这段代码:
var doc = {
foldPrompt: function(folded) {
return folded ? "Click to unfold" : "Click to fold"
},
createFoldButtons: function() {
var prompt = foldPrompt(true); //The error is here
$("#ComparisonTable td.secrow").each(function(index, td){
$(td).prepend($('<img src="minus.gif" class="foldbtn" alt="'+prompt+'" title="'+prompt+'">'));
});
}
}
给我一个错误:Undefined variable: foldPrompt
我究竟做错了什么?
