我是js的新手,我有这样的代码,它将设置上传文件的路径:
document.getElementById("binaryFilePath").value = "location"
当我跑步时,我得到:
[Error] InvalidStateError: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable.
global code (AppAdmin, line 1)
发生了什么事?
答案 0 :(得分:-1)
你在找这个吗?
function myFunction()
{
var x = document.getElementById("myFile").type;
document.getElementById("demo").innerHTML = x;
}
