JavaScript - Controlling Textboxes With Javascript
Hello,
I need your help. I have 2 checkboxes. How would I control one from the other? Eg. [ ] Option A [ ] Option B - If Option A was checked first and, I put a checkmark in option B then Uncheck Option A and leave option B checked. - If Option B was checked and, I put a check mark in Option A then uncheck Option B and leave Option A checked. How would that be written in Javascript, I am totally confused. Any help with this is much and foremost greatly appreciated. Cheers, J Similar TutorialsI am trying to use JavaScript to manipulate the appearance of a web browser. (1) Initially I need to identify and save the current browser settings (e.g. position, height, width, caption on or off, menubar on or off, border on or off). (2) Then I need to change the appearance of the browser to full screen, no border, no caption, no status bar, no menubar). (3) Finally, I need to return the browser to the initial settings using the settings saved at the beginning. I am a novice at JavaScript and am having a difficult time locating details of the language that permit me to accomplish my objectives.

... in which I would like to use Javascript to control the values in the 'padding'. Code: padding:318px 0 0 316px; May I know how can I use Javascript to control that 'padding' values? Appreciate any help. I am trying to do a custom add to cart to use with paypal and need to utilize javascript to achieve inserting some code or a weight value per the paypal forms' options choice. Here is my dilemma, All of my items have multiple weights, for instance the below example called Aqua Max 100 comes in .5lbs, 1.5lbs., 10lbs., 20lbs., and 50lbs. Paypal allows you to enter weight but it's one weight per item and I would have to create 5 Paypal buttons just for this one item to calculate the different weights per zip code. I need help making javascript insert the following code within the paypal forms' code upon option select before clicking submit? <input type="hidden" name="weight" value=".5"> <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="1.5"> <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="10 <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="20 <input type="hidden" name="weight_unit" value="lbs"> <input type="hidden" name="weight" value="50 <input type="hidden" name="weight_unit" value="lbs"> The code I came up with is wrong as I'm getting an error but I was originally trying to make it enter a weight using a hidden fillable number and without any real javascript training, just alot of googling but I think I'm pretty close. Please take a look at the code I've came up with so far and maybe point me in the correct direction: <html> <body> <form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_cart"> <input type="hidden" name="business" value="test@test.com"> <input type="hidden" name="currency_code" value="USD"> <input type='hidden'text' name='amt' id='amt' value="0.00"/> <table> <tr> <td> <input type="text" name="on0" value="Aqua Max 100">Aqua Max 100</td></tr> <tr><td> <select name="os0" onChange="getamt()"> <option value="select">Please Select</option> <option value="1/2 lb.">1/2 lb. $3.99 USD</option> <option value="1 - 1/2 lbs">1 - 1/2 lbs $7.59 USD</option> <option value="10 lbs.">10 lbs. $25.80 USD</option> <option value="20 lbs.">20 lbs. $42.75 USD</option> <option value="50 lbs.">50 lbs. $86.20 USD</option> </select></td></tr> </table> <script type="text/javascript"> function getamt() { var sh=0; var choice = document.getElementById("os0").selectedIndex; if (choice == 0) { sh=0; } if (choice == 1) { sh=.5; } if (choice == 2) { sh=1.5; } if (choice == 3) { sh=10; } if (choice == 4) { sh=20 } if (choice == 5) { sh=50.00; } document.getElementById("on0").value=sh; } </script> <input type="image" src="https://images.paypal.com/images/sc-but-03.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!" /> <img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"> </form> </body> </html> Hello, I need your help, I can seem to get this to work. I want to be able to use an IIF to check if a textbox empty ie. IIF(textbox1 = "" || textbox = null, "it is empty","it is not empty") This doesnt seem to be working. Any ideas? - Clueless =? Hi there...I have an autosuggest that I got from a friend. My question is ... the autosuggest works well on my business textbox - what would the code look like to get it to work on the region textbox (or how do I get it to work on more than one textbox - can I just make a copy of the js file and change stuff)... Here is the html code for the index.html page with two boxes and a submit button...

