What is the best way to manage the apostrophe character in user-provided input within vue.js?

I am facing a problem with user-supplied text retrieved from a CMS. The issue arises when the string contains a simple apostrophe ('), causing the entire string to break and throw an error. I am currently searching for a solution to prevent Vue from getting stuck on this problem, but I seem to have reached a dead end. Even though I suspect it might be something obvious that I am missing. Here is the code snippet:

<span v-html="sidebarContent"></span>

<script>
  var app = new Vue({
    el: '#app',
    data: {
      // the content below represents what is outputted by a server-side rendered variable "@Html.Raw(@Model.Element("BodyCopy").Value)"
      sidebarContent: '<p>This is example text of what's being returned.</p>',
    },
  })
</script>

The main issue seems to be the presence of the word "what's," particularly the use of the apostrophe. Users frequently input full sentences where such apostrophes appear quite often, so the data handling should account for this. Any suggestions on how to achieve this?

Moreover, the error message displayed is: "Uncaught SyntaxError: Unexpected identifier"

Answer №1

To ensure accurate string handling, consider enclosing in double quotes or properly escaping the characters.

mainContent: '<p>This is a sample representation of the output.</p>',

Answer №2

Upon further inspection by @georaldc, it became clear that my approach to solving the issue was incorrect. It wasn't a problem with Vue itself, but rather with how I was using razor.

The solution, as it transpired, was to utilize HttpUtility.JavscriptStringEncode on my razor code. Here's the missing data value that needed to be included:

sidebarContent: '@Html.Raw(HttpUtility.JavaScriptStringEncode(Model.Element("BodyCopy").Value))',
