JavaScript - Form Field Progress Bar
Hi!
I use the :: Form field Progress Bar from DynamicDrive: Form field Progress Bar Now I trided to change the text when the textarea is full "Limit:100%" to "Your max. characters is reached" I trided it but with no luck. This is the main code.. Code: <script type="text/JavaScript">
function textCounter1(field,counter,maxlimit,linecounter) {
// text width//
var fieldWidth = 137;
var charcnt = field.value.length;
// trim the extra text
if (charcnt > maxlimit) {
field.value = field.value.substring(0, maxlimit);
}
else {
// progress bar percentage
var percentage = parseInt(100 - (( maxlimit - charcnt) * 100)/maxlimit) ;
document.getElementById(counter).style.width = parseInt((fieldWidth*percentage)/100)+"px";
document.getElementById(counter).innerHTML="Limiet: "+percentage+"%"
// color correction on style from CCFFF -> CC0000
setcolor(document.getElementById(counter),percentage,"background-color");
}
}
function setcolor(obj,percentage,prop){
obj.style[prop] = "rgb(80%,"+(100-percentage)+"%,"+(100-percentage)+"%)";
}
</script>
This is the place where the text is set. Code: ((fieldWidth*percentage)/100)+"px"; document.getElementById(counter).innerHTML="Limiet: "+percentage+"%" Help would be highly appreciated ! greetings Jardin Similar TutorialsI've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. Could someone please explain what I am doing wrong? here is my code so far... Note: just for testing purposes I've put return false on everything so it displays a message when everythings ok. Code: ....
<script type="text/javascript">
window.onload = function() {
document.forms[0].username.focus();
}
function validate(form)
{
var form = document.getElementById("reg");
var e = document.getElementById("error");
e.style.background = "red";
for(var i = 0; i < form.elements.length; i++)
{
var el = form.elements[i];
if(el.type == "text" || el.type == "password")
{
if(el.value == "")
{
e.innerHTML = "Please fill in all fields!";
el.style.border = "1px solid red";
el.focus();
return false;
} else {
el.style.border = "1px solid green";
return false;
}
}
}
var un = form.username;
un.value = un.value.replace(/^\s+|\s+$/g,"");
if((un.value.length < 3)|| (/[^a-z0-9\_]/gi.test(un.value)))
{
e.innerHTML = "Only letters,numbers and the underscore are allowed (no spaces) - 3-16 characters";
un.focus();
return false;
}
var pw = form.password;
pw.value = pw.value.replace(/^\s+|\s+$/g,"");
if((pw.value.length < 3) || (/[^a-z0-9]/gi.test(pw.value)))
{
e.innerHTML = "Only letters and numbers are allowed (no spaces) - 3-16 characters";
pw.focus();
return false;
}
e.innerHTML = "You filled in all the fields, well done!";
e.style.background = "green";
return false;
}

Hello, can this upload progress windowsbar be made to close or stop at 100%? In the upload page the javascript code: Code: <script language="JavaScript">
function input(ok)
{
var M1=ok.upload_author.value;
if (M1=="") {
alert("Author is empty!");
return false;
}
M1=ok.upload_title.value;
if (M1=="") {
//alert("File Description is empty!");
//return false;
}
if (ok.UploadedFile.value=="") {
alert("File is empty!");
return false;
}
var sCheckType="%checktype";
if(sCheckType=="1")
{
M1=ok.UploadedFile.value.toLowerCase();
var pos=M1.lastIndexOf('.',M1.length);
var sExt;
if(pos>-1)
sExt=M1.substr(pos+1);
var sType="%filetype";
pos=sType.indexOf(sExt);
if(pos>-1)
{
alert("This type of file cannot be uploaded!");
return false;
}
}
ok.uploadid.value=Math.round(Math.random()*100000000);
return true;
}
function onstopupload() {
if(document.post.uploadid.value=="") return;
window.("uploadstop.ghp?uploadid="+document.post.uploadid.value+"&vfolder="+document.tempform.vfoldername.value) ;
}
function onshowprogress() {
if(document.post.uploadid.value=="") return;
window("showprogress.ghp?uploadid="+document.post.uploadid.value+"&vfolder="+document.tempform.vfoldername.value) ;
}
</script>
Then the "Show progress" button which on clik opens in a new window. Code: <input name="Upload" type="submit" class=button value="Upload">
</font>
<input name="stopupload" type="button" class=button id="stopupload" value="Stop" onClick="onstopupload()">
<input name="showprogress" type="button" class=button id="showprogress" value="Show upload progress" onClick="onshowprogress()">
And here;s the code from the Progress window. Code: <strong>Incarcare %filename...
