此代码工作正常，但我的问题是....当我从选择框中选择一个选项时 id =“ser”我在 onchange =“getPrice中调用一个函数（ this.value）;“其工作完美ajax结果显示在指定字段中有时1或3分钟有时超过5分钟如何减少浪费时间
请帮忙......

Answer 1

使用LEFT join使用一个SQL，而不是使用两个SQL来获取数据，这样可以节省一些时间。

<?php
    $querydep=$db->execute("select pp.mrp, pp.sale_price, pa.product_type
    from productsale_price As pp LEFT JOIN product_add As pa 
       ON pa.product_code = pp.product_code AND pa.delet='0' 
        where pp.product_code='$cod'");
    $pprce=$querydep->fetch_assoc();
    $_SESSION['prdtype']=$pprce['product_type'];
    $_SESSION['mrp']=$pprce['mrp'];
    echo $pprce['sale_price'];
?>

您是否为表productsale_price，product_add和master_purchase创建了索引？

如果没有，您需要索引： - product_code上的productsale_price - product_add on productcode and - master_purchase product_code

这应该可以做到！当然，我假设您的SQL服务器在最佳条件下运行，并且不是导致响应缓慢的原因！

Ajax响应时间太长
