View 9 RepliesI have a form with some checkboxes and I would like to submit it(through jquery) only if at least 1 checkbox is checked, otherwise Iwant to display an alert message.How can I get the number of checked boxes?I tried $("INPUT[type='checkbox']").is(':checked')but lookslike it doesn't work.Any ideas about how I can achieve so?
View 3 Replies View RelatedI have a javascript function for DOM scripting Its a search with certain Nodes which by Default is checked upon clicking the submit button it shows results in a diff table
The problem is that it works perfectly fine in Mozilla ,Firefox but Not Internet Explorer. The check boxes next to the Nodenames are not checked and the search does not display the results in a table. however it works perfectly fine in
Mozilla browser. In IE it shows an error with 'a object required' for checked boxes . As i think, It s coming from the save search option function, i am not sure if i have to create another object for calling the .checked operation in the search table Code:
Much like gMail, I have a list of files with checkboxes and a number of submit buttons with options.What I'm trying to do is enable or disable these submit buttons depending on how many checkboxes are checked.ie. if only one checkbox in the group is checked, enable the "Get Link" button but if none or more than one is checked, disable the "Get Link" button.Similarly, if none or only one checkbox is checked, disable the "Get List" button but if more than one is checked, enable the "Get List" button.I'm afraid I have no idea where to start!There are a couple more options but I'm sure I could figure it out after that.

I created the edit page where all the info is loaded from database. It has check box checked on load from the database values.How can I open respective text boxes if check box checked on load .
View 1 Replies View RelatedI want to compare the total number of checkboxes with the number of checked checkboxes of a certain nameI use these 2 functions:
alert($('input[name=checkItem]').length); // To get the total count
alert($('input[name=checkItem]:selected').length); //To get the total selected count
The first one works, the second one doesn't.
I have a dynamic html. i'm trying to count the number of checkboxes checked.
For some reason this isn't working.
Code:
Is there a way with JS that i can have some sort of label at the bottom of each column that will in real time display the number of boxes in that column that are checked? I am guessing it will be a function that is called within the OnClick method of the checkboxes.

To validate its input, I need to know how many text boxes are in the form.
I'm currently trying something like:
Code:
I'm sure that's completely wrong but there has to be a way to count the number of elements in a form.
I'm just trying to find the best method of updating a running total of the value of list boxes. I basically have 6 items and I want a drop down box listing quantities. when a number is selected I want a total to update beneath. I'm not sure I can do this in PHP without reloading the page. Do i need to use Java script? if so I'm a total newbie can someone point me in the right direction?
View 2 Replies View RelatedI have to input an undefined number of rows of data. Existing data is read from a database. There is an Add button after the last row.
I can see how to add the next row: there is a hidden blank row with visibility set to 'none', which is turned to 'block' by clicking the Add button.
How can I continue to add rows? Do I need to have a large number of invisible rows and turn each one on as required? (I don't want to have to submit the form for each row, which would be another solution).
I have multiple checkboxes. How can I validate the group of check boxes so that a user can only select two. If they try to select more than two, an alert will pop up stating they can only choose two?
Code:
I need a drop down box with numbers 1,2,3,4....listed. When the user selects 2, two text boxes appear below, ajax style ! if they select 3, three boxes etc etc.
View 5 Replies View Relatedave this form which gets created by pulling stock/products from a database using PHP and beside every product in the row is a little box for input and in there the user can input the quantity of the product they want. Sometimes only 2 products will be outputted and other times 10 or more.What I want to happen is when the user enters in lets say 3 for the quantity of a certain product I want to get a total for how much 3 of that product will cost so I just do 3 multiply by the cost (which I have from the database) and then display the total cost down under where the list of the available products are and I want all this to happen dynamically obviously not using PHP because I don't want the page to have to reload every time they enter in a new quantity.
I know how to display text and stuff in certain divs with certain ID's using Javascript but I just don't know how to keep track of a form and do what I want to do when the number of inputs in the form can range from 1 to 10 or more. Im thinking of some sort of counter which gives every input a different ID like add 1 at the end of the ID name of the input as the PHP script loops through the database query displaying the products but I still don't know how to go about the Javascript side of things
I am working on my assignment: The assignment is: The process of finding the largest value (i.e., the maximum of a group of values) is used frequently computer applications. Write a Javascript program that input a series of 10 single digit numbers as characters, determines the largest of the number and output XHTML text that displays the largest number. Your program should use 3 variables as follows:
a.) COUNTER: A counter to count to 10 (i.e. to keep track of how many number have been input and to determine when all 10 number have been processed). b.) NUMBER: The current digit input to the program.
c.) LARGEST: The largest number found so far.
Below is my code so far:

