当PhpStorm猜测JavaScript函数的参数错误时，该如何纠正？

Question

Looking around this seems to be the closest it comes to being an answer to my problem. However it causes other issues...

---

This is my situation:

$element.insertBefore($container);

This line has a warning that insertBefore has an “ Invalid number of arguments, expected 2 ”

/** @type {function(target)} */
$element.insertBefore;
$element.insertBefore($container);

These three lines have a warning, but for a different reason. The third line no longer has any warning about an invalid number of arguments; however the second line is now concerned that the “ Expression statement is not assignment or call ”.

I tried a number of other configurations however none of them seem to affect the first warning in any way… but they don't create new warnings. Some of these variations are as follows:

/** @type {function(target)} */
/* $element.insertBefore; */
$element.insertBefore($container);

—

/** @type {function(target)}
$element.insertBefore; */
$element.insertBefore($container);

—

/** @type {function(target)} */
$element.insertBefore($container);

I was just wondering if anyone could give me pointers on what I'm doing wrong or if this warning is just an irreversible mistake for the system right now.

PS This is actually JavaScript code… I just have a habit of prefacing variables that are instances of jQuery objects with a dollar sign. This means that the above calls to insertBefore are calls to the jQuery function not the vanilla JavaScript function.

似乎insertBefore（）确实需要2个参数： https : //www.w3schools.com/jsref/met_node_insertbefore.asp
