使用jquery定期自动提交表单

Question

我想在特定的时间段内使用jquery递归提交表单是否有办法这样做？

Answer 1

您可以使用setInterval执行此操作，例如：

<script>
window.setInterval(sendForm, 3000);  // 3000 millisecons, or 3 sec

function sendForm() {
    //get the action-url of the form
    var actionurl = document.getElementById("theForm").action;

    //do your request an handle the results
    $.ajax({
            url: actionurl,
            type: 'post',
            dataType: 'json',
            data: $("#theform").serialize(),
            success: function(data) {
                // You don't really want a window alert here, since
                // it will block the execution. Only used for demo
                // here you'd run the code after your form submits
                // succesfully
                window.alert("Submitted form");
            }
    });

}

</script>
<form id="theForm" method="POST" action="myReceiver.php">
  <input type="text" value="demo value">
</form>

您可以使用setTimeout javascript函数实现此目的。
