Can anyone assist?<script type="text/javascript">//... getAttr: function(ele, attr) { if (typeof ele.attributes[attr] == 'undefined'){ return ele.getAttribute(attr); } else { return ele.attributes[attr].nodeValue; } },//...</script><div> <a href="http://www.yo.com#foo">Link</a></div>使用上面的html，在每个浏览器中，我如何getAttr（ele，'href ）？ （假设选择ele节点不是问题）using the above html, in each browser, how do I getAttr(ele, 'href')? (assume selecting the ele node isn't an issue)推荐答案关于你的问题的更新，你可以试试这个。With regard to your question's update, you could try this.它可能有点过分，但如果 getAttribute（）并且点表示法不返回结果，则遍历属性对象以尝试查找匹配。It may be overkill, but if getAttribute() and the dot notation don't return a result, it iterates through the attributes object to try to find a match. 示例： http://jsfiddle.net/4ZwNs/var funcs = { getAttr: function(ele, attr) { var result = (ele.getAttribute && ele.getAttribute(attr)) || null; if( !result ) { var attrs = ele.attributes; var length = attrs.length; for(var i = 0; i < length; i++) if(attrs[i].nodeName === attr) result = attrs[i].nodeValue; } return result; }};var result = funcs.getAttr(el, 'hash');但是，您可以自行进行一些跨浏览器测试。 ：o）It's up to you to do some cross-browser testing, though. :o)使用 ele.attributes ，你需要按索引访问它们，如：Using ele.attributes, you need to access them by index, as in:ele.attributes[0].nodeName; // "id" (for example)ele.attributes[0].nodeValue; // "my_id" (for example)尝试传递属性属性名称似乎返回 typeof object 的值，所以你的 else 代码正在运行，即使 ele.attributes [attr] 没有为您提供所需的值。Trying to pass attributes an attribute name appears to return a value whose typeof is object, so your else code is running even though ele.attributes[attr] doesn't give you the value you want. 这篇关于跨浏览器，javascript getAttribute（）方法？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
