Loading a template in Backbone.js - backbone.js

I am on beginner level on Backbonejs. I am trying to call simple template. But it's giving me below error:
*Uncaught TypeError: Cannot read property 'replace' of undefined*
See plnk which I have created for it:
http://plnkr.co/edit/fTcL4m?p=info
You can also find code here:
<!DOCTYPE html>
<html>
<head>
<title>Loading a template</title>
</head>
<body>
<h1>Loading a template</h1>
<div id="search_container"></div>
<script data-require="jquery#2.2.0" data-semver="2.2.0" src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<script data-require="underscore.js#1.8.3" data-semver="1.8.3" src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
<script data-require="backbone.js#1.1.2" data-semver="1.1.2" src="//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js"></script>
<script>
SearchView = Backbone.View.extend({
initialize: function(){
this.render();
},
render: function(){
var template = _.template($("#search_template").html(), {});
this.el.html(template);
}
});
var search_view = new SearchView({ el: $("#search_container") });
</script>
<script type="text/template" id="search_template">
<label>Search</label>
<input type="text" id="search_input" />
<input type="button" id="search_button" value="Search" />
</script>
</body>
</html>

The major issue is the order of your script tags,
<script type="text/template" id="search_template">
<label>Search</label>
<input type="text" id="search_input" />
<input type="button" id="search_button" value="Search" />
</script>
does not exist when your script runs. You should make sure it does, By adding it before the one containing code, or wrapping your code in $(function(){}) etc.
Another issue is that you should use this.$el.html(template); instead of this.el.html(template);

Fix the typo:

ng-click doesn't invoke method inside angularJs controller

I am trying to create an angular application from scratch. I have been trying to solve this for hours now, but I couldn't make it work.
All the following files are placed inside a parent folder.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Hello</title>
<script data-require="angular.js#1.6.0" data-semver="1.6.0" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-app="app">
<h1>Student App</h1>
<section ng-controller="HelloController">
<h4>Enter Student Details</h4>
<label for="name">Name :</label>
<input id="name" type="text" ng-model="student.name" />
<p>Hello {{student.name}}!</p>
</section>
<button id="name" type="submit" ng-click="onButtonClick()">Click</button>
</body>
</html>
HelloController.js
angular.module('app', [])
.controller('HelloController', ["$scope", function($scope) {
$scope.onButtonClick = function()
{
console.log("method invoked");
};
}]);
It would be nice if someone could help me solve this problem I am facing.
Your button is out of the <section> controlled by the controller. So clicking on it calls onButtonClick() on the root scope, not on te controller's scope.

angular uib-popover-template input two-way binding

I am working on uib-popover recently, I found a problem that I am confused with.
I want to popover a template, in this template I have an input, at first the input have initial value.
I want to update the content real-time based on the input. When I just bind a variable, it does not work, while if I bind an object, it works. I can't figure this problem out.
index.html

<button uib-popover-template="'myPopoverTemplate.html'" popover-placement="bottom-left" type="button" class="btn btn-default">Popover With Template</button>

example.js
angular.module('ui.bootstrap.demo', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('PopoverDemoCtrl', function($scope, $sce) {
$scope.dynamicPopover = {
title: 'Title'
};
$scope.inputContent = "hello";
});
Here is the plunker example https://plnkr.co/edit/IPXb5tddEPQPPAUrjdYx?p=preview, you could have a try.
You made an interesting point in your second plunk. I didn't catch this the first time but I think it may be because you are doing your popover input in a script tag. I would suggest using a custom directive if you could versus just doing it in an inline script. That way it is kept up to date with angular's digest cycle.
Example Directive:
customPopoverApp.directive('customPopover',['$compile','$templateCache',function($compile,$templateCache){
return {
restrict:'A',
transclude:true,
template:"<span>Click on me to show the popover</span>",
link:function(scope,element,attr){
var contentHtml = $templateCache.get("customPopover.html");
contentHtml=$compile(contentHtml)(scope);
$(element).popover({
trigger:'click',
html:true,
content:contentHtml,
placement:attr.popoverPlace
});
}
};
}]);
And to use it:
<button custom-popover="" popover-place="bottom">click on me to show the popover</button>
{{message}}
<script type="text/ng-template" id="customPopover.html">
<div class="form-group">
<input type="text" ng-model="message" class="form-control">
</div>
</script>
Here is a working plunk. I hope this is what you're looking for

Angularjs button click $mdDialog not working

<div ng-controller="myController">

This is my content page.
var myApp = angular

$scope.searchclick=function(){
$mdDialog.show({
template:'searchold.html'
});
};
});
This is my js file.
I also have 2 html files namely "addnew.html" and "searchold.html". Not getting pop up of those two files on button click. Is there an error in my code? Kindly help me..
Your dependent module name is wrong. Instead of $mdDialog it should be ngMaterial. $mdDialog is the service being injected in controller and is part of the ngMaterial module. Change your code as below to get it working:
var myApp = angular
.module("myModule",['ngMaterial'])
.controller("myController",function ($mdDialog,$scope){
$scope.addclick=function(){
$mdDialog.show({
template:'addnew.html'
});
};
$scope.searchclick=function(){
$mdDialog.show({
template:'searchold.html'
});
};
});

Broken bindings when using modal dialog in angular

I am using the ngModal modal dialog box directive for my angular application. It's displaying some weird behavior that I don't quite understand. When I attach variables directly to the controller's $scope and reference them in the dialog box, the binding breaks. Changing their values in the dialog has no effect on the variables in the controller. But if I add the variables as properties to an object and then add the object to the $scope it works. In other words, if I do this
$scope.v1 = 1
$scope.v2 = 'abc'
it doesn't work, but if I do
$scope.myData = {
v1: 1,
v2: 'abc'
}
things work fine. What's the deal? You can see a working version of the code here and a broken version here.
If the plunk apps aren't loading for you, here is the code:
