是否有任何解决方法可以让Jquery-ui在基于Android或IOS的触控设备上进行排序?
答案 0 :(得分:32)
我建议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。

The other answer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解决这两个问题。

我终于找到了一个适用于拖动手柄的解决方案。
$('.handle').addTouch()
答案 3 :(得分:2)
我正在使用下面的这个片段与jquery-sortable一起使用,它允许在我的iPhone上进行拖动排序。我完成第一次排序后遇到问题,因为列表中的任何滚动都被检测为拖动。
编辑 - 也见http://bugs.jqueryui.com/ticket/4143 编辑2 - 如果我使用整行作为句柄,我能够使这个工作。它还解决了滚动后偏移量不正确的问题。

这是否意味着要替换mouse.ui js代码或者在加载javascript后调用?我无法在Android平板电脑上为我工作。
为将来发现这一点的人编辑 - 使用以下代码将其用于三星Galaxy Android平板电脑:
/iPad|iPhone|Android/.test( navigator.userAgent ) && (function( $ ) {
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 ) {

这对我来说比选择的答案好得多,所以我希望这有助于其他人:

另一个代码表现得很奇怪,当你拖动一个元素时,潜在的丢弃位置离应该的位置很远。
