在 php 代码 functions.php 中移动检测 Innerhtml

Question

在我的 functions.php wordpress 文件中，我有以下代码：

function mia_on_load_script()
{
    // Not our page, do nothing
    if( !is_page( 'test' ) )
        return;
?>

    <script type="text/javascript">
function change1(){
  document.getElementById('mydiv').innerHTML = '<div id="1" style="margin-left: 0px; padding: 0px; float: left; width: 640px; height: 392px; border: 0px;"><iframe style="border: 0 none transparent;" src="//www.ustream.tv/embed/******?wmode=direct&amp;autoplay=true" width="640" height="392" frameborder="no"></iframe></div><div id="2" style="margin-left: 0px; padding: 0px; float: left; width: 320px; height: 392px; border: 0px;"><iframe style="border: 0 none transparent;" src="//www.ustream.tv/socialstream/******" width="320" height="392" frameborder="no"></iframe></div><div id="addthisc" style="margin:0px; text-align: center; background-color:#0A0A0C; paddding: 0px 0px 0px 0px; width: 640px; height: 100%;  border:0px;"><div class="addthis_native_toolbox"></div></div>';
}
</script>


    <?php   
    };        
add_action( 'wp_head', 'mia_on_load_script' );

?>

Html网页测试代码如下：

<input type="button" onclick="change1()" value="change html in mydiv " />

此功能在 div 中更改 html：'mydiv' 单击按钮 "change html in mydiv "

而不是更改 html 单击带有 javascript 的按钮我想在从移动浏览器发出请求时在网页加载时更改它所以我决定使用 Mobile_Detect.php class (https://github.com/serbanghita/Mobile-Detect)

我之前的函数变成了：

function mia_on_load_script()
{
    // Not our page, do nothing
    if( !is_page( 'test' ) )
        return;
?>

         <?php   
 require_once(TEMPLATEPATH . '/MyScript/Mobile_Detect.php');
 $detect = new Mobile_Detect; 
 if ( $detect->isMobile() ) {
???????????????????????????????????????????????????????????
???????????????????????????????????????????????????????????
???????????????????????????????????????????????????????????
}

?>



    <?php   
    };        
add_action( 'wp_head', 'mia_on_load_script' );

?>

所以我必须插入哪个代码来代替问号以更改 html 来代替 'document.getElementById('mydiv').innerHTML'？谢谢

使用window.addEventListener('load', ...):

function mia_on_load_script()
{
    if(is_page('test'))
    {
        require_once(TEMPLATEPATH . '/MyScript/Mobile_Detect.php');
        $detect = new Mobile_Detect; 
        if($detect->isMobile())
        {
?>

<script> <!-- No "type" attribute for HTML 5 -->
window.addEventListener('load', function()
{
    document.getElementById('mydiv').innerHTML = '<div id="1" style="margin-left: 0px; padding: 0px; float: left; width: 640px; height: 392px; border: 0px;"><iframe style="border: 0 none transparent;" src="//www.ustream.tv/embed/******?wmode=direct&amp;autoplay=true" width="640" height="392" frameborder="no"></iframe></div><div id="2" style="margin-left: 0px; padding: 0px; float: left; width: 320px; height: 392px; border: 0px;"><iframe style="border: 0 none transparent;" src="//www.ustream.tv/socialstream/******" width="320" height="392" frameborder="no"></iframe></div><div id="addthisc" style="margin:0px; text-align: center; background-color:#0A0A0C; paddding: 0px 0px 0px 0px; width: 640px; height: 100%;  border:0px;"><div class="addthis_native_toolbox"></div></div>';
});
</script>

<?php
        }
    }
}
add_action('wp_head', 'mia_on_load_script');
