JavaScript - Help With Resetting And Disabling
So I've been working on this code for the day, and when I choose one radio button and click convert, it gives me the value and disables the box that shows the value. When I go to click the other radio button to do another conversion, it freezes up. I really am just trying to figure out how to make this code functionable whether you choose one radio button and do the conversion, or you want to do the other conversion without stalling out. I can't seem to find the bugs since I'm a newbie.
Code: var $ = function (id) {//enables you to use $ instead of all the blah blah blah nonsense
return document.getElementById(id);
}
var temperature = function (){//This function converts the value the user provides
if($("to_celcius").checked == true)//if checked, then do this conversion
{
$("degrees_celcius").disabled = true;
var far = parseFloat($("degrees_fahrenheit").value );
if(isNaN(far))//if its not a number then it gives the alert to enter a valid temperature
{
alert("Please enter a valid temperature.")
return;
}
var far_cel =Math.round((far-32) * 5/9);//conversion assigned to variable
$("degrees_celcius").value = far_cel;
}else ($("to_fahrenheit").checked ==true)//if the other radio button isn't clicked, then this conversion
{
$("degrees_fahrenheit").disabled = true;
var cell = parseFloat($("degrees_celcius").value);
if(isNaN(cell))//if its not a number then it gives the alert to enter a valid temperature
{
alert("Please enter a valid temperature.")
return;
}
var cel_far = Math.round(cell * 9/5 + 32);
$("degrees_fahrenheit").value = cel_far;//conversion variable equals the value of text box "degrees_fahrenheit"
}
}
function reset()//resets the text box fields
{
$("foofoo").reset();
}
window.onload = function(){//handles all the onload activities
$("convert").onclick = temperature;
$("convert").onchange = temperature;
//$("to_celcius").onchange = reset;
//$("to_fahrenheit").onchange = reset;
}
Code: <body>
<form id="foofoo" name="foofoo">
<div id="content">
<h1>Convert temperature</h1>
<input type="radio" name="conversion_type" id="to_celcius" />From Fahrenheit to Celcius<br />

Similar TutorialsHello all, First time back here in a while, but I'm trying to get proficient in JS. I want to make my input element reset its value attribute to blank, which is originally set to "your e-mail". You know the effect you see on forms that have text in them, then with the onclick attribute, you can clear the text in the box. So, after looking around trying to find out what to do, here's what I've attempted. HTML Code: <form id="emailbox" name="form1" method="post" action="">
<div>
<input type="text" name="go" id="go" value="your e-mail" onclick="removeText()"/>
<input type="submit" value="Join" />
</div>
</form>
JS: Code: <script type="text/javascript">
function removeText(){
var form = document.getElementById['emailbox'];
var name = form.elements['go'].value;
}
</script>
What do I do next to complete my objective? I have 3 images that I am trying to swap in and out with eachother. It starts off with the "Good Afternoon.gif" then I have a checkbox that changes it from and switches between the "Eyeball.jpg" and the "Smileys.gif" without going back to the "Good Afternoon.gif. That works perfectly fine and as intended. What does not work is my reset button, it unchecks the checkbox that I created as it should be does not set the image back to the "Good Afternoon.gif". I created goodAfternoon and a goodAfternoonFinal images because I am telling the code to to goodAfternoon.src=Eyeball.src; so I have the goodAfternoonFinal to change it back to the original pic. What am I doing wrong here? Code: ml>

I have a form with a text box that is greyed out unless a checkbox is checked. The problem is if the checkbox is checked and this enables the text box to enter data and I hit reset, the text box does not reset and turn grey. It allows data to be entered. I have both the html reset button and the javascript clear form, but neither seem to work. How do I reset the text box to grey as well if reset is hit? Code: <form method="post" action="" name="resetproblemform" enctype="text/plain" onReset="return confirm('Do you really want
to reset the form?')">

I have a page where a user can select (via check boxes) several categories. Each category is related to a set of possible options (radio buttons) that have numeric values. When one of the options (radio button) is selected, the amount will appear in a text box (input type="text"). The numeric value in the text box will update depending on what category options are selected. However, when the checkbox is deselected, the radio boxes in the <div> are not displayed and I need to remove (reset) the radio button values from the value seen in the text box. Here are some snippets to hopefully expound on what I would like to do. Code: <script type="text/javascript">
var amountNotice = 0;
function notice(options)
{
amountNotice = parseInt(options);
calculateTotal();
}
function calculateTotal()
{
totalAmount = amountNotice;
document.getElementById("total").value = totalAmount.toFixed(2);
}
function toggle(chkbox, group, associatedValues)
{
var visSetting;
if (chkbox.checked == true)
document.getElementById(group).style.display = "inline";
else
{
document.getElementById(group).style.display = "none";
uncheckRadio(associatedValues);
}
document.getElementById(group).style.display = visSetting;
}
function uncheckRadio(associatedValues)
{
for(var i = 0; i < document.getElementById(associatedValues).length; i++)
{
if (associatedValues[i].checked == true)
associatedValues[i].checked == false;
}
calculateTotal();
}
</script>
<style type="text/css">
#groupNotice {display: none}
</script>
.
