argument @ http://localhost
/jquery.js:7065

为什么我会收到此错误消息？

这是我使用的代码:

function upload_file(){
    var file = document.form1.file_upload;
    var date = document.form1.date_added;
    var author = document.form1.author;
    var user = document.form1.user;
    var semester = document.form1.semester;
    var class1 = document.form1.class;
    var subject = document.form1.subject;
    $.ajax({
        type:"get",
        url:"upload_file.php",
        data:{
        "file":file,
        "date":date,
        "author":author,
        "user":user,
        "semester":semester,
        "class":class1,
        "subject":subject
        },
        success:function(result){
        $("#result").html(result);
        }
    });
    }

我在等你的回复。

PS: I Did search the forum but did not get what i want, so if i missed something, sorry in advance.

我认为问题在于您正试图将完整的对象传递给 JSON。您应该使用值而不是对象。例如，替换:

var subject = document.form1.subject;

与:

var subject = document.form1.subject.value;
