JavaScript - Remove Help Text In Form Field On Click?!
I'm trying to figure out how to both make the text grey and when a user clicks inside a input field remove the helptext.
So far I got this: Code: <input onfocus="this.select()" onblur="this.value=!this.value?'E-mail here':this.value;" name="name" value="E-mail here" type="text"> What this does is allmost correct, but it doesnt remove the predefined text "E-mail here", it just select it all, and then the text is not grey... Can somebody please guide me in the right direction... Thanks in advance! Similar TutorialsHi all, I have a couple of functions, an add error function, if some validation is not met I add a message to a array holding error messages and mark the field red, I have no problem with that piece of code... Code: function addError(errorArray, formObj, message) {
errorArray[errorArray.length] = message;
if (formObj.options != undefined) {
formObj.parentNode.className = "error-field";
} else {
formObj.className = "error-field";
}
}
However I have an issue with the 2nd function, it takes in 2 variables, an id for a div which is displaying the error messages, and the form object, the issue I have is removing the error class. for some reason obj.className = '' fails to remove the class, getting the same object using getElementById() (name and id are the same) however if I construct the removing piece of js code as a String and execute it using eval it works... Code: function clearErrors(errorDivId, vForm) {
var errorDiv = document.getElementById(errorDivId);
errorDiv.innerHTML = "";
errorDiv.style.display = "none";
// remove red boxes
for (i=0; i<vForm.elements.length; i++) {
var obj = vForm.elements[i];
if (obj.type != "button" && obj.type != "hidden") {
if (obj.options != undefined) {
if (obj.parentNode.className == "error-field") {
obj.parentNode.className = "";
}
} else {
if (obj.className == "error-field") {
alert(obj.name);
obj.className == "";
alert(obj.className);
obj = document.getElementById(obj.name);
alert(obj);
obj.className == "";
alert(obj.className);
var jsExecuteCommand = "vForm." + obj.name + ".className = '';";
alert(jsExecuteCommand);
eval(jsExecuteCommand);
alert(obj.className);
}
}
}
}
}
I am so baffled? I have no idea why it won't work can anybody please explain what is happening please? Although I have a work around, I have been banging my head to get to this workaround and I just don't understand why the obj.className = ''; doesn't work. Thanks, Dale I wish to have my form update a text field when a 'add' link or button is clicked, allow for more entries to be added without having the page refresh. but i need to be able to have both the friends name and their number added to the field like so if friends name is say 'jason' and their number is '0987654321' then it will add to the textarea like so. jason [0987654321] this way i should be able to get the data and split it up when the form is send so i can add them in the DB. the part i am stuck on is how to get both fields in the textarea. allowing for more to be added without a refresh. can anyone suggest how they might do this.

I'm having an issue trying to accomplish the following - I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly? Code: <script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
fields = 2;
} else if (fields = 2) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;
} else {
document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;
}
}
</script>
Here is the code in my HTML - Code: <input type="text" name="field1" size="25" /> <span>Field 1.</span> <div id="addedMore"></div> <p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p> Thank you very much. hey guys i dont know if this is javascript or not but i need text in a message body form to instruct people what to write about and then i need it to dissappear once the user clicks into it heres the link, http://www.blusmash.com/test The "Message" text box need to have stuff in it thanks! hi, I have a form with a tick at the end of each formfield: Code: <label>First Name<a href"#">click</a></label> <input class="text-input medium-input" type="text" id="medium-input" name="FirstName" /> <span class="input-notification success png_bg">Successful message</span> the style is currently set to display:none; I would like to use the FadeIn() method on the input-notification class when someone enters some text at the moment I am trying to test using a link to click on: Code: <script>
$("a").click(function () {
$("tab2").fadeIn(3000, function () {
$("span").fadeIn(100);
});
return false;
});
</script>
this doesn't work as I have 2 tabs and the link sends it back to tab1 I am Gururaj. I have written a form in HTML which contains username,lastname,email,password and submit. I have written a javascript to validate this form [validate(username,lastname,email,password)]. On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function.. Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form. In other sense i want to validate individual text field validation of my form. So can anybody help me.It will be very needful to me. In this Form field, when I select the field box that shows "Enter Text" I'd like it so the text disappears, so I can begin typing in a cleared field box. This is the line of code, I believe, that has to do with that function. Any help with having the Enter Text clear upon selecting, will be appreciated: Code: <input autocomplete="off" id="keyword" name="keyword" value="Enter Text" onclick="clickclear(this, 'Enter Text')" onblur="clickrecall(this,'Enter Text')" /> I've been working with this script Code: function changeImage(layer_id, item_id, position) {
var theDiv = document.getElementById(layer_id);
var theImg = (theDiv != null) ? theDiv.firstChild : null;
if (theImg != null) {
// If the item id is 0, then just make the image empty lol
if (item_id == 0)
{
theDiv.parentNode.removeChild(theDiv)
} else {
theImg.setAttribute('src', 'images/' + layer_id + '-' + item_id + '.png');
}
} else {
var toAppend = '<div id="' + layer_id + '" style="position: absolute; z-index: ' + position + ';"><img src="images/' + layer_id + '-' + item_id + '.png" /></div>';
document.getElementById("item-images").innerHTML += toAppend;
}
}
where layer_id, item_id, and position are all defined elsewhere. I've been trying to get the images to append, and then run this line Code: theDiv.parentNode.removeChild(theDiv) when you click on them consecutively(click to append, click again to remove, so three consecutive clicks would have the image shown and four would not), but all I've succeeded at so far is breaking the script's functionality. Help? Hi Guys, Someone please help me how to add new function to remove the field, i have js script function that add new field as follows Code: <script language="javascript">
fields = 0;
function addInput() {
if (fields != 10) {
var htmlText = " <input type='text' name='friends[]' value='' size='auto' maxlength='45' /><br />";
var newElement = document.createElement('div');
newElement.id = 'new_field';
newElement.innerHTML = htmlText;
var fieldsArea = document.getElementById('new_field');
fieldsArea.appendChild(newElement);
fields += 1;
} else {
alert("Only 10 fields allowed.");
document.form.add.disabled=true;
}
}
</script>
but i need some helps to add new functions for removing field, For any suggest and pointer would be appreciate. Hi I have created the following effects on the images seen here http://techavid.com/design/test3.html . You see when you hover and then click on each image, they go from grey to color. When you click on one - the others go grey and the one clicked remains color. That's cool, but now I need the text 1st: Sun for example to display and hide along with its graphic button. The word "Sun," is a link that needs to link out to a URL so it has to be separated from the image effect code. Here code I have now.... Code:
<style type="text/css" media="screen">