<br>
%progress%
<br>
<table width="50%" border=1 align="center" cellpadding=0 cellspacing=0>
<tr>
<td bgcolor="#FF0000" width="%used%" height=15 style="border:0"> </td>
<td bgcolor=white width="%left%" height=15 style="border:0"> </td>
</tr>
</table>
<br>
<a href="showprogress.ghp?uploadid=%uploadid&vfolder=%vfolder">Actualizeaza</a>
<a href="uploadstop.ghp?uploadid=%uploadid&vfolder=%vfolder">Stop</a>
Plese if anyone knows how to resolve this to pop-up in a window and when it reachis 100% to stop redirecting, or to close it self or by user. Thanks in advance. Cira Marius Hey guys! I have a progress bar written in javascript. Its pretty simple, consisting of a couple divs, where the inside one grows with the given percentage. Anyways, the problem we are having is that sometimes the percentage that is dynamically calculated is over 100% (we are using it as an job completion progress bar, so if more hours are spent than estimated the bar will be over 100%. I guess thats fine, except the inside div goes right off the container and keeps growing. Can we make the inside div max out at 100% somehow? Hoping someone can help me out with this, im not sure how this can be done! I should add that the original script with example I found he alpinemeadow.com/stitchery/weblog/HTML-morsels.html Here is the original code: Code: <script language="javascript">
function drawPercentBar(width, percent, color, background)
{var pixels = width * (percent / 100);
if (!background) { background = "none"; }
document.write("<div style=\"position: relative; line-height: 1em; background-color: "
+ background + "; border: 1px solid #979797; width: "
+ width + "px\">");
document.write("<div style=\"height: 1.5em; width: " + pixels + "px; background-color: "
+ color + ";\"></div>");
document.write("<div style=\"position: absolute; text-align: center; padding-top: .25em; width: "
+ width + "px; top: 0; left: 0\">" + percent + "%</div>");
document.write("</div>"); }
</script>
Called for he Code: <script language="javascript">drawPercentBar(171, <%=totaltotal/EstHours*100%>, '#aadba2', '#F2F2F2'); </script> How can I add a form field value to a url. I tried the below but it no work. Code: href="index2.php?q=4&id=+document.theForm.lists.value+&picklist" All, Say I have a four part process to add something to my website. I'd like to have a bar at the top of my page (if you need an example, something simliar to FedEx to show where you package is along the way) that will get updated upon each page move so the user knows how far along they are in the process and how much farther they have to go? Any type of tutorials or ideas (whether it's PHP and jQuery or any other combination) I'd greatly appreciate them. Thanks in advance for any guidance. Thanks. Hi there, I have a html form, and I need it so that when a user clicks a button, it adds a field into the form. I also need it to write <td></td> around the new field, and I need it to write this in a specific part row of a table. How would I go about doing this? I've tried searching for the past two hours, but no luck. Many thanks, I appreciate it, Jason I have a form which has various fields which are arrays (so the name of a field may be myField[]). The reason for this is that the form has add buttons to add another field or fields for the purpose of entering another email address, etc., to send invitations and do other things. The problem that I am running into is how to access the individual fields in an array of fields inside javascript to do form validation. So if I have an email address field name emailAddress[], and using the add button, the user of my site adds 3 other copies of the emailAddress[] field, I want to then do form validation onSubmit to ensure those email address are valid using standard procedures. However, inside the javascript code, how do I access the individual fields that make up emailAddress[]? I just cannot find anywhere online the proper way to get at these values. If anyone can help me, I would greatly appreciate it. Happy Holidays Is there a way to give an input or textarea field the focus and set the focus to begin right at the end of the current text in the field?
