JavaScript - Updating Input Boxes
In a form I have two input boxes (ids of return1 and return2) with default values of 0 and a span element (id return3). The span's value is initalized to 0 on page load, and it updates when a button is clicked that calculates x - value of return1 - value of return 2, where x is calculated elsewhere.
Form code: Code: Month 1: <input size="7" type="text" value="0" id="return1" name="return_1"> <input type="button" value="Calculate Remaining Amount" onClick="thirdReturn();"> Month 2: <input size="7" type="text" id="return2" value="0" name="return_2"> Month 3: <span style="color:black; font-size:14px;" id="return3"></span> ThirdReturn code: Code: function thirdReturn() {
var first_return = document.getElementById("return1").value;
var second_return = document.getElementById("return2").value;
first_return = first_return.replace(/\,/g,'');
second_return = second_return.replace(/\,/g,'');
var combined = Number(first_return) + Number(second_return);
if (typeof this.remaining_pipp_amount == "undefined") {
alert('Please select a Flex option');
}
else{
if (combined > this.remaining_pipp_amount){
alert('Return Amount Exceeds Credit Amount');
}
else{
var temp = this.remaining_pipp_amount - combined;
var third_return_amount = document.getElementById("return3");
third_return_amount.innerHTML = addCommas(Math.round(temp));
}
}
}
I am trying to change it so that if return2 is zero when the button is clicked, return2 = x - return 1. Here is what I have: Code: function thirdReturn() {
var first_return = document.getElementById("return1").value;
var second_return = document.getElementById("return2").value;
first_return = first_return.replace(/\,/g,'');
second_return = second_return.replace(/\,/g,'');
var combined = Number(first_return) + Number(second_return);
if (typeof this.remaining_pipp_amount == "undefined") {
alert('Please select a Flex option');
}
else{
if (combined > this.remaining_pipp_amount){
alert('Return Amount Exceeds Credit Amount');
}
else{
var temp = this.remaining_pipp_amount - combined;
if (second_return == 0){
var new_second = document.getElementById("return2")
new_second.innerHTML = Math.round(temp);
}
else{
var third_return_amount = document.getElementById("return3");
//alert (temp);
third_return_amount.innerHTML = addCommas(Math.round(temp));
}
}
}
}
Does anyone know why this doesn't work or what can be done to fix it? Thank you! Similar TutorialsI am stuck on this question. 1. To set the value contained in a field such as an input box, you must use the ____________________ property. This is based on Javascript. What type of properties are used for fields in an input box? Thanks Hello guys, Could you please help me with JavaScript that updates input by onKeyUp event. By updating input name products_data[XXXXXX][purchase_price] or input name products_data[XXXXXX][av_factor] shoul be updates input name products_data[XXXXXX][price] by formula: products_data[XXXXXX][purchase_price] * products_data[XXXXXX][av_factor] = products_data[XXXXXX][price] Because form has alot of integer values for each id: XXXXXX it need to be changes price for exactly id, not all. Code: function updatePrice() {
var purchase_price = 100
var av_factor = 3;
price = purchase_price * av_factor
}
<form name="product">
<input type="text" name="products_data[29796][purchase_price]" onKeyUp="updatePrice()" />
<input type="text" name="products_data[29796][av_factor]" onKeyUp="updatePrice()" />
<input type="text" name="products_data[29796][price]" />
<input type="text" name="products_data[29797][purchase_price]" onKeyUp="updatePrice()" />
<input type="text" name="products_data[29797][av_factor]" onKeyUp="updatePrice()" />

<input type="text" name="products_data[29798][purchase_price]" onKeyUp="updatePrice()" />
<input type="text" name="products_data[29798][av_factor]" onKeyUp="updatePrice()" />
<input type="text" name="products_data[29798][price]" />
...