Many thanks for hints, suggestions and contributions Hi and thanks for your help, I have two text boxes on my page and a third where I would like it to automatically subtract the two any time either one of them is changed. What is the simplest way to do this? Thanks again for your help, Will i have a form with several headings, then for each heading i have a list of items with a select box filled with numbers. For each heading a maximum of items is allowed, so the user should change the values in the dropdowns and not be allowed to continue until they are less than or equal to their maximum limit. To complicate this, there will be more than one headings on the page, but each one with a different name/id. Eg: Heading 1 Title 1 DROPDOWN1 Title 2 DROPDOWN2 Title 3 DROPDOWN3 So here the max is 10, so the values cannot exceed 10 Heading 2 Title 1a DROPDOWN1 Title 2a DROPDOWN2 Title 3a DROPDOWN3 Title 4a DROPDOWN4 So here the max is 10, so the values cannot exceed 14 thanks Hi, I have some tickboxes and one is marked Other. So what I would like is when someone put a tick in other, to display 5 textboxes name Other 1 to 5 I presume this is done by javscript, but not sure where to start, can anyone help? Also if possible when they untick it, they disapper, but not a must. Each tickbox is independent from each other. It can also use jQuery or Ajax if that helps Hi everyone, Is there a shorter and cleaner way of performing the following: The objective is to get the value/input from the first set of textboxes in the form and copy them to other set of textboxes. Outline of the form is as follows: First set of textboxes Company Address City State Zip Country Select number of users -->1 2 3 User 1 Company Address City State Zip Country User 2 Company Div Address1 Address2 City State Zip Country User 3 Company Address City State Zip Country ============================================= At the moment the code looks like this where (comp,div, addra,addrb,city,state,zip and country) are the name attributes of the first set of text boxes and (comp1.....country1,comp2.....country2, comp3....country3) are the name attributes for the textboxes for user 1,2 and 3 respectively. Code: function compAddress(){
document.form.comp1.value = document.form.comp.value;
document.form.div1.value = document.form.div.value;
document.form.addra1.value = document.form.addra.value;
document.form.addrb1.value = document.form.addrb.value;
document.form.city1.value = document.form.city.value;
document.form.state1.value = document.form.state.value;
document.form.zip1.value = document.form.zip.value;
document.form.country1.value = document.form.country.value;
document.form.comp2.value = document.form.comp.value;
document.form.div2.value = document.form.div.value;
document.form.addra2.value = document.form.addra.value;
document.form.addrb2.value = document.form.addrb.value;
document.form.city2.value = document.form.city.value;
document.form.state2.value = document.form.state.value;
document.form.zip2.value = document.form.zip.value;
document.form.country2.value = document.form.country.value;
document.form.comp3.value = document.form.comp.value;
document.form.div3.value = document.form.div.value;
document.form.addra3.value = document.form.addra.value;
document.form.addrb3.value = document.form.addrb.value;
document.form.city3.value = document.form.city.value;
document.form.state3.value = document.form.state.value;
document.form.zip3.value = document.form.zip.value;
document.form.country3.value = document.form.country.value;
Thanks, Hello, I have an entry form using multiple select boxes as data entry in the upper portion of my page. below i want additional details of the item selected in a table like textboxes by clicking an add button.So whenever i click the add button a new row of text boxes is again created. problem: upon selecting an additional/new item from the select boxes the first row of textboxes doesn't retain it's value it reflects the currently selected values. all the data mentioned above is contained in a single page is it possible? using a classic asp using javascript to do this?please help, i'm really lost..attach is a snopshot of my page... ok guys, i am not very saavy with javascript and I dont know if this is an easy fix or something difficult, but here is my plan. I would like to have 4 divs with content in each and set each to occupy the same web space through absolute positioning. The .js would be for me to have three divs with a display:none and one to have display:block. and then at a set interval, have the divs switch role so that one that was display none is then block and the others are hidden. I dont want to have a page reload and I dont want to work in flash or anything like that, I just need an example of a script that will alternate through a set array of div ids (i.e. "<<div id="ad1"></div> div id="ad2"></div> <div id="ad3"></div> <div id="ad4"></div>, and change the display attribute every 10 seconds or so. Any help would be greatly appreciated thanks so much Hi, Im trying to change the position of a div when a button is clicked. The js is: Code: function curPos() {
objDivStrip = document.getElementById('thumbview');
return objDivStrip.style.top;
}
function up(pos) {
//get objects
objImgStrip = document.getElementById('str');
objDivStrip = document.getElementById('thumbview');
//Get End position
var totImg = (objImgStrip.height - 100) / 130;
var endpos = totImg * 130;
if (pos=endpos)
{
return false;
}
else
{
objDivStrip.style.top = pos - 130;
}
}
and the html on the button is Code: <img id="arrow" src="images/arrow_up.jpg" onclick="up(curPos());" /> The code doesnt work but if anyone could point me in the direction to get it to work your help is greatly appreciated. Cheers Sol Hi, I have a few checkboxes in a form. Some of them work independently, but some make the others go on and off. Specifically the lower ones are controlling the upper ones. Can anyone explain why please? Code: <td> <input type="checkbox" name="weddingitem1" value="Toppers" id="Toppers"/><label for="Toppers" >Toppers<br /> <input type="checkbox" name="weddingitem2" value="Champers" id="Champers"/><label for="Champers" >Champers<br /> </td> I have the following code which adds a dynamically created textbox to a form: Code: function addarow() {
if (count > 5) {return false}
count ++;
addbox = '<input type = "text" name = "txt1" id = "txt1" class = "box">';
document.getElementById("boxes"+count).innerHTML = addbox + "<br>";
}
I am having difficulties in assigning different names/ids to the sequential textboxes, that is "txt"+count to give txt1, txt2 etc. Your assistance will be much appreciated. A child of five would understand this. Send someone to fetch a child of five. Groucho Marx Hi , I have 5 or 6 textboxes and all of them are required ( have required field validators ) .. I want to change their background color to yellow when they are left blank and when the box is filled the backgorund color to white ..Is it possible to do via javascript ..I am a beginer so any help is greatly appreciated hi everybody; i'm using this code to trigger functions with left and right arrow keys.. but they work even if the arrow keys pressed in input boxes.. is there any way to prevent this code to work when user presses the arrow keys in input boxes? Code: document.onkeydown = function(evt) {
evt = evt || window.event;
switch (evt.keyCode) {
case 37:
geri();
gostergeyaz();
break;
case 39:
ileri();
gostergeyaz();
break;
}

