AngularJS/JavaScript - 如何重命名数组键名

Question

I have an application that reads an excel file, and displays its contents in an html table.

These elements are in an array called "AgendaItems".

There are 2 files the user can read, each is formatted with some differences. Both have 3 columns.

File 1: AgendaItem, LegistarId, Title File 2: Agenda #, File #, Title

I am able to read the file and populate the array $scope.AgendaItens with the contents of either file, depending what the user selects.

My problem is that before making these modifications to accept a second file with a different format, I used:

<td scope="row">{{ai.AgendaItem}}</td>
<td>{{ai.LegistarID}}</td>

When processing the new file, now the array contains: Agenda #, and File #, which are equivalent to AgendaItem, and LegistarID respectively.

Is there a way to, in the HTML choose which value to display? for example, if array has AgendaItem, display AgendaItem, if array has Agenda #, display Agenda #?

Or, is it possible to rename a the name of a key, from Agenda # to AgendaItem and from File # to LegistarID?

Please let me know if I need to post more details, more code in order for me to be able to get help.

Thank you in advance, Erasmo

Answer 1

You can use javascript array.map extension? May be better for later reading the code.

Source data

var source = [{"Agenda #":"1","File #":"file1.xls"}]

Map it for cleaner usage

var maped = source.map(function(p) {
    return {"AgendaItem":p["Agenda #"], "LegistarID":p["File #"]}
})

Other wise you have to use Object[fieldName] usage in html.(not suggesting to do so) like; ng-if="expression"

  < ... ng-if='data["Agenda #"]' > {{data["Agenda #"]}}
