Jquery UI autocomplete; minLength:0 issue
Solution 1
Check out the search
method documentation:
Triggers a search event, which, when data is available, then will display the suggestions; can be used by a selectbox-like button to open the suggestions when clicked. If no value argument is specified, the current input's value is used. Can be called with an empty string and minLength: 0 to display all items.
var source = ['One', 'Two', 'Three', 'Four'];
var firstVal = source[0];
$("input#autocomplete").autocomplete({
minLength: 0,
source: source,
}).focus(function() {
$(this).autocomplete("search", $(this).val());
});
.ui-menu-item{
background : rgb(215, 215, 215);;
border : 1px solid white;
list-style-type: none;
cursor : pointer;
}
.ui-menu-item:hover{
background : rgb(200, 200, 200);
}
.ui-autocomplete{
padding-left:0;
margin-top : 5px;
}

<input id="autocomplete"/> <input id="submit" type="submit"/>

I understand through experiment why the accepted answer (I up-voted) can be considered slightly incomplete. I've added a little bit of intent to make the UX more combo-box-like:
$('#Carrier').autocomplete(
{
source: '@Url.Action("AutocompleteCarrier", "Client")',
minLength: 0,
select: function (event, data) {
$(this).autocomplete('disable');
}
})
.blur(function(){
$(this).autocomplete('enable');
})
.focus(function () {
$(this).autocomplete('search', '');
});

I had the same problem, and solved it this way. I think the code below makes it much clearer what is the text that is sent to the autocompletion service when the field gets focus. In particular, it is clear why it works when the field already contains something.
$(function() {
$("input#autocomplete").autocomplete({
source: "completion.html",
minLength: 0,
select: function( event, ui ) {}
});
});
$("input#autocomplete").focus(function() {
$(this).autocomplete("search", $(this).val());
});

I had the same problem and I got how to workaround this issue.
The problem is that when an option has been selected the input will be focused, this will run search
without any filter and will show the autocomplete
again.
This problem doesn't happen when you select by keyboard because the input
is already in focus, so the code which is inside focus
will not run again.
So to workaround this issue we have to know when the focus is triggered by any mouse/keyboar event.
jQuery("input#autocomplete").focus(function(e) {
if(!e.isTrigger) {
jQuery(this).autocomplete("search", "");
}
e.stopPropagation();
});
e.isTrigger
is used by jQuery
to identify when event
has been triggered automatically or by user.
Solution 5
This actually works! Tested on IE, FireFox
$("input#autocomplete").autocomplete({
minLength: 0,
source: source,
}).focus(function() {
setTimeout( "if ($('#input#autocomplete').val().length == 0) $('#input#autocomplete').autocomplete(\"search\", \"\"); ",1);
});

I am using a JQuery UI auto-complete. I am specifying the min length. If I specify
minLength:2
I need to type 2 characters before the service fires. If I specifyminLength:1
then I only need to type one character before the source service fires.However, when I specify
minLength:0
I still need to type one character. So whats the point of0
? how is it any different than1
? The expected, and desired, behavior would be for it to fire as soon as the input has focus...?Ideas?
Update: For the most part karim's solution below works, however when clicking on the input the options come up and when one is clicked the source is resubmitted the empty string rather than the new option that was just selected, so the auto-complete options that come up after selecting an option are than same as if the box had been empty.
