javascript - How to input a function in a function -

-

मैं इस तरह एक हैक कर सकता हूँ: 

  function exec (fn) {setInterval ( fn, 0); } Exec ("newfn ()");

लेकिन एक क्लीनर की तलाश है।

जैसा कि पहले से उल्लेख किया गया है टिप्पणियों में, फ़ंक्शन को किसी अन्य फ़ंक्शन में पास करने का सबसे अच्छा तरीका यह है कि उसे संदर्भ पास करना, उसके नाम वाला स्ट्रिंग नहीं।

उदाहरण:

< पूर्व> फ़ंक्शन फ़ू () {console.log ('इनुसाइड फू'); } Exec (foo);

फ़ंक्शन के अंदर फ़ंक्शन निष्पादित करने के लिए, आपको फ़ंक्शन संदर्भ के बाद () डाल दिया है: 

  function exec Fn) {एफ एन (); }

लेकिन जब आप बिल्कुल ऐसा कर सकते हैं, मुझे exec (foo) over foo () ।

c# - Highlight all words containing a letter in a richtextbox -

Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...

Do you know about a problem due to Admob not being able to click on interstitial ads and therefore on Nexus 5 devices Have not brought any revenue? Fact: It does not have intermediate ads - some clickable, but mostly no . It comes with the old standalone Google Admob SDK and with the new Google Play Services SDK. It is on Nexus 5 with Android 4.4.2 , but it is possible that other devices are also affected. This happens in many programs in the Google Play Store - I'm not only with my application. For example, you can not Galaxy Nexus (Nexus 3), Galaxy S, on the HTC One. Below is a screenshot that opens the small info button in the clickable below the ad and OK, the Close X button also looks working properly , Though clicking on the ad does not happen - like it does not exist or something on it. Do you know of any solutions or possible solutions to the problem? Thanks! --- Update - - This activity declaration is: & amp; Activity Activity:...

I am trying to add a JTabbedPane to a panel, as well as for control I am using Migrates with the following buttons. However, I can not even get the JTabbedPane to fill without the buttons when they are not needed. The following SSCCE: public static zero main (string [] args) {jpn panel = new zpinal (new megallout (new lc.)
