如何让input元素触发jQuery自动完成小部件？

Question

我有几个使用jQuery自动完成功能增强的输入字段.触发选择事件时如何获取相应的输入字段？

<input name="1" value="">
<input name="2" value="">
<input name="3" value="">

$('input[type=text]').autocomplete({
    source: 'suggestions.php',
    select: function(event, ui) {
        // here I need the input element that have triggered the event
    }
});

Answer 1

我正在为sourceparam 使用匿名函数,并$(this)在其中引用了函数,而不是触发它的元素.我不得不使用$(this.element).

最终的代码与此类似(我将其简化为演示目的):

$( ".regionsAutocomplete" ).autocomplete({
    source: function(request, response){

        //The next line is the important one for this example
        var input = this.element;
        $(input).css('color','red');

        var data = {'foo':'bar'};
        $.ajax({
            'url': ajaxurl,
            'data': data,
            'method': "POST",
            'dataType': "json",
            'success': function(data) {
                response(data);
            }
        });
    }
});

Answer 2

尝试使用 $(this)

$('input[type=text]').autocomplete({
    source: 'suggestions.php',
    select: function(event, ui) {
        // here I need the input element that have triggered the event
        alert($(this).attr('name'));
    }
});
