问题描述
片段来了:
html = "<!doctype html>"; html += "<html>"; html += "<head><title>test</title></head>"; html += "<body><p>test</p></body>"; html += "</html>"; parser = new DOMParser(); dom = parser.parseFromString (html, "text/html");
尝试执行这些行时出现错误:
here's come the error when trying to execute these lines :
错误:组件返回失败代码:0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsIDOMParser.parseFromString]
我试图弄清楚发生了什么,但代码似乎是正确的,我在网上搜索,我来到这里没有任何线索.
I try to figure out what's going on but the code seems to be right and I searched on the web, i come here with no clues.
您以前遇到过这种故障吗?如果是,bug 隐藏在哪里?
have you encounter this failure before ? if yes, where's the bug hiding ?
推荐答案
您应该使用 JavaScript DOMParser 访问 innerHTML 和其他属性
