javascript getElementById 并将其转换为字符串

Question

有没有办法将 javascript HTML 对象转换为字符串？即

var someElement = document.getElementById("id");
var someElementToString = someElement.toString();

提前致谢

Answer 1

如果你想要整个标签的字符串表示，那么你可以为支持它的浏览器使用 outerHTML:

var someElementToString = someElement.outerHTML;

对于其他浏览器，apparently you can use XMLSerializer :

var someElement = document.getElementById("id");
var someElementToString;

if (someElement.outerHTML)
    someElementToString = someElement.outerHTML;
else if (XMLSerializer)
    someElementToString = new XMLSerializer().serializeToString(someElement);
