BackBone.js : "_ cannot be resolved" - backbone.js

I am trying to retrieve list of object from Server and render it on html using Backbone.js
But facing "- cannot be resolved" error.
My code is as follows:

Any help/suggestion for this problem is highly appreciated.

It looks like you are mixing Java and Javascript. When you do something like:
<% _.each(products, function(product){ %>
in a JSP file, it gets treated as Java code. However, the code you have inside the <% %> block:
_.each(products, function(product){
is Javascript code.
Since you can't combine the two different languages of Java and Javascript you get a Java error (the JasperException).

AngularJS Multi-level forms

I am kind of new to AngularJS and is now facing with an issue. When I browse the solution and select an item from any category it updates the all the sections textboxes with the result instead of the on intended section.
If I have only one section then everything is perfectly fine but the moment I have more than one section, then everything goes for a toss. I know this is because of the $scope variable currentItem. I am not sure how I can solve this issue.
Any light thrown to solve the issue is highly appreciated. Thank you in advance.

How to fetch the data of a specific model from the collection list that is present to the user in backbone.js?

I have a list view that displays some contents from the api and along side a button that when clicked should show the details of the corresponding item from the list-view on another page, how to associate the button to the specific id and how to present a generic url that accepts these ids to route accordingly. I saw many similar posts but I didn't know how to route those or can't understand how each model is called at that route. Here's my current app, where I've not generalised the routing instead each button is associated to the first id and a route like /1 which takes it to a view to display details of the first element from the collection alone.

//initializing router and setting up history for routing to work
var pageRouter = new PageRouter();

I tried this, later, I associated the data-id with the button and gave the model.id I fetched from the api and then got the id on click and then passed the model to be rendered on the detail-view.
Still this doesn't change the router in anyway so still looking for a better way to do it.
Edit
Updated the code and fixed by associating model id with href, and created routes to fetch and get the model from in the router function.

Im unable to reload the list data when I click on button using angularjs

step1: Initially while page load $scope.results is empty arrayList
step2: When I click on search button I am unbale to load the data in table
1) test.js
While page loading results is empty
myApp.controller('HomeController', ['$scope', '$http','$location', '$rootScope', 'DataService','SearchService',
function($scope, $http, $rootScope, $location, DataService,SearchService) {
$scope.results = [];
$scope.searchSubmit = function(){
$scope.dashboardflag = true;
$("#dashboard").hide();
SearchService.getSearchResults.query({searchText:$scope.searchText,
startDate:$("#startDate").val(),endDate:$("#endDate").val(),
userId:$scope.userEntity.userid,managerId:101083,
status:'Answered',threadType:'REPLY',
pageNumber:0
},function(data) {
//var data1 = data.list;
$scope.$apply(function() {
$scope.results = angular.copy(data);
});
});
$("#searchResults").show();
};
}]);
2) test.html
Search
<table id="searchObjResults" border="1">
<tr>
<th>Assignto</th>
<th>Title</th>
<th>Id</th>
<th>Status</th>
<th>Workflow</th>
<th>Assignment date</th>
</tr>
<tr ng-repeat="obj in results">
<td>{{obj.userName}}</td>
<td>{{obj.threadTitle}}</td>
<td>{{obj.threadId}}</td>
<td>{{obj.threadStatus}}</td>
<td>{{obj.threadType}}</td>
<td>{{obj.assignedDate}}</td>
</tr>
</table>
Couple of things,
first if you already posted you html, please post the full html,
where is the ng-app, and your controller?
second, if you want to show\hide elemets maybe you should concider using ng-hide and add a some var to the scope that wlil control that
https://docs.angularjs.org/api/ng/directive/ngHide
also, is the "data" returning from the sevice is an array?
please console.log the result, for more info
Here is the example. It may help you to follow. If no data found, then table will not be shown to the user.

I want to render a table in which i will show some info in its caption and other details as its rows. But only caption part is rendering while rows are missing. even that is without any error. How to solve this?? any better way to achieve this???
For above code; i am using:
Backbone.js 1.0.0
MarionetteJS v1.0.3
jQuery JavaScript Library v1.9.1
Underscore.js 1.4.4

Seriously i unable to find my issue here to fix it. as well any one suggest me to find the issue for backbone.js online..
so let me keep check my code..
Thanks in advance..
Pretty sure it is to do with this line in your HTML
<td><%= <a hre="#/edit/<%= user.id %>" class="btn">Edit</a></td>
You open the <%= and then open it again /edit/<%= which I think is causing the problem. Even if opening it twice is allowed, you haven't added a final %> to the line.
Play around with that and let us know how it goes.
EDIT
Try this instead
<td> Edit</td>
You shouldn't need to wrap the entire thing in the <% and %> tags, just the part you want to output.
