Only allow certain tags in contenteditable div












0














I have a contenteditable div and using keyboard shortcuts like ctrl+i the user is able to format the text. And as they type the innerHTML changes reflecting the tags i.e:



Hello&nbsp;<i>thanks for&nbsp;<br><br>for showing up<b>&nbsp;y'all b</b></i>



This is fine, and works well for my purposes. but the issue arises that when I go to print the html in a different div IF a user adds any other html tags, they could really mess up the application.



For instance, if they added a <script> tag or style etc.. How do I make it that the user is only allowed to add <i>, <br>, <b>, <s>, and &nbsp; without being able to add anything else?



Any ideas? Thank you

  • I'm not sure it does directly other than allowing you to create a custom editor that allows them to type whatever text they want into the editor, and if they want to add emphasis, italics, bold, etc. you provide them a user interface to control that. The only other option is to parse the string and eliminate any thing that looks like a tag you don't want. That is inexact and may or may not achieve quality results for you.

I think that you can use a regExpresion to avoid the "indeseables" tags. Some like



<textarea #data [(ngModel)]="value" (input)="replace(data)"></textarea>
<div [innerHtml]="valueParse">
</div>

replace(control:any)
{
this.valueParse=control.value.replace(/<(?!br|i|u)((w+))>/gm,"&lt$1&gt")
.replace(/</(?!br|i|u)((w+))>/gm,'&lt/$1&gt');
}
