我首先要为数据库中的插入发布一些ajax数据,这很好用,但是标准html表单的提交失败了:$(“#foo”)。submit(); 控制台消息无休止地循环: - /
<script type="text/javascript">
// variable to hold request var request;
// bind to the submit event of our form $("#foo").submit(function(event){
// abort any pending request
if (request) {
request.abort();
}
// setup some local variables
var $form = $(this);
// let's select and cache all the fields
var $inputs = $form.find("input, select, button, textarea, text, hidden");
// serialize the data in the form
var serializedData = $form.serialize();
// let's disable the inputs for the duration of the ajax request
$inputs.prop("disabled", true);
// fire off the request to /form.php
request = $.ajax({
url: "/insert_payment_data.php",
type: "post",
data: serializedData
});
// callback handler that will be called on success
request.done(function (response, textStatus, jqXHR){
// log a message to the console
console.log("Hooray, it worked!");
$("#foo").submit();
});
// callback handler that will be called on failure
request.fail(function (jqXHR, textStatus, errorThrown){
// log the error to the console
console.error(
"The following error occured: "+
textStatus, errorThrown
);
});
// callback handler that will be called regardless
// if the request failed or succeeded
request.always(function () {
// reenable the inputs
$inputs.prop("disabled", false);
});
// prevent default posting of form
event.preventDefault(); });
</script>
这让我抓狂: - (
答案 0 :(得分:1)
这是正常的:
$("#foo").submit();
request.done
方法末尾的这一行触发了表单的提交,这可能会触发AJAX请求,这会触发request.done
......等等无限: )
我会做什么(尝试)删除该行,并删除底部的event.preventDefault();
语句,这样您的提交将在您执行AJAX请求后照常运行。< / p>
