由 前提是你 提交于 2019-12-11 12:10:01
问题 I am working on a MVC application and I need to read resource file and get values , pass them in a javascript file. For this I am just calling a js function written in separate js file, from cshtml file. This function passes parameters which have the resource file value, to the function in javascript. Now in js file, I have another function in the same namespace as my above function where I need to read these resource file values. How can I do that? My cshtml code: <script type="text

returning array from function in javascript

由 浪尽此生 提交于 2019-12-11 11:40:09
问题 so I come from a heavy python background, and I'm trying to wrap my head around javascript. Here I have a function that returns an array of track IDs for soundcloud songs by the artist 'v-2-followers'. How would I go about assigning the output of SC.get(stuff) to a variable to reuse the track list in another function. I'm sure I'm missing something fundamental. I'm less looking for an answer that explains how to do this, but more why it's done like that. That said I would also very much

JavaScript: Reference a functions local scope as an object

由 匆匆过客 提交于 2019-12-11 11:34:07
问题 When I call a function, a local scope is erected for that call. Is there any way to directly reference that scope as an object? Just like window is a reference for the global scope object. Example: function test(foo){ var bar=1 //Now, can I access the object containing foo, bar, arguments and anything //else within the local scope like this: magicIdentifier.bar } Alternately, does anyone have a complete list of what is in the local scope on top of custom variables? Background: I'm trying to

Undefined Variable Inside Controller ($scope issue)

由 家住魔仙堡 提交于 2019-12-11 11:25:49
问题 All, I have the following AngularJS below. Why is $scope.gotData not visible outside of the call to getData.success() ? Note that $scope.gotData is visible to the view: I can display the value of scope.gotData by placing {{gotData}} within my index.html . Why can I not access $scope.gotData as a variable elsewhere in my controller? This is a question concerning the details of $scope. getData.js myApp.factory('getData',function($http){ return $http.jsonp('https://foo.com/bar.json') .success

问题 I am running 2 INSERTS inside a function. The first one is a non-entity framework INSERT (AD0.NET). The second one is an EntityContext.SaveChanges() Can I not nest both of these inside a Transaction Scope ? 回答1: Yes you can using (TransactionScope scope = new TransactionScope()) { InsertRecord(); context.SaveChanges(); scope.Complete(); } 回答2: As Eranga says it is perfectly feasible, if somewhat messy. See this link for peace of mind on TransactionScope Also consider setting the

问题 I am attempting to move away from spaghetti code in my jQuery plugins and work in a more structured manner. I am doing so by using the basic boilerplate template found here: https://github.com/jquery-boilerplate/jquery-patterns/blob/master/patterns/jquery.basic.plugin-boilerplate.js I also found the ToDo MVC plain jQuery code a source of inspiration because it doesn't chain many functions and keeps things nicely separated (I am not allowed to post more than two links due to my lack of status,

问题 I suppose this is a specific question, but for some reason, when I create a Thread like this: require_once(__DIR__.'/myotherfile.php'); class StreamBufferInput extends Thread { public function run(){ global $max_buffer_size; global $data_source; echo "DATA:" . $max_buffer_size; ... } } myotherfile.php has those two variables declared in it (and they can be accessed from other classes, but my echo statement here prints DATA: and nothing else. I couldn't find much on doing global variables

问题 I've a variable scope problem and I don't understand why this occurs and how to get rid of it : var items = ['foo', 'bar']; for (var index in items) { var item = items[index]; var selector = '.'+item+'-class'; $(selector).bind('click', function() { console.log("class: "+$(this).attr('class')); console.log("selector: "+selector); console.log("item: "+item); }); } Considers that this code execute itself over the following HTML : <div class="foo-class">Foo</div> <div class="bar-class">Bar</div>
