JavaScript - Javascript Help - Creating A Times Table From User Input
Hi, I'm very new to Javascript and I'm stuck. I am trying to create a js script that will prompt the user for a times table (example the 5 times table, the 7 times table, etc.) & prompt the user for 2 more values; the 'start' number and 'end' number. So there would be 3 numbers total the user must input. The script should present a 'warning' message if the user inputs letters or negative numbers. I have come very close to getting it too work but can't quite get past the last hurdle. Upon entering the 3 numbers, the output should look similar to this: (the 5 times table starting with 1 and ending with 12)
The 5 times table 5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25 5 * 6 = 30 5 * 7 = 35 5 * 8 = 40 5 * 9 = 45 5 * 10 = 50 5 * 11 = 55 5 * 12 = 60 I have placed the js script code on pastebin.com and below. The pastebin link is: http://pastebin.com/2NZPiFH9 Code: function writeTimesTable(timesTable, timesByStart, timesByEnd)
{
for (;timesByStart <= timesByEnd; timesByStart++)
{
document.write(timesTable + " * " + timesByStart + " = " +
timesByStart * timesTable + "<br>");
}
}
var timesTable;
while ( (timesTable = prompt("Enter the first number in the times table. Enter -1 to exit.", -1)) != -1)
{
while (isNaN(timesTable) == true)
{
timesTable = prompt(timesTable + " is not a valid number, please retry.",-1);
}
if (timesTable == -1)
{
break;
}
document.write("<br>The " + timesTable + " times table<br>");
writeTimesTable(timesTable,1,12);
}

How would I track how many times a user hit the OK button when prompted with a message using document.writeln?
Here's part of the code, problem I have is I have it set up for 5 rows, I need it to be able to make more than this, but not sure how many more, this is dependent on user input, how should I go about this? Also how would I go about making the users orders correspond with the right item number? I'd need to sort the array somehow? document.write('<table border="1">'); document.write("<tr>"); document.write('<th colspan="5">ORDER</th>') document.write("</tr>"); document.write("<tr>"); document.write('<th align="left">Item #</th>'); document.write('<th align="center">Name</th>'); document.write('<th align="center">Price</th>'); document.write('<th align="center">Quantity</th>'); document.write('<th align="center">Total</th>'); document.write("</tr>"); document.write('<td align="center">0</td>'); document.write('<td>' + productName[0] + '</td>'); document.write('<td> $' + sausagePrice + '</td>'); document.write('<td> ' + orderItemQty[0] + '</td>'); document.write('<td> ' + sausageTotal + '</td I found this code sample that when a user clicks somewhere on the image, then an "X" will appear. I would like to have the "X"s remain visible even when the user clicks on a different area of the image. As you can imagine, a user clicks clicks clicks then there are "X"s everywhere. How do I do this? Do I need to create more "div" tags with the mouse click locations? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Mouse position</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta http-equiv="Content-Style-Type" content="text/css"> <meta http-equiv="Content-Script-Type" content="text/javascript"> <script language="JavaScript" type="text/JavaScript"> var posx; var posy; function getMouse(e){ posx=0;posy=0; var ev=(!e)?window.event:e;//IE:Moz if (ev.pageX){//Moz posx=ev.pageX+window.pageXOffset; posy=ev.pageY+window.pageYOffset; } else if(ev.clientX){//IE posx=ev.clientX+document.body.scrollLeft; posy=ev.clientY+document.body.scrollTop; } else{return false}//old browsers } function showP(){ document.getElementById("div2").style.visibility="visible"; document.getElementById("div2").style.top =(posy-10)+'px'; document.getElementById("div2").style.left=(posx-6)+'px'; } </script> <style type="text/css"> .div1 {position:absolute;top:100px;left:100px;visibility:visible;z-index:5} .div2 {position:absolute;top:0px;left:0px;visibility:hidden;z-index:1;color:black;} .div3 {position:absolute;visibility:hidden;z-index:10;font-family:monospace;font-size:20px;font-weight:900;color:black;} </style> </head> <body onmousemove="getMouse(event)"> <div id="div1" class="div1"> <img src="./yourImage.jpg" onclick="showP()"> </div> <div id="div2" class="div3"> X </div> </body> </html> Hello everyone, I'm new to the programming world so please be kind I'm trying to find a code which would take the input value entered in a form field and on click direct you to a page which corresponds with what was entered. So for example: Enter "5" in field. Click Submit. Page opens up (which in fact would be an html file on my server called... 5.html) ( i would want to create 10 pages for values entered from 1-10... each value having a unique result when entered and clicked) I have no idea how to put this all together, i've been searching everywhere. Any kind of help would be appreciated. I have a question is it bad or what are the disadvantages of doing what I am going to explain. I want to put the same javascript file two time in the same page e-g Code: <script type="text/javascript" src="http://www.mydomain.com/javascript.js"></script> <script type="text/javascript" src="http://www.mydomain.com/javascript.js"></script> Now many people will ask why would I want to do that, well the reason is that I am using blogger and blogger doesn't let me see all code from which the page is made rather split it into two parts named as POSTS and EDIT HTML. So I am going to place this script in those both areas but at the end when the page loads it is actually going to two the same script two times which is not error. Another question would be why am I not using same script in one place rather than two places if at the end the page code is going to become one. Well the answer would be because that script is used by other scripts too so I CAN'T CHANGE THE LOCATION if I do so, then the script stops working. First off I didn't know whether to post this here or in the PHP section since it deals with both, but mostly JS. I have a PHP scraper that scrapes the job title, company name and location from a website and stores them in separate arrays. These values are then extracted out one at a time from the array and stored into a string, that is then passed to a Google Maps API. I can make this successfully happen once, the thing is I need to do it multiple times. I have an idea on what I should do but don't really know how to implement it (correctly). The idea I had was to create a function in the JavaScript section that accepts three values from PHP. This function would be called in my PHP for loop that extracts the values from the array into a string. The thing that confuses me is that the Map function is called via <body onLoad="initialize()">. Here's the link to my code I am trying to create a text area input filed for user input, and i want to be able to allow the user to format thier text, just like the ones used in this user forum. I am writing my website in html, php, javascript and css with a MySql database. I am trying to understand how to create such an format-able text area for input. Any ideas? Thank you; Ice So I have been working on this exercise for about a month. In the book I am reading it say's this:"For each number that the user enters, the text boxes on the web page should display: the last score that was entered, the number of scores that have been entered, the total of these scores, the average score, the best score, and the worst score. When you write the code for this function, you should enclose the prompt method within a loop, but you decide which type of loop is best for this application. Now, write and test the code." The first peice of code is my HTML, and the second piece of code is the function that I have to start from in a .js file. I just seem to be confused at how my structuring needs to be. The 999 in the function is what the prompt says to enter to escape. Code: <body>
<div id="content">
<h1>Using Loops</h1>
<label for="lastScore">Last Sco </label>
<input type="text" id="lastScore" /><br />
<p></p>
<label for="scoreCount">Score Count:</label>
<input type="text" id="scoreCount" /><br />
<label for="scoreTotal">Score Total:</label>
<input type="text" id="scoreTotal" /><br />
<p></p>
<label for="scoreAverage">Average Sco </label>
<input type="text" id="scoreAverage" /><br />
<label for="bestScore">Best Sco </label>
<input type="text" id="bestScore" /><br />
<label for="worstScore">Worst Sco </label>
<input type="text" id="worstScore" /><br />
<p></p>
</div>
Code: var process_test_scores = function () {
var testScore;
testScore = parseInt(prompt(
"Enter a valid test score between 0 and 100.\n" +
"To end test score entry, enter 999.", 999));
}
In a normal chatroom, when the user "says" something, the text will be displayed normally on a line with the date/time attached like the example below. 2011/11/09 Capypara: Blah balh blah I would like to make it so that the text typed in by the user will appear inside a graphic (square, or those chat bubbles) like the example below. The graphic will only appear when a user says something, so essentially both the graphic and the text will appear together. ~~~~~~~~~~~~~~~~~~~~~~~~ | | | 2011/11/09 Capypara: Blah balh blah | | | ~~~~~~~~~~~~~~~~~~~~~~~~ Is it possible to go about doing this? Thanks for reading this. Hello all, First off I would like to say a big hello and thank you to the forum for helping me with code over the years...

