My javascript at the moment allows me to enter digits into textboxes, with the result of them all being put totalled up in a seperate box.
However, the numbers inputted are referring to money. This means that some users may put commas or full stops in. Does anyone know how I can parse such punctuation, so javascript just reads it as a full number without the commas etc. As it stands I just get a NaN error.
I have a large form, that has text boxes of numbers in rows and
columns. I need to sum the values in the columns, and put the total at
the bottom of the column. But I also need to sum the values in each
row, and put the total at the end of the row.
What is the javascript to sum the values to a few text boxes, and how
would I write the script for these totals to run all at once?
I'm a complete beginner to JS and have been playing around with a few test projects but I am stuck with one particular part.It simply creates a new text box if you press the Add Text Box button, and removes the text box if you press the Remove Text Box button.What I want to do now is add a usable value to each text box (e.g. the first text box will have the value "tb1", the second "tb2" and so on - so that I can post the data to use it further on.
View 3 Replies View RelatedI having been trying to make the data from generated (using div tags) pairs of textboxes into two separate arrays, a[] and b[]. I thought that if I label each text box pair a[i] and b[i] that would be enough to include the respective element in each array but that hasn't seemed to work. In fact. the only way I managed to retrieve the values from the text boxes was using "getElementById" and resorted to a for loop in order to make the arrays but that method appears to be able to get elements from only one pair of text boxes. Code:
View 3 Replies View RelatedI am trying to take the values of 2 or more select boxes, add them together and then update a text field each time a selection in one of the select boxes is made. Basically, I am trying to keep a running total.
Currently I have it set up so that onchange it grabs the selected value. The problem is that it is being processed as a string I believe. For instance, if there are two variables, a=111 and b=222, the output in the text field reads 111222. I tried using parseInt, but that just returns NaN (not a number?...just a guess).
I have seen this solved with if statements, grabbing the selected index # and then assigning an integer, but I am hoping there is an easier way.
im wanting to add check boxes up to create a total sum at bottom of the form or anywhere for that matter.im wanting to add the values up of the check boxes and then the total amount of checked boxes appears in the total amount. also ive been trying to get it when you uncheck a box the amount goes away from the total amount.here is what ive got

I have the following page [URL] and I would like to add a button or checkbox to check/uncheck all. Note we are already using some javascript for custom checkboxes so it needs to integrate with that.
Here is the current javascript...
/* Custom Form Element [URL]
The only thing you need to change in this file is the following variables: checkboxHeight, radioHeight and selectWidth. Replace the first two numbers with the height of the checkbox and
radio button. The actual height of both the checkbox and radio images should be 4 times the height of these two variables. The selectWidth value should be the width of your select list image. You may need to adjust your images a bit if there is a slight vertical movement during the different stages of the button activation.
Visit [URL] for more information.
*/ var checkboxHeight = "47";
var radioHeight = "25";
var selectWidth = "190";
/* No need to change anything after this */
document.write('<style type="text/css">input.styled { display: none;
} select.styled { position: relative; width: ' + selectWidth + 'px;
opacity: 0; filter: alpha(opacity=0); z-index: 5; }</style>'); .....
I'm currently working with a bit of javascript to dynamically add
<option>s into a select box. My code currently works fine in Internet
Explorer, however in Firefox the dropdown only displays the first
option in the list, and when clicked the other values aren't displayed.
Here is the code;
//ar_options is an array with the option to be displayed in.
for (count=0; count<number_of_options+1; count++)
{
document.forms['enquiry'].enquirytype.options[count] = new
Option(ar_options[count],ar_options[count]);
};
As I said - fine in Internet Explorer, but not in Firefox. I did
discover some discussions about this, which were talking about an issue
and workarounds but I couldn't get any of them to work. I have also
tried simply using the document.write() function to output the HTML in
the correct place. However this is just hte same, works in IE but not
Firefox.
ave 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 adding drop down boxes to a div using javascript on a user action, if these boxes are assigned a value by the user then the user adds more boxes the values previously selected are cleared.
It does not happen if an option is selected in the HTML when the page is loaded.
how to add up a series of text boxes which contain numbers that a user will input and have the total of those text boxes show up in a quantity text box on the next page.
Not sure if i should use javascript or php, but i don't know how to do it either
i have a multiple page form where on one page i ask my user to enter a number into a textbox. i would like to know how to get some textboxes to appear on the next page in relation to the number they enter on the first page. i.e. if they enter 10 in the first text box, 10 textboxes appear on the next page for them to enter data into and then press next to go onto the following page.
View 2 Replies View RelatedI have a table of textboxes which is dynamically create (based off the number of users and levels in my db). I want the sum of each row to be 100 - the easiest way to ensure this is to update the row sum after any change in the textboxes.The kicker is that I need to keep the user/level associations so that I can upload the new numbers to the database. Was thinking of using name="L5-U1" (level 5 - user 1) as the name attributes for each of the textboxes but unsure of how to sum the boxes using this method.After some further research, I think the best way is to assign the same class per row and add up all the textboxes in that class. What code would I use to auto-select the affiliated class? (e.g. I can't have a specific class listed in the function since they are dynamically generated, need to use "this" or pass the class name via onkeyup)

