JavaScript - Copying The Values In Textboxes
Hi everyone,
Is there a shorter and cleaner way of performing the following: The objective is to get the value/input from the first set of textboxes in the form and copy them to other set of textboxes. Outline of the form is as follows: First set of textboxes Company Address City State Zip Country Select number of users -->1 2 3 User 1 Company Address City State Zip Country User 2 Company Div Address1 Address2 City State Zip Country User 3 Company Address City State Zip Country ============================================= At the moment the code looks like this where (comp,div, addra,addrb,city,state,zip and country) are the name attributes of the first set of text boxes and (comp1.....country1,comp2.....country2, comp3....country3) are the name attributes for the textboxes for user 1,2 and 3 respectively. Code: function compAddress(){
document.form.comp1.value = document.form.comp.value;
document.form.div1.value = document.form.div.value;
document.form.addra1.value = document.form.addra.value;
document.form.addrb1.value = document.form.addrb.value;
document.form.city1.value = document.form.city.value;
document.form.state1.value = document.form.state.value;
document.form.zip1.value = document.form.zip.value;
document.form.country1.value = document.form.country.value;
document.form.comp2.value = document.form.comp.value;
document.form.div2.value = document.form.div.value;
document.form.addra2.value = document.form.addra.value;
document.form.addrb2.value = document.form.addrb.value;
document.form.city2.value = document.form.city.value;
document.form.state2.value = document.form.state.value;
document.form.zip2.value = document.form.zip.value;
document.form.country2.value = document.form.country.value;
document.form.comp3.value = document.form.comp.value;
document.form.div3.value = document.form.div.value;
document.form.addra3.value = document.form.addra.value;
document.form.addrb3.value = document.form.addrb.value;
document.form.city3.value = document.form.city.value;
document.form.state3.value = document.form.state.value;
document.form.zip3.value = document.form.zip.value;
document.form.country3.value = document.form.country.value;
Thanks, Similar TutorialsHi all, I create textboxes dynamically by the following code function addElement() { var contentID = document.getElementById('content'); var newTBDiv = document.createElement('div'); newTBDiv.setAttribute('id','strText'+intTextBox); divname='strText'+intTextBox; newTBDiv.innerHTML = "Text "+intTextBox+": <input type='text' id='divid' +intTextBox name='txtbx[]'/>"; intTextBox = intTextBox + 1; contentID.appendChild(newTBDiv); } It works fine,but i want to get the values and validate it so i use the following code.. var idval=new Array(); for(var i=0;i<intTextBox;i++) { idval[i]=document.getElementById('divid').value; alert(idval[i]); } but it didn`t work out,Any suggestions really helpful. Thankyou. Either I'm having a moment of stupidity, or have completely failed to understand a fundamental aspect of javascript. The code below is jquery, and uses jquery's extend() function, but I don't think that the issue has anything to do with that... does it? Code: $(document).ready(function(){
var obj1 = {
"name": "spud"
,"age": 32
}
var obj2 = obj1;
$.extend(obj2, {"location": "UK"});
console.log(obj1);
});
By my reasoning, obj1 shouldn't have location set. But it does. If this is something peculiar to jquery, then my apologies and I'll go off to the right forum - but is it? Is the line var obj2 = obj1; not making a copy of the original and leaving the original intact? Is it instead making some sort of reference to it? Why is changing the copy having an effect on the original?? G'day, How would I go about copying all the prototype functions AND the constructor from one object into another object, and then call them? Code: function myOriginal() {
