JQuery prevents click double clicking from submitting and passing dynamic functions or multiple parameters multiple times

Today is written about JQ double click event to prevent multiple commit problems, and through the function can be defined in bulk, more versatile, through the method of dynamic binding element events. You can also pass the function name dynamically or multiple arguments, etc. (this example only passes the function name through the Eval call).

We all know that in jQuery's event binding, a double-click event (dblclick) is triggered when executed. That is, a tag element (such as div, etc.), if the element is bound with a click event (click) and a double-click event (dblclick), then the double-click event (dblclick) will not be triggered when the single-click event (click) is executed, but the double-click event (dblclick) will be triggered twice when the double-click event (dblclick) is executed.

Let's take a look at the sequence of click events:

Mousedown, mouseout, click;
Double click (dblclick) : mousedown, mouseout, click, mousedown, mouseout, click, dblclick;

In a double click event (dblclick), the first click is masked, but not the second click. That is, a double-click event (dblclick) returns both a single-click event (click) result and a double-click event (dblclick) result. Instead of a double click event (dblclick) result and a double click event result (click).

In this case, the problem is solved by eliminating the extra one-click event.

The effect is as follows:

//Dynamically binds the events of the element through the method
