如何将php数组值分配给javascript数组

Please provide help on how to assign php array values to javascript array

请提供有关如何将php数组值分配给javascript数组的帮助

----------- Using below php code I am storing data in php array -----------

-----------使用下面的php代码我在php数组中存储数据-----------

<?php
$str_query="SELECT title,description FROM tablename ORDER BY title";
$rs_sch=GetRecordset($str_query); 

$int_count=0;
$schd_arr = array();
while(!$rs_sch->EOF())
{
$schd_arr[$int_count] = $rs_sch->Fields("title").": ".$rs_sch->Fields("description");
$rs_sch->MoveNext();
$int_count++;
}
?>

----- Using below javascript code I am trying to store php array data into javascript array -----

-----使用下面的javascript代码我试图将php数组数据存储到javascript数组-----

Please let me know what and how to write variable at below 2 mentioned locations so my code can work.

请让我知道在以下2个位置写入变量的内容和方式,以便我的代码可以正常工作。

<script type="text/javascript" language="javascript">
var pausecontent=new Array()
for (sch_cnt=0; sch_cnt<*Here I want to assign value of $int_count php variable*; sch_cnt++)
{
pausecontent[sch_cnt]=<?php *Here I want to assign php array and counter values (something like this - $schd_arr[sch_cnt];)* ?>;
}
</script>

Thank you in advance, KRA

先谢谢你,KRA

You can't loop like that, you need to loop the PHP array and push into javascript array:

你不能这样循环,你需要循环PHP数组并推入javascript数组:

<script type="text/javascript" language="javascript">
    var pausecontent = new Array();
    <?php foreach($schd_arr as $key => $val){ ?>
        pausecontent.push('<?php echo $val; ?>');
    <?php } ?>
</script>

#2

You can directly use the json_encode function. It is easy to use and produces valid javascript so is very stable:

您可以直接使用json_encode函数。它易于使用并生成有效的JavaScript,因此非常稳定:

<script type="text/javascript">
    var pausecontent = <?php echo json_encode($php_array); ?>;
</script>

#3

I think you'd best get the array to your javascript first. That would be something like this:

我认为你最好先把数组放到你的javascript中。这将是这样的:

var theVariableYouWantTheArrayIn = <?php echo json_encode($theArrayYouWantInJavascript); ?>

After that it is a normal js array, so you can use properties like .length which will presumably make the loop much easier.

之后它是一个普通的js数组,所以你可以使用像.length这样的属性,这可能会使循环变得更容易。

Above both answers in good.

以上两个答案都很好。

Iterate through the array you got as a result of your DB query and add each value to a new PHP variable,

迭代通过数据库查询得到的数组,并将每个值添加到新的PHP变量中,

Add a counter and increment it during each iteration to make sure that you’re not adding a comma after the last element,

添加一个计数器并在每次迭代期间递增它,以确保在最后一个元素之后不添加逗号,

If the count of the elements in the array is more than 1, create the array as usual, otherwise create a new array with 1 element and assign your PHP array value to the index 0.

如果数组中元素的数量大于1,则照常创建数组,否则创建一个包含1个元素的新数组,并将PHP数组值分配给索引0。

I had the same problem doing this but finally found the best solution

我这样做有同样的问题,但最终找到了最佳解决方案

    <script>       
    var arr=[];
    arr.push('<?php
             include('conn.php');
        $query = "SELECT *FROM c group by name";
        $res = mysqli_query($conn,$query) or die(mysqli_error($conn));

        while($data = mysqli_fetch_array($res))
        {


             echo $data["name"];
        }
             ?>');
        </script>

You can just do like this with both:

你可以这样做:

for (sch_cnt=0; sch_cnt<?php echo $int_count; ?>; sch_cnt++)
