backbone.js - Backbone validation of complex object property (momentjs) -

-

मैं अपने मॉडल में momentjs ऑब्जेक्ट का उपयोग कर रहा हूं: 

  var MyModel = Backbone Model.extend ({defaults: {iamString: "नमस्ते", iamDate: moment ()}, सत्यापन: {iamString: {अपेक्षित: सत्य, fn: function (value, attr, computed state) {चेतावनी ('iamString का सत्यापन ! ');}}, IamDate: {अपेक्षित: सत्य, फ़ेन्ने: फ़ंक्शन (मूल्य, एट्रि, कम्प्यूटेटेड स्टेट) {चेतावनी (' आईमैडेट की मान्यकरण को बुलाया जाता है! ')}}}}, प्रिंट: फ़ंक्शन () {इसे वापस करें ('IamString') + '' + this.get ('iamDate') प्रारूप प्राप्त करें ('YYYY-MM-DD hh: mm: ss');}});

अगर मैं मॉडल को अपडेट करता हूं, तो iamString सत्यापन को बुलाया जा रहा है, लेकिन iamDate सत्यापन को कभी कॉल नहीं किया जा रहा है।

>

यहाँ है मैं iamDate सत्यापन कैसे संभव बना सकता हूं?

यदि आप क्षण कॉल करते हैं ) फ़ंक्शन, आपको प्रारूप को जोड़ना होगा। 

  $ ('# मान्य') क्लिक करें (फ़ंक्शन () (mymodel.set ({iamString: 'bye', iamDate: पल (' प्रारूप ('YYYY-MM-DD hh: mm: ss')}, {validate: true}); चेतावनी (mymodel.print ());});

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
