javascript - $ .post到远程网站，然后提交默认操作

function post()
{
   var cvs = $('#client-nbr').val();
   var cs = $('#cs').val();
   $.post('http://sitea.com/a.php',{postcvs:cvs,postch1:cs});
   return false;
}

调用函数onsubmit：

<form action="http://siteb.com/b.php" method="post" id="formID" onsubmit="post()">
  <input type="text" name="client-nbr" id="client-nbr" /> <br>
  <input type="text" name="cs" id="cs" /> <br>
  <button type="submit" name="submit" id="submit">subscribe</button>
</form>

我想等function post()完成发布后再提交默认操作吗？

最佳答案

<form action="http://siteb.com/b.php" method="post" id="formID">
    <input type="text" name="client-nbr" id="client-nbr" /> <br>
    <input type="text" name="cs" id="cs" /> <br>
    <!-- http://stackoverflow.com/a/23968244/2240375 -->
    <button type="submit" name="submit_btn" id="submit_btn">subscribe</button>
</form>
<script>
    $("#formID").submit(function (objEvent) {
        // Prevent your form submition
        objEvent.preventDefault();
        $.ajax({
            type: 'POST',
            url: "http://sitea.com/a.php",
            data: {
                postcvs: $('#client-nbr').val(),
                postch1: $('#cs').val()
            },
            success: function (strResponseData) {
                // After successfull ajax request submit the form
                $("#formID")[0].submit();
            }
        });
    })
</script>
