JavaScript - Create New Input Text On Focus.
I tried to create a new text input once the last text box gets focus. But I cant even type in them because every time it gets focus a new text input is created! I really dunno what to do.
Code: <html>
<head>
<script type="text/javascript">
function getTB(field)
{
var i = document.getElementById("f1").length + 1;
var cmd = "<input type=text name = "+ i + " onfocus=getTB() value = " + i + ">";
document.getElementById('f1').innerHTML = document.getElementById('f1').innerHTML + cmd;
document.getElementById(i-2).focus();
}
</script>
</head>
<body>
<form id ="f1">
<input type ="text" value ="hello" name="1" onFocus ="getTB(this)">
</form>
</body>
</html>
how to modify so not every time a new text input created when tried to type in? Similar TutorialsHello everybody I have a page where I have several input text fields (the number of fields is variable), the input text fields are disable , only the first one is enable, as the user goes filling out the text fields, the next text field becomes available, each time the user fills out an input text field, the form is submitted. As I said, the number of text fields is variable, some times I have only one and other time I can have 7. I would like to create a javaScript function to put the next available text field ready to star writing, without having to click in the text field first. The id of my form is "reports" , the id of the table is,"run_params" and the id of my input texts is "inputp". I am using JSF, the HTML output generated for each field is id="reports:run_params:1:input" , the number 1 indicated that is the first input text, this number can go from 1 to 20. I have tried to create a code where I can read how many input fields I have and then create a loop that checks all of them and search for the field that is enable and empty, and put that field on focus. But so far my code doesn't work. I don't have too much experience with javaScript and I already have tried many different ideas, without success, I have not idea how to achieve this objective, because I don't know very well javascript's capabilities, so I don't know what it is possible and what it is not. Any help????!!! Thanks in advance Hi, Because I'm using an asp script to submit this form, I cannot do a validation on the submit and so have chosen to do the validation with the onblur and the onmouseout functions. The validation works well for the checking the first input, id CommenterName. If it's blank, the alert displays and then the cursor is moved to the email check. When the alert is dismissed the focus returns to the first input, but, and this is the problem, returning to the first input, triggers the second alert. How do I return the focus to the first field without triggering the next alert? Changing the order of the inputs in not an option. Code: function checkCompletitionName(){
if (document.getElementById("CommenterName").value.length == 0)
{
document.getElementById("CommenterName").style.backgroundColor = "#efefef";
alert("Please type your name.");
document.getElementById("CommenterName").focus();
return;
}
else
{
document.getElementById("CommenterName").style.backgroundColor = "white";
}
}
function checkCompletitionEmail(){
if (document.getElementById("Email").value.length == 0 || (document.getElementById("Email").value.search("@") == -1 || document.getElementById("Email").value.search("[.*]") == -1))
{
document.getElementById("Email").style.backgroundColor = "#efefef";
alert("Please check the email address for errors.");
return;
}
else
{
document.getElementById("Email").style.backgroundColor = "white";
}
}
function checkCompletitionComment(){
if (document.getElementById("Comment").value.length == 0)
{
document.getElementById("Comment").style.backgroundColor = "#efefef";
alert("Please type your comment.");
return;
document.getElementById("Comment").focus();
}
else
{
document.getElementById("Comment").style.backgroundColor = "white";
}
}

Thanks! But now for the problem... I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax. I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income. Any ideas? Thanks in advance. Code: <script language="javascript" type="text/javascript">

Hi I'm trying to write a data checking function that after it completes should return the focus to the text box that was checked and highlight everything in it IF the value was unacceptable. Here is the function: Code: <script type="text/javascript">
function chkValidity(numToCheck)
{
if (isNaN(numToCheck) == true || numToCheck < 0)
{
alert("Please enter a number greater than zero");
numToCheck.focus()
numToCheck.select()
return false
}
}
</script>
And here are the lines of code that would call the function: Code: <input type="text" name="numBedrooms" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaBedrooms" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="numLivAreas" size="2" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaLivAreas" size="3" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="numServAreas" size="2" maxlength="3" onblur="return chkValidity(this)" /> <input type="text" name="areaServArea" size="3" maxlength="3" onblur="return chkValidity(this)" /> What I find happens is that the data checking works and the error mesage displays, but the focus does not return to the text box. Any ideas? Regards Jenny Hi.. I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php
error_reporting(0);
date_default_timezone_set("Asia/Singapore"); //set the time zone
$con = mysql_connect('localhost', 'root','');
if (!$con) {
echo 'failed';
die();
}
mysql_select_db("mes", $con);
?>

