jQuery prevents click double-click from multiple submissions and passing dynamic functions or multiple parameters_jquery

May 16, 2016 pm 04:53 PM

Today I am writing about the problem of JQ's double-click event preventing multiple submissions, and it can be defined in batches through functions, which makes it more versatile and dynamically binds elements' events through methods. And you can dynamically pass function names or multiple parameters (this example only passes the function name and call it through Eval).

We all know that in jQuery's event binding, two click events (click) can be triggered when executing a double-click event (dblclick). That is, a label element (such as div, etc.), if the element is bound to both a click event (click) and a double-click event (dblclick), then when the click event (click) is executed, the double-click event (dblclick) will not be triggered, and the double-click event will not be triggered. event (dblclick) will trigger two click events (click).

First look at the execution sequence of click events:

Click (click): mousedown, mouseout, click;
Double-click (dblclick): mousedown, mouseout, click, mousedown, mouseout , click, dblclick;

In the double-click event (dblclick), among the two click events (click) triggered, the first click event (click) will be blocked, but the second one will not meeting. That is to say, the double-click event (dblclick) will return the result of a click event (click) and the result of a double-click event (dblclick). Instead of the result of a double-click event (dblclick) and the result of two click events (click).

In this case, just eliminate the extra click event (click) and the problem will be solved.

The effect is as follows:
