JavaScript - Simple Line Of Code... Please Interpret
can some please tell me what this line does...
Code: <div onClick="getElementById('tInfo').onclick();">
Similar Tutorialscould someone comment how this works please? Code: class_name[i].onclick = function() { words(first[this.value]); };
There are some VERY similar questions and answers, but I have been unable to get them to work for me. The simple situation is calculate days since a date with JS, and output it as part of a text line: create variable xxx with subtraction, or datediff() <body> <p>XYZ has been in effect for (xxx) days.</p> </body> Nothing more, & thanks.

FYI datediff() is not an official JS function. What I normally do is get the date as a UTC number (millsecs after an old date) do the math and then convert back. Code: <!DOCTYPE html>
<html lang="en">
<meta charset="utf-8" />
<head>
<title></title>
</head>
<body>
<div id="her" style="clear:both;"></div>
<script type="text/javascript">
var d1 = new Date("january 01, 2015");
var d2 = new Date();
var work = d2.getTime() - d1.getTime();
var xxx = Math.round(work/86400000);
document.getElementById("her").innerHTML = 'XYZ has been in effect for '+xxx+' days.';
</script>
</body>
</html>
The number 86400000 comes from 1000*60*60*24 to convert millisecs to days Hi, I'm trying to do an assignment, and have copied a piece of code to learn while I do, if you see what I mean. Problem is, I'm having real trouble with one of the lines of code. If someone could tell me basically what it does, I'd be very greatful! Here's the code: if (height[i] == -(array[i].height)) The - before (array[i].height) is really confusing me! Thanks in advance! I'm using jQuery+drupal and some jQuery plugins. All is ok with Firefox. But in IE's i'm receiving problem like this. Line: 1 Char: 1 Error: object expected URL: http://businessway.am I have included .js files. How to know where is the problem? In which file? Line 1? Which file? If you can please check with this address: http://businessway.am Ok, I am in a small pickle here. I created a sidebar gadget for work originally with only 4 images that needed to cycle though it. Easy enough script done. Now they have 6 images that need to rotate through. Easy enough again, script done. The issue I have is now I have to re-push this updated html file to all 1000 PC's on my network. Plus every time a change is made I will have to do it again. And we change the images multiple times a month. So what I need help doing if its possible is to modify the html file i am listing below to have a second IF parameter that not only steps the image but also checks to see if the file is even there. This is the spot I need help at. Code: function slideit(){
if (!document.images)
return
document.images.slide.src=eval("image"+step+".src")
whichimage=step
if (step<10)
step++
else
step=1
I wanted to add another part to the IF statement like maybe. Code: If (step<10 && file_exists("http://www.akronlibrary.org/Gadget/Gadget Pic 1.bmp"))
Basically a step that checks to see if I have at that moment a file named gadet pic 1. (I would do or statements for all of the file names) The point is to make this whole thing dynamic, so that I change image 1 on the server and every gadget on every PC looking for image 1 now see the new image. This way I just change the image file name when I want a different image to display. Same thing with the var for the slidelink function. points to a static named html file on my web server and I just change the redirect in the static named html file to go where i want it. I am by NO means a programmer, I am actually a network admin that came up with this idea and I am trying to fumble through it. Thanks in advance! Code: <html>

I'm getting a runtime error on the code in red. Can anyone see anything that is wrong with it? These functions are called by an onBlur by the way. <script type="text/javascript"> //THIS GENERATES QUANTITY OF MATERIALS function generate3() { var tot3 = document.ComplianceForm.materialamount.value; var tbl3 = document.getElementById("quantitymaterials"); if (tot3 > 28) { alert("16 is total amount of materials for now."); } else { for(var i =1; i<=tot3; i++) { tbl3.innerHTML = tbl3.innerHTML + '<tr><td colspan=\"2\"><hr /></td></tr><tr><td>'+i+') Quantity: <input type=\"text\" name=\"qty'+i+'\" size=\"3\"\/></td><td>Description: <input type=\"text\" name=\"material'+i+'\" /></td></tr><tr><td colspan=\'2\' \">Your Truck<input type=\"checkbox\" \/> Other truck<input type=\"checkbox\" \/> Cash<input type=\"checkbox\" \/> Credit Card<input type=\"checkbox\" \/> P.O.<input type=\"checkbox\" \/></td></tr>'; } tbl3.innerHTML = tbl3.innerHTML + '<br>'; } } function remove3() { var tot3 = document.ComplianceForm.materialamount.value; var tbl3 = document.getElementById("quantitymaterials"); for(var i =1;i<=tot3; i++) { tbl3.innerHTML = ""; document.ComplianceForm.materialamount.value = ""; tbl3.innerHTML = ""; } } </script> I'm pretty new to Javascript so don't lay into me too hard. haha thanks. -Ty So frustrating that lately I've been having trouble with the simplest of code, and this is about as simple as it gets.

Thanks in advance. Hi everyone, I've been coding Perl for quite some time, but I'm new to Javascript and can't quite figure this out. I want to call a Javascript function that is sent to the browser via a perl script. When I hard code the string "Fargo" into the code it works just fine, when I pass the word Fargo via a variable the script will not call the function what so ever. Is it possible to call a javascript function via a Perl script with Perl providing all the necessary data? Here is my code: #!/usr/local/bin/perl use CGI qw(:all); use CGI::Carp qw(fatalsToBrowser); use Cwd; print header; print "top<br><br>"; $data = "fargo"; print <<html; <html><head></head>my heading is here<br><body></body> <script type="text/javascript"> function testz(inbound) { document.write("im in ", inbound); } //the script will only work if I uncomment the line below and comment out two lines below //var data1="fargo"; var data1 = $data; testz(data1); </script> </html> html Thanks to everyone in advance for your help. Basically, I have a Simon Says game with very simple functions but I added an image map with buttons that I now want to use, rather than a table with images as buttons. The problem is, now I can't get the game to work with the image map. Can anyone help me?
