Enhanced jQuery Embed Code validation for user input using a textarea

Currently, I am developing a website that allows users to input embed codes from popular platforms such as Twitter, YouTube, Instagram, Facebook, and so on. The embed code undergoes validation checks and is saved if it meets the criteria.

However, when users try to view or edit the code, some issues arise with validation. For instance, Twitter embed codes may include special characters like &lt; in the post name or text. While the initial input passes validation with these characters, displaying the code back to the user results in the browser rendering < within the textarea. If the user saves the code in this state, our validation function interprets it as the beginning of a tag, causing the validation process to fail.

Potential Solution 1:

To address this issue, we could improve our validation process. The current method involves identifying tags (such as '<') and ensuring each opening tag has a corresponding closing tag. However, there may be more effective or commonly used approaches available:

(function($) {
$.validateEmbedCode = function(code) {
    // Validation logic
    // Implementation details...
};

}

Potential Solution 2:

An alternative approach could involve encoding text containing '<' (e.g.,

textLine.replace(/</g, '&lt;')
) without affecting tags like <blockquote class="...>.

I have been exploring a potential solution using the following code snippet:

Potential Solution 3:

Another suggestion is to display &lt; as &lt; instead of < in the browser or textarea. Our templating system, similar to Mustache, handles this aspect:

However, attempts to implement this concept, such as date.code = '&lt;' combined with

<textarea name="code">{{{code}}}</textarea>
in the template, have not yielded the desired outcome.

Answer №1

After experimenting further, I have found a solution that works for now. However, I am open to suggestions on how to improve the validation of embed code or any alternative approaches.

Once the edit form is submitted (including the textarea), the code is generated using the icanhaz template. After creating the code with the line

widget = ich.editEmbedWidgetTemplate(encoded_data);
, I proceed to encode characters like < to &lt;. Additionally, the character ' needs to be manually encoded using replace.

var embedCode = '';
$( widget.find("textarea[name='code']").val() )
.filter('*')
.each(function(){
    embedCode += this.outerHTML.replace(/'/g, '&#39;');
});
widget.find("textarea[name='code']").val(embedCode);
