JavaScript prototypes -


संभव डुप्लिकेट:

इस तरह एक प्रोटोटाइप बनाने में क्या अंतर है: 

  दिनांक.फू = फ़ंक्शन (बार) {अलर्ट (बार); };

और यह: 

  दिनांक.प्रोटीटिप.फ़ू = फ़ंक्शन (बार) {अलर्ट (बार); };

क्यों / जब मैं या तो का उपयोग करना चाहिए?

में पहला उदाहरण, foo एक कन्स्ट्रक्टर विधि है, इसकी तरह जावा में एक 'स्टैटिक' विधि। दूसरा एक वर्ग पर एक विधि foo को परिभाषित करने की तरह है - इसे उदाहरण के लिए स्कॉच किया गया है।

आप पहले जैसे 

  date.foo ()   
 और दूसरी तरह  
  दिनांक d = नया दिनांक () d.foo ()  
 
 या किसी अन्य विधि में दिनांक की तरह 
 
  this.foo ()

I can easily get it on the header and set it to my content, and now I want to set the tooltip in the code, to find out how to do it in xaml above. Cheers, Berryl Edit ========= Even Code for DayOfTheWeekColumn is. XML is part of the text book headers' visual tree, and nothing else I want to put in XML. I want to put it in the tooltip, however, is in the code, so I can set it there. I am thinking that the column headers should have the property of a child, which I can use to find the text box, but the haven has not been found yet....

wpf controls - Trigger on Image inside a Button WPF -

I want to control the visibility of the image in a button through a trigger: & lt; Button x: name = "notespanel" command = "{binding adddocument}" & gt; & Lt; Image x: name = "notes image" source = "notes" "height =" 32 "& gt; & gt; & gt; & gt; button & gt; 1 / What trigger will appear in the button or in the container that faces the button? 2 / How to set the visibility of the image? Thanks Zone Since you are updating the image, it should lie with the image (style of image as part) such as if the image is by default Is hidden, so I try the following Using R can choose to make it visible with toggleproperty1. DataTrigger binding = "{binding toggleproperty}" value = "1" & gt; & lt ; Setter Property = "Visibility" value = "View" />