alert('Hello');
}
myOriginal.prototype.example = function() {
alert('In example '+this.test);
}
function myNewThing() {
// Copy myOriginal into this object here
this.oldconstructor(); // Should now display "Hello"
this.test = 'from myNewThing';
this.example(); // Should now display "In example myNewThing"
}
I know I can use this.example.call(this), but that's not an acceptable solution. I want to deploy this style over dozens, potentially hundreds of objects. Thanks muchly, Your friend from server-side... Hello, I need your help, I can seem to get this to work. I want to be able to use an IIF to check if a textbox empty ie. IIF(textbox1 = "" || textbox = null, "it is empty","it is not empty") This doesnt seem to be working. Any ideas? - Clueless =? I have 2 textareas, 1 which will be vissible, another that will be hidden. I have a function that mirrors (not in reversed lettering) the first textarea's input to the second. Code: function copy_data(val){
var messageText = document.getElementById(val.id).value
document.getElementById('message').innerHTML = messageText;
}
So that copies from : <textarea name="text_message" rows="4" id="text_message" style="direction:ltr;" onkeyup="copy_data(this)"></textarea><br/> To: <textarea name="message" rows="4" id="message" style="direction:ltr;"></textarea> Then I have another function which when I select text in the "text_message" textarea will apply a tag to it, however I don't want this tag to be vissible in the "text_message" textarea but rather in the "message" textarea. Code: function formatText(el,tag){
var selectedText = document.selection?document.selection.createRange().text:el.value.substring(el.selectionStart,el.selectionEnd);
if(selectedText!=''){
var newText=''+tag+''+selectedText+''+tag+'';
el.value=el.value.replace(selectedText,newText)
}
}
This effects from this checkbox: <input type="checkbox" id="bold1" name="bold1" onclick="formatText(message,'#28D')" checked="checked" > Could anyone please help me, I think I may have missed something somewhere, because it works if I point it back to "text_message" I have 2 text boxes on my page. When the user clicks in one text box, I would like whatever is in there to be copied to the other text box. Is this possible? I have looked into it and onClick seems like it might do it but I can't get it to work. Thanks. Essentially, I have an ASP.net page where I load a record set server side and upload it into a listbox. I'm trying to do all the movement functionalities of the listbox items client side. Specifically, I'm trying to figure out how to copy selected listbox items from one listbox to another -- on button click. I've searched for a while, but every example that I found moves the actual item into another listbox, I just want to copy the selected item to another listbox. I'm very new to JavaScript, so ff someone can provide an example or pseudo code, I would greatly appreciate it. Hi and thanks for your help, I have two text boxes on my page and a third where I would like it to automatically subtract the two any time either one of them is changed. What is the simplest way to do this? Thanks again for your help, Will Hi there...I have an autosuggest that I got from a friend. My question is ... the autosuggest works well on my business textbox - what would the code look like to get it to work on the region textbox (or how do I get it to work on more than one textbox - can I just make a copy of the js file and change stuff)... Here is the html code for the index.html page with two boxes and a submit button... Code: <!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">

