JavaScript - Debugging Mad Libs, Accessing Text From Input Boxes
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);" /> Similar TutorialsHello 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 Hello, I have a simple form with simple validation. I am just playing around a bit with forms and don't really have concrete knowledge. What I have done is created a form. Asking for first name, last name, age and email. When the user clicks the submit button I want 2 functions to run, the first checking the input is correct and also making sure all fields have a value. Once everything is checked and is O.K I want to go into another function which sends all this information to an array one by one. I am having difficulty accessing each individual input tag. I could achieve what I want to do, but it will take double the lines of code because each input has a different 'name'. So, what I am trying to do is access the input tags the same as you would do an array. Here is my code: HTML: Code: <form name="regForm" id="form"> <fieldset> <legend>Real Heroes - Registration Form</legend> <p>First Name:<input type="text" size="30" maxlength="20" name="txtFirstName" /></p> <p>Last Name:<input type="text" size="30" maxlength="20" name="txtLastName" /></p> <p>Age:<input type="text" size="30" maxlength="3" name="txtAge" /></p> <p>Email Address:<input type="text" size="30" maxlength="50" name="email" /></p> <p><input type="button" value="Submit Registration" name="butChkForm" onclick="callFuncs_onclick()" /> <input type="reset" value="Reset" name="resetForm" /></p> </fieldset> </form> JavaScript: Code: //CALLING THE FORM SCRIPTS//
function callFuncs_onclick()
{
chkForm_onclick();
creatingDatabase_onclick();
}
//**************FORM VALIDATION***************//
function chkForm_onclick()
{
var theForm = document.regForm;
if (theForm.txtFirstName.value == "" || theForm.txtLastName.value == "" || theForm.txtAge.value == ""
|| theForm.email.value == "")
{
alert("Please complete all of the form.");
if (theForm.txtFirstName.value == "")
{
theForm.txtFirstName.focus();
}
if (theForm.txtLastName.value == "")
{
theForm.txtLastName.focus();
}
if (theForm.txtAge.value == "")
{
theForm.txtAge.focus();
}
if (theForm.email.value == "")
{
theForm.email.focus();
}
}
else if (isNaN(theForm.txtAge.value))
{
alert("That is not valid input for this field. Please re-enter your age.");
theForm.txtAge.focus();
}
else
{
alert("Thank you for completing the form, " + theForm.txtFirstName.value);
}
}
function creatingDatabase_onclick()
{
var form = document.regForm;
var index = form.input[0].value;
alert(index);
}
I'm not quite sure where I am going wrong. Please note that these functions really labour the point, I know I have way too many lines of code but I am still very amateur with JS. Thank you for any help/information. Kind Regards, LC. Hi, I'm struggling with all this DOM stuff so I hope someone can help. I have a form with multiple input fields and I'm trying to identify the specific input field that is in focus so that I can display a relevant status bar message. I have a message array with various entries in it and I'm calling a showStatus() function with an onfocus function from the form itself e.g. The code in the input form = Code: <input type="text" name="first" size="31" maxlength="20" class="entry" onfocus="showStatus()"/> The showStatus() function so far is = Code: function showStatus()
{
var message = ['Please provide your First Name.',
plus loads of other properley formatted status messages......]
var x=document.getElementById().focus();
window.status = message[x];
}
I'd like to access the array variable of the item that is in focus not only for the message but also for an onblur function to validate input. Any ideas? My thanks R 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! I 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 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? 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;
}
}
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. 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 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. I've looked all over google but can't seem to find this out. How do you make it so you have 2 text boxes beside each other where you type (for example) 1 character in the first, and it flows into the next (without the need for pressing tab or whatever) I'm talking about the sort of thing you get when entering a software key Hi, I'm a javascript noob, and I am doing a project for CS. I got the page to look how it is supposed to, but it does not work correctly. The input boxes should display a number between 1-4 in the output boxes, but the box displays [object HTMLInputElement] instead. And the buttons all perform their task to one output box, not their own output box. Sorry if that was confusing.

I have too much text in some case to appear in the text box, so i wanted to find some code so i can select different numbers for pages so i can display the information on different pages. Is this possible. Thanks hello, I have a problem changing the value of multiple text boxes, My page contain one text box named "price" and i need to set the value of this box to all other text boxes in the page which they attribute is <input type="text" value="" name="product[xxxx]" id="product"/> xxxx = random number the page may contain only one text box id=product or more i have tried the following code but it only works with multiple text boxes and doesn't work if the page have one text box Code: var price = document.getElementById('price').value;
var allElements = document.form1.product;
var len=allElements.length;
if(allElements.length){
for (i = 0; i < len; i++){
allElements[i].value = price;
}
I'm not a javascript expert so i don't know if this code is the right way to accomplish this. Thank you very much for your help I am trying to pass data from one form to another form using the url i can get it to come up on the next pages url but how do i get it to go to a text box on the new form. is there a way of assigning text boxes. being trying it in javascript and asp even php would like to keep it to javascript but am open minded to just get it to work figured out, sorry
I am doing a website project and I am currently designing product page. I have created the text boxes dynamically(as many boxes as the user wants) and he can drag and drop the text boxes in the page. I need to create a dynamic line from one text boxes to other text boxes and delete the test boxes which the user does not want. I have created the dynamic graphic line. I know the values of the text boxes can be saved using php in the backend. But is there any way the values with the dynamically created boxes(with <div></div> elements, not with the text boxes) with values and graphics line can be saved online and the user when log-in again can retrieve the work that he saved? Can we code this either in javascript/php? Hi guys, I have a form I am working on that has 4 text boxes in it, but I want to change it so that if a Radio button is selected it makes the 4th text box disappear, but still gives it a value of "0" when the form is submitted. Is this possible with Javascript? Here is what it looks like so far - Code: <FORM><table id='table_columns'>
<tr>
<td colspan="2" align="center">3 Columns <input name="3columns" type="radio" value="3columns"> 4 Columns <input name="4columns" type="radio" value="3columns"></td></tr><tr>
<td align="right"><p>Column 1</p></td>
<td align="left"><input class="txt" size="2" maxlength="2" name="WIDTH1" size="20" Title="Insert the desired width" value="25" /></td>
</tr>
<tr>
<td align="right"><p>Column 2</p></td>
<td align="left"><input class="txt" size="2" maxlength="2" name="WIDTH2" size="20" Title="Insert the desired width" value="25" /></td>
</tr>
<tr>
<td align="right"><p>Column 3</p></td>
<td align="left"><input class="txt" size="2" maxlength="2" name="WIDTH3" size="20" Title="Insert the desired width" value="25" /></td>
</tr>
<tr>
<td align="right"><p>Column 4</p></td>
<td align="left"><input class="txt" size="2" maxlength="2" name="WIDTH4" size="20" Title="Insert the desired width" value="25" /></td>
</tr>
</table>
<br />
<input type="button" value="Save" Title="Save these Settings" onClick="updateSettings('COLUMNS');" /></FORM>
If 3 Columns, WIDTH4 is not viewed and defaults to "0". If 4 Columns, all are visible and the number is then optional. Would love some assistance with this as my coding skills are pretty limited and my fingers have gone numb trying to google an answer. I have been using just basic text lately and now convert them to smiles when it is ECHO'd on the page later on when the page is viewed again. but with to know how to insert them by clicking the images.