</form>
Thank you for any suggestion Best Regards I can't figure this. Basically I have a dialogue pop out box. When you type a value in the pop out box,and press enter, it will change the value in the input boxes. Let say I have five input boxes, four of the input box has 7 as value,the last input box has 15 value. When I type 8 and enter, it should change only the value of 15(from 15 to 8) as 15 is greater than 8. If I type 4, it should change all the values of input boxes as all of the input box values are greater than 4. I have set the condition to 18 as input boxes are 18 columns. jsNewDisc is the user input value. Below are some pieces of codes. Of course if I type 5 and enter, this condition will change all the values in the five input boxes as they are all of greater value. If I input 8, input box that has a value of 15 will be the only one that will be change as it has greater value. Code: for (a=1;a < 18; a++){
if(document.getElementById('R4'+ a).value>jsNewDisc){
document.getElementById('R4'+ a).value = jsNewDisc;
}
}
This little script works nicely in IE, and FF but fails in Chrome. It saves the contents of input boxes and displays them next time the page loads: (the cookie functions are the usual ones) Code: window.onload = function()
{
var theInputs = document.getElementsByTagName('input');
for(var i = 0; i < theInputs.length; i++)
{
if(theInputs[i].type == 'text')
{
theInputs[i].onkeyup = function()
{
createCookie(this.name,this.value,9999);
}
}
if(readCookie(theInputs[i].name+'val') != null)
{
theInputs[i].value = readCookie(theInputs[i].name+'val');
}
}
}
Is there an obvious reason why Chrome is not doing this? Hello all, I have a requirement where i need to take an IPv4 address as an input, my web page has 4 text boxes. If i have a address like this 255.255.255.255, my program jumps into the next text box without any problem as soon as i enter the 3 digits. i dont need to press any tab or any other key to go to next text box. In case of an address like 12.24.12.3, i have to press <tab> to jump into the next text box, My project requirement says that it should work with '.' (dot) char as well. SO here is my actual requirement i need to jump into the next text box as soon as user enters a dot (.) char without displaying the dot into the text box. I am writing this program in perl CGI. Thanks, Vaibhav I am working on a job calculator. I have 2 txt input boxes titled "project_rate_field" and "project_time_field" as well as a third box .. "project_pay_total_field" for output.. I need to multiply the rate field and the time field and output the total into the third box. I've never really used javascript before so I dont know much about it or how to write it but im trying to learn. Here is my .js file ... Code: function project_pay_details()
{
var rate = document.getElementById("project_rate_field").value;
var time = document.getElementById("project_time_field").value;
var total = (rate * time);
project_pay_total_field.value = "$" + total;
}

I need to know what im doing wrong because this obviously doesnt work. Hello there, Problem: I was able to see problem only in IE6 Form input fields not clickable and not accepting inputs + Can't even select text or perform most right-click functions. URL: http://www.webhostingkit.com/a/cgi/p...usercontactall Was wondering if anyone can help me out with this weird problem. Not sure why, but none of the input form fields are able to accept values or even clickon them. Site displays just fine in IE, however anywhere on the site, when user tries to input, it just won't show happen, any idea on what is wrong or how to fix this? Thanks again. ** Edit ** If anyone has IE6 installed can you please test it, cuz I am thinking it might be just the standalone version of IE I have might be having the issue, as in that IE, some major sites (including yahoo.com) are having the same issues. I've been playing around with a madlibs exercise while trying to learn simple javascript. I have three input boxes and a button display an alert containing the input from the boxes. Am I right to be assigning variable names to the values from the text boxes and then referencing those variables in my alert? I'm sorry if this is a dumb question but I've been working on it for hours and can't get past this point. Inset a name: <input type="text" id="textbox1" size="10"/> </br> Insert a verb : <input type="text" id="textbox2" size="10"/> </br> Insert a place: <input type="text id="textbox3" size="10"/> <input type="button" value="CLICK WHEN FINISHED" onClick="name = document.getElementById('textbox1').value; verb = document.getElementById('textbox2').value; place = document.getElementById('textbox3').value; alert('Mad Lib :' + name + " " + verb + " " + place);" /> I have a problem with adding new inputs to a form (if and when required), Internet Explorer is fine but in Firefox if any previous input fields are filled when the more button is clicked they get reset to blank. JS: Code: fields = 0;
function addInput() {
if (fields != 100) {
document.getElementById('input').innerHTML += "<input type='text' name='input[]' size='30' />";
fields += 1;
} else {
document.getElementById('input').innerHTML += "<br />Maximum 100 fields allowed.";
document.form.add.disabled=true;}
}
