javascript - jQuery not updating div -

-

मेरे पास एक तत्व है: 

  & lt; div id = "foo_ & lt ;? PHP echo $ id;? & Gt; " वर्ग = "छिपा" & gt; & lt; / div & gt;

मैं कोशिश कर रहा हूं 

  यदि ($ ("# foo_" + id) .is (': hidden')) {// stuff $ ("#foo_" + id)। Html (html) .slideDown ('तेज'); }

मैंने बार-बार चेक किया है, div foo_233 फायरबग में पाया जा रहा है और छिपा हुआ दिखाया जा रहा है आईडी को जावास्क्रिप्ट फ़ंक्शन पर सही ढंग से पास किया गया है। लेकिन अभी भी उपरोक्त लाइनें काम नहीं कर रही हैं क्या गलत हो सकता है? यह बहुत निराशाजनक है ..

आपके चयनकर्ता में स्थान: 

  अगर ($ ("# foo_" + id) .is (': hidden')) {// सामान $ ("# foo_" + id)। Html (html) .slideDown ('fast'); }

इसे से छुटकारा पाएं: 

  यदि ($ ("# foo_" + id) .is (': hidden')) {// सामान $ ("# foo_" + id) .html (html) .slideDown ('तेज'); }

संभवतः, आपके डिवी आईडी को "foo_5" जैसा दिखना चाहिए, लेकिन आपके द्वारा बनाई गई चयनकर्ता "foo_ 5" था, जो यही वजह है कि यदि आपकी स्थिति कभी भी true के लिए मूल्यांकन नहीं करती है।

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
