下面显示了一个按钮:
<a class="action submit btn btn-danger btn-lg pull-right" onclick="return simpan_akhir();"><i class="glyphicon glyphicon-stop"></i> Selesai Ujian</a>
函数如下:
simpan_akhir = function() {
if (confirm('Anda yakin akan mengakhiri tes ini..?')) {
var f_asal = $("#_form");
var form = getFormData(f_asal);
$.ajax({
type: "POST",
url: base_url + "adm/ikut_ujian/simpan_akhir/" + id_tes,
data: JSON.stringify(form),
dataType: 'json',
contentType: 'application/json; charset=utf-8'
}).done(function(r) {
if (r.status == "ok") {
window.location.assign("<?php echo base_url(); ?>adm/sudah_selesai_ujian/" + id_tes);
}
});
return false;
}
为什么单击按钮时不调用 ajax？ 这是 adm/ikut_ujian/simpan_akhir 里面的内容:

$a['status'] = "ok";
j($a);
exit;
一开始我以为ajax调用不成功是因为查询不通，果然是查询不通。然后我尝试删除一些代码行并只返回 $a['status']="ok"，但它不起作用。

这对我有用。
