Form Elements And Document Models - Structure The Input Names To Get An Array
May 2, 2011
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?
For some reason my script only works when I have at lease two checkboxes. To simulate the problem just run it once with two html input checkbox elements
-> check one checkbox and press submit -> it works -> Now remove one input checkbox field and check the remaining checkbox & submit -> Bamm doesn't work...
In a form, I have multiple checkboxes which represent products whose values are the product prices and names are the product names. When a user clicks submit the next page processes it for cart/purchase purposes.
I need to pass the names of each checkbox to the next page as an array, and it seemed the best way to accomplish this would be to have a hidden input which automatically generates that array in the page then gets passed to the next (via POST) so the application can manipulate the data.
My server-side language is PHP on Codeigniter.
Here's the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head>
Is it possible to change a document structure definitely using JQuery ? I used .html() but after refreshing the page the changes I've done disappeared and were replaced by the default contents
I am creating table rows dynamically through javascript and also creating the input array in each table row. while counting the array elements in IE its give me the correct counting but in GOOGLE CHROME and FIREFOX its give me the only those count like 2 which I do with hardcode
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.
I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.
So far I have this:
function QuantityMWh(form) { var formchk = document.forms[0] for (i = 0; i < formchk.elements.length; i++) { if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {
[Code]....
It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.
I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this:
Next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes...
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:
I use a very handy function (onsubmit) to validate empty fields in a form:
PHP Code: function validate_form(){ var x = document.getElementById("form1"); for(var i=0; i<x.length; i++){ if((x.elements[i].value == "") && (x.elements[i].title)){ [Code]....
It worked like a charm, until I had to change a dropdown dynamically with ajax. I have two dropdowns, the second being populated with ajax (php, mysql) by the option selected in the first one. The second dropdown has the title attribute filled so the previous function can validate and ask the user to select something. However, it seems like fields loaded dynamically with ajax wont appear inside the x.elements[] array. I've tested it over and over, it keeps ignoring it. It isn't even in the array. Why?
Lets say I have an empty array and I want the user to be able to enter as many new numbers as the user wants into the array. Could you explain how? Simply put it: How can javascript parse a textarea and input it into an array. (Like if the user entered 1 3 5 7 4).
<script> function example(form){ var myNumbers=new Array(); then I'll do something with the array once the #'s are loaded...
I'm trying to add the text of a textarea form to the string that's contained at: myarray[a][b][c] It was easy to pull out the value of the textarea with this: textinput = $('#mytextarea').val(); But then when I try to add the variable into the array, it doesn't work. I'm not able (apparently) to do this. Fingers crossed that I'm doing something dumb?
This doesn't work: myarray[a][b][c] += newstringvariable; Nor this: myarray[a][b][c] = myarray[a][b][c] + textinput; I'm guessing there is a very simple (probably syntax related!) solution to this. I'm open to doing this via jQuery or regular javascript.
I am trying to create a XML Document with attributes that needs to be in camelCase.<query maxValue="10" minValue="1">..</query>I am trying to create this xml dynamically using the following code.
var queryXML = $('<xml>'); queryXML.append('<query></query>'); queryXML.find('query').attr("minValue",minVal);
I am writing a ASP.NET UserControl and I am trying to incorporate JQuery into this. The control is a simple form with a few input fields (text, checkbox, select, radio). The first element in the form is a checkbox. Upon clicking this checkbox I want the all the input elements in the form (except the checkbox control itself) to be enable/disable. I tried writing some of this code but my solution was not getting me anywhere. Below is the ASP.NET form code.
I have a draggable marker on my page that sets the value of a javascript variable when the marker is released.I want to submit this value to store it in a database however I cannot figure out how to pass this javascript variable as a hidden form field.Here is my code. I suspect this is completelyhow to make this "lat" value available to me after the form has been submitted.
Code: var origGrp = ['James','Bill','Jennifer','Bob','Karen'];
replaced with something like this:
PHP Code:
var origGrp = [<? $sql="SELECT c.new_userid, c.fname, c.lname FROM ".$prefix."_club_users cu INNER JOIN ".$prefix."_users u ON cu.new_userid = c.new_userid
The form contains 3 file input tags. The name for each is an array. This is for further processing by PHP script. I want to make sure at least one of the file input tags has selected a file.
The rest of the validation script works, but I get a 'not object' error when I include the section that checks the file input tags. Code:
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
Is there a way, in Javascript, to get a list of files in a folder (on a server) that I can dynamically load into an array that I can work with when a page loads?
