Question

我已经设置了一个AJAX实时搜索，我想知道何时从数据库中提取信息是否可以将其放入不同的结果div中？

因为我想单独设计它们。我甚至希望一次出现一个，但我想首先解决这个问题。

我现在设置它的方式可以工作，但是element.style正在改变我的愿景:(

当我搜索时再说一遍，当它返回结果时，可以进入不同的结果div？

如果您搜索空气，它将返回三个结果。

忘记添加JavaScript;

Answer 1

我给你一个“想法/示例”如何在我阅读你的评论之后让你的代码正常工作：

PHP文件：

...

if (isset($result_array)) {

    foreach ($result_array as $result) {

        $isResult = true; // We set a variable for checking if we have a result or not

        $arrayFetch[] = [ 

           // Passing your result
           'output_1' => $result['foo_1'],
           'output_2' => $result['bar_1']
        ];
    }

} else {

    $isResult = false;

    $arrayFetch[] = [

        'output_3' => $result['foo_2'],
        'output_4' => $result['bar_2']
    ];
}

// We encoding to json
echo json_encode([

    'isResult' => $isResult,
    'result'   => $arrayFetch 
]);

...

Javascript（jQuery）文件：

// Create a function to decode your result (I do it only for a cleaner code)
function getResult(data) {

    // Initialize your variable result
    var a = '',
        b = '';

    // Here we check if our $isResult are true or false
    if (true === data.isResult) {

        // Here came the .each() function in play
        $.each(data.result, function(i, obj) {                

            a = '<li>' + obj.output_1 + '</li>' +
                '<li>' + obj.output_2 + '</li>';                   
        });

    } else {

        b = '<li>' + obj.output_3 + '</li>' +
            '<li>' + obj.output_4 + '</li>';
    }

    // Return your result
    return a + b;
}

$(document).ready(function() {

    // I pick up your search function
    function search() {

        var query_value = $('input#search').val();

        // Ajax call
        $.ajax({
            type: 'POST',
            cache: false,
            dataType: 'json', // <== Notice the datatype:
                              // For transporting JSON-formatted data,
                              // which can include strings, arrays, and objects
            data: { query: query_value },
            beforeSend: function() { /* some loader */ }

        }).done(function(json) {

            // Putting result from function getResult() into your HTML 
            $('ul#results').html(getResult(json));

        }).fail(function() { /* some error handling */ });

        return false;
    }

    // Thats your original code, except that I change the .live() to .on() 
    $("input#search").on("keyup", function(e) {
        // Set Timeout
        clearTimeout($.data(this, 'timer'));

        // Set Search String
        var search_string = $(this).val();

        // Do Search
        if (search_string == '') {

            $("ul#results").fadeOut();
            $('h4#results-text').fadeOut();

        }else{

            $("ul#results").fadeIn();
            $('h4#results-text').fadeIn();
            $(this).data('timer', setTimeout(search, 100));
        };
    });
});

请记住，这只是一个例子！
