I want to write a generic function since I'm basically doing the same thing over and over. What I'm trying to do is to pass the name of the form and the specific field name to complete the following line: "var testdata = document.form.input.value;".

I am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below:
item1 qty(user input text) * preset price = total price
item2 qty(user input text) * preset price = total price
item3 qty(user input text) * preset price = total price
[code].....
I have a function that gets the value of a clicked on <span> like this:
function getSelectedValue(id) {
return $("#" + id).find("dt a span.value").html();
}
and sets the value of a second span like this:
$("#state").html("value: " + getSelectedValue("state"));
When I echo that second span, I get the selected value from the first span. But I need to get that value into a hidden html form field, so I can pass it along with the $_POST array. How do I do this?
I have a bunch of forms in my page, and want to pass a reference to the current form to a javascript function - when, say, a user clicks on a particular element. Normally, within any type of input field, I'd just add something like this:
onclick="my_function(this.form)"
Then, in my_function( form ) I could refer to form. No worries.
But here's the interesting bit. I also want to run the same function when the user clicks on any <a> tag within a form, like:
<a href="javascript: my_function(this.form)"> ... </a>
Problem is, with this code, the form reference isn't passed to the javascript function. the "this.form" bit doesn't work...
I find this rather curious. So the question is, how do I pass a reference to the current form from within a non input field?
I have a vague idea of what might be going wrong but I have no idea what I should be doing instead. Here is what I'm trying to do: User inputs X and Y coordinates into form validate that they are numbers do a little bit of maths redirect to a php script with a single variable tacked onto the end of the url Here is the form code:
//part of a larger php script to make the form
echo "<form name='gotoForm' onsubmit='return coordCalc()'>
<fieldset>
<legend>Go to Square</legend>
X <input type='text' id='X' size='1' maxlength='3'/>
Y <input type='text' id='Y' size='1' maxlength='3'/>
<input type='submit'

The following (likely far from imperfect code), reports a value of NaN
in the j4 display. I suppose the problem is I am not really passing
the "checked" value of the radio button via .value ... without having
to get this value via html, is there any way I can passed the checked
value via html .. maybe with syntax like n4.checked.value or
something.. Code:
I have a little problem in one of my functions, I would like to pass in a form field name and set the value to something that is passed in. here is my code:
function pickitem(id,type){
opener.document.getElementById("form").type.value = id;
window.close()
}
so i'm passing in an id and a formfield e.g. txtName The problem is with the type.value - i haven't touched javascript for ages so i'm really rusty!!
I was wondering if anyone had come across some javascript that would
allow me to have a chart of say 20 music tracks, and be able to move
each track up and down the chart using up/down links? I am sure I saw
one about 3 years ago.
Consider this:
A table with a form around it. Each row of the table is numbered 1 to
20. There will be a form field on each row for Artist, Title, Label, Mix
and Genre. There will also be an up and down arrow to move the contents
of each row up and down.
I need to create 2 javascript functions. 1 to swap the contents upwards,
and one to swap downwards.
The link to go up or down will pass the row number to the function, and
the fields that need swapping. The function will then take the values
and swap them over.
Is this possible? And will it work cross-browser cross-platform? Any ideas?
I'm trying to make a function that will enable any given form field. This is what I have, my form name is 'searchfields':
Code:
function EnableDisable(field)
{
var loc = 'document.searchfields.'+field;
loc.disabled = false;
}
When I run the following code the script will not display the second id field from the form:
function enCrypt( code ){
var form = document.getElementById( 'myForm' );
document.write(form.cipher.value);
document.write(form.msgcode.value);
} // end function enCrypt
</script>
<form id = "myForm" action = "">
<p>Enter cipher : <input id = "cipher" type = "text" /></p>
<p>Enter message : <input id = "msgcode" type = "text" /></p>
<p>Result : <input id = "result" type = "text" /></p>
<input type = "button" value = "Encrypt"
onclick = "enCrypt()" />
New to working with javascript and I've come up with a function. I have a form with a dropdown and input field:
<form>
<select name="warranty" id="warranty" onChange="doadate()">
<option value="Select">Select</option>
<option value="In Warranty">In Warranty</option>
<option value="Out of Warranty">Out of Warranty</option>
<option value="DOA" selected>DOA</option>
</select>
<input name="doadate" type="text" id="doadate" value="<? echo $doadate; ?>"
size="20" readonly>
</form>
I need the input field to be disabled unless DOA is selected in the select form element. I've started on page load with document.form1.doadate.disabled=true. Then I've put an onChange handler in the select to call the function below:
<script type="text/javascript">
function doadate(){
val = document.form1.warranty.value;
if(val=='DOA'){
document.form1.doadate.disabled=false;
} else{
document.form1.doadate.disabled=true;
}}
</script>
But it's not working, it stays disabled after load even when the DOA is selected in the drop down form field.
Tried searching but didn't seem to find a solid solution to my problem I'm trying to pass a value to an input form field, from a function. Here is my code
PHP Code:
<script>
function createDiv(sceneNum, startTime, endTime, dialog, notes)
[code]....
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.

