Service Portal: ng-repeat not working

[Vinay Krishna1]

Hi all,

I'm trying to create a very basic widget where the input field takes value and updates the DATA object every time the function is clicked. And then I display it using ng-repeat int he HTML view. But I ran across into an issue where ng-repeat is not showing the list of all items I entered, instead only showing the last one. Please look into the issue. 

HTML: 

<ul><li ng-repeat='x in c.data.items'>{{x}}</li></ul>

<input type='text' ng-model='c.data.message'/>
<button ng-click='c.additem()'>Add</button>

Client script:

function($scope) {
var c = this;

c.additem=function(){

c.server.update().then(function(response){
c.data.message='';
});
}}

Server script: 

(function() {
data.items=[];
if(input)
{
data.items.push(input.message);
}

})();

I've tried uisng c.server.get() as well like the below one. It's still not working. 

c.server.get({additem:c.data.message}).then(function(response){

c.data.message='';

c.data.items=response.data.items;});

Server:

if(input.additem)

data.items.push(input.additem);

Hello Vinay,

Well, looking at your code, ng-repeat goes good with table tag.

Please look to the similar code that displays all the items,

HTML :

<table class="table table-bordered">
<thead>
<tr>
<th>Message</th>
</tr>
</thead>
<tbody>
<tr >

<td><input type='text' ng-model="c.data.message"></td>

</tr>
<tr ng-repeat="m in c.data.dataFromFields track by $index">
<td>{{m.message}}</td>

</tr>
</tbody>
</table>
<button type="button" ng-click="c.add()" class="btn btn-warning">Add</button>

CLIENT SCRIPT: 

function($scope) {
/* widget controller */
var c = this;

c.add = function(){
c.data.action = "add";
c.server.update().then(function(){

c.data.action=undefined;

//Clear the Boxes.
c.data.message = "";

});

}
}

SERVER SCRIPT:

(function() {

data.dataFromFields = [];
if(input){
data.dataFromFields = input.dataFromFields;

}
if(input.action=="add"){

var dataArray={};
dataArray.message = input.message;
data.dataFromFields.push(dataArray)
data.dataFromFields.forEach(function(item){
gs.addInfoMessage(item)
})

}

})();

I'll try to simply the code more if you want.

Please mark helpful if that served your requirement.

Regards,

Kush

I've found a way to make it work. You just need to add this line in the server script. What it does is it stores the previous value of data.items through input.items. 

data.items=[];

if(input)

{

data.items=input.items;
data.items.push(input.message);
}