I'm building a function that I'll use throughout a website in the situation
that I have two text boxes - the two text boxes will generally contain the
same data. After the user completes the value of the first textbox, I want
to onChange the value of the first textbox into the second textbox UNLESS
the second textbox already has a value.
Here's what I've done so far...
IN THE HEAD
function CopyTextBoxes(TextBox1,TextBox2) {
if(TextBox2.value = '') {
TextBox2.value = TextBox1.value}
}
IN THE BODY WITHIN THE FORM
<input name="MailFrom" type="text" id="MailFrom" size="60" maxlength="100"
onChange="CopyTextBoxes('MailReplyTo','MailFrom')">
<input name="MailReplyTo" type="text" id="MailFrom" size="60"
maxlength="100">
I'm trying to create a javascript function that will allow the user to
press a button within the html code that will add a text box right
above the button. If the user presses it a second time it should add a
second text box right under the previous text box. Any ideas?
in my webpage, i've a form which contains several textboxes and a submit button. all the textboxes are generated using php looping method.so, what i wanna do is, when user click the submit button, it will sum up all the textboxes values and pop up alert message telling the total value.

View 4 Replies View RelatedI am doing a web development project.I have a product page which has 2 buttons. By pressing one button, a text box gets displayed and the user types in the value and after saving it the text box should disappear. When the user clicks the button again, the text box gets displayed and the user can type a new value(like text1, text2...).
There is second button, when it is clicked it displays the text box with the value that the user typed in the text boxes(text1,text2...). when we click the second button, it should display text1, text2... in a graphical view and the user can edit or delete the text boxes and rearrange the text boxes and save the online work in his webpage for future use.
I have created the text boxes dynamically(as many boxes as the user wants) and he can drag and drop the text boxes in the page. I need to create a dynamic line from one text boxes to other text boxes and delete the test boxes which the user does not want. I have created the dynamic graphic line. I know the values of the text boxes can be saved using php in the backend. But is there any way the values with the dynamically created boxes(with <div></div> elements, not with the text boxes) with values and graphics line can be saved online and the user when log-in again can retrieve the work that he saved? Can we code this either in javascript/php?
View 4 Replies View RelatedI've seen on various websites where you can roll over an image or hyper link and a text box pops up. Some are very simple looking while others have graphics. I'm assuming it's done through Javascript but I'm not sure.
View 1 Replies View RelatedI have a php page that dynamically generates any number of text boxes.
To validate its input, I need to know how many text boxes are in the form.

I'm sure that's completely wrong but there has to be a way to count the number of elements in a form.
As part of my form I have a box for the user to input the number of text boxes needed. I already have the page creating the textboxes but do not know the IDs of each text box. Once the user adds textboxes they can click add again to create more. If the user previously added 3 textboxes and now enters 4 I want the program to just add one more instead of 4 more.

Have an example with an orderform for two products. The form has columns of textboxes. Split in a lot of sections (showing the first two as an example) These textboxes are then sent to a PHP script. But I want to validate that the form is correct first. In the last section I have two textboxes "sum_amount1" and "sum_amount2". Basically I want to add up all amount1[] boxes into sum_amount1. Not using textbox1 + textbox2 etc. but instead using a for loop.
