The normal idea is to clear the input content every time after getting the input file. I searched on Baidu and found that some methods use the reset of the form, but what if it is just a separate input="file" without the from element? Moreover, some of the methods found online have poor compatibility. Do experienced drivers have any reliable methods?

I just saw this method, how is the compatibility?

input.addEventListener('click', function() { this.value = ''; }, false);

Several ideas:
1. Set the value of input to '', the same as above.
2. Replace the current input with a new input
3. Remove the value attribute of the input.
