I have some text like this:

<span>My text</span>

I want to display without tags:

My text

I also don't want to apply the tags, I want to strip them. What's an easy way to do that?

Angular html:

<div>{{myText | htmlToPlaintext}}</div>

You have tagged this under AngularJS, so I assume you want to do display the text using AngularJS. If so, is this text in a model? Which html tag are you using to display the contents of the model? - callmekatootie
@callmekatootie I created a filter based on the answer Abhishek gave. - Harry
I see that and his solution uses jQuery - You have tagged this under AngularJS and I have a feeling that you you can do it in AngularJS without using jQuery, if only you can give more information in your question - particularly where you wish to display the text in your view... - callmekatootie
@callmekatootie I added an example of what I'm doing in angular - Harry

jQuery is about 40 times SLOWER, please do not use jQuery for that simple task.

function htmlToPlaintext(text) {
  return text ? String(text).replace(/<[^>]+>/gm, '') : '';
}

usage :

var plain_text = htmlToPlaintext( your_html );

With angular.js :

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
  }
);

use :

<div>{{myText | htmlToPlaintext}}</div>

from https://docs.angularjs.org/api/ng/function/angular.element

angular.element

wraps a raw DOM element or HTML string as a jQuery element (If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.")

So you simply could do:

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return angular.element(text).text();
    }
  }
);

Usage:

<div>{{myText | htmlToPlaintext}}</div>

var app = angular.module('myapp', []);

app.filter('htmlToPlaintext', function()
{
    return function(text)
    {
        return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
});

You want to use the built-in browser HTML strip for that instead of applying yourself a regexp. It is more secure since the ever green browser does the work for you.

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return stripHtml(text);
    };
  }
);

var stripHtml = (function () {
  var tmpEl = $document[0].createElement("DIV");
  function strip(html) {
    if (!html) {
      return "";
    }
    tmpEl.innerHTML = html;
    return tmpEl.textContent || tmpEl.innerText || "";
  }
  return strip;
}());

The reason for wrapping it in an self-executing function is for reusing the element creation.

<div ng-bind-html="myText"></div> No need to put into html {{}} interpolation tags like you did {{myText}}.

and don't forget to use ngSanitize in module like e.g. var app = angular.module("myApp", ['ngSanitize']);

and add its cdn dependency in index.html page https://cdnjs.com/libraries/angular-sanitize

You can use ng-bind-html, don't forget to inject $sanitize service into your module Hope it helps

Use this function like

 String.prototype.text=function(){
   return this ? String(this).replace(/<[^>]+>/gm, '') : '';
 }

  "<span>My text</span>".text()
  output:
  My text
