我不确定这是否可行，但这是我无法弄清楚的问题.

I am not really sure if this is possible but here is the problem I cant figure out.

在这个链接中有一个结果.

Have a from that results in the this link.

最终结果链接.

http://www.website.com/index.php?a=price_range_A_B

我不能使用 from 但我可以使用输入字段.有什么想法吗?

I can not use a from but i can use Input fields. Any ideas?

EDIT : 由于 OP 更改了问题，我在下面更新了我的答案.

EDIT : Since the OP changed the question I have updated my answer below.

我举了一个例子来说明如何做到这一点.

I am putting an example of how you could do this.

<?php  
    $action_path = "index.php";
    ?>

    <script type="text/javascript">
        function submitData() {
            var a = null;
            var _A = document.getElementById("_A").value;
            var _B = document.getElementById("_B").value;

            a = "price_range_" + _A + "_" + _B;

            window.location.href = "<?php echo $action_path; ?>?a=" + a;

            return;
        }
    </script>

    <input type="text" id="_A" maxlength="6" size="5" />
    <input type="text" id="_B" maxlength="6" size="5" />
    <input type="button" value="Submit" onclick="submitData();" />

    <?php
    // the code to be put after </form> goes here
?>
