asp.net mvc - why when my action returns a view - it passes first through a javascript function -


in index view have button javascript function when it's clicked:

<script>     function addcat() {         $.ajax({             type: "get",             url: '@url.action("addcategory")',             data: {},         });     } </script>  @html.dropdownlist("languages", new selectlist(model.lstlanguages, "languageid", "name", session["langid"] ?? "1"), new { id = "ddllanguages" }) <div id="categoriesplace"></div> <input type="button" id="btnaddcategory" onclick="addcat()" value="addcategory" />

when click on button, see should redirected addcategory action, adds record in database , returns addcategory view. problem when reaches drop-down in addcategory view, goes straight addbtn_click() function if it's clicked , redirects me index action. can explain behavior?

so, here categorycontroller:

public class categorycontroller : controller {     public actionresult addcategory()     {         categoryviewmodel vm = new categoryviewmodel();         vm.addnewcategory();         return view(vm);     }      public actionresult addcategorieslanguages(int catid, int lanid, string title, string shrtdescription, string description)     {         categoryviewmodel vm = new categoryviewmodel();         vm.addcategorieslanguages(catid, lanid, title, shrtdescription, description);         return redirecttoaction("index");      } }

and, here addcategory view:

@model onion.web.viewmodels.categoryviewmodel  @{     viewbag.title = "addcategory"; }   <h2>addcategory</h2> @html.dropdownlist("languages", new selectlist(model.lstlanguages, "languageid", "name",@httpcontext.current.session["langid"]),new { id = "ddllanguages" }) <br /> <label for="txbtitle">title:</label> <input type="text"  id="txbtitle"/>  <br /> <label for="txbshortdescription">short description:</label> <input type="text"  id="txbshortdescription" />  <br />  <br /> <input type="button" id="btnadd" onclick="btnadd_click" value="add" />  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>   <script>     function btnadd_click() {             $.ajax({             type: "get",             url: '@url.action("addcategorieslanguages")' + '?catid=' +@model.newcategoryid +'&lanid=' + $("#ddllanguages").val() + '&title=' + $('#txbtitle').val() + '&shrtdescription=' + $('#txbshortdescription').val() + '&description=' + $('#txbdescription').val(),             data: {}         });     } </script>

in addcategory view, try changing button's onclick attribute include function name , parenthesis shown below:

<input type="button" id="btnadd" onclick="btnadd_click()" value="add" />

i not 100% sure if issue, stood out me.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
