I am working through Javascript for Kids, which is a surprisingly fun little book for a beginner, but I'm having trouble testing a For Loop example in the text:
var sheepCounted = 0;
for (var sheepCounted = 0; sheepCounted < 10; sheepCounted++) {
console.log(“I have counted” + sheepCounted + “sheep!”);
}
console.log(sheepCounted);
When I use a Javascript tester to test this example I get a syntax error, but I'm not sure why? Can anyone help me out? Thanks.

Change this line which uses “ ”:
console.log(“I have counted” + sheepCounted + “sheep!”);
To this with " ":
console.log("I have counted" + sheepCounted + "sheep!");

This part of javascript code works on my home computer, but doesn't at work. Also, my colleague tested it and it doesn't work on her home computer?!
function klikNaX(x, y, z) {
var u = document.getElementById(z);
var u2;
u2 = u.style.backgroundColor;
document.getElementById("test").innerHTML = (z + " " + u2);
}
The problem seems to be with this part
u.style.backgroundColor;

Its not a problem of style.backgroundColor, instead please check if 'u' is a valid node and not undefined.
And try setting a color to u.style.backgroundColor = 'green'

I am getting error on this. i don't know what happen here.
enter code here
$(".addCategory").on('click',function(){
var value= $(".getvalue").val();
var x = $("input[name="+value+'[]'"]")
$(x).each(function(key,val){
if($(val).val().length<=0)
{
alert ("Please fill all the fileds");
}
});
});

You have problem with quotes
var x = $("input[name='" + value + "[]']")

Problem was with your quotes:
replace with following code
$(".addCategory").on('click',function(){
var value= $(".getvalue").val();
var x = $("input[name='"+value+"[]']") // add proper quotes
$(x).each(function(key,val){
if($(val).val().length<=0)
{
alert ("Please fill all the fileds");
}
});
});

See How it should wrap up
var x = $("input[name='"+value+"[]']")

I am trying to pass a parameter in query string i.e._type=1 but it doesn't pass. It doesn't appear in URL, other values does but not this one. Why ?
SitePaymentReportByBranch = function () {
$('#btnprintSitePaymentByBranch').on('click', function (e) {
e.preventDefault();
if ($("#form1").validationEngine('validate')) {
var _employerID = "";
if ($('#cmbEmployerSitPaymentByParameter :selected').text() == "-Select-") {
alert('Plz Select Employer');
}
var url = '/Reports/frmSitePayment.aspx?_EmployerID=' + $('#cmbEmployerSitPaymentByParameter :selected').val() + '&_Formdate=' + $("#formdate").val() + '&_Todate=' + $("#todate").val() +'_type=1';
commonStartup.openReportWindow(url);
}
});
},

You missed & before _type fix will be '&_type=1'
var url = '/Reports/frmSitePayment.aspx?_EmployerID=' + $('#cmbEmployerSitPaymentByParameter :selected').val() + '&_Formdate=' + $("#formdate").val() + '&_Todate=' + $("#todate").val() +'&_type=1';

Query parameters must be separated with &. You have omitted this for your _type parameter:
'_type=1'
should be;
'&_type=1'

I have the following jquery function. and i am calling it as below mentioned.
function hideSubArea(area, subArea) {
if ($('#cmdArea').val() == area) {
console.log('hide:' + subArea);
//$(":checkbox[value=peoplebulkinsert]").closest("label").hide();
$(":checkbox[value=subArea]").closest("label").hide();
}
}
And calling it as
hideSubArea('<?php echo CustomType::CF_PEOPLE ?>', '<?php echo CustomType::CF_SUB_PEOPLE_BULK_INSERT ?>');
this way its not working.
also this is not.
hideSubArea('people', 'peoplebulkinsert');
but it works when i directly use as
$(":checkbox[value=peoplebulkinsert]").closest("label").hide();
why this happens with jquery ?

subArea is a variable, not a string in this case. It needs to be concatenated. It should be -
$(":checkbox[value='" + subArea + "']")
