When we submit a form , browser will add autocomplete with input (if enabled)
But ajax post won't effect
This is a solution:
1. Add a hide iframe with empty page
<iframe name="hiddenIframe" class="hide" src="javascript:false"></iframe>
2. Let your form target with the iframe
<form target="hiddenIframe" id="myForm">
<input name="some_input" />
<button onclick="ajaxPost(this);">btn</button>
</form>
3. Trigger a submit event on this form when you send a AJAX post for it
<script>
function ajaxPost(obj){
$("#myForm").submit();
//do your ajax post
}
</script>
OK, now the input can catch user insert string for browser auto suggetst(autocomplete)
