asp.net - Invoke server side method using XMLHttpRequest -

-

How can I call my own server-side function directly using XMLHttpRequest?

Assume that I have a static WebMath in my aspx file, how can I call it by XMLHttpRequest ASPN.NN? What is the header information to pass the engine and as a result, asp.net engine can implement my method and return the feedback in the outgoing stream.

This way I need to call my server side method 

  & lt; Script type = "text / javascript" & gt; Request var // A // This is a new function called when the user submits the form. // This example uses POST. Submit the functionCalback () {var inputValue = document.getElementById ("SearchInput"). Values; Var sendStr = "name =" + input value; Request = new XMLHttpRequest (); //b // specify the post method and send it Request.open ("Post", "Default.aspx / GetData"); Request.onreadystatechange = ready callback; Request.setRequestHeader ("content-type", "app / x-www-form-url expired"); Request.setRequestHeader ("islookup", "true"); Request.send (sendStr); } & Lt; / Script & gt;   
 Please guide me .... Thanks   
 
 
 me Believe you are probably referring to the methods of ASP.NET page when you say  a stable WebMath in my aspx file  ASP.Net page methods (or web service for consumption in JS). Uses JSON's serialization for P / O and P, so you need to set JSON as the content type for the request and Actually send the JSON string to the body i.e.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