I am trying to pass the value of a field to a PHP file like this:
<input type="hidden" name="field1" id="field1" value="123">
<input type="hidden" name="field2" id="field2" value="456">
<a href =
"test.php?c1=document.getElementById('field1').valu e&c2=document.getElementById('field2').value[color=blue]

In test.php, when I do:
c1=$_GET['c1'] ;
echo c1;
I get:
c1 = document.getElementById('field1').
I am facing a problem in passing replace() function as an argument in user defined java function.
intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '' to '\'
I am posting my javascript function here:
<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\/g,"\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>
function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}
I have a lot of similar instances of the following code on my page:
$('#btnEditParty').click(function () {

I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.
I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.
This post is where I was doing something similar to save repeated code: [URL]
In a similar way is there a way of passing in a function name to be called on success?
The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
function validate_form ( )
{
valid = true;

I have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?
View 4 Replies View RelatedI would like to have a main form (written in PHP) that has a "lookup" button next to a text field. When the user clicks "lookup", it should open a new window that lets them search (child.page1). When they enter a name or DOB into the search form, it submits the form through PHP (via POST), to a results page (child.page2). This displays all persons in the database which have a name or DOB == to the search term(s), with a checkbox next to each match. They click the checkbox (or alternenatively, a link), and return the checkbox value to the main window.
I have everything working right now, except that (child.page2) doesn't recognize the main window. If the data is entered on (child.page1), it works fine. I'm not very familiar with javascript.. is this even possible? I've considered using frames, to keep the parent-child relationship evident to the computer, but figured I'd check to see if there's an easier way.
my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:
//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()
function validate_join()

I have issue with passin value between functions:
$(document).ready(function(){
id = 'test';
$('#Meno').keyup(function(){
id = '#Mobil';
[Code].....
I am getting from console.log right value "#Mobil" but $(id) has value "Test". I need there also value "#Mobil".
In one variable i have some data ex: var data = document.getElementById("imageId").value; I want to pass this data to another function inside another function ex: var button1 = '<img src="images/Remove-button.gif" width="70" height="15" onclick="removeVerifyImageRow(this),saveLibData('+data+')"/>';
while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'.
Here is the code:
for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
[Code]....
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to:
var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };
In one variable i have some data ex: var data = document.getElementById("imageId").value; I want to pass this data to another function inside another function ex:
var button1 = '<img src="images/Remove-button.gif" width="70" height="15" onclick="removeVerifyImageRow(this),saveLibData('+data+')"/>';
while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'.
Is there a way I can calculate a field in a form based on another field in
the same form. When clicking submit, both values should be posted to the
next page. I want to be able to type in a value in one field, and
automatically in a second field the value*1,36 should appear.
