When applied to the Manage icon, such as long press the show delete flag, click Cancel to remove the flag.In the FMX gesture management, only long press LONGTAP, tap Tap is a separate event and cannot be managed in the same event.After executing the LONGTAP, tap will also be triggered?, the solution, to determine whether long press and click the same position:Add
Recently in the use of zepto.js, found a bug in its Tap event, the product and test students repeatedly searched after several times, finally decided to study the source of Zepto, and solve the problem.Bug Case Description:A tap event is bound to a page However, after you swipe the page a few times, or swipe out of the mobile screen while sliding, and then click the button, you will find that the first clic
I. Definition and classification of events1. Click eventClick event, similar to PC-side click, but in the mobile side, the trigger of continuous click has a delay of 200ms ~ 300ms2.

1. What is "the point of penetration"?You may have encountered a pop-up layer on the list page, a popup layer with a close button, and after you click the button to close the popup layer, the content below the button will also perform a click event (or Open link). This is defined as a "point through" phenomenon.In the previous project encountered a problem such as: the Click on the pop-up selection component in the upper right corner of the completion will let the completion of the input box aft

This is defined as a "point through" phenomenon.Before, I also heard the tap point through the problem, think of blocking the default event or bubbling is good, but tried for a long time did not work, so on the Internet to che

Touch screen Click because there is a double-click judgment so there is a 200ms delay, zepto in the Touch.js compatibility is not good, so tap can not be used directly.There is a fastclick too big on the Gibhub.Use touched to write a simple analog tap event and add E.preventdefault () inside to prevent the system from default behavior./* Impersonation Tab Event @obj: element @callback: callback function */f

The system consists of a monitoring center and various monitoring sites. The data collection termi
I thought everyone already knew that one of the features of Apple's new MacBook was the installation of a touch pad with pressure sensing.
