Php 结合sql查询和javascript的结果来计算字段

php javascript jquery sql

Php 结合sql查询和javascript的结果来计算字段,php,javascript,jquery,sql,Php,Javascript,Jquery,Sql,我对JavaScript非常陌生， javascript中的数组有问题。直截了当地说：我有HTML代码： <input type="text" name="conPrice" id="conPrice" size="16" maxlength="128"/> <input type="text" name="OverP" id="OverP" size="16" maxlength="128" /> <div id="slider"></div&g

我对JavaScript非常陌生， javascript中的数组有问题。直截了当地说：我有HTML代码：

<input type="text" name="conPrice" id="conPrice" size="16" maxlength="128"/>
<input type="text" name="OverP" id="OverP" size="16" maxlength="128"  />
<div id="slider"></div> //Slider

我试图根据我的滑块值在字段OverP中获取价格列price。例如，如果滑块上有数字6，最小值和最大值介于1-7之间，那么价格应该是10

我有一个SQL：

<?php
$x = mysql_query("SELECT p_max AS max FROM dsd_price");
$y = mysql_query("SELECT p_min AS min FROM dsd_price");
$z = mysql_query("SELECT p_price AS price FROM dsd_price");
while ($x_array = mysql_fetch_array($x)){$max[] = $x_array;}
while ($y_array = mysql_fetch_array($y)){$min[] = $y_array;}
while ($z_array = mysql_fetch_array($z)){$price[] = $z_array;}
?>

您的方括号似乎与calcul（）函数不匹配。试试这个：

$(document).ready(function calcul() {
var frm = document.dsd_form;
var quant = frm.conPrice;
var overp = ['<?php echo implode("','", $price); ?>'];
var mini = ['<?php echo implode("','", $min); ?>'];
var maxi = ['<?php echo implode("','", $max); ?>'];
for(index = 0; quant > mini[index], quant < maxi[index]; index++)
{
    $( "#OverP" ).val( overp[index] );
}});

$（文档）.ready（函数calcul（）{
var frm=document.dsd\u表单；
var quant=frm.conPrice；
var overp=['到目前为止，我没有得到任何结果，因为JS的最后一部分肯定有错误。如果我要取出以$（document）.ready开头的部分（函数calcul（）{它将使用Firebug（Firefox）或Chrome的开发工具（F12打开它）等浏览器工具向conPriceTry提供滑块和数字输出。它会显示任何JS错误。我运气不好，试图在FireFox中查找错误，但没有显示任何可能与topicTry Chrome的开发工具相关的错误。如果没有出现红色的弹出窗口，那么您至少没有JS语法错误。而且，您的Javascript看起来像jquery。这正确吗？是的，我正在呼吁，所以这不应该是一个错误问题
