Question

我在桌子上有这样的数据：

pray_name | time_before_iqamah
Subuh     | 1
Dhuhur    | 10
Ashar     | 10
Maghrib   | 10
Isya      | 10

我将它生成到PHP jSon

$qPray = mysqli_query($con, "SELECT * FROM tb_prays WHERE active = 'Y'");
while($dPray = mysqli_fetch_array($qPray))
{
    $timeBeforeIqamah[] = $dPray['time_before_iqamah'];
}

jSon结果

{"timeBeforeIqamah":["1","10","10","10","10"]}

现在我希望根据JS上的祈祷名称获得timeBeforeIqamah。

var list = ["Imsak", "Subuh", "Terbit", "Dhuhur", "Ashar", "Maghrib", "Isya"];
var times = prayTimes.getTimes(date, geo, timezone);

for(var i in list)
{
    if(jsonStr.currentTime == times[list[i].toLowerCase()] + ":00")
    {
        if(list[i] == "Imsak" || list[i] == "Terbit")
        {}
        else
        {
            alert(jsonStr.timeBeforeIqamah[i]);
        }
    }
}

假设我们处于Subuh时间意味着我尝试alert(jsonStr.timeBeforeIqamah[i]);应该获得价值：1，但我得到的是：10 < / p>

我想要的是基于JS上的祈祷名称得到time_before_iqamah。

怎么做？

Answer 1

问题是您的表格中的数据与list中的数据的顺序不同：

Index | pray_name | time_before_iqamah
0     | Subuh     | 1
1     | Dhuhur    | 10
2     | Ashar     | 10
3     | Maghrib   | 10
4     | Isya      | 10

将其与：

进行比较

var list = ["Imsak", "Subuh", "Terbit", "Dhuhur", "Ashar", "Maghrib", "Isya"];

Index | Value
0     | "Imsak"
1     | "Subuh"
2     | "Terbit"
3     | "Dhuhur"
4     | "Ashar"
5     | "Maghrib"
6     | "Isya"

在第一种情况下，subuh的索引为0，在第二种情况下，它的索引为1，因此无法与之匹配。

要解决此问题，您可以更改您的php，以便传递与值匹配的名称：

$qPray = mysqli_query($con, "SELECT * FROM tb_prays WHERE active = 'Y'");
while($dPray = mysqli_fetch_array($qPray))
{
    $timeBeforeIqamah[$dPray['pray_name']] = $dPray['time_before_iqamah'];
}

然后将您的javascript更改为：

 if(list[i] == "Imsak" || list[i] == "Terbit")
 {}
 else
 {
      alert(jsonStr.timeBeforeIqamah[list[i]]);
 }

Javascript根据pray_name
