javascript += operator

Question

In my JSON javascript live pull I have:

    html += "<tr><td width=60 valign=top><a href='"+item.url+"' target='_blank'>"+item.site+"</a></td>";

The += seems to strip out my tr td values So I tried amending it to = which just seems to fail.. I tried setting td as a var and still no luck

Any ideas of a way round this, my js is basic so even if you think its silly your answer could help me greatly..

EDIT

to confuse things things further the = alone works in Firefox but on IE the items are loading hidden in the background.. I don't get why the browsers would perform so differently over the use of one + sign...

How are you trying to use this html value? How do you know those things are being stripped? — Chris Farmer

You should show us some more of your code. What is the value of html before the line you include? What are you doing with it after setting/appending to it? — Daniel Vandersluis

EDIT They are displayed table less in the browser.. and viewing the output both tag are missing — Webby

When you say "output" do you mean the html source? Or do you mean the rendered content in the browser? — Chris Farmer

try:

html += "<tr><td width=60 valign=top><a href='"+item.url+"' target='_blank'>"+item.site+"</a></td></tr>";

Your markup generated is invalid (not closing the anchor tag) so it's possible the browser isn't interpreting the html very well.

that was just a mistake when rewriting it here haha

You should update your question then as it's misleading. I hope you didn't downvote because of that fact as someone did. You should also consider posting more code than one line as the line in question may not even be the issue at all.

x += y is just a shorthand for x = x + y. If you change it to html = "...", you'd be overwriting anything that already existed in the html variable.

How are your "tr td values" being stripped?
