javascript - ng-repeat does not update after changing data -


UPDATE

  1. कोणीय की सेवा का उपयोग करें।
  2. कॉलबैक में $ scope.items सेट करें।

धन्यवाद सिलवेन और चेन-त्सू लिन।

मैं अंगुल के लिए एक नौसिखिया हूँ जो सीमित अंग्रेजी बोलता है यह एक बहुत ही सरल प्रश्न हो सकता है।

जब डेटा में परिवर्तन होता है तो मैं एक आइटम सूची प्रदर्शित करने की कोशिश कर रहा हूं। लेकिन, मैं सूची को नहीं देखता, जब तक कि मैं कोड चलाने से पहले आइटमों को इनट नहीं करता।

html code: 

  & lt; ul ng-controller = "testcontroller "& gt; & Lt; li एनजी-दोहराने = "आइटम में मद" & gt; {{item.description}} & lt; li & gt; & Lt; / ul & gt;

जेएस कोड: 

  फ़ंक्शन testControler () {var items = [] var डेटा = [{description: 'food'}, {description: ' फल}}} सेट टाइमआउट (फ़ंक्शन () {आइटम = डेटा}, 2000) $ scope.items = item}

$ टाइमआउट का उपयोग करें setTimeout के बजाय करें; इस तरह आप कोणीय दुनिया में रहते हैं कॉलबैक में $ scope.items भी सेट करें। 

  फ़ंक्शन testControler ($ टाइमआउट) {$ scope.items = []; Var डेटा = [{विवरण: 'भोजन'}, {वर्णन: 'फल'}] $ टाइमआउट (फ़ंक्शन () {$ scope.items = डेटा}, 2000)}

Python, converting png to gif using ImageMagick -

I am using Python 2.7.6, I had a problem converting some PNG files into GIF (an animation To create) os.system ("Convert-dated 1-Digiage background + page" + str (output_dir) + "/*.png -loop 0" + str (output_dir) + "/ Animation GIF") This was the error on which I have Parametre non welde - 1 Enough to go Without error, this is only an estimate, but ... If there is an empty space or quote in output_dir or other special characters, to avoid or quote you Nothing is doing, so your command line will look something like this: Convert - Day 1-digest background + page ~ / My image / *. Png -loop 0 ~ / My Photos / Animation.gif There may be a completely valid argument for sending ~ / my for input, and Pictures / *.
