Question

function OpenWindow(anchor) {
        var toUsername = anchor.innerText;
        window.open("ChatWindow.aspx?username=" + toUsername,'_blank', "width=340,height=200");       
    }

this function opens up a page with parameter as undefined in firefox where as in google chrome I get proper value.

Firefox url:
http://localhost:9452/ChatWindow.aspx?username=undefined

What is the solution for this issue?

Answer 1

While innerText is non-standard, it significantly differs from textContent, because first one is doing pretty printing (for example, <br/> are converted to new lines), while second one – is not.

So, while common wisdom is to use:

var toUsername = anchor.innerText || anchor.textContent;

or some kind of wrapper, it can probably be smarter to just use jQuery’s .text or its analog from other library you are using.
