我想在 mysql/php 中使用范围滑块进行查询以获取列表。但我不明白如何将变量从 jQuery 传递到 php 文件。我阅读了这个页面和其他页面，但仍然没有得到结果。这是我要传递的 jQuery 代码，我应该怎么做才能传递变量？

如果您想在每次更改时提交值，您可以尝试我的代码，但如果您这样做，您就有一个坏主意.. 最好有一个按钮告诉您的服务器客户端已完成价格选择。

我只是更新您的代码，希望对您有所帮助。

    <script>
        $(function() {
            var sliderChangeCallback = function(){
               var amount1 = $( "#amount1" ).val(), amount2 = $( "#amount2" ).val()

               $.ajax({
                   url : "your url",
                   data : {
                       "amount1" : amount1,
                       "amount2" : amount1
                   },
                   error : function(){
                       "call back error"
                   }
               })
            };

            $( "#slider-range1" ).slider({
                range: true,
                min: 0,
                max: 500,
                values: [ 75, 300 ],
                slide: function( event, ui ) {
                    $( "#amount1" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
                    sliderChangeCallback();
                }
            });
            $( "#amount1" ).val( "$" + $( "#slider-range1" ).slider( "values", 0 ) +
                " - $" + $( "#slider-range1" ).slider( "values", 1 ) );

            $( "#slider-range2" ).slider({
                range: true,
                min: 0,
                max: 500,
                values: [ 75, 300 ],
                slide: function( event, ui ) {
                    $( "#amount2" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
                    sliderChangeCallback();
                }
            });
            $( "#amount2" ).val( "$" + $( "#slider-range2" ).slider( "values", 0 ) +
                " - $" + $( "#slider-range2" ).slider( "values", 1 ) );

        });
    </script>
