I'm new at JavaScript to be patient with me. I'm trying to get this little "game" to work where you drag cards in the drop box, and when you drop the joker card in it says "victory", otherwise it says "betrayal" for the other cards. Everything works great except the part where it says "victory" when you drop the joker. I feel like I have tried everything. The joker card is $(#black_joker)

I believe you are comparing object with string.
ui.draggable should be jQuery object
let card = ui.draggable.attr("id");
compare it with your id or other attribute you wanted to use should work
My goal for this experiment is to have 2 blocks of trials, both which flash 10 words and then the participants have to click yes or no if they saw the word or not (answer yes or no to 20 words). After the 2 blocks I would like the data to be displayed and the experiment to end, although right now the experiment is infinite and displays data after every block. I also need to know how to save the data with a "Save Data" button after presenting both of the blocks data at the end. Any and all help appreciated!
If anyone has any ideas about how to create two blocks, as I have tried to initiate by declaring blocks = 0 at the beginning it would be greatly appreciated!

My goal is to randomly change an image by clicking on a button. I have found a snippet that does that but I wanted to train my skills and work my way through it, this is what I got so far:
When I click the button, with the variable on line 11, nothing happens, but when I put the URL instead of the variable (copied from the console from line 22), it goes to the according picture. I don't get it...
When my "imageCount" is full, I get an error
var imageCount = [];
var image = ["img/01.jpg", "img/02.jpg", "img/03.jpeg", "img/04.jpeg"];
function changeImage() {
var rand = Math.floor(Math.random() * image.length);
var imageNumber = "\"url('" + image[rand] + "')\""
if (imageCount.indexOf(rand) === -1) {
imageCount.push(rand);
document.getElementById("imageWrapper").style.backgroundImage = imageNumber;
} else if (imageCount.length === image.length) {
imageCount = 0;
} else {
changeImage();
}
console.log(imageNumber);
console.log(imageCount.indexOf(rand));
console.log(image[rand]);
console.log(imageCount);
}
<link href="./style/main.css" rel="stylesheet">

</div>
Two things stop your demo code from working:
#imageWrapper has no height, so the image is not displayed (probably only because your page's CSS is missing)
You reset the imageCount variable to 0 instead of []
var imageCount = [];
var image = ["//baconmockup.com/300/199/", "//baconmockup.com/300/200/", "//baconmockup.com/300/201/", "//baconmockup.com/300/202/"];
function changeImage() {
var rand = Math.floor(Math.random() * image.length);
var imageNumber = "url('" + image[rand] + "')"
if (imageCount.indexOf(rand) === -1) {
imageCount.push(rand);
document.getElementById("imageWrapper").style.backgroundImage = imageNumber;
}
else if (imageCount.length === image.length) {
imageCount = [];
}
else {
changeImage();
}
console.log(imageNumber);
console.log(imageCount.indexOf(rand));
console.log(image[rand]);
console.log(imageCount);
}

I am using html5 and javascript .I am reading excel file from java script and showing output..PLease analyze my code first
<input type="button" id="btnSubmit" onclick="readdata(1, 2)" value="Submit" />
var xVal = 1;
var yVal = 2
function readdata(x,y) {
x = xVal;
y = yVal;
try {
var excel = new ActiveXObject("Excel.Application");
excel.Visible = false;
var excel_file = excel.Workbooks.Open("D:\\Test.xls");// alert(excel_file.worksheets.count);
var excel_sheet = excel_file.Worksheets("Sheet1");
var data = excel_sheet.Cells(x, y).Value;
//alert(data);
drawWithexcelValue(data);
xVal = xVal + 1;
}
catch (ex) {
alert(ex);
}
Now I'm reading the file from this code and showing the output with this code:
function drawWithexcelValue(val) {
var txtSpeed = val; //alert(txtSpeed.value);
if (txtSpeed !== null) {
iTargetSpeed = txtSpeed;
// Sanity checks
if (isNaN(iTargetSpeed)) {
iTargetSpeed = 0;
} else if (iTargetSpeed < 0) {
iTargetSpeed = 0;
} else if (iTargetSpeed > 80) {
iTargetSpeed = 80;
}
job = setTimeout("draw()", 5);
}
}
Q .1 every time i click on the submit button it show me the value from excel file ,i want that i didn't have to click every time on submit button ..it automatically show the values at some time interval for say 4 seconds.

Guys if you can give me edited code than it really will be help full for me

Associated HTML:
<img id="myimage1" src="http://www.hdwallpapers.in/walls/apple_sky_blue_aurora-wide.jpg" width="400" />
<img id="myimage2" src="http://www.hdwallpapers.in/walls/apple_sky_blue_aurora-wide.jpg" width="400" />
<img id="myimage3" src="http://www.hdwallpapers.in/walls/apple_sky_blue_aurora-wide.jpg" width="400" />
<img id="myimage4" src="http://www.hdwallpapers.in/walls/apple_sky_blue_aurora-wide.jpg" width="400" />
This code is meant to show four images, and every 10 seconds, switch all four images simultaneously, going through all of my images in my four arrays. The images are in the images/ directory above my HTML file that contains this code. For testing purposes, I changed myimage1 to change to op.jpg only. This works and correctly shows op.jpg. However, when querying the arrays, instead of the file names, I get undefined. That is problem number one.
Problem number two, when I change my for loop to a more normal looking one like:
for(var i = 0; i < l2; i++)
The script stops working entirely (doesn't show op.jpg and doesn't even try to change the images)... what the hell!
I'm using Firefox and Google Chrome for testing purposes.
I suggest something like that instead:
<script type=text/javascript>
$(document).ready(function () {
var topLeftImages = ["op.jpg", "qa.jpg", "fl.jpg", "eatgr.jpg", "na.jpg", "ctcc.jpg", "na.jpg", "oacahu.jpg", "hc.jpg", "sup.jpg", "oa.jpg", "rffcc.jpg"];
var topRightImages = ["eatgr.jpg", "ulandscaping.jpg", "fp.jpg", "clf.jpg", "lss.jpg", "sup.jpg", "ulandlord.jpg", "lqbc.jpg", "lss.jpg", "lp.jpg", "ulandlord.jpg", "qa.jpg"];
var bottomLeftImages = ["poss.jpg", "un.jpg", "pocsik.jpg", "sep.jpg", "rms.jpg", "fp.jpg", "al.jpg", "un.jpg", "sep.jpg", "op.jpg", "al.jpg", "oacahu.jpg"];
var bottomRightImages = ["nup.jpg", "clf.jpg", "rffcc.jpg", "sla.jpg", "lqbc.jpg", "pocsik.jpg", "fp.jpg", "np.jpg", "lwtgr.jpg", "lqbc.jpg", "lcsik.jpg", "poss.jpg"];
var i = 0;
var max = 12;
setInterval(function()
{
var index = i % max;
document.getElementById('myimage1').src = "images\\" + topLeftImages[index];
document.getElementById('myimage2').src = "images\\" + topRightImages[index];
document.getElementById('myimage3').src = "images\\" + bottomLeftImages[index];
document.getElementById('myimage4').src = "images\\" + bottomRightImages[index];
i++;
}, 10000);
});
