Question

我正在尝试使用Javascript自动将LTR样式调整为RTL。

由于某种原因，Div元素不受影响

这是我的HTML：

<html>
    <head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script type="text/javascript" src="rtl.js"></script>
    <style type="text/css">
    .r  {float: right;}
    .l  {float: left;}
    </style>
    </head>
    <body>
    <div class="l">A</div>
    <div class="r">B</div>
    </body>
</html>

这是rtl.js的内容

                $el.css(css_prop,'');//clear styling
            }
        }
        applyStyles($el,css_props,css_vals);
        $el.css('diretion','rtl');


        this.addClass(rtl);
    });
}

jQuery(document).ready(transform_rtl);

Answer 1

将jQuery('*').each(function() {替换为$(document).children('*').each(){。我猜这应该有效！

遍历所有HTML标记并修改其样式
