我发现如果页面是可滚动的,滚动之后如果要拖放项目(为了对ng-repeat列表进行排序),则拖动的元素在y轴上显示的距离与距离一样多在拖动元素之前,我已向下滚动页面。
我正在使用: https://github.com/angular-ui/ui-sortable
此处记录了此问题: https://github.com/angular-ui/ui-sortable/issues/286
我似乎无法调用ui.item.sort(' refreshPosition')方法。无论是通过编辑原始代码还是在我自己的控制器中确定是否应该这样做!?
这是我的相关模板代码:
<script type="text/ng-template" id="form_field_ref2">
<div ng-init="tmp = dbo.get(attobj.name)" ng-controller="sortController">
<!-- <div ng-model="tmp" ui-sortable="{ 'ui-floating': 'auto'}">-->
<div ng-model="tmp" ui-sortable="sortableOptions">
<div ng-repeat="dbo2 in dbo.get(attobj.name) track by $index" id="sort_{{$index}}" style="float:left; padding-right: 3px; padding-bottom: 5px;">
<div class="tag sortableTag">
<a href="#/view/{{ dbo2.cid }}" target="_blank">{{ dbo2.displayName() }}</a>
<a href="" class="glyphicon glyphicon-remove" ng-click="dbo.removeValue(attobj.name, $index)"></a>
</div>
</div>
</div>
</div>
<div ng-include="'typeaheadtemplate2'" style="width: 100%;"></div>
</script>
控制器:
app.controller('sortController', function ($scope) {
$scope.sortableOptions = {
'ui-floating': 'auto',
activate: function() {
console.log("activate");
},
beforeStop: function() {
console.log("beforeStop");
},
change: function() {
console.log("change");
},
create: function() {
console.log("create");
},
deactivate: function() {
console.log("deactivate");
},
out: function() {
console.log("out");
},
over: function() {
console.log("over");
},
receive: function() {
console.log("receive");
},
remove: function() {
console.log("remove");
},
sort: function() {
console.log("sort");
},
start: function(e, ui) {
console.log("start");
console.log(ui.item);
var tag= '#'+ui.item.context.id;
$(tag).sortable('refreshPositions');
// $(this).sortable('refreshPositions');
},
update: function(e, ui) {
console.log("update");
},
stop: function(e, ui) {
console.log("stop");
}
};
});

添加样式
overflow-y: auto;
到可以为我修复的可排序项目

问题在于,您尝试在refreshPositions
上调用ui.item.sortable
,refreshPositions
是ui-sortable用于存储数据的对象。您应该在可排序的元素上调用<script type="text/ng-template" id="form_field_ref2">
<div ng-init="tmp = dbo.get(attobj.name)" ng-controller="sortController">
<!-- <div ng-model="tmp" ui-sortable="{ 'ui-floating': 'auto'}">-->
<div ng-model="tmp" ui-sortable="sortableOptions">
<div ng-repeat="dbo2 in dbo.get(attobj.name) track by $index" style="float:left; padding-right: 3px; padding-bottom: 5px;">
<div class="tag sortableTag">
<a href="#/view/{{ dbo2.cid }}" target="_blank">{{ dbo2.displayName() }}</a>
<a href="" class="glyphicon glyphicon-remove" ng-click="dbo.removeValue(attobj.name, $index)"></a>
</div>
</div>
</div>
</div>
<div ng-include="'typeaheadtemplate2'" style="width: 100%;"></div>
</script>
。
试
app.controller('sortController', function ($scope) {
$scope.sortableOptions = {
start: function(event, ui) {
$(this).sortable({
sort: function(event, ui) {
var $target = $(event.target);
if (!/html|body/i.test($target.offsetParent()[0].tagName)) {
var top = event.pageY - $target.offsetParent().offset().top - (ui.helper.outerHeight(true) / 2);
ui.helper.css({'top' : top + 'px'});
}
}
});
}
};
});
控制器:
$ids = array_map( function( $arr ){
return $arr["id"];
}, $arr );
echo '<pre>'; print_r($ids);

$(".sortable").sortable({
sort: function(event, ui) {
ui.position.top = ui.position.top + $(window).scrollTop();
},
});
并添加“position:relative”可排序块
