AngularJS复制现有表行

Question

I have a table with an edit and delete button. But now I also want to make a clone button.

The clone button should work as follows: It clones almost all the data (data such as the id he cannot take) from the row that the user has clicked. Then it goes to the edit page and there it fills the data in the input/select values.

But I have no idea how I get this done. I have now a function which output all the data: var cloneJob = angular.extend(job);

Then it goes to the edit page location.href = '#/jobs/add'; But the problem is that he doesn't fill the input/select values. Does AngularJS has a function for this? And am I on the right track or do I need to do something else?

UPDATE Here is a litle bit more code:

This is my the code of my table:

<tr ng-repeat="job in (filtered.rows = (jobs | orderBy: orderByDate:true | filter:filterByActive | filter:filter.query)) | skip:pagination.pageSkip() |limitTo:pagination.perPage" ng-class="{ inactive : !job.active }"  style="cursor: pointer;">
    <td>
        <span ng-bind="job.title"></span>
    </td>
    <td>
        <span ng-bind="job.client.name"></span>
    </td>
    <td> 
        <span ng-bind="job.referenceNumber"><span>
    </td>
    <td> 
        <span ng-bind="job.creationDate"><span>
    </td>
    <td>
        <a ng-href="#/jobs/edit/{{job.id}}/tab/candidates" ng-bind="job.candidates.length"></a>
    </td>
    <td>
        <span class="status" ng-class="job.status.value"></span>
    </td>
    <td>
        <a ng-if="job.active" ng-href="#/jobs/edit/{{job.id}}" class="icon go">
            <span class="tooltip" translate="job_name_details"></span>
        </a>
        <a ng-if="job.active" class="icon close" ng-click="showClosePopup(job)">
            <span class="tooltip" translate="job_close"></span>
        </a>

        <a ng-click="cloneJob(job)" ><span>Clone!</span></a>
        <!-- <button data-ng-click="cloneItem(food)" class="btn inline">Add</button> -->

    </td>
</tr>

Function cloneJob is:

$scope.cloneJob = function (job){
    var cloneJob = angular.extend(job);
    location.href = '#/jobs/add';
}

This outputs a lot of json (all the correct data) and it goes to the add page.

Answer 1

Try something like

<tr ng-repeat="whatever in whatevers"><button ng-click="duplicateItem(whatever)">duplicate</button></tr>

And on the controller:

$scope.duplicateItem = function(item){
   $scope.duplicatedItem = angular.copy(item); //this will do a copy, not just assign a reference.
   //if you need clean the duplicate item
   delete $scope.somePropertyYouWannaClean;
}

It would better if you provided a working example fiddle or at least more code, so we can give you more accurate answers.

Edit:

A cleaner way would be to make the clone function load the info into a service (or factory , a singleton ). Then after loading the route you use that service to get the content back and play with it.

Like:

angular.module('some.namespace.factory', [])
    .factory('CloneJobFactory', function () {
        return {
            job: null,
            loadJob: function (job) {
                var auxJob = angular.copy(job);//if you just need a shallow copy use angular.extend
                this.job =  this.cleanJob(auxJob);
            },
            getClonedJob: function(){
                return this.job;
            },
            cleanJob: function(job) {
                //code that cleans a job object that has been cloned
                delete job.propertyYouDoNotWantToKeep;

                return job;//return the cleaned job
            }
        };
    });

Then the clone function that would be in the controller (that now has to inject the factory we just made) just has to wrap the loadJob method:

$scope.cloneJob = function (job) {
    CloneJobFactory.loadJob(job);
}

The same for the function that would use the cloned data:

$scope.someFunction = function (whateverParams) {
  var clonedJob = CloneJobFactory.getClonedJob();
  //whatever you want
}

This can still be improved.

NOTE : Angular singletons are made to, among other things, share info between controllers, services and so on.

Answer 2

Make a new 'clone' route, that uses the same controller and view as your 'add' route, but passes in the id of the job that should be cloned:

.when('/jobs/add', { templateUrl: 'jobs/add', controller: 'AddController' })
.when('/jobs/clone/:id', { templateUrl: 'jobs/add', controller: 'AddController' })

Then, in the AddController, check if an id has been passed using $routeParams. If there is an id, fetch the job with the id, and initialize the model by cloning the job. If there's no id, initialize the model with an 'empty' job.

myModule.controller('AddController', function($scope, $routeParams){
    if($routeParams.id) {
        //TODO get existing job using $routeParams.id
        $scope.newJob = angular.copy(job);
    } else {
        $scope.newJob = {};
    }
});
