JavaScript - Generate A Table With Images Using External Javascript.
As a homework assignment, we are being asked to generate a table of images with at least 2 rows and 3 columns from an external javascript function. I've been trying to find some kind of javascript reference for this and I can't. I don't want someone to do it for me, but if I could get a basic example that would be great.
Similar TutorialsHi, I have a problem. please help me in this regard. I have a combobox which contain numeric values from 1-7. i want to generate a table with 2 rows and 4 columns through javascript. Means when a user select numeric value like '3' from a combo box then a page generates '3' tables without refreshing a page. And if a user selects '4' from a combobox then a script generates 4 tables with 2 rows and 4 columns and so on. kindly guide me that how can i mkae this javascript. plz help Greetings, I am looking for either a JavaScript or Coldfusion solution to the following problem. First, there are over 60 million product photos so downloading and resizing the photos using Coldfusion would be very tedious. I would like the display an image within a 100 x 100 pixel container. If the height or width of the image is great than 100 pixels, the image should reduce in size to fit within the 100 x 100 pixel container. I want to avoid pixelation of the images as much as possible. All images are external and not on the local server so I only have an image URL. I would like to hide all images until they are resized appropriately. Does anybody know of a piece of javascript code that can do something similar to this? Sincerely, Travis Walters I am confuseif i use JS.. its should be in <head> but table should be in <body>.. how am i going to use that.. and put images in that table cell using JS??
i have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads. var random = Math.floor(Math.random()*40 + 1) //sets variables for random numbers to generate var random2 = Math.floor(Math.random()*40 + 1) var random3 = Math.floor(Math.random()*40 + 1) var random4 = Math.floor(Math.random()*40 + 1) var random5 = Math.floor(Math.random()*40 + 1) var random6 = Math.floor(Math.random()*40 + 1) //create table function makeTable(lotto) document.getElementById("tableSpan").innerHTML = '<table border="1" id="lotto">'; var caption=document.getElementById('lotto').createCaption(); caption.innerHTML="JavaScript Random Numbers"; var x=document.getElementById('lotto').insertRow(0); var cell1=x.insertCell(0); var cell2=x.insertCell(1); var cell3=x.insertCell(2); var cell4=x.insertCell(3); var cell5=x.insertCell(4); var cell6=x.insertCell(5); cell1.innerHTML='<td class = "normal">'+ random +'</td>'; cell2.innerHTML='<td class = "normal">'+ random2 +'</td>'; cell3.innerHTML='<td class = "normal">'+ random3 +'</td>'; cell4.innerHTML='<td class = "normal">'+ random4 +'</td>'; cell5.innerHTML='<td class = "normal">'+ random5 +'</td>'; cell6.innerHTML='<td class = "red">'+ random6 +'</td>'; } heres the HTML file: <body onload="makeTable('lotto');"> <div id="container"> <div id="header"> <h1>Welcome</h1> </div> <div id="content"> <span id="tableSpan"></span> <input type="button" value="Re-generate Numbers" onclick="makeTable('lotto');" /> </div> { Hi All, i want to achieve an effect like the following, please help 1. i want to get the current time, possibility no from client computer ( sometimes their time is wrong)? i dont know whether can achieve but if cannot, then never mind, just get from client computer. 2. for example now is 1:25 am, i want to generate dynamically every half an hour timing from 2 am(round up) till for example 11 am something like <select> <option>2:00</option> <option>2:30</option> ................ <option>11:00</option> </select> for me this is a bit complicated, anybody can help me? <option>3:00</option> Hello, I'm a complete javascript beginner so sorry if I'm just being stupid I wanted to know if it's possible for me to add a picture (as in a .png file) to a page by clicking on something which would then make an image appear on the screen (which I would then want to be able to drag and move but I made a different thread for that question) I hope this explanation made sense Thank you for your time ok so heres where I stand, I don't know too much about javascript. Just enough to get me by. I am a PHP developer, I know how to do this in PHP but the client insists on doing it through javascript. Basically there are 3 different form values that determine the Premium Death Benefit Ratio. This is the formula the client wants: Premium to Death Benefit Ratio % (Created by formula = Annual (Level) Premium Amount (Divided by) Death Benefit Amount (equals a percentage) That percentage multiplied by Life Expectancy The 3 form values in the formula would be Annual Premium Amount (fypremium), Death Benefit Amount (dbp), Life Expectancy (average_le) I was messing around with javascript trying to figure it out and I have gotten no where since I am not used to writing formulas in JS. Anyways here is what I have so far: Code: function calculateLE(inputFieldId1, inputFieldId2, inputFieldId3, outputFieldId){
var DBR;
