Question

我已将我的网站设置为使用gitter弹出系统。 javascript看起来像这样：

$(document).ready(function(){
    setTimeout(function() {
        $.gritter.add({
            title: 'Welcome!',
            text: 'This appears to be your first time playing. Blablabla',
            time: '25000'
        }); 
    }, 500);                        
    setTimeout(function() {
        $.gritter.add({
            title: 'Walkthrough',
            text: 'A walkthrough was setup ...',
            time: ''
        }); 
    }, 30000);          
    setTimeout(function() {                         
        $.gritter.add({
            title: 'You got mail',
            text: 'You have received a message from x ',
            time: ''
        }); 
    }, 36000);

这是3个弹出窗口的示例。我想要做的是有这样的数组：

    $popup_title[0] = "Welcome!"; 
    $popup_text[0] = "This appears to be ..."); 
    $popup_time[0] = 25000;

        $popup_title[1] = "Walkthrough"; 
        $popup_text[1] = "A basic blabla ..."); 
        $popup_time[1] = "";

循环遍历此数组（如果它们不是空的）并根据数组构造javascript。

Answer 1

这样的事情应该做的工作

<?php
$popups = array();
foreach ( $popup_title as $key => $title )
{
    $popups[$key] = new stdClass();
    $popups[$key]->title = $title;
}
foreach ( $popup_text as $key => $text )
{
    $popups[$key]->text = $text;
}
foreach ( $popup_time as $key => $time )
{
    $popups[$key]->time = $time;
}
?>
<script type="text/javascript">
$(document).ready(function(){
    <?php foreach ( $popups as $popup ): ?>
    setTimeout(function() {
        $.gritter.add(<?php echo json_encode($popup);?>);
    }
    <?php endforeach; ?>
}
</script>

只需回显PHP创建的JavaScript代码。

Answer 3

使用多个数组有点麻烦，尝试使用嵌套数组，并确保正确地在javascript中转义输出（为清楚起见，我在下面不这样做。）

$popups = array(
    array( 'title' => 'First Title', 'text' => 'First Text', 'time' => 25000 ),
    array( 'title' => 'Second Title', 'text' => 'Second Text', 'time' => 2000 ),
);
echo "<script>";
foreach($popups as $idx=>$popup) {
    echo "setTimeout(function() { $.gritter.add({"
        ."title: '{$popup['title']}',"
        ."text: '{$popup['text']}',"
        ."time: ''"
    ."}); }, {$popup['time']}";    
}
echo "</script>";

在php中从数组构造javascript
