大家好我是新手我有一个关于如何将输入形式变为请求URL的问题

      <!DOCTYPE HTML>
      <html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

        <script type="text/javascript">

        $(document).ready(function() {
            var options = {
                chart: {
                    renderTo: 'container',
                    plotBackgroundColor: null,
                    plotBorderWidth: null,
                    plotShadow: false,
                },
                title: {
                    text: '中国武夷 000797 历史大单 from 2016-03-14'
                },
                tooltip: {
                    formatter: function() {
                        return '<b>'+ this.point.name +'</b>: '+ Highcharts.numberFormat(this.percentage,2) +' %';
                    }
                },
                plotOptions: {
                    pie: {
                        allowPointSelect: true,
                        cursor: 'pointer',

                            formatter: function() {
                               return '<b>'+ this.point.name +'</b>: '+ Highcharts.numberFormat(this.percentage,0) +' %';
                            }
                        }
                    }
                },
                series: [{

             $jsonurl="000797vol400piedata.php?df=";
             $.getJSON($jsonurl, function(json) {
                 options.series[0].data = json;
                 chart = new Highcharts.Chart(options);
             });

     $('#button').click(function() {
        $jsonurl="000797vol400piedata.php?df=";
        $.getJSON($jsonurl2, function(json) {
                    options.series[0].data = json;
            chart = new Highcharts.Chart(options).redraw();                   
            });
         });

            // window.setInterval(function(){
            //  $.getJSON("000797datapievol400.php", function(json) {

000797vol400piedata.php代码是

<?php
$con = mysql_connect("localhost","tushare","tusharetushare");
$df = htmlspecialchars($_GET["df"]) ;
if (!$con) {
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("stockhistory", $con);

$resultx = mysql_query("select type,sum(volume) from `vol400-000797` where type='买盘' and date BETWEEN '$df' AND current_date()");
$rowsx = array();
while($r = mysql_fetch_array($resultx)) {
    $row[0] = $r[0];
    $row[1] = $r[1];
    array_push($rowsx,$row);
}

$resulty = mysql_query("select type,sum(volume) from `vol400-000797` where type='卖盘' and date BETWEEN '$df' AND current_date()");
$rowsy = array();
while($r = mysql_fetch_array($resulty)) {
    $row[0] = $r[0];
    $row[1] = $r[1];
    array_push($rowsy,$row);
}

$resultz = mysql_query("select type,sum(volume) from `vol400-000797` where type='中性盘' and date BETWEEN '$df' AND current_date()");
$rowsz = array();
while($r = mysql_fetch_array($resultz)) {
    $row[0] = $r[0];
    $row[1] = $r[1];
    array_push($rowsz,$row);
}


$rows=array_merge($rowsx,$rowsy,$rowsz);


print json_encode($rows, JSON_NUMERIC_CHECK);

mysql_close($con);
?>

我认为表单代码有问题单击按钮
时，$ jsonurl2无法获取值

Answer 1

您的表单操作必须是000797vol400piedata.php，因此您的表单应如下所示：

.css()

并在000797vol400piedata.php

使用$ _GET ['df']得到df值：

<form name="form" action="000797vol400piedata.php" method="GET">
        <input type="text" name="df" id="df" value="2016-4-1" />
        <input type="submit" name="submit" value="Start Date" />
</form>

在你的情况下，为了在javascript中使用PHP变量，你应该考虑使用ajax。所以你的代码必须是：

$df = $_GET['df'];

停止使用mysql扩展，使用PDO或mysqli。

Answer 2

请查看代码的这一行

<form name="form" action="<?php $jsonurl2 = $jsonurl.$_GET['df'];?>" method="GET">

在表单的action属性中

action="<?php $jsonurl2 = $jsonurl.$_GET['df'];?>"

替换为

action="000797vol400piedata.php"

也在表格内，在这一行

<input type="button" id="button" value="Start Date" />

在

中更改

<input type="submit" id="button" value="Start Date" />

并且您的表单必须如下所示

  <form name="form" action="000797vol400piedata.php" method="GET">
    <input type="text" name="df" value="2016-4-1" />
    <input type="submit" id="button" value="Start Date" />
  </form>

在你的000797vol400piedata.php中，你可以这样做，以获得你传递的var的值。这只是如何接收表单发送的值的示例。以此为例进行编码。

$value = $_GET['df'];
echo "$df";

mysql highcharts pie php将var值转换为请求url
