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.
