JQuery Event-DblClick () method

JQuery Event Reference Manual

Instance

When you double-click a button, the element is hidden or displayed:

$ ("button"). DblClick (function () {  $ ("P"). Slidetoggle ();});

Try it yourself.

Definition and usage

The DblClick event occurs when you double-click an element.

A click occurs when the mouse pointer rests over the element and then presses and releases the left mouse button.

A double click event occurs two times in a short period of time.

The DblClick () method triggers the DblClick event, or a function that runs when the DblClick event occurs.

Tip: If you apply the DblClick and click events to the same element, problems may arise.

Triggering the DblClick event syntax

$ (selector). DblClick ()

Try it yourself.

Bind a function to the DblClick event syntax

$ (selector). DblClick (function)

Parameters	Description
function	Optional. Specifies the function that runs when the DblClick event occurs.

Try it yourself.

JQuery Event Reference Manual

Example 2:

In the event bindings for jquery, you can trigger two click events (clicks) When you perform a double-click event (DblClick). That is, a tag element (such as a Div, and so on), if the element is bound at the same time by clicking Event (click) and double-click event (DblClick), the double-click event (DblClick) is not triggered, and the double-click event (DblClick) is executed. The two-click event is triggered.

　　Let's take a look at the execution order of the Click events:

Click: Mousedown,mouseout,click;
Double-click (DblClick): Mousedown,mouseout,click, Mousedown,mouseout,click,dblclick;

In a double-click event (DblClick), the two-click event that is triggered (clicking), the first click event is masked out, but not the second time. That is, a double-click event (DblClick) Returns the result of a single clicking event and a double click event (DblClick). Instead of a double-click event (DblClick) result and two click event Results (clicks).

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

SetTimeout

In jquery's $ (document). Ready (function () {}), write directly inside:

//Defining SetTimeout Execution methods
var timefn =Null

$(‘Div'). Click (function () {
 // Cancel the method that was not executed last time  
 Cleartimeout (TIMEFN); 
 // execution delay  
 Timefn = SetTimeout (function () {
 //do Function here writes the code for the click event to execute  
},300); 
}); 
 
 $ ( "div"). DblClick (Functin () {
 // cancellation of methods not performed last delay  
 Cleartimeout (TIMEFN); 
 // Double-click the execution code of the event  
})  

From the test results, if the time of two clicks is around 300ms, it is still easy to see the click and DblClick events being called simultaneously, and if the interval is shorter or longer, there will only be a click or DblClick event.

At this point, you can avoid triggering a click when you double-click (DblClick) to some extent.
