JavaScript - When User Hits Checkbox Enter Text In Text Box
Hi. I have developed a form all working fine but am struggling on the following.
I need a checkbox for an item, when the checkbox is true the user can enter text in a text box, only if the checkbox is ticked. I have numerous items I need for this. Hope someone can help. Thanks Similar TutorialsNeed help with my text box. I want to make it so if i have several text boxes only one number can be entered once. So if i type the number 15 in the first text box and type 15 in the second text box an error will occur saying you cant enter the same number twice. Any idea how to do this? Code:
<html>
<head>
<title>Untitled Document</title>
<script>
function checkForInvalid(obj) {
obj.value = obj.value.replace(/[^0-9\-]|(-{2,})/gi, (RegExp.$1.indexOf("-") > -1) ? "-" : "");
}
</script>
</head>
<body>
<form name="myForm">
<input type="text" name="one" onkeyup="checkForInvalid(this)">
<br>
<input type="text" name="two" onkeyup="checkForInvalid(this)">
<br>
<input type="text" name="three" onkeyup="checkForInvalid(this)">
</form>

Thanks 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! well title says it all i have a search form, and the default value is "enter text here" when the user click the submit button, i would like to check if the value of my text input is "enter text here" and if it is, then don't submit the form (popup a warning or something) how can i do that? thanks a lot! I have a small form that I'm working on for a client. They want a form that their potential leads can fill out and then hit 'calculate rate'. Once this is done, the results should display on another page with a short summary of what their quote will be as well as some of the other information they filled out. It should also send an email to my client displaying the information that their lead just filled out. My only problem is I am not sure how to go about the calculation part. I know I would have to do an onSubmit, but how would I hide that calculation and then receive that number on another page. Here is the javascript for that form: Code: /*

If you look at the bottom you can see where the Function that Calculates everything is. Right now it calculates onClick. I just want it to calculate after the user has filled out the form completely and display that calculation on another page along with the rest of the information they inputted. I have a very small script that simply displays a search box and redirects a user to a URL if they enter 29401 or 29455, else they go to a default page. The script works fine, but I cannot figure out how to make value="enter a zip code" in the input box so that it disappears when you click in the box. I also can't get the form to submit by pressing enter, you have to click "check". I can get all this working in straight HTML but the same won't work w/ javascript. Any help please? <SCRIPT LANGUAGE="JavaScript"> function zipValidate(){ val = document.zipForm.zip.value; switch(val){ case "29401": case "29455": document.location = 'http://www.gohere.com'; break; default: document.location = 'http://www.or-go-here.com'; break; } } </SCRIPT> <form name="zipForm" id="zipForm" method="post" action=""> <input name="zip" type="text" id="zip" maxlength="5" /> <input name="zipButton" type="button" id="zipButton" value="Check" onclick="zipValidate()" /> </form> 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')" /> Hi, may I ask how do you display a line or a sentence when you click the checkbox? Here is my validation script from dreamweaver i also have it in php for server side. But I trying to get a checkbox to make a text field required when you select it. Right now I have it so when you hit submit whether the text field is filled out or whether the checkbox is selected or not the error message comes up no matter what i do please help. the link to the page is http://www.mark-10.com/inquiries2 Code: function validateCheckbox() {

