How to use

HTML structure

The mobile phone app's HTML structure for switching image effects is nested <div> html, with each picture card wrapped in div.demo__card, with pictures, descriptions, and additional layers.

<div class= "Demo__card" >
 <div class= "Demo__card__top Brown" >
 <div class= "Demo__card__img" ></div>
 <p class= "Demo__card__name" >hungry cat</p>
 </div>
 <div class= " Demo__card__btm ">
 <p class=" Demo__card__we ">Whatever</p>
 </div>
 <div class= "Demo__card__choice m--reject" ></div>
 <div class= "Demo__card__choice m--like" ></div>
 <div class= "Demo__card__drag" ></div>

M--reject is the layer that moves the picture to the left, M--like is the layer that moves the picture to the right, Demo__card__drag is the drag layer.

Javascript

In the jquery code, the Pullchange () function is used to set the rotation angle and transparency of the two sliding layers to the left and right. The release () function is used to determine whether the user slides the finger to the left or right and adds the corresponding class to the DOM element for these actions.

function Pullchange () {animating = true;
 deg = PULLDELTAX/10;
 $card. CSS (' transform ', ' Translatex (' + pulldeltax + ' px ') rotate (' + deg + ' deg) ');
 var opacity = pulldeltax/100; var rejectopacity = opacity >= 0?
 0:math.abs (opacity); var likeopacity = opacity <= 0?
 0:opacity;
 $cardReject. CSS (' opacity ', rejectopacity);
$cardLike. CSS (' opacity ', likeopacity);
}
;
 Function Release () {if (Pulldeltax >= decisionval) {$card. addclass (' to-right ');
 else if (pulldeltax <=-decisionval) {$card. addclass (' To-left ');
  } if (Math.Abs (pulldeltax) >= decisionval) {$card. addclass (' inactive ');
   settimeout (function () {$card. addclass (' below '). Removeclass (' inactive to-left to-right ');
   cardscounter++;
    if (Cardscounter = = numofcards) {cardscounter = 0;
   $ ('. Demo__card '). Removeclass (' below ');
 }, 300);
 } if (Math.Abs (Pulldeltax) < Decisionval) {$card. addclass (' reset '); } settimeout (function () {$card. attr (' style ', '). removeclAss (' reset '). Find ('. Demo__card__choice '). attr (' style ', ');
  Pulldeltax = 0;
 animating = false;
}, 300);  };

Finally, the MouseDown and touchstart events are monitored and a card switching operation is performed on the card elements that are not. Inactive.