I need to learn how to clear form fields when a user clicks on them. Here is the site in question: http://www.yourvancouvermortgagebroker.ca/apply They used to work, but then I changed the field value and now it doesn't work on some of the fields (whichever ones I changed). Here is a link to the .js file: http://www.yourvancouvermortgagebroker.ca/js/apply.js function checkValidFormInput() { if (document.getElementsByName('customerName').value != '') { document.getElementById('customerNameImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">'; } else { document.getElementById('customerNameImg').innerHTML = '<img alt="Invalid" src="images/redX.png">'; } if (document.getElementsByName('customerEmail').length > 0) { document.getElementById('customerEmailImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">'; } else { document.getElementById('customerEmailImg').innerHTML = '<img alt="Invalid" src="images/redX.png">'; } } I want to update the variables in the progress bar HTML5 has to offer. Here is the function I have so far (It has been modified and shortened for the means of this post): Code: function calcProgress()
{
var num1 = Number(document.form.num1.value);
var num2 = Number(document.form.num2.value);
Number(document.form.progress.value) = num1
Number(document.form.progress.max) = num2;
}
This is the form: Code: <form name="form"> <input name="num1" onChange="calcProgress()" type="text" value="0" /> / <input name="num2" type="text" value="0" onChange="calcProgress()" size="1"> <br> <progress name="progress" id="progress" min="0" value="0" max=""></progress> </form> Hi, I have searched the web for many tools to upload a file and shows it progress, but they all seem to use, flash, codebehindfiles, php etc. I was looking for one that used pure Javascript was wondering if anyone could help? Thanks Marcel. I'm in the process of building a blog that will be using some pretty neat jQuery effects to spotlight its content. One thing I've been looking at doing is trying to lessen the amount of different pages the visitor has to load by using things like sliders and accordions to hide and display content. Overall I'm not concerned that the pages will take more than 3-4 seconds on any decent connection to load, however I was thinking about visitors who are potentially running slower connections. To avoid losing those slower-connected users I've been looking for a way to display a page loader, much like what you see on flash websites, except completely without flash. I was hoping there might be some AJAX algorithm or jQuery function I wasn't aware of that might help me accomplish this. If anyone could point me in the direction of a tutorial, I'd really appreciate it! Thanks in advance. Greetings, I'm working on a php/mysql app that has multiple tabs with multiple form fields. I am trying to incorporate a javascript form field detection function that alerts the user that they have not submitted their changes if they try to navigate away. The detection works as designed, but the problem I am having is when the form is submitted, the script senses an unload and still fires the alert. The form submits to itself and updates the database and then reloads the page with the new values. Is there a way to have the script ignore the forms submit url and skip the form check? Here is the code ( NOT mine, found it somewhere else.) Code: <script language="javascript">
var ids = new Array('description');
var values = new Array('<?php echo $detail['description']; ?>');
function populateArrays() {
// assign the default values to the items in the values array
for (var i = 0; i < ids.length; i++) {
var elem = document.getElementById(ids[i]);
if (elem)
if (elem.type == 'checkbox' || elem.type == 'radio')
values[i] = elem.checked;
else
values[i] = elem.value;
}
}
var needToConfirm = true;
window.onbeforeunload = confirmExit;
function confirmExit() {
if (needToConfirm) {
// check to see if any changes to the data entry fields have been made
for (var i = 0; i < values.length; i++) {
var elem = document.getElementById(ids[i]);
if (elem)
if ((elem.type == 'checkbox' || elem.type == 'radio') && values[i] != elem.checked)
return "Your changes have not been saved. Are you sure you want to leave?";
else if (!(elem.type == 'checkbox' || elem.type == 'radio') && elem.value != values[i])
return "Your changes have not been saved. Are you sure you want to leave?";
}
// no changes - return nothing
}
}
</script>