Hello! coding forums gals, I am resorting to you for help with a html form that uses javascript to validate data. the form is an invoice for a trip order where the user can select a trip location out of a listbox, a number of people traveling, and where they wish to stay(ex. hotel, tent, etc.) after the user selects one for each category and hits the "add to invoice" button, the fields in the invoice should get filled with the corresponding information. Now my question is how can I write code that will insert information in the next line down and all other lines below if the user wants to schedule more than one trip at a time? basically what logic and programming structure do I need in my function that will know when the first line in the invoice is filled and will add data in the next line down. after I have successfully placed an order, and I want to make another one, how do I get javascript to output data on the second line? Code: <html>

I have a piece of JavaScript code that should validate that a username field is not empty or null and that a telephone field is in the correct format using event handler registration. It seems to be validating fine but if there is an error it still manages to submit. HTML Code: <html>
<head>
<script type = "text/javascript" src = "js/validator.js" >
</script>
</head>
<body>
<form id = "decorForm" action = "">
<table border = "0">
<tr>
<th>Username: </th>
<td>
<input type = "text" id = "myUserName" size = "15" maxlength = "15"/>
</td>
</tr>
<tr>
<th>Telephone: </th>
<td>
<input type = "text" id = "telephone" name = "telephone" size = "15" maxlength = "13"/>
<br />
(999)999-9999
</td>
</tr>
<tr>
<td>
<input type = "submit" value = "Submit" />
</td>
<td>
<input type = "reset" value = "Reset" />
</td>
</tr>
</table>
</form>
<script type = "text/javascript" src = "js/validatorr.js" >
</script>
</body>
</html>
JAVASCRIPT (validator.js) Code: function chkUser() {
// Verifies that the UserName field is not empty.
var myUserName = document.getElementById("myUserName");
if (myUserName.value == "" || myUserName.value == null) {
alert ("Please enter a Username!");
return false;
} else {
return true;
}
}
function chkTelephone() {
// Verifies that the Telephone field value is in the correct format.
var tel = document.getElementById("telephone");
var pos = tel.value.search(/^\(\d{3}\)\d{3}-\d{4}$/);
if (pos != 0) {
alert ("Please enter telephone number in the following format: (999)999-9999");
return false;
} else {
return true;
}
}
function chkFields() {
// Verifes all fields and returns boolean to event handler
// The event handler function
if (chkUser() && chkTelephone()) {
return true;
} else {
return false;
}
}
JAVASCRIPT (validatorr.js) Code: //Register the event handlers for validator.js
document.getElementById("decorForm").onSubmit = chkFields;
I am trying to use this as an example. Hello! coding forums pals, I am resorting to you for help with a html form that uses javascript to validate data. the form is an invoice for a trip order where the user can select a trip location out of a listbox, a number of people traveling, and where they wish to stay(ex. hotel, tent, etc.) after the user selects one for each category and hits the "add to invoice" button, the fields in the invoice should get filled with the corresponding information. Now my question is how can I write code that will insert information in the next row down after the previous row has been filled? basically what logic and programming structure do I need in my function that will know when the first row in the invoice is filled. I'm struggling at the part where when the "add to invoice" button is clicked. some data is added to the invoice, and if the user wants to book another trip, the second trip should be appended in the second row of the invoice. what is happening in mine is that whenever I book another trip, the first one gets overwritten when in fact it should be left intact and the data should get appended in the next row down.

Hi all, I create textboxes dynamically by the following code function addElement() { var contentID = document.getElementById('content'); var newTBDiv = document.createElement('div'); newTBDiv.setAttribute('id','strText'+intTextBox); divname='strText'+intTextBox; newTBDiv.innerHTML = "Text "+intTextBox+": <input type='text' id='divid' +intTextBox name='txtbx[]'/>"; intTextBox = intTextBox + 1; contentID.appendChild(newTBDiv); } It works fine,but i want to get the values and validate it so i use the following code.. var idval=new Array(); for(var i=0;i<intTextBox;i++) { idval[i]=document.getElementById('divid').value; alert(idval[i]); } but it didn`t work out,Any suggestions really helpful. Thankyou. |