.
<input type="button" onClick="calculateTotal()" value="Calculate"><br>
<div id="groupNotice">
<b>Required Notice</b>:
<input type="radio" name="Note" onClick="notice(this.value)" value="0"> None
<input type="radio" name="Note" onClick="notice(this.value)" value="2"> Prior Day ($2)
<input type="radio" name="Note" onClick="notice(this.value)" value="2"> Prior Call ($2)<br>
</div>
<form name="CostEstimate" method="post" action="calculator.php">
<input type="checkbox" onclick="toggle(this, 'groupNotice', 'Note'); display('groupNotice','inline')" name="Notice" value=""> Notice
</form>
Everything works except for my uncheckRadio function - not sure if I am identifying the elements correctly, or if I need a totally new approach. My thinking is that the function must be accessed by the checkbox onClick call. Previously I had tried calling uncheckRadio from the notice function before I recognized is was not an appropriate location. Any assistance is greatly appreciated. - c I am having trouble with figuring a way to set my loop up to reset values of the different coin values. Example, when I put in 78, and click calculate, it tells you how much of each coin would be given back. My problem is that I set it up and run it, but when I put different values in back to back to calculate, some of the fields don't reset. I just need some ideas or logic behind what I need to do. Code: var change_out = function(){
do {
var money = document.getElementById("cents").value;
if (money >= 25)
{
var quarters = parseInt(money / 25);
var foo = parseInt(money - (quarters * 25));
document.getElementById("quarters").value = quarters;
if (foo >= 10)
{
var left = parseInt(foo / 10);
var wow = parseInt(foo - (left * 10));
document.getElementById("dimes").value = left;
if(wow==0)return;
if (wow >= 5)
{
var dumb = parseInt(wow / 5);
var pop = parseInt(wow - (dumb * 5));
document.getElementById("nickels").value = dumb;
document.getElementById("pennies").value = pop;
}else{document.getElementById("pennies").value = wow;}
}else if (foo >= 5){
var dumb = parseInt(foo / 5);
var pop = parseInt(foo - (dumb * 5));
document.getElementById("nickels").value = dumb;
document.getElementById("pennies").value = pop;
}else{document.getElementById("pennies").value = foo;}

Hello everyone, I am completely new to javascripts. I want to have a count down timer on my webpage. I already found a script, but it does not do everything I want it to do. I couldn't find a script that did everything I need. I need it to do the following things: - Use the time zone GMT+1 - Reset everyday at a specific time - From 15:00 till 17:30: A countdown (so it shows 2 hours and 30 minutes from the start and count's down to 0 (which will be 17:30) - During 15:00 till 17:30 it shows: "The game is playing" - Once it is 17:30 I want it to reset and countdown till the next day 15:00 - From 17:30 till 15:00 next day it says: "The game will start in" So it is actually 2 countdown clocks in one javascript. One countdown from 15:00 to 17:30 (whilst the game is playing) and one directly starting after it from 17:30 till 15:00 next day. But both are displayed on the same spot. The countdown will be in text. No buttons or fancy images etc. Hope you can help me out. Thanks Code: <html>

Hello! I am playing with CSS3 transitions to show/hide a DIV element. The application will be for a newsletter which will allow a user to show and hide article content. There will be multiple articles. I have a <DIV id="article1" class="content"> and the default height is 0px. When someone clicks the "show/hide article" link I set the height to 250px. A CSS transition on the content class (height) adds a smooth change from 0px to 250px. I have rigged up a simple Javascript function so that when someone clicks the "show/hide article" link, it checks the height of the DIV. If the div is 0px, it should expand the content, if not, it should shrink it. It works when you click the link the first time (i.e. the content div height is set to 250px and the transition works). But when you click it again, it does not set the height to 0px in order to hide the content. I think there is something wrong with the validation of document.getElementById(articleID).style.height ? Any ideas? Thank you! Code: Code: <!DOCTYPE html>
