html - Is it "safe" to use schemeless protocol URIs on public websites? Ex. //www.example.com/dir/file -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 6 जवाब

एचटीएमएल में छवियों को संदर्भित करते समय, सीएसएस, जावास्क्रिप्ट, इत्यादि ... मैं कभी-कभी http या https स्कीम भाग के बिना लिंक का उपयोग करते हैं। & lt; img src = "// www.example.com/dir/file.gif" alt = "" / & gt; और मेरे पास अभी तक किसी भी ब्राउज़र पर गड़बड़ी नहीं हुई है (मुझे पता है का)। मैंने देखा है कि कुछ अन्य सार्वजनिक साइट इसका इस्तेमाल भी करते हैं, लेकिन कई नहीं।

मैं ई-कॉमर्स साइट पर इस सिंटैक्स के साथ Google jQuery सीडीएन का संदर्भ भी देता हूं: 

 < कोड> & lt; script src = "// ajax.googleapis.com/ajax/ .." प्रकार = "टेक्स्ट / जावास्क्रिप्ट" & gt; & lt; / script & gt;

जाहिर है, मैं केवल ऐसा करता हूं जब मुझे पता है कि सर्वर के दोनों http और https क्षमताओं हैं

तो मेरा सवाल है यह क्या नुकसान हो सकता है? क्या नुकसान या डाउनसाइड?

यह किसी भी तरह से नुकसान नहीं पहुंचाएगा। दरअसल, यदि आप src = "http://ajax.googleapis.com/ajax/ .. लिखते हैं और आपका उपयोगकर्ता साइट को HTTPS पर ब्राउज़ करेगा तो ब्राउजर उस साइट को चेतावनी देगा कि साइट के कुछ हिस्सों को HTTP का उपयोग करना है। ऐसे मामलों के लिए संकेतन।

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