Hey, so i've been learning basics and I can get the following code to work as a prompt and I thought hey, I wounder if I can get it to work of a UI system, so I edited the code and got this Read Below Post Can you please help me to find where I am going wrong.

My customers often have hundreds or thousands of photos and want captions on lots of them. I want to post a photo gallery with a user input form. I've created a simple form, but I want the user to be able to save comments straight to the gallery so I can look at them... it's only a very simple form and isn't quite finished yet, oh by the way, I'm not sure how to use the check box... but, i'll work on that.

Dear expert (Ok, i am new to this and should maybe not address this as a letter ) I hope someone can help me ... this is what i want to achieve (I am using frontpage) I want to create a table (this i can do!) that require a user input (number of guests). It then has SEVERAL options: - Select an option from a drop down list, and a price is then loaded from somewhere to create a total for that option and display it in the table (And keep that total for adding later) - Check a box, and if checked it creates a further calculation, displaying and storing the number for further calculation. a number of the above options, and a grand total on the bottom. I found more or less a page on a site that does what i am looking for, but after looking at the code, i have even LESS of an idea how it works Can someone PLEASE help me, or point me in the right direction? (I am not looking for someone to just write the code for me, as this will not teach me anything, and i want to learn) Below is a link to the example .. http://www.ouma-se-kombuis.co.za/test.html Thank you! Hi there, I'll try to be brief: When a user submits a website in the input field on my site, I'd like there to be a background process that takes a screenshot of that website and then displays that image to the user. This website does it perfectly. The user writes the website to the right, and the screenshot is displayed to the left. I'm looking for a free alternative, and read that perhaps webkit(s) might be the solution? I'm a total newbie when it comes to this so any feedback is gold to me. Thank you so much guys/gals. Hi I have a form with some input tags, and when the user submit the form I which if a new hidden tag get submitted with the value the user did tip. I am thinking for doing that but not sure if it is the right thing : Code: <form method="POST"
<input type="text" name="{actionForm.Name}" id="username">
<input type="password" name="{actionForm.Passwd}" id="password">
<input type="hidden" name="usernameh" value="document.getElementById('username')">
<input type="hidden" name="passwordh" value="document.getElementById('password')">
</form>
Is it alright ? I mean when the user enter the username and password, the hidden tags should contain those two values that the user has made. Hey everyone, I've looked around quite a bit and can't seem to find anything but I was wondering if there is some open source software offering a text editor/input field similar to the one used on this forum when submitting a comment or thread? Where you can click a bold button or Italic button or URL button to structure it? Thanks Josh |
