# _script_loader.html 　　其文件路徑為：horizon\horizon\templates\horizon\client_side\_script_loader.html。將它復制到我們的主題目錄中：horizon\openstack_dashboard\themes\maintenance\templates\horizon\client_side\_script_loader.html。它里面的代碼為： ~~~ <script type="text/javascript" charset="utf-8"> /* Added so that we can append Horizon scoped JS events to the DOM load events without running in to the "horizon" name-space not currently being defined since we load the scripts at the bottom of the page. */ var addHorizonLoadEvent = function(func) { var old_onload = window.onload; if (typeof window.onload != 'function') { window.onload = func; } else { window.onload = function() { old_onload(); func(); } } } </script> ~~~ 　　這里面的代碼，我們不需要動的，所以這個文件也不需要放進我們的主題中，直接用默認的就行了。
