javascript - in MVC 5 how to pass selected value to html action in jquery ajax function -


When I select something from the user list, I am using jQuery AJAX to load some data. How can I pass the value of the options selected in the action parameters?

I tried making variables selected value but it says that the name "selectedValue" does not exist. 

  & lt; Script & gt; $ (Document) .ready (function () {$ ("# students"). Change (function () {var selectedValue = $ ("# students"). Val (); $ .ajax ({url: '@ url Type "GET", success: function (result) {$ ("# Notifications"). Html (results) (Action) ("Gate Data", "Sample", New {Table = "Student", ID = selected}), ;}});});}) & Lt; / Script & gt;

Are you using the correct variable? It seems that you are reading the value for selectedValue but try not to use it 

  var selectedValue = $ ("# students") . Val (); $ AZ ({url: '@ Url.Action ("GetData", "Sample")? Table = Student & amp; ID =' + Selected Value, Type: "GET", Success: Function (Results) {$ ("# Information "). Html (results);}});

This is named 2 values ​​named after your GetData action method table and id 

  Public Action Gate Data (string table, string id) {//: return something useful}

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