<html land="en">
<head>
<script language="javascript" type="text/javascript">

So I need some help with figuring out how to reset both my text boxes when I click a different radio button so that I can give another value in the textbox area. I am trying to do it without a reset button. Any helpful ideas? I am just confused with the process of resetting the values of both the text boxes in the code.Hmmm......lol I feel like the answer is to put it inline in the <input> tag... Code: <body>
<div id="content">
<h1>Convert temperature</h1>
<input type="radio" name="conversion_type" id="to_celcius" onclick="document.getElementById('degrees_celcius').disabled=this.checked;" />From Fahrenheit to Celcius<br />
<input type="radio" name="conversion_type" id="to_fahrenheit" onclick="document.getElementById('degrees_fahrenheit').disabled=this.checked;" />From Celcius to Fahrenheit<br />
<br />
<label>Degrees Fahrenheit:</label>
<input type="text" id="degrees_fahrenheit" class="disabled" /><br />
<label>Degrees Celcius:</label>
<input type="text" id="degrees_celcius" class="disabled"/><br />
<br />
<input type="button" id="convert" value="Convert" /><br />
<br />
</div>
</body>
Hello all. Complete newbie to this and to be quite honest, completely out of my depth. Ok, I have the following set up on my page - the page essentially uses three different search methods to bring back data in a gridview. 1. A cascading drop down list (ddlBuyer, ddlSub, ddlProd) and an associated radio button radBuyer. 2. An autocomplete textbox (tbxProdAC) that sources product information and an associated radio button (radProd) 3. A text box whereby users specify the number of products they wish to see and (txtHowMany) a subsequent sub category radio button list that breaks the products down further (radTopx) What I would like to do is essentially make the page so that a user can only user one of the above methods and the radio is focused according to what the user first specifies. For example, if they wish to use the ddl method, they should click ddlBuyer, ddlSub and ddlProd and the focus is placed upon the radBuyer. Along side of this, any information that may have been entered into tbxProdAC or txtHowMany is cleared. Alternatviely, should a user use the drop down method then wish to use the third method specified above, once a user clicks in txtHowMany, the ddl should revert back to their original values. I would like to achieve this in the c# code behind and I currently have the following code on my page load event/ I have got to the point where I am going round in circles (mainly because I don't know what I am doing!) so I would appreciate a few pointers. Code: ddlProd.Attributes.Add("onchange", "return SetRadioFocus('" + radBuyer.ClientID + "');");
radTopx.Attributes.Add("onclick", "return SetRadioFocus('" + radTopx.SelectedItem + "');");
tbxProdAC.Attributes.Add("onclick", "return SetRadioFocus('" + radProd.ClientID + "');");
ClientScript.RegisterClientScriptBlock(this.GetType(), "MyScript", @"
function SetRadioFocus(target)
{
document.getElementById(target).checked = true;
}"
, true);
If someone can help me, I would be extremely grateful and it would save me from smashing my head further into my desk. Please excuse my ignorance, brand spanking new to this and feeling more than a little thick. irst post here, i'll try to be simple: I need to create a form where participants of a medical convention register to classes, each class lasts 3 hours, so a person who wants to attend to class starting at 10 am cannot register to 11 am, 12pm and 1pm classes, but he can register to 2pm and so on. There are 3 different classes per hour. i thought doing this using javascript, but i'm absolutely lost. Can you please