angularjs - In Angular, what's the point of a service? -

-

इसमें, मैं इस कोड पर आया: 

  कोणीय मॉड्यूल ('myServiceModule', [])। नियंत्रक ('MyController', ['$ scope', 'notify', फ़ंक्शन ($ दायरा, सूचित करें) {$ scope.callNotify = function (msg) {सूचित करें (msg);};}]) फ़ैक्ट्री ('सूचित करें', ['$ window', फ़ंक्शन (जीत) {var msgs = [], रिटर्न फ़ंक्शन (msg) {msgs.push (msg); if (msgs.length == 3) {win.alert ( Msgs.join ("\ n")); msgs = [];}};}]);

मेरा प्रश्न यह है, क्यों नहीं यह बहुत आसान है और सिर्फ यह परिभाषित करता है कि $ scope.callNotify फ़ंक्शन के अंदर समारोह को सूचित करें?

यदि सेवाओं को सिर्फ कार्यों को कहीं और परिभाषित किया गया है, क्या एक ही चीज़ को पूरा करने के बहुत आसान तरीके नहीं हैं?

बस किसी दूसरे नियंत्रक में उस कोड को पुन: प्राप्त करने के बारे में सोचें; आप इसे करने में सक्षम नहीं होंगे।

लेकिन अगर आप इसे किसी सेवा में रख देते हैं, तो इसे इंजेक्ट किया जा सकता है और फिर हर जगह पुन: उपयोग किया जा सकता है।

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
