需要知道如何传递username、caption、formIng等信息来从handleFormSubmit添加Post

function handleFormSubmit(event) {
   // This next line prevents the reload of the form
   event.preventDefault();
   // Get values of inputs
   // Pass values to addNewPost()
   var username = document.getElementById("formUsername").value;
   var caption = document.getElementById("formCaption").value;
   var formImg = document.getElementById("formImg").value;

function addNewPost(username, caption, imgLocation) {




}

Answer 1

您可以在handleFormSubmit 函数中调用addNewPost 函数并传递值。

function handleFormSubmit(event) {
   // This next line prevents the reload of the form
   event.preventDefault();
   // Get values of inputs
   // Pass values to addNewPost()
   var username = document.getElementById("formUsername").value;
   var caption = document.getElementById("formCaption").value;
   var formImg = document.getElementById("formImg").value;

   addNewPost(username, caption, formImg ); // call the function here.
}
function addNewPost(username, caption, imgLocation) {


}
