angularjs to output plain text instead of html

Question

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>

Answer 1

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>  

Answer 2

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>

Answer 3

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.

Answer 5

<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 eg var app = angular.module("myApp", ['ngSanitize']);

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

Answer 6

您可以使用ng-bind-html，不要忘记将$ sanitize服务注入您的模块希望它有所帮助

Answer 7

使用ng-bind-html这只是最恰当和最简单的方法

Answer 8

Use this function like

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

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