I need to use a different type of name for a field in a form. does
anyone know how I can access this with this kind of name?
<input type="text" name ="id[txt_3]" size="6" maxlength="6" value="">
now how can I access this name in javascript?
//this doesn't work??
document.form_name.id[txt_3].value
document.form_name.?????????.value
I am having field names in HTML with a period in them for e.g.
<INPUT TYPE='hidden' NAME='cars.toyota.camry' VALUE=དྷK'>
I need to know how to access this field name in Javascript.
I have several fields being updated for a parking structure... The client inputs the number of cars and can immediately see the percentage before updating the database....
The field names always change so I need the JavaScript to be able to pick up the unique field names calculate and place into the total field box...
I found this code online, but I need to do this dynamically for hundreds of lots...
So basically I have a field name and an ID number identifying the 3 related fields...
Here's an example that works for one lot:
<HEAD>
<script type="text/javascript">
<!-- Begin
function startCalc(){
interval = setInterval("calc()",1);
[Code]....
I have a form that generates field names dynamically based on a number selected from a drop-down. For instance, if I select 5 from the drop-down, it will generate 5 fields with the names email1, email2, email3, email4 and email5.
How do I loop through these to determine which ones are empty?
Code:
while (i<=ulimit)
{
emailval = "document.myform.email" + i + ".value";
//alert(emailval);
[Code]....
Have the Javascript function below which takes the name of an input on the form passed as a variable so that 1 function can check many inputs as I have up to 3 fields per form that can accept this data range.
function contact_number_check(formObj,field)
{
var obj = document.forms[formObj];
var regExp = /^([0-9 ])+$/;
alert(field);
[Code]...
Say I have some variables setup like so;
<script type='text/javascript'>
<!--
panelsArray = new Array("form0","form3","form4","form5","blotter");
var blotter = new Array(འ',騦',魒',饼','block','');
var form0 = new Array(餢',ཱི',骹',餑','block','');
var form3 = new Array(鰌',ྀ',馅',飣','block','');
var form4 = new Array(鮵',髧',駨',飶','block','');
var form5 = new Array(Ɔ',Ɔ',魽',饻','block','');
// -->
</script>
and I want to parse the first array and then within that loop I want to get the variable name from the 'outer' array and then reference the contents of the array with that name... I was trying to do the following but it doesn't work, I'm obviously missing something about transmogrifying the text "form0" into a variable name...
for(f=0;f<panelsArray.length;f++) {
thisPanel = panelsArray[f];
alert(thisPanel);
thisPanelWidth = thisPanel[0]
alert(thisPanelWidth);
}
I have an array for of input names. Input1 , input 2 etc. Can I pass the input names in a loop like document.all[input].value="xxxx"
The problem is document.all cannot be used in Safari/firefox, I tried using document.getElementById but my inputs do have any IDs. is there any way of accomplishing thsse.?
I'm trying to make a form where a user can check boxes, and depending on if certain boxes have been checked, other boxes will grey out or un-grey.
What the code does is look at the checkbox name and depending on the family (f), and whether or not the box is a child (c) or a parent (p), the code will grey out certain boxes.
Now that I've sat back and thought about the code, I think there is probably a better way to achieve what I want. Maybe I can specify checkbox names instead of doing the parent child hierarchy that i'm trying. Code:
I am having difficulty using javascript to validate form fields with whitespaces in the element names (ex: First Name, Last Name).
here's a code snippet:
###
function validate(formObj) {
if (document.form1.Payment Method.checked){
do something here...}
###
the problem is that javascript won't read the element "Payment Method" unless i mash the name into one word. (i don't want to do that because i later use the element names to provide a printable customer receipt
i tried using the ascii octal number for a whitespace in the above code (...form1.Payment40Method.checked...), but to no avail.
I have a server-side ASP script that dynamically creates an input form from
a database table. The table contains a field name, the table where values
are stored, type of input control, value for a label, etc.
What I need to do is create a JS validation routine that will check each
control for valid input, regardless of what the control name is. If it is a
"select", it needs to verify the index is > 1. If it is an "input", it needs
to check that it isnt't empty, etc.
Using known fields, I usually do something like this (page name is "me.asp":
***** code *****
I am trying to use a regEx to grab Function names and function parameter names from a text entry.
The script is written in javascript and I expect the functions to be in javascript syntax.
For example the code might look like:
Code:
function myFunction1(param1,param2,param3){
some code
}
function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?
Should I be breaking it down into multiple regular expressions?
I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.