<link href="searchfield.css" rel="stylesheet" type="text/css" media="screen" />
<script type="text/javascript" src="searchfield1.js"></script>
</head>
<body>
<form name="searchresults" action="Site/searchresults2.php" method="post" >
<input name="Business" class="textfield_effect" type="text" value="Enter Business Type or Name" size="30" onfocus="if(this.value==this.defaultValue) this.value='';" autocomplete="off"
id="businessquery" />
<input name="Region" class="textfield_effect" type="text" value="Enter Suburb or Postcode" size="30" onfocus="if(this.value==this.defaultValue) this.value='';" autocomplete="off" id="regionquery" />
<input type="submit" class="textfield_button" value="Search"/>
</body>
</html>
and here is the code for the file called searchfield1.js that powers the autosuggest... Code: this.searchfield = function(){
// CONFIG #
// this is id of the search field you want to add this script to.
// You can use your own id just make sure that it matches the search field in your html file.
var id = "businessquery";
// Text you want to set as a default value of your search field.
var defaultText = "Enter Business Type or Name!";
// set to either true or false
// when set to true it will generate search suggestions list for search field based on content of variable below

Many thanks for hints, suggestions and contributions Hi, I have a requirement where, on a link, when the user clicks, the app should copy all browser favorites and write to a db (table that has two columns, one with fav name and one col for the website link). Thoughts on how to get this done ? How can I read the the browser favorites from a javascript ? Thanks, Deepna Hi guys! i would like to ask for your assistance.. i am creating two template for my work.. and i would like to know what is the javascript that in one click i can copy and paste all the details from template #1 to template #2. considering that each field in template 1 will fall into the correct field in template #2.. http://img130.imageshack.us/i/25157983.jpg/ hope to hear from you soon. thanks! you may also email me at janshawn_54@yahoo.com Hi, I have some tickboxes and one is marked Other. So what I would like is when someone put a tick in other, to display 5 textboxes name Other 1 to 5 I presume this is done by javscript, but not sure where to start, can anyone help? Also if possible when they untick it, they disapper, but not a must. Each tickbox is independent from each other. It can also use jQuery or Ajax if that helps i have a form with several headings, then for each heading i have a list of items with a select box filled with numbers. For each heading a maximum of items is allowed, so the user should change the values in the dropdowns and not be allowed to continue until they are less than or equal to their maximum limit. To complicate this, there will be more than one headings on the page, but each one with a different name/id. Eg: Heading 1 Title 1 DROPDOWN1 Title 2 DROPDOWN2 Title 3 DROPDOWN3 So here the max is 10, so the values cannot exceed 10 Heading 2 Title 1a DROPDOWN1 Title 2a DROPDOWN2 Title 3a DROPDOWN3 Title 4a DROPDOWN4 So here the max is 10, so the values cannot exceed 14 thanks Hello, I need your help. I have 2 checkboxes. How would I control one from the other? Eg. [ ] Option A [ ] Option B - If Option A was checked first and, I put a checkmark in option B then Uncheck Option A and leave option B checked. - If Option B was checked and, I put a check mark in Option A then uncheck Option B and leave Option A checked. How would that be written in Javascript, I am totally confused. Any help with this is much and foremost greatly appreciated. Cheers, J Hello, I have an entry form using multiple select boxes as data entry in the upper portion of my page. below i want additional details of the item selected in a table like textboxes by clicking an add button.So whenever i click the add button a new row of text boxes is again created. problem: upon selecting an additional/new item from the select boxes the first row of textboxes doesn't retain it's value it reflects the currently selected values. all the data mentioned above is contained in a single page is it possible? using a classic asp using javascript to do this?please help, i'm really lost..attach is a snopshot of my page... Hi , I have 5 or 6 textboxes and all of them are required ( have required field validators ) .. I want to change their background color to yellow when they are left blank and when the box is filled the backgorund color to white ..Is it possible to do via javascript ..I am a beginer so any help is greatly appreciated I have the following code which adds a dynamically created textbox to a form: Code: function addarow() {
if (count > 5) {return false}
count ++;
addbox = '<input type = "text" name = "txt1" id = "txt1" class = "box">';
document.getElementById("boxes"+count).innerHTML = addbox + "<br>";
}
I am having difficulties in assigning different names/ids to the sequential textboxes, that is "txt"+count to give txt1, txt2 etc. Your assistance will be much appreciated. A child of five would understand this. Send someone to fetch a child of five. Groucho Marx Hello all, I am trying to copy the billing information to be the same as the shipping information when they select the checkbox. Everything seems to work except for the State field which is a drop down. Depending on what country they select, the state field will automatically populate. Does anyone know how I can copy the billing state to be the same as shipping as well? Text file attached. Thanks in advance. Hello! coding forums gals, I am resorting to you for help with a html form that uses javascript to validate data. the form is an invoice for a trip order where the user can select a trip location out of a listbox, a number of people traveling, and where they wish to stay(ex. hotel, tent, etc.) after the user selects one for each category and hits the "add to invoice" button, the fields in the invoice should get filled with the corresponding information. Now my question is how can I write code that will insert information in the next line down and all other lines below if the user wants to schedule more than one trip at a time? basically what logic and programming structure do I need in my function that will know when the first line in the invoice is filled and will add data in the next line down. after I have successfully placed an order, and I want to make another one, how do I get javascript to output data on the second line?

if (myUserName.value == "" || myUserName.value == null) {

// Verifies that the Telephone field value is in the correct format.
var tel = document.getElementById("telephone");
var pos = tel.value.search(/^\(\d{3}\)\d{3}-\d{4}$/);
if (pos != 0) {

// The event handler function
if (chkUser() && chkTelephone()) {
