Javascript Submit() Is Not Submitting The Form

This is my code. HTML

use the onsubmit to disable the button instead of using weird inline handlers. There is no href on a button for example

You should not disable a button you need to click before clicking it

Like this:

<formid="add_new_video"method="post"class="appnitro"style="margin-left:70px;"action="<?phpecho base_url()?>videos/save"><inputtype="text"name="name"><buttontype="submit"id="buttonSub"class="dark_text_link">Add New Video</button></form>

using

window.onload=function() {
  document.getElementById("add_new_video").onsubmit=function() {
    document.getElementById('buttonSub').disabled = true;
    setTimeout(function(){document.getElementById('buttonSub').disabled = false;},1000);
  }        
}

You do not actually need to ENABLE the form button again since you submit to the same page. The button will be enabled when the page reloads - this is of course not true if you target the form elsewhere

Solution 2:

Replace button with this tag element.

<inputtype="submit"class="dark_text_link" disabled id="btnsubmit" href="javascript:void(0);" onclick="return addVideo();"/>
