JavaScript - Create Javascript Buttons That Increments A Variable So User Can Effectively Scale Th
I am trying to create three buttons that will scale the page up, down, or reset to a default value. I would like to base that incrementing on a global variable declared in javascript:
Code: var canvasWidth = 600; Desired incrementing would be in sets of 200, so that when the user clicks zoom in once, the value is 800 and the page is redrawn, twice to 1000, and so on. All of the visual elements of the page are created in javascript and are sized based on this variable. Very little is done on the HTML page visually, except for a little display organization, so if possible I'd like to be able to complete this task mainly in the javascript file. Does this make sense? Similar Tutorialshello, I have a textbox in my .net page, and totally new to java script. How do i get a script that will count the data being written in the text box to show increments of 100 and write the value to the bottom of the textbox. e.g. When u get to 100, at the bottom it says "1st hundred" ... and to 200 it writes "2nd hundred" UP to 500 ??? Please help thanks I want to use javasript to create a new html page named from a text field in a form. Then I want to use javasript to copy all of the form fields to the new html page that was created using javascripting. I am creating a user are using a Javascript password login. With most of them the page is the user name or password. So this is why I am looking to do this. I use web 1000 a free host and they will only let me use javascripting. Any info or help would be great thank you
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 need someone who can help me create javascript code which will create a hyperlink string with a changing variable: This script should write and execute a hyperlink string which opens a separate pop-up window, nothing more. No image files, no subfolders, forget all that stuff. JUST A HYPERLINK. The hyperlink SYNTAX does all the work in loading and selecting the images, NOT THE SCRIPT. There is only one changing variable, the value following clipart_id= Here is the basic hyperlink syntax: <a href="http://www.websitename.com/clipart/manipulate? clipart_id= 00000 &path=%2Fclipart%2Feps%2F&lockRatio=true&width=500&height=500"></a> THERE ARE ALWAYS 2 WINDOWS: ONE WINDOW HOLDS THE HTML; THE OTHER IS A POP-UP WINDOW (The opened hyperlink) The basic html page will contain only 2 objects, an input box and a NEXT BUTTON. Step 1: Initialize the variable from an input box, this variable is used to set the value following clipart_id= which is part of the hyperlink syntax Step 2: The user inputs the initial variable which is used to write the first hyperlink string; click NEXT to launch the first pop-up window Step 3: For each subsequent action Click NEXT - OnClick - This ADDS +1 to the initial variable, this variable is passed to be inserted in a new hyperlink string AND then launches a NEW hyperlink to open a NEW popup window. This is an infinite type of action which advances the value of clipart_id= every time the NEXT button is clicked. Each time you click the NEXT button it advances a counter which executes a NEW hyperlink in a NEW popup window. The only thing that ever changes is the variable after clipart_id=, BUT the entire url syntax of the hyperlink string must be maintained exactly as shown below. If you change the syntax it will not work. So, if the first value to start with is lets say 13000 ; this is input in a box; then the first hyperlink string will automatically be written and open using this: <a href="http://www.websitename.com/clipart/manipulate?clipart_id= 13000 &path=%2Fclipart%2Feps%2F&lockRatio=true&width=500&height=500"></a> Click the NEXT BUTTON and now a new hyperlink window will open which reads like this: <a href="http://www.websitename.com/clipart/manipulate?clipart_id= 13001 &path=%2Fclipart%2Feps%2F&lockRatio=true&width=500&height=500"></a> click the NEXT BUTTON and now a new hyperlink hyperlink window will open reads like this: <a href="http://www.websitename.com/clipart/manipulate?clipart_id= 13002 &path=%2Fclipart%2Feps%2F&lockRatio=true&width=500&height=500"></a> And so on and so on... Nothing else changes. So the "nextpath" after a CLICK is a complete new hyperlink string which contains a vew variable for the value following clipart_id= All I am trying to do is execute a standardized hyperlink string with one changing variable. CAN ANYONE HELP ME TO WRITE THIS CODE? Hello, I am working on a tool for hardware quoting, I'm currently trying to add a button for adding line items to the quote. Here is what I currently have: The HTML: Code: <html> ... <input type="button" id="sbutt" onclick="buttinc()" value="Click Me" /> <div id="txtarea"></div> ... </html> The script: Code: vbutt = 0 function buttinc() { var buttona = document.getElementById("txtarea"); if (vbutt<100) { buttona.innerHTML="<div id='newdiv" + vbutt + "'></div><br />"; var buttb = document.getElementById("newdiv"+vbutt); buttb.innerHTML = "some text" + vbutt + "close tags and stuff"; vbutt = vbutt + 1; } } Now, it is sort of working the way I expect. When the button is clicked, it creates the new div, starts the id at 0, and increments the div id each time the button is pressed afterwards. It also displays the text (buttb.innerHTML) in the new div. However, it only increments the id of the same div, it doesn't create a new div under the first one. What I am hoping for is: click 1 : <div id="newdiv0">0</div> click 2 : <div id="newdiv1">1</div> click 3 : <div id="newdiv2">2</div> etc What it is doing: click 1 : <div id="newdiv0">0</div> click 2 : <div id="newdiv1">1</div> (newdiv0 disappears) click 3 : <div id="newdiv2">2</div> (newdiv1 disappears) What am I missing? Any help is appreciated. Hi, I am new to indesign javascript.