The url of the page is "edit.php?&mode=edit&t=2&id=284&cn=2009-002" The only detectable change to the query string would be the 't' variable. Basically what I want to do is have the script look for a change in the 't' variable and if detected, check the form values for changes. If 't' doesn't change, skip the script completely. Thanks.. Though I know nothing about Javascript, that didn't stop them from assigning me the task of mothballing our Excel spreadsheets and going to fillable .PDF forms. Here's my first of many questions: In one of my fillable PDF forms, I take the numbers (entered by the user) from two or three fields and calculate those placing the answer in a seperate field. Since we work with very large, and very small numbers, I want the number in the answer field to be displayed in scientific notation. Adobe Acrobat is not very flexible when it comes to selecting a number format, so a script is obviously needed to do the conversion. I've also noticed that Adobe doesn't like the user entering a number in a field in scientific notation. My number calculates out correctly if you enter .000000274 in the field, but does nothing if you enter 2.74E-7. Help with that would also be greatly appreciated. Don Hello, I have several event handlers on my page; one of them doesn't work. I'll post them all here, indicating how they are executed: #1: Works [CODE]<script type="text/javascript"> function combName() { var fname = document.forms[0].fname.value; var lname = document.forms[0].lname.value; document.forms[0].name.value = fname + " " + lname; } </script>[CODE] NOTE: The "lname" field uses "onKeyUp" to make the script run. A hidden field named "name" is populated with the concatenation. #2: Works (this script is too long to post; it is a validation script and runs via the "onSubmit" in the form tag.) #3: Doesn't Work [CODE]<script type="text/javascript"> function combPrograms() { document.forms[0].00N70000002WNax.value = "1st Choice: " + document.forms[0].sf1.value + document.forms[0].alameda1.value + document.forms[0].sanmateo1.value + document.forms[0].marin.value + document.forms[0].cc1.value + "2nd Choice: " + document.forms[0].sf2.value + document.forms[0].alameda2.value + document.forms[0].sanmateo2.value + document.forms[0].marin2.value + document.forms[0].cc2.value; } </script>[CODE] Note: 1. Not all of the values for Choice 1 and Choice 2 are populated. 2. For that reason, one of the later, unrelated text fields in the form has "onKeyUp="combPrograms()" to run the event. 3. A hidden field named 00N70000002WNax is populated with the concatenation. Any help is much appreciated! I have modified a free JS function from he http://www.tangorangers.com/examples...post/index.php To dynamically add text fields to the form. My work-in-progress version is he http://jimpix.co.uk/junk/test/6.html On the form, I have a hidden text field: Code: <input type="hidden" name="hiddenCount" value="" /> What I'd like to do is to increment the hiddenCount each time the "Add" fields button is clicked. This is the button: <input id="add_contact()" onclick="add_contact()" value="Add" type="button"> And this is the JS function: Code: var contact_counter = 0;
function add_contact()
{
if (contact_counter < 9)
{
contact_counter++;
var newFields = document.getElementById('add_contact').cloneNode(true);
newFields.id = 'contact';
newFields.style.display = 'block';
var newField = newFields.childNodes;
for (var i=0;i<newField.length;i++) {
var theName = newField[i].name
if (theName)
newField[i].name = theName + contact_counter;
}
var insertHere = document.getElementById('add_contact');
insertHere.parentNode.insertBefore(newFields,insertHere);
}
}
I'm new to JS. I could just about edit the JS function to slightly modify it from the tangorangers version (I only changed it v. slightly). To somehow increment the value in the hidden field each time the button is pressed is beyond me though! Any advice much appreciated. Thanks Hi everyone, im new to javascript and I have created two forms.. a value will be put in the first field and the second field should display either $20 or $35 depending on the value of the first field. Im doing something wrong here.. but I cant see what. Any help is appreciated. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Distance from Depot</title> </head> <body> <form id="distanceform"> <ul> <li> <label for="Distance from EverWarm Depot">Distance from Depot (km):</label> <input type="text" id="distance" class="large"/> </li> </ul> </form> <input name="Button1" type="button" value="calculate" onclick="deliverycost()"/> <form id="deliverycostform"> <ul> <li> <label for="Delivery Cost" >Delivery Cost:</label> <input type="text" id="deliverycost" class="large"/> </li> </ul> </form> <script> function deliverycost() { /* Here is the delivery cost: less than or equal to twenty kilometres is $20.00 greater than twenty kilometres is $35.00 */ var distance = document.forms["neworder"]["distance"].value; if(distance<20) { document.getElementById('deliverycost').innerHTML="$20"; } else { document.getElementById('deliverycost').innerHTML="$35"; } } </script> </body> </html> |
