[jQuery] Re: Question about variable declaration

[Nicola Rizzo]

$('.left_selected') returns always true, because if there's not a
matching element, $('.left_selected') is an array (not null) with
length = 0.

[jQuery] Re: How to check if the browser supports iframes?

[Nicola Rizzo]

Try something like:



function test(){
var ghh = document.createElement("iframe");
ghh.style.display = "none";
var frms = document.frames || window.frames;
var len0 = frms.length; 
document.body.appendChild(ghh);
var len1 = frms.length; 
var supported = (len0 != len1);
window.alert("supported: " + supported);
}

[jQuery] Re: processing json object

[Nicola Rizzo]

success: function(json, status){
var records = json.Records;
var str = "";
if(records){
for(var i = 0; i < records; records++){
for(var j in records[i]){
str += j + " --> " + records[i][j] + "\n";
}
}
window.alert(str);
}
}
