jquery - Is it possible to use javascript to download JSON object from another domain/server? -


यह कोड किस तरह दिखता है?

उस डोमेन / सर्वर को JSONP का समर्थन करने की आवश्यकता है, जो मूलतः कॉलबैक में JSON को लपेटता है।

jQuery में, कॉल इस प्रकार दिखाई देगी: 

  $। GetJSON ('http://otherdomain.com/api/whatever?callback=?', {Key: 'value', otherkey: true}, फ़ंक्शन (डेटा) {// हैंडल प्रतिक्रिया} );

अन्य सर्वर से वास्तविक प्रतिक्रिया (अगर आपने देखा कि वास्तव में क्या भेजा जा रहा है) इस तरह दिखेंगे: 

  // इस यूआरएल के साथ: Http://domain.com/api/method?callback=the_callback_function_name // प्रतिक्रिया इस प्रकार दिखाई देगी: the_callback_function_name ({"json": "डेटा यहाँ"});

जब आप अतिरिक्त callback =? की आपूर्ति करते हैं, तो jQuery के जेजोन विधि स्वचालित रूप से JSONP को संभालती है। बस कुछ साइटों को ध्यान में रखें जैसे कि json_callback =? महत्वपूर्ण हिस्सा यह है कि आप इसे यूआरएल के भाग के रूप में शामिल करते हैं और कॉलबैक जोड़ने की कोशिश मत करें: डेटा से getJSON < / कोड> फ़ंक्शन।

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...
