Question

How can I add a param to the removeSound function in this JavaScript code?

I cannot get it to work.

var param = "111";

coder = '<a href="javascript:;" onClick="javascript: removeSound(' + param + ');" >Delete</a>'

Update

I do not know why code = was removed! This is needed to explain the problem context.

Answer 1

I just want to add a proper double quoting escape method to the answers as none showed a correct way to escape double quotes inside of an onClick attribute.

In HTML it is not sufficient to use only a backslash when escaping a JavaScript double quote. You need the proper HTML entity which is "

This is a live example:

<a href="#" onClick="removeSound(&quot;121212&quot;);">Delete</a>

However for readability I would recommend using Antony Scott’s way by using single quotes.

<a href="#" onClick="removeSound('121212');">Delete</a>

To add the param as a variable from whatever script your HTML is generated in you should do this:

code = '<a href="javascript:;" onClick="javascript: removeSound(&quot;' + the_param + '&quot;);" >Delete</a>';

The other possible way should be:

code = '<a href="javascript:;" onClick="javascript: removeSound(\'' + the_param + '\');" >Delete</a>';
