I've got about 40 check-boxes on my 1 form. These check-boxes all have names (obviously) but they are NOT all unique names. The number of UNIQUE names on my form is probably around 8 or 9 (the actual number is NOT important). Because some check-boxes use the same names as other. It's set up this way, please don't ask me to change it, I can't change it.What's the syntax/method for looping through all the names? I was thinking I should do maybe a "for" loop;
for (var i = 0; i < fieldName.length; i++)
But I don't know how to hold a variable of the unique names to start with.
I'm interested in getting an array of unique class names of all option tags under a specific select element. I'm imagining something like this (which does not do what I want): $ ( '#select_id option.class' ); What's the correct way to do this using jQuery?
These DIVS are full of information populated from a MSQL db. So the DIV names cannot be unique. I have this jQuery code:
[Code]....
This code actually works perfectly except for one major headache. When I click the 'hide/show' link on any of these - the only one that hides or shows is the first set. After research I feel like I'll need to use the .parent() selector or (this) somewhere but I feel like I've tried every combination.
I am trying to loop through my top level nav i.e <ul> <li> and then apply that class name to teh sub level menu of that particular top level. So essentially the clas name on the top <li> wil be applied to its sub level items. Here is my code, which isn't working at the moment:
$(document).ready(function(){ var pageID = $('body').attr('id'); var uniquePageID uniquePageID =$("#site-nav ul li",this).attr('id');
I've borrowed some code from various sources to get a delicious JSON feed onto my website. The problem is it this loop gives me the entire feed that is available, where I would only like to have 5 current entries. I understand how to do this in a for i=0 loop, however there is an extra bit of code that I do not understand within the loop. What do I need to do to end this loop at 5 entries instead of the 15 or so it generates?
Code:
<script>
<!--To be honest I have no idea what this does. I sampled code from 3 different resources to make this work, and the author of this code didn't attempt to explain what is going on here. It doesn't work without it. I'm fairly certain it parses the JSON file so that it is readable. -->
I am working on a project where I need to redo the same thing with new variable names
Code JavaScript: var paper1 = new Raphael('img1', 500, 500); c1 = paper1.rect(0, 0, 50, 20, 5); var paper2 = new Raphael('img2', 500, 500); c2 = paper2.rect(0, 0, 50, 20, 5);
I would like to be able to do this with a for loop. So in the above example I would want paper+i, img+i, and c+i was trying eval("paper"+i) but didn't work.
Code: <script type="text/javascript"> $(document).ready(function() { for ($i=0; $i<4; $i++) { var num = $('.clonedInput').length; var newNum = new Number(num + 1); [Code]...
all works well, less one thing. The id names of valores are incorrect in the last loop.
I have a site that has dynamically generated forms with multiple submit buttons. My forms are like this, created using PHP and inserts different user names on the same page:
[Code]....
The member name goes into the JavaScript to variable: member. The Problem: is when this JS tries to submit the form called "john" for example, it searches for a form called "member" instead and it fails. Is there any way to fix this? I'm sure there is a way to deal with this kind of issue but I don't know it yet.
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.
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):
1) Is there a way for the loop counter to loop while less then [a php variable]?
2) Is there a way to use a counter in the name of the form elements? Example, instead of "switchBox1" use: "switchBoxCounter" instead of "nameaddy1" use: "nameaddyCounter"
I have a php file with an almost-standard html form. The not-so-standard part is that the name-attributes of the form elements are dynamically generated as such:
Now I want to do some javascript validation on the fields, but I'm having a bit of trouble accessing the values of the fields. My current code is as follows:
I found a script on this forum that does almost what I want from this thread: [URL]. Instead of a dropdown, I'd like to have a list of names using check boxes, so that you have the option to send an email to one or all of the people. When you choose your selections and click submit, an outlook email will pop up with your selections in the to: field.
Here's the solution using a drop down, this works (and works well), but doesn't quite do what I need : <form name="Contact_Us" id="contact" method="post" enctype="text/plain" onsubmit = "getEml()"> <fieldset id="selection"> Who would you would like to email: <select name = "sel"> <option value="email1@email.com" >email 1</option> <option value="email2@email.com" >email 2</option> <option value="email3@email.com" >email 3</option> </select> <input type = "submit" value = "Submit the form"> </form>
<script type = "text/javascript"> function getEml() { var emailaddress = document.Contact_Us.sel.value; window.location = "mailto:" + emailaddress; } </script>
Is there a way to use checkboxes but to do the same thing? <INPUT TYPE=CHECKBOX NAME="name1@email.com">name 1<BR> <INPUT TYPE=CHECKBOX NAME="name2@email.com">name 2<BR> <INPUT TYPE=CHECKBOX NAME="name3@email.com">name 3<BR>
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'm still struggling with creating a properly formatted form. This problem it two-fold. The first part isn't strictly a javascript problem, but I've included it here because it relates to the second part, which is:
1. Given the form below, how should I structure the input names to get an array like that at bottom?
2. The scripts are used to provide running totals and subtotals. They're fun - try them! But how should I modify these scripts so that they can continue to work with the amended naming policy?
Basically it loops thru the table and creates a row of fields in the form that use the array identifiers '[]' so that I can loop thru them with PHP when the page is submitted.
The key for each array element is the id of the row from the database. So checkbox[] (with value "1") and cost[1] are on the same line in the form. The next line may not necessarily have cost[2] in it, it may be cost[3] or [4], depending the id from the database.
Is there some way I can loop thru these form elements in javascript?
So I need a function to loop through a forms elements and if a value is matched then check that radio button. I have the function call in some other javascript but her is the jist.
The Function function loopForm(form) { for (var i = 0; i < form.elements.length; i++ ) {
I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.
if i do something simple like :
for (var i=0; i<2000; i++) aValue = i+10;
it runs well. But if i do something like for (var i=0; i<2000; i++) aValue = document.myForm.elements[i].value;
it gives me 100% CPU for a long time before i submit the form.
function selectDefaults(buttonGroup){ for (i=0; i < buttonGroup.length; i++) {
if (buttonGroup[i].checked == true) { for (count=1;count < document.addForm.recordCount.value; count++) { var doc = document.addForm.feature1[i] var featureVal = doc.value; featureVal = featureVal.substring(0,2); if ( featureVal == "SF"){ doc.checked = true} } }}}
I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....
How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i] which gives me a syntax error.
The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.
I am actually learning Javascript atm as part of a course I am studying. I am wanting to do some validation for a form I have created. It doesn't validate for non-numeric characters like I want to do and it does not display the end result either.
On my form i have multiple select which all have an id value total1, total2, total3 etc so i am trying to detect how many there are and then use this to caculate a total.
Is there a javascript reference to basically go to a form and produce a loop which will show me how many select drop down boxes there on a form.
Or would i have t use something like
for (var i=0; i < frm.elements.length; ++i) { form.elements.length form_field = frm.elements[i]
and then have a nested if to detect if it is select value or has an matching value ..
