noob IE javascript question: "Object dosen’t support this property or method"

Copy linkTweet thisAlerts:

var topicText = document.createElement(“span”);
topicText.setAttribute(‘class’, ‘current’);

[COLOR=”Red”]topicText.appendChild(document.createTextNode(String.concat(‘ – ‘, lastText)));[/COLOR]

so… this works in Firefox… why do i get this in IE???? (the red text is the line which IE complains about)

? ?

@gil_davisFeb 04.2008 — Apparently IE's JScript "concat()" function is not the same as FF's. ?

Just use the "+" sign and be done with both browsers:
<i>
</i>topicText.appendChild(document.createTextNode(" - " + lastText));

@ZeroKilledFeb 04.2008 — you should never call a method within a class object unless that method is static, e.g. the method [B]fromCharCode[/B]. however, if you want to call a method that isn't static within the object, most probably you should use the [B]prototype[/B] object:

String.prototype.concat(...)