What jquery or javascript code do I need to do this? thanks, chaser I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box. I would like to use onBlur but can't seem to get it to work. Can I do this? Help Hi, I'm hoping this will be an easy one for you experts out there. I am working on a convention registration form. What I'm trying to do is have the text "50.00" pop into the COST field when any text (even if it's only one character) is entered into the NAME field. If the text in the NAME field is deleted, the "50.00" should also be deleted. Does anyone have a script that does this? Thanks! I'm trying to set the contact form on http://gspbuzz.com/test to remove the text when a user clicks it. Any idea how I can accomplish this?
Does anyone know how to go about getting a function a bit like fckeditor / ckeditor where when you type a full URL into the 'link to' box it automatically removes the 'http://' part on the fly (i.e. as soon as another character after the initial 'http://' is typed), just leaving the user with www.etc.... in the input? I am trying to build something similar, and am a bit lost going through the fckeditor code! Thanks, Neil Hello, I have tried on many forums, mayby here I will find answer. I have many divs with spans inside(just like it is below-no extra ids,classes for spans:/). Code: [...] <div> <span style="color:red;">a</span> <span style="color:blue;">b</span> <span style="color:white;">c</span> </div> <div> <span style="color:red;">d</span> <span style="color:blue;">a</span> <span style="color:white;">a</span> </div> [...] What I would like to achieve: user selects with mouse "ab", click button(input type=button) which remove style from selected span/spans. Similar behavior like it is in TinyMCE. I'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;
}

Hi im using this to hide and show some text, how do i do to change the text "Show" to hide when i click it and back to "Show" when click it again. Code: <script type="text/javascript">
$(document).ready(function(){
$('.accordion-content').hide();
//toggle the componenet with class accordion
$('.accordion-toggle').click(function(){
//$(this).toggleClass('toggle-accordion-active');
$(this).next('.accordion-content').slideToggle(300);
});
$('#accordion-expand-all').click(function(){
$('.accordion-content').slideToggle(300);
});
});
</script>
Code: <p><a id="accordion-expand-all" href="#">Show</a></p> Hello guys, I'm new to Javascript and my question involves text appearing upon a button click or after a set time. I have the following code: Code: <script type="text/javascript">
function timedMsg()
{
document.write("Timed Messege.");
}
And the button: Code: <form> <input type="button" value="Display timed alertbox!" onClick="timedMsg()" /> </form>[ I guess document.write is not the correct command to use in such situations, since it just replaces the whole page. Which command should I use so that the wanted text appears within the page, without reloading or replacing it? Thanks in advance. I could not find a proper command in my search. Hi there! I need help! Basically, I need to create a sentence and on one of the words the person accessing the site can click the word and it will change to another word and then again to a third word and so on for 5 words then it will, on click, return to the 1st word again. like a circle of various words. I've managed to get it to work with 2 words back and forth - but I need it to have multiple states. I need the JS and how to impliment it in the HTML. JS isnt my strong point just yet Please help me! Thanks so so much! follow me on twitter - @robyn_90 |
