问题
I have tasks listed and each task has both a "Do" button and a "Fund" button. Once I click on the "Do" button or "fund" button, I want the specific task to be assigned to a state of "DoRequested" or "FundingProposed". I just do not know how to add these states to the specific model in my case.
As I am new to angular, I have no idea on how to do this.
Here is my view code so far:
<div ng-app="facebookExample" view-title="Tasks">
<div ng-controller="todoController">
<h1>Tasks</h1>
<div class="item item-input-inset">
<label class="item-input-wrapper">
<!-- The actual input tag which is bound to the todoInput using ng-model -->
<input type="text" placeholder="Add New Item" ng-model="todoInput" size="100">
</label>
<!-- Our button thay will call our funtion to add a new todo item -->
<button class="button button-small" ng-click="todoAdd()">
Add Task
</button>
</div>
<div ng-repeat="x in todoList">
<li class="item item-checkbox">
<label class="checkbox">
</label>
<!-- this is the checkbox element, you will see it is bound to the done setting in the items array -->
<!-- When clicked it calls the update function to update the item to its done status -->
<input type="checkbox" ng-model="x.done" ng-click="update()"/>
<!-- this is a span tag that shows the item text, I am using ng-bind, instead of the span tag we could have used {{x.todoText}} as well -->
<button class="fund-button" style= "float: left;" ng-click="fund(x)">Fund</button>
<span>{{x.todoText}}</span>
<button class="doButton" style= "float: right; margin-right: 2px;" ng-click="do(x)">Do</button>
</li>
</div>
<!-- the remove button will call the remove function and remoave all items that are marked done -->
<button class="button button-block button-assertive" ng-click="remove()">Remove Checked Tasks
</button>
</div>
</div>
And my controller:
facebookExample.controller('todoController', ['$scope', function($scope) {
// Initialize the todo list array
//if local storage is null save the todolist to local storage
$scope.todoList = [];
if (localStorage.getItem("mytodos") === null)
{
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
}else
{
//set the todolist from local storage
$scope.todoList = angular.fromJson(localStorage.getItem("mytodos"));
}
// Add an item function
$scope.todoAdd = function() {
//check to see if text has been entered, if not exit
if ($scope.todoInput === null || $scope.todoInput === ''){return;}
//if there is text add it to the array
$scope.todoList.push({todoText:$scope.todoInput, done:false});
//clear the textbox
$scope.todoInput = "";
//resave the list to localstorage
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
};
// Each task is limited to limit total funding = $1000
//current funding ; max funding; ballance funding = $1000-current
// Variables or columns for taskX
/****************/
// Task Counter for Task X
// If task-assignment is aproved by admin

//Do button
$scope.do = function(){

};
$scope.doForFree = function(){
// Task is assigned to user with a state of pending-aproval-of-admin- assignment-do-for-free
// Admin is notified of do-for-free-request
};
// if admin aproves user that requested to do task X for money

//fund button
$scope.fund = function(){
//Redirect current user to paypal for payment to You-Serve
// Maximum payment cannot exceed Maximum amount - what 's already funded
// Need to keep track of already funded amount
// Need to keep track of task cost/price
// If paypal payment was done successfully
// Update already funded amount
// Update maximum amount for extra funding
// update the fully funded variable/boolean
// Send task/user/amount to database
// If payment fails, take out state of being funded
};
$scope.remove = function() {
//copy list
var oldList = $scope.todoList;
//clear list
$scope.todoList = [];
//cycle through list
angular.forEach(oldList, function(x) {
//add any non-done items to todo list
if (!x.done) $scope.todoList.push(x);
});
//update local storage
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
};
//The Update function
//This waits 100ms to store the data in local storage
$scope.update = function() {
//update local storage 100 ms after the checkbox is clicked to allow it to process
setTimeout(function(){
localStorage.setItem("mytodos", angular.toJson($scope.todoList));
},100);
};
}]);
回答1:
So from a quick read through your code it seems what you want is to process the specific item by ng-click="do(x)" and add it to "DoRequested" or "FundingProposed"
So the simplest way would be to pass the item via ng-click which you did correctly. So modify the script to something like this :
$scope.DoRequested = [];
$scope.fund=function(x){
.
.
.
$scope.DoRequested.push(x);
console.log($scope.DoRequested);
}
now each time you click the fund button , x is added to array.
Here's a fiddle
