Turn off autocomplete

If this is nothing related to by default behavior of different browsers then you have the option "Autocomplete" selected for "text-entry" question which you can change by selecting any other option which available.
Below is the support page:

Indeed, it's related to by default behavior of the browser. I want to block the browser to autocomplete or autofill a questions like name, city,...
I trided to add a Javascript like :
Qualtrics.SurveyEngine.addOnReady(function()
{
autocomplete="off"
});
But it didn't work..

Hi there, if you still need, I was able to put this in place by following the recommendation mentioned in this stackoverflow thread. The top answer recommends trying to confuse the browser by naming input ids in a way that the browser won't attempt to autofill or by setting the autocomplete attribute to a value that the browser won't recognize as an autofillable field. I went with the 2nd option, setting autofill to "do-not-autofill" instead of "off" or "no". Try adding the below to the OnReady section of the Form Field question's JavaScript:
jQuery("#"+this.questionId+" input[type='text']").each(function() {
            jQuery(this).attr("autocomplete", "do-not-autofill");
          });
Adapted from here.