I am trying to setup a donation form for a friend, where someone can click radio buttons for set donation amounts, or click the "other" radio buttons and enter a different amount. The donation amount is then passed over to a secure credit card entry page, hosted by a 3rd party merchant. I can set up all the pre-defined radio buttons to correctly pass on the donation amount to the credit card page, but I cannot figure out how to work the "other" radio button amount. Any help would be very much appreciated! Thanks! Codes for Dropdown menu based on radio buttons selection needed!? I need urgent help with this: I need codes for a dropdown menu that is altered by radio buttons. I want to insert the value selected from the dropdown menu into a table. I have a form, that when the user click Submit, I need a php variable to be echoed to the page. This is for an upload page. So when they are waiting for the file to upload, it will say "Uploading..." until the upload is complete. All I know so far is I need to create a javascript function and include it in the submit button. This is all I have so far in the submit button tag: onClick="Transferring();" Now I need to figure out the code to include in this function. Any ideas? window.onload = initAll; function initAll() { document.getElementById("Message").onfocus = focusHandler; document.getElementById("Message").onblur = blurHandler; } function focusHandler() { document.getElementById("helpYou").innerHTML = "<span class=\"helpMessage\">Hey " + theName + "You should add Lasting Flash to your Facebook!</span>" } function blurHandler() { var helpMessage = document.getElementById("helpYou").innerHTML = ""; } function nameHandler(frm) { var theName = frm.firstName.value; } Quote: When I insert theName variable within the span the code completely does not work. I am accessing a text field when the user enters his name and then a small pop up later that includes the users name when another field is clicked on. Ok I am very very new to java to the point where I only know how to use pre-made javascripts in my php code so be gentle. First, here is part of a form I have: Code: <select name = "pulmonologist" > <option selected="" value="">---Select--- <option value="none">None</option> <?php while ($row2 = mysql_fetch_assoc ($results2)) { ?><option value = "<?php echo $row2['staff_name'];?>"><?php echo $row2['staff_name'];?></option> <?php } ?> </select> Ok now I want to echo the value that the user selects on the SAME page (i.e. before the submit button is pressed) (so I can't do it with php, I need javascript) like this: Code: <input type="submit" value = "Contact <?php echo $pulmonologist;?>" /> Can you tell me how to do this? Thanks! Hi! I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function.

Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated how can i make a button that takes the user to the top of the page without the url#top being displayed in addy bar? i just dont like the way it looks thanks peeps To be clear my approach to coding is basically that of building some kind of Java Frakenstein's Monster... which also explains why everything I create invariably ends up in a windmill on fire... This is what I have managed to put together so far: Code: <script type="text/javascript"> var homeDown = new Array() homeDown[0] = "images/home001.png"; homeDown[1] = "images/home002.png"; homeDown[2] = "images/home003.png"; homeDown[3] = "images/home004.png"; homeDown[4] = "images/home005.png"; homeDown[5] = "images/home006.png"; homeDown[6] = "images/home007.png"; homeDown[7] = "images/home008.png"; homeDown[8] = "images/home009.png"; homeDown[9] = "images/home010.png"; homeDown[10] = "images/home011.png"; homeDown[11] = "images/home012.png"; homeDown[12] = "images/home013.png"; homeDown[13] = "images/home014.png"; homeDown[14] = "images/home015.png"; var homeOver = new Array() homeOver[0] = "images/image001.png"; homeOver[1] = "images/image002.png"; homeOver[2] = "images/image003.png"; homeOver[3] = "images/image004.png"; var x=0; function NormalImage() { document.getElementById("button1").src="images/home.png"; } function MouseOver() { document.getElementById("button1").src=homeOver[x]; x++; setTimeout("MouseOver()", 8); } function MouseDown() { document.getElementById("button1").src=homeDown[x]; x++; setTimeout("MouseDown()", 8); } </script> ...and the HTML: Code: <a href="http://www.google.com"> <img id="button1" src="images/home.png" onmousedown="MouseDown(button1)" onmouseover="MouseOver(button1)" onmouseout="NormalImage(button1)"/> </a> I'm sure that's probably the wrong way of doing it but it vaguely works. What I ultimately want is a button that will play the long image sequence on click and the shorter sequence on mouse over. However at the moment it appears that the states of the mouse being over and clicked are clashing so I need something to ignore mouseover images on click and another bit to reset the count on mouseover so it can play again. If I remove the mouseover event the animation on mousedown plays well, though I suspect it might be necessary to preload the images when it's online. Alternatively if anyone feels like writing a much easier bit of script that will do the same thing and slap me for being stupid that is acceptable too... I have the following buttons ... Code: <input id="newTaskButton" type="button" name="Good Morning" value="201" /> <input id="newTaskButton" type="button" name="Hello World" value="201" /> ... and the following javascript ... Code: <script type="text/javascript"> $(document).ready(function() { $("#newTaskButton").click(function() { alert(" " + document.getElementById("newTaskButton").name); }); }); </script> ... but I am having some trouble having the second button to response. My objective is to have 2 or more button that have the same click function (in this case, newTaskButton) but when clicked, it will produce different response. (in this case, the first button will response 'Good Morning' while the second button will response 'Hello World') Appreciate any help. Alternatives are welcome too. Hello. I am a new user. I have got a website, www.eastbourneinks.co.uk where the quantity buttons (+) & (-) do not work on most computers where I have had feedback. Is there any way of making them work on any/all computers. This is one of the pages: http://eastbourneinks.co.uk/product/...nk-cartridges/ Many thanks. Phil. Hi, I'm a year 11 student studying GCSE computing. I'm doing a project and I need to conduct some primary resarch, so I would be grateful if someone could explain to me how to go about coding radio buttons in a HTML web page which uses JavaScript. Thank you! I'm currently working at school on a website and I cycled through aloooot of tutorials, but I couldn't find anything >.< so the qeustion is how to make a VERY simple javascript div tag replacer using buttons. so if I click for example button 1 then I want div tag 1 replaced with div tag 2 and when you press button 2 div tag 1 or 2 gets replaced with div tag 3. the closest tutorial I found was: Replace one div with another |