give me a hint on how to do this? Thanks!! this is the part of the form that has the checkboxes. <form method="post" action="process.php"></form> <input type="checkbox" value="101" name="convention1"> 10 am: Cariovascular desease<br> <input type="checkbox" value="102" name="convention2"> 10 am: Changes on toracic surgeon<br> <input type="checkbox" value="103" name="convention3"> 10 am: New drugs on heart<br> <input type="checkbox" value="111" name="convention4"> 11 am: New drugs on heart (II)<br> <input type="checkbox" value="112" name="convention5"> 11 am: Dynamic process on blood pressure<br> <input type="checkbox" value="113" name="convention6"> 11 am: Aortic disease<br> <input type="checkbox" value="121" name="convention7"> 12 am: Pulmonar Pressure<br> <input type="checkbox" value="122" name="convention8"> 12 am: Open table<br> <input type="checkbox" value="131" name="convention9"> 1 pm: Neurological aspects on heart rate<br> <input type="checkbox" value="132" name="convention10"> 1 pm: Cardiovascular disease (II)<br> <input type="checkbox" value="133" name="convention11"> 1 pm: Mioresponse on heart failure<br> <input type="checkbox" value="141" name="convention12"> 2 pm<br> <input type="checkbox" value="142" name="convention13"> 2 pm<br> <input type="checkbox" value="143" name="convention14"> 2 pm<br> <input type="checkbox" value="151" name="convention15"> 3 pm<br> <input type="checkbox" value="152" name="convention16"> 3 pm<br> <input type="checkbox" value="153" name="convention17"> 3 pm<br> <input type="submit"></input> </form> Ok I just gota ask... I read this originally and nearly killed my self laughing... then my brain got the best of me and my curiosity took over... is it possible to write a javascript code that makes your web browser disable javascript? is it even possible for Javascript to access a web browser in that sort of fashion? Like can a script have that much control? ... or rather lack of control and self suicidal... but anyways Is it possible? Hey all i have this piece of code before that disables the given dates i put into an array. This works great for day 2-30 (out of a 31 day month) but it does not seem to work when i select either day 1 or day 31. For day 1 it blocks out day 1 and i do not want that. The user should be able to select that day since it was selected. It does not do this for any other day. If the user selects day 2 then day 2 is selected on the calender and is not blocked. As for day 31, i don't know whats wrong with it because it never shows me an error. It's the type of error that shuts down the website with "System Unavailable" for about a minute before i can connect to the page again. Here is my code: Code: var disabledDays = ['3-31-2010','3-30-2010','3-29-2010','3-28-2010','3-27-2010','3-26-2010','3-25-2010','3-24-2010','3-23-2010','3-22-2010','3-21-2010','3-20-2010','3-19-2010','3-18-2010','3-17-2010','3-16-2010','3-15-2010','3-14-2010','3-13-2010','3-12-2010','3-11-2010','3-10-2010','3-9-2010','3-8-2010','3-7-2010','3-6-2010','3-05-2010'];
function nationalDays(date) {
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
//console.log('Checking (raw): ' + m + '-' + d + '-' + y);
for (i = 0; i < disabledDays.length; i++) {
if(ArrayContains(disabledDays,(m+1) + '-' + d + '-' + y) || new Date() > date) {
//console.log('bad: ' + (m+1) + '-' + d + '-' + y + ' / ' + disabledDays[i]);
return [false];
}
}
//console.log('good: ' + (m+1) + '-' + d + '-' + y);
return [true];
}
function noWeekendsOrHolidays(date) {
return nationalDays(date);
}
function ArrayIndexOf(array,item,from){
var len = array.length;
for (var i = (from < 0) ? Math.max(0, len + from) : from || 0; i < len; i++){
if (array[i] === item) return i;
}
return -1;
}
function ArrayContains(array,item,from){
return ArrayIndexOf(array,item,from) != -1;
}