When I find a record such as this in a textarea:
[Code]....
There will be from 1 to 4 Pts, if one is missing there will not be a next one. My problem is I replace the first occurrence of any number I find and for certain factors (2 in this case) it could change an already converted number and leave other fields in the record alone. I could split the line on commas to change the first number I find but can't be certain if there are no other commas elsewhere on the line.
FRom this page: [URL]I need to find the VIN number and store it in a variable, however there's no ID located in it, so getelementbyid doesn't work.

If i have 4 vars
var one = 29.1
var two = 5.4
var three = 12.4
var four = 15
how can compare all 4 and find the smallest? in this case the result would be two
Is there an efficient way (ie. not looping through all members and counting) to find out what number an li will get in an ordered list? For example: [code]...
Naturally #first and #second will be 1 and 2, respectively. Without looping though all children of ol and counting, can I determine the number for #first and #second?
I'm just a starter and I'm looking for a function I can't find.
What I want:
I want the row number of the row i clicked of the item list.
For instance I click on third row then I want that var i returns 2. code...
Basically I want to factor a number and select the two closest numbers to the middle of the factors for example: 20 factors to 1, 2, 4, 5, 10, 20 I want it to return 4 and 5 If the number is has an odd number of factors (has to be a perfect square) I want it to select the middle number and say it twice for example:
64 factors to 1, 2, 4, 8, 16, 32, 64
I want it to return 8 and 8 Would I use an array or what? My code should probably look like:

After retrieving a record from the database and displaying one of its text field in an input-type textbox, I click on a word and it'll store or show the current position of cursor in a variable. I have no success with IE's caretPos.
View 4 Replies View RelatedI am trying to use some dead software made by Grandasoft (XSDesigner & XSForms) that sllows for the creation of data-collecting forms on handheld devices. The software works fine, and is exactly what I need, but...In the Form Design half of the software, you can create more complex actions (OnChange, OnCreate, OnSetfocus, and OnKillfocus)- these actions need be written in either Jscript or VBA.I have created a series of radio button entries which allow either "yes, no, maybe, or significant" to be selected as possible answers. Whichever button is selected, the data is stored as text ("maybe" for example).Now, at the bottom of the form page, I have a series of [text] totals boxes, for which I desperately need Jscript code: "Total number of radio buttons checked "maybe;" "Total number of radio buttons checked "significant;" "Total number of radio buttons checked "yes;" etc.
I have been floundering for the past 2 weeks trying to learn enough code to make sense of my problem. Could one of you provide me with a code that would automatically sum the number of "maybe" values?I think I could rearrange the other values to create similar for my other totals boxes.My 'maybe' Total box is apparently called:tbxPermRd_MaybeTotal.Value The radio buttons are called:optRespectSensitiveAreas.Value optRoadsmeetgradespecs.ValueoptDitchesdontdumpintostreams.Value
I am having some difficulty in constructing a window.confirm() function that works with my code.So if the form data is valid, I need to use a window.confirm() dialog box to show the user's total cost based on the rental rate of equipment chosen and the reservation period. The user must accept the cost by pressing the confirm button, and if user cancels do not submit data.I have written this code but cannot figure out how to find the number of days from the 2 date fields and use that to calculate and display the total cost.
//confirm submit and display rental cost
var equip = document.forms[0].equipment.value
var pDate = document.forms[0].pickupDate.value[code].....
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
