將php添加到javascript

Question

我正在嘗試將Wordpress頁面標題轉換爲JavaScript代碼，但所有我迄今嘗試的操作都無法使用。這是一個WordPress插件。當有人滾動頁面時，我想發起一個事件。整個插件的工作原理，但我想添加頁面標題的事件腳本應該是這樣的，以便在數據分析，看看哪些頁面，他們已滾動

_gaq.push(['_trackEvent', 'scroll', 'the page title', 'scrolled']); 

我與<php? the_title() ?>，get_the_title()品種試過，但我沒有管理。

這個插件運行在循環之外，所以我需要以某種方式獲得標題。任何人有想法？

Answer 1

當您從您的模板解決您的腳本的文件，你可以作爲一個GET參數添加標題腳本URL。您應該能夠讀取該文件中的標題。 然後在你的腳本文件中讀取$ _GET變量。

<script type="text/javascript" src="myscript.php?title=MY_PAGE_TITLE"></script> 

或者只設置在你的腦袋部分全球JS變量，你用PHP-填入值和參考，在腳本文件的變量。確保在腳本執行前設置變量！

<script type="text/javascript"> 
    var myTitle = '<?php echo $var_with_title; ?>'; 
</script> 

Answer 2

難道你不能使用JavaScript本機document.title？您的標題動態生成了嗎？ ？

_gaq.push(['_trackEvent', 'scroll', document.title, 'scrolled']); 

這樣

_gaq.push(['_trackEvent', 'scroll', <?php echo("'".the_title()."'"); ?>, 'scrolled']);