Any help would be great! David What have I done wrong here? <INPUT id="purchase" onclick="document.getElementById("purchase").disabled = true;" type="submit" value="PURCHASE"> I need to disable some keys from their default behaviour in Google Chrome on Windows with javascript. The script below works for most keys but not for F10, left Windows key, right Windows key, NumLock and left Alt. (which are the keys I need to disable) Code: <script type="text/javascript">
addEventListener("keydown", function (event) {
if(KeyID == 121 KeyID == 91 || KeyID == 92 || KeyID == 144|| KeyID == 18 ){
event.preventDefault();
}
}, true);
</script>
I have also without luck tried event.stopPropagation () - event.cancelBubble = true - return false og void(). I would like to know if their is a solution or it simply isn't possible to disable the mentioned keys. Hi there, This is my request. I don't know if it CAN be done via JS, but it just seemed likely it could: Basically, I have a table echoed out by PHP: PHP Code: while($row = mysql_fetch_array($result)){ echo "<tr>"; echo "<td>".$row['Name']."</td>"; echo "<td>".$row['gig_count']."</td>"; echo "<td>" .$row['dob']."</td>"; echo "<td>".$row['Mail']."</td>"; echo "<td><a href=\"/records/add_gigs.php?id=".$row['Member_ID']."&?name=".$row['Name']."\"><button class=\"submit\">Add new Gig</button></a></td>"; echo "<td><a href=\"/certsend.php?name=".$row['Name']."&?mail=".$row['Mail']."\"><button class=\"submit\">Make Certificate!</button></a></td>"; echo "</tr>"; And if the value of gig_count is less than 20, then the 'make certificate' button will be disabled. Once gig_count is 20 or more, then it is re-enabled for that particular row. Any code towards this is greatly appreciated. I'm using meta refresh to refresh my web page. I have a small compose email window that appears via ajax when the user clicks on a name. Is there a way I can disable the screen refresh in my ajax code while they are composing their message? Hi everybody... I have some radio group boxes and according to select one of the values, the other values in another radio boxes should be enabled and checked. In the onClick method of each radiobox i call a setDefault() function to reset the value of radioboxes.... (e.g for (i;i<document.NPOrder.pSubstrate.length;i++){ document.NPOrder.pSubstrate[i].disabled=false; document.NPOrder.pSubstrate[i].checked=false; } and after that i disabled and checked the other's value...) Problem: The code in setDefault() doesn't work properly and after disabling the radios, i can't enable them again Please help me and thanks in advance... Hany Hi, I have a checkbox on a page which I have styled using some jquery code. I want the textbox underneath the checkbox to be disabled if the checkbox is ticked and enabled if it is unticked. I tried using javascript to do this but I beleive it didn't work because I have existing javascript/ jquery code on the page. Any help/advice would be fantastic, here is a link to the page : http://recipesuggester.co.uk/index.php Thankyou Hi, I have a HTML table in a form with a submit button.In HTML table I have links present in first three rows for each columns of HTML table.I want to disable those links when user submit the form.How can I handle this in javascript? Please help. Thanks in advance. Anil. Hi, I am trying to submit a form in javascript on clicking 'Button1'.On submission,it will disable the html table 'HTMLTable1' present in it.The code which I am using is as: Code: function OnButton1_Click ( ) {
var oRows = document.getElementById('HTMLTable1').getElementsByTagName('tr');
var irows = oRows.length ;
if (confirm("Are you sure you want Submit?"))
{
for(k=1; k<=irows; k++)
{
if(document.getElementById("list"+k).selectedIndex == 0)
{
document.getElementById("list"+k).selectedIndex = 1;
document.getElementById("list"+k).options[1].style.backgroundColor = "green";
}
}
Saver();
document.getElementById("HTMLTable1").disabled = true;
}
else{
alert("Submit cancelled!");
}
}
But On submit,the html table is getting disabled just for a moment then again it becomes active and user can interact with it.Can anyone tell me where this code is misbehaving? Thanks, Anil |
