I am trying a very basic javascript map example
var map1 = {'myKey1':11, 'mykey2':22};
var t = map1['mykey1'];
alert(t);
But the alert always gives me 'undefined', it should give me '11'
please guide what i am doing wrong
You have a spelling mistake there mate, notice that in your map1 object there is no mykey1 key actually, there is a myKey1 key however, containing a capital K

I'm trying to find a way to output an array in alphabetical order as well as the length by a window alert, or alternatively any way for the user to be able to see it, when they're in the browser.
Here is the little bit of code:-
var vehicles = ["Car", "Bus", "Train", "Boat","Plane"];
vehicles.sort();
As well as:-
vehicles.length();
It is vehicles.length not vehicles.length()
You can output in an alert
alert( vehicles.length );
or log into the console
console.log( vehicles.length );

i am trying to check what items are in array.
this is my code
var fruits=['banana','orange','lemon'];
fruits.splice(0,1,'apple');
for (i=0;i<=fruit.length;i++)
{
alert('The fruits are' + fruits[i]);
};
Somehow it's not Working.
please tell me where i am doing wrong.
thanks.
Have you mistakenly added fruit.length or you have written code like this?
syntax;-
array.splice(index,howmany,item1,.....,itemX)
index->positon from/to u want to ad and remove items
howmany->how many item u want add/remove
item->item list(for more than pne seprate it by comma)
also:-
please add s after fruit in for loop

I can not figure out why I can't access the result elements.
Whats getting returned:
[{"customSurfaceMaster": {"CSMasterID":1,"CSName":"Q17","QuestionId":12,"OpType":"22","OpFlag":null,"ChartType":"Bar"},"UserCSID":1,"UserId":2,"CSMasterID":1,"PeriodType":null,"PeriodStartValue":null,"PeriodEndValue":null,"ImpLevel":1,"DisplayOrder":1,"Visible":true}]
Trying to access here:
var Tile = BindTiles(result.customSurfaceMaster.chartType, result.customSurfaceMaster.CSname, result.ImpLevel);
The error:
result.customSurfaceMaster is undefined
Try this:
var Tile = BindTiles(result.customSurfaceMaster[0].chartType, result.customSurfaceMaster[0].CSname, result.ImpLevel);

$("td[id^='td0_']")
My question is how can I replace 0 in the example above with a variable myvar?
You should be able to use:
$("td[id^='td" + myvar + "_']")
Use the quotes appropriately.
$("td[id^='td" + myvar +"_']")