As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page. For Example: Input- 512 Output - Austin, TX The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen. Thanks! Hey guys, I just joined the forums (literally) and just started coding (mainly with CSS and HTML) about 3-4 weeks ago. I'd really like to get into JavaScript to make cool things happen on my website. With that being said, I've come up with a pretty cool idea but am not sure how to go about my problem. Enough with the chit chat. What I'm trying to do is add text to a user's input. For instance, if they write "Hello", the function should automatically add "World" to the output. I'd ideally like for the output to be searched on Google (think search engine) with the results displayed on a new page. Thanks in advance for any help! Hey everyone, I've looked around quite a bit and can't seem to find anything but I was wondering if there is some open source software offering a text editor/input field similar to the one used on this forum when submitting a comment or thread? Where you can click a bold button or Italic button or URL button to structure it? Thanks Josh What am I doing wrong here? I am trying to make it where the user can name the link whatever he/she wants.... I think it might be this part... links[i] = name.linkPosition.value; Where linkPosition is a variable. Can I do this? Or is there another way? Code:
<div id="navBar">
<ul>
<li><a href="#" id="link0"><script>document.write(links[0]);</script></a></li>
<li><a href="#" id="link1"><script>document.write(links[1]);</script></a></li>
<li><a href="#" id="link2"><script>document.write(links[2]);</script></a></li>
<li><a href="#" id="link3"><script>document.write(links[3]);</script></a></li>
<li><a href="#" id="link4"><script>document.write(links[4]);</script></a></li>
</ul>
</div><!--end navBar -->
<form>
<label style="color: #FFF;">Change name of links! You can only change them once!</label><br />
<input type="text" class="customLink" size="15" name="link0" onblur="this.value=removeSpaces(this.value);" maxlength="8"/>

</form>
Code: <script>
var links = new Array("home", "portfolio", "stuff", "about me", "contact");
function replaceLinks(name){
for (var i=0; i<=4; i++) {
var linkPosition = "link"+i;
links[i] = name.linkPosition.value;
changeLink(i);
}
}
function changeLink(number) {
document.getElementById("link"+number).innerHTML="<span style=\"text-transform: capitalize;\">" + links[number] + "</span>";
}
</script>
ANY HELP WOULD BE AWESOME!!! I just replaced the functions to look like this... Code: function replaceLinks(name){
for (var i=0; i<=4; i++) {
links[i] = name.linker+i.value;
changeLink(i);
}
}
function changeLink(linkNumber) {
document.getElementById("link"+linkNumber).innerHTML="<span style=\"text-transform: capitalize;\">" + links[linkNumber] + "</span>";
}
Now the links are updating but I get NaN for each link. Hi all, Could someone please tell me how to properly add some text content before and after a user's selection? I am working with the TinyMCE editor, and I can get the following from it: * User's selection as a W3C compatible range * User's selection as a browser selection object * User's selection as a node (element) that encompasses the user's selection I also need the user's selection to remain selected after being wrapped. I've looked all over the web and could find nothing (except running into my OWN previous questions about this). Here's an example of what I'm trying to do: First line is original text, second line a part is selected, third line the selection is wrapped and the selection remains selected. I will greatly appreciate some help here. I've been asking everywhere and nobody seems to know (or they don't bother to answer). Thanks! -- Roger Hello, I have this search box form with 2 select boxes : Code: <form action="search.php" method="get"> <select name="RingType"> <option value="Nose">Nose</option> <option value="Toe">Toe</option> <option value="Belly">Belly</option> </select> <select name="NecklaceType"> <option value="gold">Gold</option> <option value="diamond">diamond</option> <option value="pearl">pearl</option> </select> <input type="text" size="60" name="keywords" /> <input class="submit" type="submit" value="Search" /> </form> For example, when a visitor selects "Belly" RingType, I want "Belly Ring" to appear in the search box. and when the visitor selects "pearl" NecklaceType, I want "pearl necklace" to appear in the search box. if the visitor first selects "Belly" RingType, and then selects "pearl" NecklaceType, I want "Belly Ring pearl necklace" to appear in the search box. After making his selections in the search box, if he types something in the search box, it should add to what is already there in the search box. Or, if he first types something in the search box for example, "jewelry" and then selects "pearl" in the necklacetype select box, the search box should show : "jewelry pearl necklace" Can you please show how to do this ? Thanks a lot. Is it possible to dynamically change the value of text on a page as the user types into a text box? E.g. like: You Are Typing: <script> var keyword = document.getElementById('string'); document.write(keyword); </script> Or I could probably insert it into a function and loop it over and over again or is there a better way? Yes - I need a script that will validate user input against a text file - exactly like the one in the left sidebar at http://www.oilpatchfuel.com/Pages/Welcome.aspx titled "Delivery Area". Thanks! I am trying to use a user defined function and text area for a project, but nothing is showing up in the text area when i click the button. Code: <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

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 |
