Finally I think I came with a decent solution. Understanding better how the dropdown works with Chrome helped :) Basically, the dropdown will be displayed when you focus the input and when you generate a mouse down event when you are typing an entry which matches with what Chrome has in memory. Keeping that in mind, and that Chrome does it for certain inputs when they have default names like "name", "email", etc. then we just need to remove the name when the dropdown is going to be displayed and add it back after :) I wanted to use a solution which can make it work just by adding the attribute autocomplete off. I thought it made sense. This is the code:
Solution 1
jQuery('body').on('mousedown','[name="name"][autocomplete="off"], [name="email"][autocomplete="off"]',function(e){
e.stopImmediatePropagation();
if(typeof this.currentName =="undefined")
this.currentName=jQuery(this).attr('name');
jQuery(this).attr('name','');
});
jQuery('body').on('blur','[autocomplete="off"]',function(e){
e.stopImmediatePropagation();
jQuery(this).attr('name',this.currentName);
});
Solution 2 (My Favourite One)
The solution I described above will remove the name of the input until we remove the focus (blur), in that moment it will put the original name back. But might happen that we are interested on having access to the input through its name attribute while we are typing. Which means that we need to put the name back right after each input. This solution, basically is based on the first solution. In this case, we will add the name on key down, and put it back on keyup. I think this is more neat for compatibility with what the "autocomplete off" behaviour should be. Anyway this is the code:
jQuery('body').on('mousedown keydown','[name="name"][autocomplete="off"], [name="email"][autocomplete="off"]',function(e){
e.stopImmediatePropagation();
if(typeof this.currentName =="undefined")
this.currentName=jQuery(this).attr('name');
jQuery(this).attr('name','');
});
jQuery('body').on('blur keyup','[autocomplete="off"]',function(e){
e.stopImmediatePropagation();
if(typeof this.currentName !="undefined")
jQuery(this).attr('name',this.currentName);
});
Please notice that for Solution 1 and 2, I just took the cases where the input name is "name" and "email". For any other case where this attribute makes Chrome generate the dropdown you will have to add it in the selector for the mouse down event.
Solution 3
This solution is a lot more messy. I did not realize that the behaviour we are trying to correct is just based on those inputs with a specific name like "name, email, etc". The approach of this solution was for that case that Chrome display for other names that we don't know a priori. It would be a very generic solution. I do not like as much as the other 2, basically because there could be a small flicker when we press on the delete key. I will explain that bellow.
I found out that the dropdown was appearing after a second click on the input but not on the first click when you focus the first time on the input. I bind a "mousedown" event for all this elements where the handler basically detect if it is already focused on the input and in case it detects another "mouse down", force a .blur() and then .focus() after, preventing the dropdown on the second click once it is focused. I hope, it is clear, just in case here is the code that I used:
jQuery('body').on('mousedown','[autocomplete="off"]',function(e){
e.stopImmediatePropagation();
if(jQuery(this).is(':focus')) {
jQuery(this).blur();
jQuery(this).focus();
}
});
In the other hand, in order to prevent the dropdown while you are typing in case it matches with Chrome suggestions... This is a little bit tricky. I just decided to replace the default behaviour of an input while user types. The dropdown evaluates the input on mouse down, so I prevent the default behaviour for alphanumerics, space, etc. The only problem is with Command,Ctrl and delete. For this case I had to bind also an event on mouse up. It allows the default behaviour in the first two cases so you can make copy, and paste, or select all. In the case of the delete, I have to allow the default behaviour, but if after deleting a character the input matches with Chrome suggestions, then again it was showing the dropdown. For this case I had to use the same trick of blur and focus. The only inconvenience I found on this is that since we are cancelling the behaviour on keyup, and chrome tries to show it on keydown, there is a small flicker. Anyway, this is the best I could do. Probably it will require for filtering of characters at one point. I just added the conditions made more sense for now. This is the second part of the code:
jQuery('body').on('keydown','[autocomplete="off"]',function(e){
e.stopImmediatePropagation();
var ctrlKey = 17,cmKey = 91;
var charCode = e.which || e.keyCode;
if(charCode!=16 && this.commandDown != true && this.ctrlDown != true && ((charCode>47 && charCode<58)||(charCode>64 && charCode<91)||(charCode>96 && charCode<123)||charCode==0 || charCode==32)){
e.preventDefault();
var charStr = String.fromCharCode(charCode);
if(!e.shiftKey)
charStr = charStr.toLowerCase(charStr);
$(this).val($(this).val() + charStr);
}else{
if (charCode == cmKey) this.commandDown = true;
if (charCode == ctrlKey) this.ctrlDown = true;
}
});
jQuery('body').on('keyup','[autocomplete="off"]',function(e){
e.stopImmediatePropagation();
var allowed=[8];//Delete
var ctrlKey = 17,cmKey = 91;
var charCode = e.which || e.keyCode;
if (charCode == cmKey) {this.commandDown = false};
if (charCode == ctrlKey) {this.ctrlDown = false};
if(allowed.indexOf(charCode)>=0 || (this.commandDown!=false && this.ctrlDown!=false)){
jQuery(this).blur();
jQuery(this).focus();
}
As I said this solution is much more messy. It was the first one I used until I realized that the dropdown just appeared for certain input names.
Sorry for writing so much, I just wanted to be sure everything was clear. I hope it helps.
