# Aider chat conversation:
USER: check to make sure there is a mdurl param, skip the rest if not
ASSISTANT: To implement this change, we need to modify the `share/index.md` file. We will add a condition to check if the `mdurl` parameter exists before proceeding with the rest of the script.
Here is the proposed change:
```markdown
share/index.md
<<<<<<< ORIGINAL
window.onload = function() {
var urlParams = new URLSearchParams(window.location.search);
var conv = urlParams.get('mdurl');
fetch(conv)
=======
window.onload = function() {
var urlParams = new URLSearchParams(window.location.search);
var conv = urlParams.get('mdurl');
if (!conv) {
return;
}
fetch(conv)
>>>>>>> UPDATED
```
This change checks if `conv` (which holds the value of the `mdurl` parameter) is not present. If it's not, the function returns immediately, skipping the rest of the script.
# Aider chat conversation:
USER: also load https://cdn.jsdelivr.net/npm/marked/marked.min.js
ASSISTANT: To load the `marked.min.js` library from the CDN, we need to add a script tag in the `index.md` file. Here is the change:
```markdown
share/index.md
<<<<<<< ORIGINAL
<script>
window.onload = function() {
=======
<script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>
<script>
window.onload = function() {
>>>>>>> UPDATED
```
This change adds a new script tag before the existing script tag. The new script tag loads the `marked.min.js` library from the CDN. The existing script tag remains unchanged.
