Jquery-ui sortable不适用于基于Android或IOS的触摸设备

Question

是否有任何解决办法使Jquery-ui可以在基于Android或IOS的触摸设备上进行排序？

Answer 1

我建议使用jQuery UI Touch Punch.我已经在iOS 5和Android 2.3上测试了它,它在两者上都很好用.

Answer 2

另一个答案很棒但不幸的是它只适用于iOS设备.

此外,jquery.ui的更高版本导致了破坏,这意味着_touchEnd事件未正确重置mouse.ui中的内部标志(mouseHandled),这导致异常.

现在应该使用此代码修复这两个问题.

(function( $ ) {

    $.support.touch = typeof Touch === 'object';

    if (!$.support.touch) {
        return;
    }

    var proto =  $.ui.mouse.prototype,
    _mouseInit = proto._mouseInit;

    $.extend( proto, {
        _mouseInit: function() {
            this.element
            .bind( "touchstart." + this.widgetName, $.proxy( this, "_touchStart" ) );
            _mouseInit.apply( this, arguments );
        },

        _touchStart: function( event ) {
            if ( event.originalEvent.targetTouches.length != 1 ) {
                return false;
            }

            this.element
            .bind( "touchmove." + this.widgetName, $.proxy( this, "_touchMove" ) )
            .bind( "touchend." + this.widgetName, $.proxy( this, "_touchEnd" ) );

            this._modifyEvent( event );

            $( document ).trigger($.Event("mouseup")); //reset mouseHandled flag in ui.mouse
            this._mouseDown( event );

            return false;           
        },

        _touchMove: function( event ) {
            this._modifyEvent( event );
            this._mouseMove( event );   
        },

        _touchEnd: function( event ) {
            this.element
            .unbind( "touchmove." + this.widgetName )
            .unbind( "touchend." + this.widgetName );
            this._mouseUp( event ); 
        },

        _modifyEvent: function( event ) {
            event.which = 1;
            var target = event.originalEvent.targetTouches[0];
            event.pageX = target.clientX;
            event.pageY = target.clientY;
        }

    });
