如何使用javascript

Question

我需要在成功动态创建表单提交后调用javascript ajax函数。

或者如何使用java脚本检查表单是否成功提交。

Answer 1

以下是如何检查表单是否已提交以及如何处理回调的示例：

＆＃13;

＆＃13;

var form = document.querySelector('form');
var handleSubmit = function (e) {
  // remove the preventDefault
  // added just to demonstrate the value is true
  // without proceeding with submittion and pg refresh
  e.preventDefault()
  form.setAttribute('data-submitted', true)
  console.log(form.getAttribute('data-submitted'))
  handleAjaxCall()
}
var handleAjaxCall = function () {
  console.log('ajax call here!')
}
form.addEventListener('submit', handleSubmit, false)

＆＃13;

<form data-submitted="0">
 <button type="submit">submit</button>
</form>

＆＃13;