Can someone explain how I can use javascript (I am assuming this is the best
way to do it) to add two field values together. I.e. field 1 plus field 2
equals field 3 (this is in a php form)
Also how can I set a field to be a value depending on what the user selects,
i.e. they may have eight items to select from and each one has a different
value.
The above javascript will then use that value to add to another field value
to give a me a total value....
I've got a short form--1 field and a submit button. I want someone to
enter their name in that field, hit submit, and have their name be in

How do I insert this code...
View 3 Replies View RelatedIv'e got a page that has a mass amount of input fields, all of which require
a decimal figure. To make it easier when it comes to inputting data, I'm
trying to setup + and - links that will increment/decrement the form field
value by 1 when clicked.
I'm using the following code, however when I click on one of the links, I
get the following error -
document.forms.tmp.input_field is null or not an object.
It's as if JavaScript is not reading the parameter being passed through the
function.
Here's the code -
<html>
<head>
<script language="JavaScript">
function increment(input_field) {
document.forms.tmp.input_field.value = document.forms.tmp.input_field.value
+ 1;
document.forms.tmp.input_field.focus();
}
function decrement(input_field) {
document.forms.tmp.input_field.value =
document.forms.tmp.input_field.value - 1;
document.forms.tmp.input_field.focus();
}
</script>
</head>
<body>
<form name="tmp">
<p><input type="text" name="temporary" id="temporary" value="0">
<a href="#" onClick="javascript:increment(temporary);">+</a>

Any help would be appreciated. I just can't seem to see the problem...
I wish to use J.S. to obtain the screen ht and put this value into a hidden
field for posting. so that I can then use it in a php file.
A simplified script of what I am trying to do is below, but it doesnt work.
I have not used javascript much and I'm sure its straight forward.
<script type="text/javascript" language="javascript">
var ht = document.body.clientHeight;
</script>
<form action="my.php" method="post">
input name="screenht" type="hidden" value="ht"
</form>
I'm doing an ajax call to a remote php file... it returns a value fine,
and even enters a value into a text field on my form. The problem is,
right after the function call to the ajax function, I do an alert of
what the field value is, and it doesn't recognize the field value has
been changed. Two caveats:
1 - It will recognize the last call's change
(if I run it a 2nd time, it'll see the 1st call changes)
onBlur="ajaxCall(document.form1);alert(document.form1.ajax Field.value);">
2 - It'll recognize the current call's change if I set a 2 second
timeout
onBlur="ajaxCall(document.form1);setTimeout('checkFields(d ocument.form1)',2000);">
It seems, although I can see the text field getting updated,
programmatically speaking, it isn't reflecting it until everything is
done... including any alerts and such.
It's weird seeing the empty alert popup, when I can see the value in
the text field underneath it.
All I need is a script to check whether a field contains an exact code. For example,
A user goes through a game, collects pieces of the code - In this case random numbers or letters to form a 9 digit code.
The user can then enter this code into the field, hit submit and told whether they've cracked the code or not.
So basically something like, if this field contains "123456789" then go to WellDone.html but if it contains anything else other than this code then go to BadLuck.html ,
any ideas? Code:
I need to add an input hidden field to an existing form (post).
I have tried a couple things like adding the '<INPUT type=hidden
name=idSelectedURL value=http://server/documents>' to the innerHTML of
the form but it fails. ie
var sField = "<INPUT type=hidden name=idSelectedURL
value=http://server/documents>";
frm.innerHTML = frm.innerHTML + sField;
also, trying to add an element to the form such as:
var frm = document.getElementById("idForm");
var oField = frm.createElement ('input');
oField.type ="hidden";
oField.name = "idSelectedURL";
oField.value ="http://server/documents";
none of these work and give me a javascript error.
I don't think the createElement method can be used from the form
object, only from the document object. still could not get it working.
I have a name field -I want to validate that there is a space in the field - that the user has put in both firstname lastname and not just one

Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.
<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>
Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.
I have a Javascript that gets data from an XML document and
displays it through javascript. The problem is that when I do
dcfile.getElementsByTagName("subhead")[0].firstChild.nodeName
all I get is #text. Can you tell me why? Code:
How do I iterate through an XML and get each tag name, without knowing in advance what these tag names are?
