js报错 ：有详细错误提示

Uncaught InvalidStateError: Failed to read the 'selectionDirection' property from 'HTMLInputElement': The input element's type ('hidden') does not support selection.

谁遇到过这样的问题，一个页面有5个 input type=”hidden“ jquery报错

---

这错误提示不都说清楚了么，<input type="hidden"> 不支持 selection 特性

I made the same mistake.
I forgot get the hidden value.
I think u just wanner get the value,but forgot use val() method.

var projectInnerId = document.getElementById("projectInnerId").value;