Hi, I am trying to implement something like a javascript that can click and focus the Status Update Box on Facebook. Till now, I have nothing in hand that can perform the task so I thought about a javascript that can do it. I am not even a newbie to javascript but I know that it can perform various complicated tasks on client side. Can anyone here tell me how do I click the Status Update box and set it to focused by a javascript so that when I start typing the Status box receive the text ? Thanks Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John Hi I'm banging my head against this problem and I'd really appreciate some help. I think the problem is cause by my lack of understanding of how the browser (firefox 3.6.3) handles focus. A simplified version of my problem is: I've defined the function Code: function two_focus()
{
document.getElementById("two").blur();
alert("hello");
}
then in the body I have the form with two text boxes Code: <input id="one" type="text"><input id="two" type="text" onfocus="two_focus();"> When the page is loaded and I click in the second textbox I get the alert, all well and good. I OK the alert box, but when I click on box 1, or anywhere on the page for that matter, the function is called and the alert comes up. I just don't understand why the focus is being returned to the second box when I click anywhere in the browser window. Any comments will be gratefully received. 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've got a calculator/quotation script i've made. Once the calculation is complete, i want the user to click a button which will copy some of the field data to new fields for printing. This is fine and i can do easily, however i then want the user to be able to reset the form and do another calculation, click the same button and it copy the new data to new fields too. So in effect you end up with all of your calculations listed somewhere for printing. how would i attempt this? any help appreciated I want to use javasript to create a new html page named from a text field in a form. Then I want to use javasript to copy all of the form fields to the new html page that was created using javascripting. I am creating a user are using a Javascript password login. With most of them the page is the user name or password. So this is why I am looking to do this. I use web 1000 a free host and they will only let me use javascripting. Any info or help would be great thank you
I assumed this is a javascript based text editor because when I turn off javascript it doesn't work. I was wondering how something like this is created. maybe not this exact one, but how would I create something like it. Maybe just a simple editor that changes text size and color.
First, I did this for testing Code: <script type="text/javascript"> <!-- var cururl = window.location.href + "?style=1" document.write(cururl); //--> </script> and it works. It gets the current url of the page and appends ?style=1 then writes out the URL. However getting it as a clickable link is what's stumping me. Code: <script type="text/javascript">
<!--
function goURL()
{
window.location.href + "?style=1"
}
//-->
</script>
<a href="javascript:goURL()">Go There</a>
Doesn't work in my test. As you can probably see, I'm not very well versed in javascript. i am creating a header for a webpage. the header has two text menus (no images). the first menu (menu A) is like this: link 1a / link 2a / link 3a the second menu (menu B) is like this: link 1b link 2b link 3b i would like to use javascript/css to do the following: when you rollover link 1a, three things happen: link 1a changes color, link 1b changes color, and and link 1b adds a line of text (so it reads: link 1b : text 1b) i would also like- and this is where i am having trouble- for the following to happen: when you rollover link 1b, link 1b changes color and adds the additional text, as well as link 1a changes color. it doesn't seem so bad when i write it out here, but i can't figure out how to do it. any help is appreciated. window.onload = initAll; function initAll() { document.getElementById("Message").onfocus = focusHandler; document.getElementById("Message").onblur = blurHandler; } function focusHandler() { document.getElementById("helpYou").innerHTML = "<span class=\"helpMessage\">Hey " + theName + "You should add Lasting Flash to your Facebook!</span>" } function blurHandler() { var helpMessage = document.getElementById("helpYou").innerHTML = ""; } function nameHandler(frm) { var theName = frm.firstName.value; } Quote: When I insert theName variable within the span the code completely does not work. I am accessing a text field when the user enters his name and then a small pop up later that includes the users name when another field is clicked on. 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! Hello all, I am doing a website project and in that currently I am designing a product page. I have to design add values to text boxes and drag and drop the text boxes in the workspace and delete the text boxes the user does not want and have to draw a graphical line between the text boxes which are in order. I have designed and coded everything except the graphical line part. I am a learner in javascript and Can we draw a graphical line dynamically between the text boxes in the webpage? If we can draw, can anyone let me know the tutorial for that so that I can learn and start coding as I have to submit that project soon. Thank you. Currently I have several forms using the input text "field3". I want to know how I can require an HTML input text field to be required WITHOUT having to use the form name in the javascript and without modifying <body>,<form> or <input type="submit">. Also no HTML5 since not all browsers use it (life would be simple if they did since threres a required tag) So here is my form, for example Code: <form name = "test"> <input type="text" name="field1"> <input type="text" name="field2"> <input type="text" name="field3"> <input type="submit"> </form> In otherwords, I can only edit <input type="text" name="field3"> by putting code directly before, in, or after that input field. With this problem, how can I make it required? thank you hi friends , i am on make a dynamic input field creation code , my problem is the entered text(value from "add proposition") is washing away , if i press new "add proposition" my java script is PHP Code: <script language="javascript" type="text/javascript"> function add() { k=document.getElementById("num").innerHTML k=parseInt(k); if(!k) {document.getElementById("num").innerHTML=1; k=1;} else{ document.getElementById("num").innerHTML=k+1; k++; } document.getElementById("cat").innerHTML+="<br />type propositon "+(k)+":<input type=\"text\" name=\"prop"+k+"\">is it answer? <input type=\"checkbox\" name=\"ans"+k+"\"> ignore this one:<input type=\"checkbox\" name=\"ign"+k+"\">" } </script> my html code is PHP Code: <form action="new.php" method="post"> <fieldset> <legend>Add Question & answer:</legend> question type:<br /> True or False:<input type="radio" name="radio" value="t"> Objective:<input type="radio" name="radio" value="o"> Other:<input type="radio" name="radio" value="o"> Quesion:<br /> <textarea name="desc" rows="6" cols="35" ></textarea> <br /> <a href="javascript:add()" ><b>add proposition</b></a> <div id="cat"></div> <div id="num" style="display:none;"></div> <br> <input type="submit" name="submit"> </fieldset> </form> how i solve this problem ? |
