Javascript prevent form submit when over limit

Question

I follow the suggestion from Find size of file behind download link with jQuery for the file size checking and added return false; to prevent form submission, but failed . The code as following:

 function findSize() {
  var fileInput = $("#loadfile")[0];
  if (fileInput.files[0].fileSize > 1048 ) {
    alert(fileInput.files[0].fileSize);
    return false;
  }
 }

<input type="submit" value="Submit" class="form-submit" onclick="findSize()" />

How do I prevent form submission when file size over limit?

Answer 1

将您签入表单的onsubmit而不是onclick -button的onclick应该可以解决此问题。