var input = document.getElementById(inputFieldId).value;
APA = document.getElementById(fypremium).value;
DBA = document.getElementById(dbp).value;
LE = document.getElementById(average_le).value;
formula = document.getElementById(fypremium).value / document.getElementById(dbp).value = formula3;
formula2 = document.getElementById(average_le).value * formula3;
if { APA = "" } {
document.getElementById(outputFieldId).value = "Error getting Annual Premium Amount";
}
else if { DBA = "" } {
document.getElementById(outputFieldId).value = "Error getting Death Benefit Amount";
}
else if { LE = "" } {
document.getElementById(outputFieldId).value = "Error getting Life Expectancy";
}
else {
document.getElementById(outputFieldId).value = formula3;
}
}
Now I honestly have no clue if I am on the right track but what i've found on the net hasnt really pointed me in the right direction Here is the form values. Code: <input type="text" name="fypremium" id="fypremium" onblur="calculateLE('fypremium', 'dbp', 'average_le', 'premium_dbr')">
<input type="text" name="dbp" id="dbp" onblur="calculateLE('fypremium', 'dbp', 'average_le', 'premium_dbr')">
<input type="text" name="average_le" id="average_le" onblur="calculateLE('fypremium', 'dbp', 'average_le', 'premium_dbr')">
In a nut shell the values for the 3 inputs stated above will determine premium_dbr's value. fypremium / dbp = percentage; average_le * percentage = DBR (death benefit ratio); If someone could point me in the right direction to finishing this id be very greatful. I would like to remove some hosting imposed google ads on my phpbb board. Currently I accomplish this by deleting via javascript all the banners divs when the page is loaded. But unfortunately in that way advertisements are quickly displayed before disappearing. Now I am thinking about a different (neater) approach to my problem: maybe I might write some javascript code which interferes with the one injected by google thus generating the inability to show those annoying divs... Any idea? I've done a bit of searching and I can't find the answer to my question. I'm working on a website for my business. I have some basic knowledge of coding but I'm mostly a code cobbler. I find various pieces and put it together and hope it works so take it easy on me. I have some code to display products on my site. It works fine. We just have a lot of products and for me to add each one by hand was getting ridiculous. I finally had the bright idea to use Javascript to generate the code for me and then copy it back into my actual HTML page. Last night I wrote the code below. It works perfectly except I have to constantly "View Source" in order to get the code. I was hoping to cut down on a step or two and have the code go into a TextArea. From there I can just select it and copy it into the HTML file. It should make things a little quicker and most importantly easier. Maybe after that I'll try to figure out how to write function to select everything in the TextArea and copy it to my clipboard. That would make things even faster. Any help?

I pulled this code from Google's example section to make markers on a v3 Google Maps API (I have added my own lat/long points and corresponding event listeners, of course, but this is still the spirit of the code):
Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
function initialize() {
var map_center = new google.maps.LatLng(39.2,-84.479381);
var store1 = new google.maps.LatLng(39.112456,-84.574779);
var store2 = new google.maps.LatLng(39.314153,-84.261379);
var store3 = new google.maps.LatLng(39.197099,-84.667579);
var store4 = new google.maps.LatLng(39.16836,-84.479381);
var myOptions = {
zoom: 10,
center: map_center,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker1 = new google.maps.Marker({
position: store1,
map: map,
title:"Store 1"
});
var marker2 = new google.maps.Marker({
position: store2,
map: map,
title:"Store 2"
});
var marker3 = new google.maps.Marker({
position: store3,
map: map,
title:"Store 3"
});
var marker4 = new google.maps.Marker({
position: store4,
map: map,
title:"Store 4"
});
google.maps.event.addListener(marker1, 'click', function() {
map.set_center(store1);
map.set_zoom(16);
});
google.maps.event.addListener(marker2, 'click', function() {
map.set_center(store2);
map.set_zoom(16);
});
google.maps.event.addListener(marker3, 'click', function() {
map.set_center(store3);
map.set_zoom(16);
});
google.maps.event.addListener(marker4, 'click', function() {
map.set_center(store4);
map.set_zoom(16);
});
}
</script>
This works without fail, but when I try to use a javascript array to hold my values and loop my way through the marker creation like so: Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
function initialize() {
var map_center = new google.maps.LatLng(39.2,-84.479381);
var store_locations = new Array();
var temporary_stuff = new Array();
store_locations[0] = "39.112456,-84.574779";
store_locations[1] = "39.314153,-84.261379";
store_locations[2] = "39.197099,-84.667579";
store_locations[3] = "39.16836,-84.479381";
var myOptions = {
zoom: 10,
center: map_center,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
for(i=0;i<store_locations.length;i++){
