getCookie IE问题
getCookie IE问题
提问于 2012-03-27 06:43:37
我真搞不懂为什么下面的getcookie代码不能在IE中工作。这正是我想要的，并且在所有其他浏览器(FireFox、Safari、Chrome等)上都工作得很好。
我一直收到‘document.getElementByID(...)object Nodes.0’为空或不是对象...
请给我建议。
谢谢，JG

当textNodes只包含whiteSpaces时，IE会忽略它们，因此IE不会在元素中找到任何childNodes。
您可以使用以下命令：
try{document.getElementById("showname").childNodes[0].nodeValue = val_c[0];}
catch(e){document.getElementById("showname").appendChild(document.createTextNode(val_c[0]));}页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
