Question

我试图用Ajax发布帖子请求，但它不起作用。在下面的代码中，第一个警报出现，但成功函数内的第二个警告不会出现。

    <!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="jquery-2.1.4.min.js"></script>
<script>
$(document).ready(function(){

    $("button").click(function(){

    testscore ="tryagaiDDDn"; //testvalue to enter into the mysql database
    alert("xoa"+testscore);

    $.ajax({  
    type: "POST",  
    url: "chatp.php",  
    data: { 'tryagain':tryagain },      
    success : function(data){  
      alert(data);
    } 
  });

    });
});
</script>
</head>

</html>

    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = file(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos=set()
    fstr = ''
    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,    password=password,caching=caching, check_extractable=True):
        interpreter.process_page(page)

        str = retstr.getvalue()
        fstr += str

    fp.close()
    device.close()
    retstr.close()
    return fstr

test1 =  convert_pdf_to_txt("C:\Users\User\Documents\Contract\Dental\Certificate - Dental - Assurant - 2010.pdf")

为什么这个Ajax发布请求失败？
