angular nl2br filter

angular.filters.nl2br.js

/*

# Usage in html template:

"xxx | nl2br"

<div ng-bind-html=" YourString | nl2br "></div>

or:

"xxx | nl2br:Boolean"

Boolean( true or flase or just keep null) means is xhtml  or not

if is xhtml, replace with <br/> ; if not , replace with <br>

<div ng-bind-html=" YourString | nl2br:true "></div>


-------------------------

# Example:

//==Analog data===
$scope.items = [
    {"message": "test"},
    {"message": "New\nLine"},
]
//=====
<div class="comment" ng-repeat="item in items">
    <p ng-bind-html=" item.message | nl2br "></p>
</div>

-------------------------

# Output result:

<div class="comment ng-scope" ng-repeat="item in items">
    <p class="ng-binding" ng-bind-html=" item.message | nl2br ">
        test
    </p>
</div>
<div class="comment ng-scope" ng-repeat="item in items">
    <p class="ng-binding" ng-bind-html=" item.message | nl2br ">
        New<br>Line
    </p>
</div>

angular.filter('nl2br', function($sce){
    return function(msg,is_xhtml) { 
        var is_xhtml = is_xhtml || true;
        var breakTag = (is_xhtml) ? '<br />' : '<br>';
        var msg = (msg + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1'+ breakTag +'$2');
        return $sce.trustAsHtml(msg);
    }
});

Is there a way to use this without allowing all other HTML too?

$scope.text = "This is <b>nonsafe</b> html\nThis is safe!";

<p ng-bind-html="text | nl2br"></p>

(this also makes the nonsafe tekst bold.. but what if I don't want that?)

Thanks – this does almost exactly what I need 👍
There is only one "mistake" if I could say so: var is_xhtml = is_xhtml || true; There is no way that is_xhtml could be false:

false || true == true
undefined || true == true
'' || true == true

I suggest var is_xhtml = (typeof is_xhtml == 'undefined) ? false : true;

nice one, Thanks
