城市数据json ($ cityJsonObject )
Array ( [0] => stdClass Object ( [cityId] => c1 [cityName] => Kajang [cityStateId]
=> s2 ) [1] => stdClass Object ( [cityId] => c2 [cityName] => Seputeh
[cityStateId] => s1 ) [2] => stdClass Object ( [cityId] => c3 [cityName] => Shah
Alam [cityStateId] => s2 ) [3] => stdClass Object ( [cityId] => c4 [cityName] =>
Klang [cityStateId] => s2 ) [4] => stdClass Object ( [cityId] => c5 [cityName] =>
Kepong [cityStateId] => s1 ))
代码(cityName)
<?php
for($i = 0; $i < count($cityJsonObject); $i++)
{
echo $cityJsonObject[$i]->cityName;
//PASS VARIABLE TO JS
}
?>
<script type="text/javascript">
//GET VARIABLE FROM PHP AND DISPLAY CITY NAME
</script>
从上面的代码中,我可以得到以下内容:
Kajang
Seputeh
Shah Alam
Klang
Kepong
我的问题是如何将上述城市名称传递给变量并传递给js?我应该怎么做?
答案 0 :(得分:1)
您可以使用json_encode
并输出一个字符串,该字符串将通过javascript轻松解析
试试此代码
<?php
$array_to_js = array();
for($i = 0; $i < count($cityJsonObject); $i++)
{
$array_to_js[] = $cityJsonObject[$i]->cityName;
}
?>
<script type="text/javascript">
//GET VARIABLE FROM PHP AND DISPLAY CITY NAME
var js_array = <?php echo json_encode($array_to_js, JSON_HEX_QUOT) ?>;
</script>

<?php
echo '<script type="text/javascript">';
// your php code here maybe you can need json_encode(), I'm not sure I get what you mean.
echo json_encode($cityJsonObject);
echo '<script>';
?>
