The universal loade xls files
steps:
load xls file
set select value according to col data and again load
Why , on second step function changeSelect return undefined, or how on second step get value all select's user-selected!?

Short answer: You are asking for $scope.myOpt from a scope that is an ancestor of the scope that actually contains myOpt.
Long answer: This code:
<body ng-controller="MainCtrl">
...
<tr ng-repeat="row in rows">
<td ng-repeat="cell in row">
<select ng-change="changeSelect();" ng-model="myOpt" ng-options="..."></select>
Creates the following scope hierarchy:
$rootScope
MainCtrl scope <- myOpt is read here
1st ng-repeat scope
2nd ng-repeat scope <- myOpt is set here
According to JS prototypical inheritance, the ancestor scope cannot see the variable.
For your case I'd suggest passing myOpt to the changeSelect():
<select ng-change="changeSelect(myOpt)" ng-model="myOpt" ng-options="..."></select>
And:
$scope.changeSelect = function(x) {
console.log(x); // or whatever
};

You can pass the value into your function, like so:
$scope.weatherUpdate = function(cityName) {
And change the HTML file, like so:
<li ng-click="weatherUpdate(x.cityName)" ng-repeat="x in cities">
This way, you can use the cityName variable within your weatherUpdate function
you should pass 'x.cityName' instead of 'cityName' in to the ng-click function.
<li ng-click="weatherUpdate(x.cityName)" ng-repeat="x in cities">
<span ng-model="cityName">{{x.cityName}}</span>
</li>
Here is you code updated.
I have passed cityName to function and assigned it to name variable you want to show.
Also I fixed part of code where you calling weather api to use selected city in query.
Hope it help.

[object Object] is automatically appeared as value in every textbox in my form. May i know what went wrong? It appears after i inserted the attribute name="searchr" in tag. Thanks.
in search.htm:
<form ng-submit="search()" ng-controller="formcontrol" name="searchr">
<input type="search" placeholder="Search here" id="text_search" ng-model="searchr.text" name="text">
in controller.js:
.controller('SearchCtrl', function($scope, $http) { }
<form name="searchr">
This creates an object of type FormController, and stores it into the scope under the name searchr.
<input name="text">
This creates an object of type NgModelController and stores it in the FormController's text attribute.
<input ng-model="searchr.text">
This tells angular that the model of the field (i.e. the text that must be displayed in the field) is searchr.text, but due to the above, searchr.textis the NgModelController object created by angular, which is part of the FormController object created by angular.
Don't use the same name for the form as the name you use to store the model of the form.

Below I have function called setProject() inside this function I have to send Id but value is not binding.
<tr ng-repeat="Project in Projects">
<td>
<div>
<input type="radio" ng-click="setProject({{Project.Id}})"/> {{Project.Nm}}
</div>
</td>
</tr>
When using ng-click you don't need to interpolate { }:
Change this:
ng-click="setProject({{Project.Id}})"
To this:
ng-click="setProject(Project.Id)"
The ng-click directive is already away of the Angular context in this case. It takes an Angular Expression as input.

I have an array like var names=["price","quality","service"], I have to convert that array to object like names=[{"name":"price", "value":"1.3"},{"name":"quality","value":"3"},{"name":"service","value":"3.4"}]. Each and every time array values are different. I need to do build the input field with that values by using ng-repeat like
<div ng-repeat="n in names">
<input name="rating" ng-model="n" value="0"/>
</div>
How I can fetch the values as objects when user submits the form. can any one help me.
Update
I need json as like this:::
names=[{"name":"price", "value":"1.3"},{"name":"quality","value":"3"},{"name":"service","value":"3.4"}]
ThanQ!
Declare you model object
$scope.item={};
Then just do
<div ng-repeat="n in names">
<input name="rating" ng-model="item[n]" value="0"/>
</div>
The data will be collected into item object.
Update: To get such in such a model, we would have to create it before binding it to view. Assuming names has all the items in the controller do:
var items=names.map(function(name){ return { name:name,value:null}; })
This creates an array of the format you require.
Now bind the view to:
<div ng-repeat="item in items">
<input name="rating" ng-model="item.value" value="0"/>
</div>

I have the following code
<tbody ng:repeat="i in data">
<tr>
<td>{{i.Dia}}</td><td>{{i.TMed}}</td>
</tr>
</tbody>
Is it possible to use a variable instead of "TMed" like "api_method"?
<td>{{i.Dia}}</td><td>{{i.api_method}}</td>
Thank you very much

This should solve your problem:

If you access the key of a JavaScript object with array syntax, you can use variables:
<td>{{ i[api_method] }}</td>
You can define data and api_method anywhere, for example in MainCtrl:
app.controller('MainCtrl', function($scope) {
$scope.api_method = 'TMed';
$scope.data = [
{ "Dia": "2011-11-01", "TMed": "0.0" }
// more data...
];
});
