set value to jquery autocomplete combobox

Question

I am using jquery autocomplete combobox and everything is ok. But I also want to set specific value through JavaScript like $(\"#value\").val(\"somevalue\") and

Answer 1

I managed a quick and dirty way of setting the value. But, you do need to know both the value and the text of the item that you want to display on the dropdown.

var myValue = foo; // value that you want selected
var myText = bar; // text that you want to display
// You first need to set the value of the (hidden) select list
$('#myCombo').val(myValue);
// ...then you need to set the display text of the actual autocomplete box.
$('#myCombo').siblings('.ui-combobox').find('.ui-autocomplete-input').val(myText);

http://jsfiddle.net/nhJDd/

$(".document").ready(function(){
    $("select option:eq(1)").val("someNewVal");
    $("select option:eq(1)").text("Another Val");
    $("select option:eq(1)").attr('selected', 'selected');

});

here is a working example and jquery, I am assuming you want to change the value of a select, change its text face and also have it selected at page load?

Attempt 2:

here is another fiddle: http://jsfiddle.net/HafLW/1/ , do you mean that you select an option, then you want to append that value to the autocomplete of a input area?

$(".document").ready(function(){
     someString = "this,that";
        $("input").autocomplete({source: someString.split(",")}); 

    $("select").change(function(){
        alert($(this).val()+" appended");
someString = someString+","+$(this).val();
        $("input").autocomplete({source: someString.split(",")}); 


    });
});

I really like what andyb did, but I needed it to do a little more around event handling to be able to handle triggering the a change event because "selected" doesn't handle when hitting enter or losing focus on the input (hitting tab or mouse click).

As such, using what andyb did as a base as well as the latest version of the jQuery Autocomplete script, I created the following solution: DEMO

• Enter: Chooses the first item if menu is visible
• Focus Lost: Partial match triggers not found message and clears entry (jQuery UI), but fully typed answer "selects" that value (not case sensative)

How Change method can be utlized:

$("#combobox").combobox({
    selected: function (event, ui) {
        $("#output").text("Selected Event >>> " + $("#combobox").val());
    }
})
.change(function (e) {
    $("#output").text("Change Event >>> " + $("#combobox").val());
});

Hopefully this helps others who need additional change event functionality to compensate for gaps that "selected" leaves open.

Answer 4

Is this demo what you are looking for?

The link sets the value of the jQuery UI autocomplete to Java. The focus is left on the input so that the normal keyboard events can be used to navigate the options.

Edit: How about adding another function to the combobox like this:

autocomplete : function(value) {
    this.element.val(value);
    this.input.val(value);
}

and calling it with the value you want to set:

$('#combobox').combobox('autocomplete', 'Java'); 

Updated demo

I cannot find any available existing function to do what you want, but this seems to work nicely for me. Hope it is closer to the behaviour you require.

@andyb, i think rewrite:

    autocomplete: function (value) {
        this.element.val(value);

        var selected = this.element.children(":selected"),
                value = selected.val() ? selected.text() : "";
        this.input.val(value);
    }
