如何在没有循环的情况下通过索引访问mAdView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
// Code to be executed when an ad finishes loading.
}
@Override
public void onAdFailedToLoad(int errorCode) {
// Code to be executed when an ad request fails.
}
@Override
public void onAdOpened() {
// Code to be executed when an ad opens an overlay that
// covers the screen.
}
@Override
public void onAdLeftApplication() {
// Code to be executed when the user has left the app.
}
@Override
public void onAdClosed() {
// Code to be executed when when the user is about to return
// to the app after tapping on an ad.
}
});
？我有以下代码
RecursiveArrayIterator我只想通过电子邮件发送密钥，如果我提供选项的密钥而不是值，则ChosenJS将无法正常工作
我可以执行另一个循环来发送密钥，这是我目前正在暂时执行的但是错误的，$json = file_get_contents("careers.json");
$jsonIterator = new RecursiveIteratorIterator(
new RecursiveArrayIterator(json_decode($json, TRUE)),
RecursiveIteratorIterator::SELF_FIRST);
<select class="form-control position" name="position" required>
<?php $option = 0;
foreach($jsonIterator as $key => $val){
if(is_array($val)){ $option++; ?>
<option value="<?= $option; ?>"><?= $key; ?></option>
<?php }}?>
</select>
建议在聊天存储Peehaa并访问它。
有许多可能的解决方案，但我有兴趣以这种方式访问它以用于教育目的
json_decodeJson示例，它是一个包含许多段落的文件，这是一个示例结构：
$index = $_POST['position'];
$key= $jsonIterator[$index];