var marker_string = "position: "+new google.maps.LatLng(store_locations[i])+", map: map, title:\"Store "+(i+1)+"\";";
temporary_stuff[i] = new google.maps.Marker(marker_string);
}
var markers = new Array();
for(i=0;i<temporary_stuff.length;i++){
var the_marker = "position: temporary_stuff[" + i + "], map: map, title:\"Store " + (i+1) + "\";";
markers[i]= new google.maps.Marker(the_marker);
}
}
</script>
I get a blank map. Here's a link to the test file: http://rowsdower.freehostia.com/map_test.php It's not throwing up any errors in Firefox's developer or in IE but there it sits, a blank map. I'm sure this isn't clean or optimized code, but it looks correct to me. I've color-coded the code above to show what "for" loops are being used to try to replace which code. Hopefully that makes this more sensible. I haven't even tried to add the listeners yet since I can't get the markers to appear. Can anyone tell me why this isn't working or point me in a more productive direction? Is there a better way already out there that I haven't noticed? Hey I was hoping someone could point me in the right direction here. I'm supposed to add a <script> in the mainContent div of puppies.htm to generate the opening table tags followed by a header row with cells for Picture, Description, and Date Taken. Obviously these are supposed to be taken from the arrays in puppies.js, but how do i organize those arrays into a table. Any input would be much appreciated. thanks. puppies.js Code: var puppyPics = new Array(); var pictureDesc = new Array(); var pictureDate = new Array(); puppyPics[0] = "AllTheKids.jpg"; puppyPics[1] = "susie.jpg"; puppyPics[2] = "princess.jpg"; puppyPics[3] = "wicketAndCarlos.jpg"; puppyPics[4] = "wicketAndGeorge.jpg"; pictureDesc[0] = "New puppies"; pictureDesc[1] = "Susie"; pictureDesc[2] = "This is Princess"; pictureDesc[3] = "Wicket is very social"; pictureDesc[4] = "Wicket and George"; pictureDate[0] = "January 10, 2011"; pictureDate[1] = "January 10, 2011"; pictureDate[2] = "January 10, 2011"; pictureDate[3] = "January 15, 2011"; pictureDate[4] = "January 15, 2011"; puppies.htm Code: <div id="mainContent">
<h1> My Puppies</h1>
<p>I made this page to show off my wonderful puppies! I hope you enjoy their pictures.</p>

<body> <script type="text/javascript" src="/khk.php?klub=khk&user=w"></script> This script works fine, but I get a error: line: 2 character: 1 error: character illegal code: 0 url .... Can anybody help?? Hi, I've posted a previous thread where the code I had wasn't running. I copied that into the head section and it worked. I'd like to know why it doesn't work in the javascript.js file. Thank you very much. Dear All, I got a problem with order of loading external javascript file. I have 2 external javascript files: jsFile1. js and jsFile2.js. And file jsFile2 use an object in file jsFile1.js. So file jsFile2.js have to load after file jsFile1.js. But sometime I got runtime error, because file jsFile2.js is loaded before jsFile1.js I added 2 js files by: document.getElementsByTagName('head')[0].appendChild(jsFile1.js); document.getElementsByTagName('head')[0].appendChild(jsFile2.js); Does anyone know how to solve this problem. Please help. Thank you. Best Regards. Hi all me again I have this bit of code: Code: <script type="text/javascript">
var testvar = "<? print $cards; ?>";
var name = "<? print $name; ?>";
//Create JavaScript array
var testarray = new Array();
//Fill JavaScript array from the converted string
testarray = testvar.split(":#:");
var imagesleft = 10;
var numclicks = 0;
var score = 0;
function clickCard (what,where)
{
var count=0;
for(var x = 0; x < testarray.length; x++)
{
if(what == testarray[x])
{
count++;
}
}
if(count==1)
{
alert("unique");
document.images[where].src = "./images/blank.png";
imagesleft--;
score = score+20;
clicks.innerHTML = "Unique Images to find = " + imagesleft;
if(imagesleft==0)
{
score = score - numclicks;
var r=confirm("Do you want to enter your score in the highscore table?");
if (r==true)
{
document.getElementById('score').value = score;
document.forms["highscore"].submit();
}
else
{
var t=confirm("Do you want to play again?");
if (t==true)
{
document.location.reload();
}
else
{
window.close();
}
}
}
}
else
{
alert("Not unique");
}
numclicks++;
pairs.innerHTML = "Number of Clicks = " + numclicks;
}
</script>
which works a treat but when it is put into a external js file all I get is the alert Not unique and nothing else! any ideas why? Hi Guys, I am tiring to create an external java script which is suppose to change a div background color when mouse over. I have a simple Html file as: Code: <html> <head> <script type="text/javascript" src="MouseJs.js"></script> <link rel="stylesheet" type="text/css" href="MouseCSS.css"> <title>Test Mouse Over</title> </head> <body> <div class="box" id="col"> </div> </body> </html> and a CSS file as: Code: .box {
width: 20%;
height: 100px;
background-color: #4D7530;
float:left;
}
and finally I have a java script file as bellow: Code: window.onload = function()
{
document.getElementById('col').onmouseover = function()
{
document.col.background-color: #FFFFFF;
}
}
Could you please let me know what i am doing wrong here?