form: Code: <form action="index.php" method="post"> <div id="input"> <input type="text" name="input[]" size="30" maxlength="15" /> </div> <!-- button --> <div id="more"> <input type="button" onclick="addInput()" name="add" value="More" /> </div> <!-- // button --> <input type="submit" name="submit" value="Submit" /> </form> as usual any help is appretiated .. I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. Hi, i want to set an input value to the same value as the input selected from another input on the same form so when the user selects input 1 i want the hidden input2 to get the same value im guessing i use onsubmit because its hidden so there wont be a focus or blur this would be part of the input Code: onsubmit="(this.value = this.othervalue)" othervalue being the other input name="othervalue" is that the correct syntax Hi, I am creating a web page which automatically updates one image every 5 seconds. I use ajax to fetch a new img url every 5 seconds, and then update the image by changing img.src. I tested the same (in IE8, firefox) and it worked without any issues in my development server. But, when I try to put it on production server, many people are complaining that they are not able to see any image at all. Code: if (url_received){
var path = url.substring(url.indexOf("/"));
var img = document.getElementById("testimage");
img.src = "/test/media/" + path;
}
I cannot think of a reason why this is failing for others. Is this due to any security issues? If someone helps me out, I would be very thankful. Hi - I am updating a site for a friend as the original designer has gone missing.. I am no developer by any means but know basic html etc.. I want to change a link in the drop down menu.js file, have opened it in my text editor and changed the link that needs changing to a diff page but it isn't updating on the site - arghhh!! I have notice at the top of the page it has: // QuickMenu Pro, Copyright (c) 1998 - 2003, OpenCube Inc. - http://www.opencube.com does this have anything to do with it? I can't find anything on google - any advice is greatly appreciated. Thanks Hello. I'm creating a simple auto updating script based on PHP and using jQuery to set the interval to 1000 miliseconds. It works in FireFox, as the only one I've tested so far, but in Internet Explorer (Version 7 right now, didn't test others) it just freezes and doesn't auto update. Doesn't auto update either if I refresh the page, so something's messed up here. I'm using the same way of auto updating on other things, such as a chat-page - works on those in all browsers, so I'm kinda on a lost track here. Here's the JavaScript/jQuery: Code: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
function loadContent() {
$('#count').load('counter.php', function() {
setTimeout("loadContent()", 1000);
});
return false;
}
$(loadContent);
And this is what I put on the body of the page: Code: <div id="count"></div> Can anyone see what my problem is? And any workarounds for this? Hi I am making a PC customization website, And I need help wit hthe inputs where you select the parts for the PC. Anyway, I need help for self updating inputs, Like if a user was to select a socket 775 processor, The form would automatically update the motherboard field from --Select a processor-- to a list of socket 775 motherboards. I am quite new at javascript I have never attempted to do anything like this myself, Although I don't know if this would need some PHP in here as well Anyway thanks in advance, Gergy Hi, i have an input value array for customer ids, i also need to make a copy of that array into another input element on submit to use for another process. So far here is what i have come up with regarding the js the current html is this Code:
<!-- original input -->
<input id="cb<?php echo $i;?>" name="cid[]" value="<?php echo $commissions[$i]['id'];?>" onclick="isChecked(this.checked);" type="checkbox" />
<!-- this is new html input which is outside the $i loop that i need a copy of cid[] stored on submit
<input type="hidden" name="ids[]" onsubmit="valueTovalue();" />
<!-- here is the js so far -->
<script type="text/javascript">
function valueTovalue()
{
var valin = document.adminForm.cid.value; //cid is the array cid[]
document.adminForm.ids.value = valin; //copy the array to the new input element array ids
}
</script>
so basically if they click 1 cid then ids will also show 1, if they click all cid then ids will show all as well. will that work the way i have it, am i even close here.. thanks update: what i have seems to work fine for text values or string values but not for arrays, what am i missing that it wont copy an array? Array ( [cid] => Array ( [0] => 1 ) [task] => remarksonly [remark] => hhhyyy [boxchecked] => 1 [ids] => Array ( [0] => ) ) am i getting closer lol Code:
function valueTovalue()
{
var valin = cid.concat;
document.adminForm.ids.value = valin.concat;
return(true);
this has to be close i hope Code: document.adminForm.ids.value = [].concat(document.adminForm.cid); Hi, I've been searching for a good tut on modal boxs for a while where they open in middle of screen like facebook boxs & i want to have one where you use onClick function from href link. example: <a href="#" onclick="'files/delete.php?postId=$post['id']','modal_box'">Delete</a> and so on with other things. Can anyone help. Thanks. Hello, I have a drop down box, which display an images. It is also saved through a cookie on what option you leave it on. Is there a way you can make it so there are several drop downs on the same page that will also display images corresponding to the option chosen?

function linkrotate(which){
var mylinks=new Array()
//add in more links if you want (ie:mylinks[3]=...)
mylinks[0]="http://www.google.com"
mylinks[1]="http://www.ebay.com"
mylinks[2]="http://www.yahoo.com"
window.location=mylinks[which]
}
function showimage()
