javascript - JS function receives parameters and pops up

Question

{Code...} can alert the contents of the box at once?

阿神 · Answer

Can’t. One sentence of alert() pops up the alert box once.

After closing an alert box, the next alert box will pop up.

You can concatenate two input values into a string, for example:

var myFn = function(a,b) {
        var str = a.value + '，' +  b.value;
        alert(str);        
    };

过去多啦不再A梦 · Answer

Can’t.

The pop-up window is executed synchronously. When alert(a.value); is called, the system will no longer execute (blocked). The pop-up window must be closed before the following code can continue to execute.

So, the solution is not to use the alert function, but to use a third-party pop-up window, which can pop up multiple ones at the same time.
