在rails上的ruby中提交“submit”之前执行js代码

Question

i can't seem to make the old js scripts that i found on the magical SO.

<div class="form-actions">
    <%= f.button :submit, class:"btn btn-success create-campaign" %>

  </div>

this is my submit button.But there is a problem.

<div class="message-div" id="textField" contenteditable="true" maxlength="180"></div> 
<%= f.input :message ,as: :text,as: :hidden  ,input_html: { class: 'special', maxlength:'180' } %>

i use div to get the input for what i have done for it but my form takes its input from the hidden text area.

So i tried to do take take the content of the div and write it to the text area when submit button clicked.

but the js script that i wrote does not getting executed.

$(document).on("click",".create-campaign",function(e){

console.log('asdasd');

var a = $('.message-div').html();


document.getElementById('.special').value = a;

});

this is the code.

When i changed the listener class to another button, it works without a problem ( at least i see console log) but not when the submit button is pressed.

What should i do?

Cheers.

You need to prevent the default submit action from being triggered:

$(".create-campaign").click(function(e) {
  e.preventDefault();
  console.info('asdasd');
  var a = $('.message-div').html();
  alert(a); // just to check that your data is there
  document.getElementById('.special').value = a;
  $("#YOUR_FORM_ID").submit();
});
