我正在使用jQuery(".mySearch").ajaxlivesearch({
loaded_at: <?php echo time(); ?>,
token: <?php echo "'" . $handler->getToken() . "'"; ?>,
max_input: <?php echo Config::getConfig('maxInputLength'); ?>,
url: <?php echo (APPPATH."/third_party/jQueryLiveSearch/core/AjaxProcessor.php"); ?>
onResultClick: function(e, data) {
// get the index 1 (second column) value
var selectedOne = jQuery(data.selected).find('td').eq('1').text();
// set the input value
jQuery('#ls_query').val(selectedOne);
// hide the result
jQuery("#ls_query").trigger('ajaxlivesearch:hide_result');
},
onResultEnter: function(e, data) {
// do whatever you want
// jQuery("#ls_query").trigger('ajaxlivesearch:search', {query: 'test'});
},
onAjaxComplete: function(e, data) {
}
});
(1.1.4.129-beta)显示Rg.Plugins.Popup
。我正在使用以下代码显示popupimage
。
popuppage
我的问题
有时会显示两次弹出窗口。
发布情况
首先,我从一个await PopupNavigation.Instance.PushAsync(new UploadImagePopupPage(imagepath), true);
像下面这样叫popupimage
。
contentpage
在//Checking one condition
if (_images.Count != 0)
{
await PopupNavigation.Instance.PushAsync(new UploadImagePopupPage(picturepath), true);
}
中添加了以下代码以显示图像:
UploadImagePopupPage
然后从popupimage.Source = picturepath;
发出单击以下按钮的消息,如下所示。结果,UploadImagePopupPage
中的下一张图像将显示为弹出窗口。
observablecollection
然后再次从初始页面调用MessagingCenter.Send<UploadImagePopupPage>(this, "complete");
,如下所示:
popupimage
我实现了这个目的,以MessagingCenter.Subscribe<UploadImagePopupPage>(this, "complete", (sender) =>
{
ShowImagePopUp();
});
public async void ShowImagePopUp()
{
try
{
//Removing current popup
await PopupNavigation.Instance.PopAsync();
//Checking one condition
if (Utility.picturecount < _images.Count)
{
// Following popup code invoking 2 times
await PopupNavigation.Instance.PushAsync(new UploadImagePopupPage(_images[Utility.picturecount]), true);
}
else
{
_images.Clear();
await Navigation.PopModalAsync();
}
Utility.loadPhotoAlbum = true;
}
catch (Exception e)
{
Debug.WriteLine("Exception:>>"+e);
}
}
的形式将observablecollection
图像一一显示。弹出页面中有一个按钮,单击该按钮时只会出现下一个弹出窗口。有人面对这类问题吗?
答案 0 :(得分:2)
您需要取消订阅OnDisappearing
中的活动
protected override void OnDisappearing()
{
base.OnDisappearing();
MessagingCenter.Unsubscribe<UploadImagePopupPage>(this, "complete");
}
