jQuery question. Does anyone know why this doesn't work? fiddle

I have multiple scripts (in the example, just one) from which I will pick one and insert its content into a div. Inside those scripts are buttons with classes that I want to attach on-click events. However, they don't work. In the example, if you click "Insert", it will insert the content from the script to the div. Then you can see that clearly the inserted button will not have a click event attached, yet the standard button does. It also doesn't work if you use a hidden div instead of a script tag.

Any help would be greatly appreciated!

Open up the Chrome console when you click it - it shows this:

Uncaught SyntaxError: Unexpected token < .(index):67

The issue is with the apostrophe in "Doesn't"

Remove the apostrophe and it works (or escape it).

edit:: Nvm - still syntax errors

I'm using chrome and don't get any syntax errors. I tried removing the apostrophe, and still no luck.

Your button is between script tags, for starters.

Easiest way of doing this is setting it to display:none at the start and then toggling it in your javascript.

But the syntax error is because your button is inside the script tags. And the button is html, not javascript.

That doesn't matter. Html inserts from script is fine. What does matter, however, is what tofucake pointed out. Button isn't initiated from start, and thus the onclick in its current form won't work.

Generally tho, inserting elements after the fact isn't a good practice to begin with. If possible you want to load everything at start, and show/hide. Obviously doesn't matter much for just a single button, but loading in elements after the fact makes for a slower page and bad user experience.

<script id="MenuOption1" type="text/javascript">
	<button type="button" class="MyButton">Doesn't Work</button>
</script>

I had a div that I wanted to show one of several different things depending on what the user clicks. Initially I thought I could just put each individual thing in a separate script and insert it into the div. But perhaps it would be better to have them all as hidden divs inside the parent div, and just show/hide what I need?

I compared performance of ms, gcc and intel compiled code for a molecular dynamics simulation as part of my bachelor's thesis. The software ran on the lrz cluster in munich. Obviously I wasn't very concerned with other aspects, but for performance, it was a rather clear intel > ms > gcc.

Also intel's performance analysis tools were awesome.
