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 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.
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 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.
Code:
Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.
(Example)
If the 4 text boxes have the following values:
In the database field they become:
However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.
(Example)
All 4 text boxes display this:
I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!
Also, this is kind of irrelevant but just in case you're wondering, this form is part of a cold fusion application!
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 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?

I've a page where I'm calling record from Database. Each record has an
ID and a text box displayed on the page. When the user fills in the
values of a text box, depending on the values of the text box i've to
do some further work. For eg. I've to add two records if the textbox
value of 2 records is same.
I'll try to create an example here
<-----this is from the DB-------> <-----this is form field--->
ID Task Hrs text box
1 adsfsd 1 a <---- user fills this
2 asdf 1.5 b <---- user fills this
3 eyst 2 a <---- user fills this
4 dghjfghj 2 c <---- user fills this
5 xdfb 1 b <---- user fills this
6 tyety 1.5 c <---- user fills this
________
| Submit |
--------------
So the user has to add hrs of those boxes for which have same values
entered by user. such as adding hrs of record 1 and 3 since both have
"a" entered by the user, adding record 2 and 5, as both have "b"
entered by the user and so on and so forth.
i am inserting values using AJAX.for single record its working fine. but i want to use five text boxes for the same function and for each text box i am calling same function.but now value are not passing properly..whetever passing first time only that value is going into database twice or how many times i have entered the values .so i want my function should work dynamically.with each add button should take value for that text box only.
here is my code
Code JavaScript:
// Optional: Show a waiting message in the layer with ID login_response
document.getElementById('insert_response').innerHTML = "Adding..."
// Required: verify that all fileds is not empty. Use encodeURI() to solve some issues about character encoding.

how to sum the values stored in an array of textbox using javascript and display it in a separate text box.
View 7 Replies View RelatedI have a dropdown (picklist) on the page, and when the user selects one of the company names in the list the onChange event fires and kicks in some AJAX to get the company's details from the database. The details are just the various locations of each company.
The way I am doing it now I have a simple div on the page below the picklist and I am using PHP to draw out the entire HTML, including the values sought from the database, and then just using innerHTML on the div to dump the info in there.
So I have PHP which concats text like:
"<input type="text" name="city" value="$city">"
"<input type="text" name="state" value="$state">"
and then the JS innerHTML's it into the div.
But it strikes me this is not really an efficient way to do this. Should I just have the PHP form an XML doc and then use that to populate the form fields?
If so how do I use the DOM to create text fields on the page, and then populate them with the info returned from the DB?
I neeed to subtract values from two text boxes and then show the difference into a html label.
Basically I need to enter times, like 10:00 and 12:00 and it calculate that the difference was 2 hours.
I want to do is add the values of seven text fields on a form and pop that value to an eighth field. I thought the code below would work, but I get "NaN" on the sum field.
Code:
function addHazWaste() {
document.getElementById('HazardousWaste').value = 0;
var HazWasteTotal = 0;
var HazWaste1 = 0;
var HazWaste2 = 0;
var HazWaste3 = 0;
var HazWaste4 = 0;
var HazWaste5 = 0;
var HazWaste6 = 0;
var HazWaste7 = 0;
HazWaste1 = parseInt(document.getElementById('HazardousWasteSentToLandfill').value,10);
HazWaste2 = parseInt(document.getElementById('HazardousWasteSentToWasteToEnergy').value,10);
HazWaste3 = parseInt(document.getElementById('HazardousWasteIncinerated').value,10);
HazWaste4 = parseInt(document.getElementById('HazardousWasteRecycled').value,10);
HazWaste5 = parseInt(document.getElementById('HazardousWasteReused').value,10);
HazWaste6 = parseInt(document.getElementById('BiohazardousWasteSentToLandfill').value,10);
HazWaste7 = parseInt(document.getElementById('BiohazardousWasteIncinerated').value,10);
HazWasteTotal = HazWaste1 + HazWaste2 + HazWaste3 + HazWaste4 + HazWaste5 + HazWaste6 + HazWaste7;
document.getElementById('HazardousWaste').value = HazWasteTotal;
}
If I run a separate function that just sets all form field values to zero (including the first line of this function). The summing works!!! Why won't it work the way I wrote it??? It won't work if I set the default value for the sum field to zero, either...
I 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.

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.

i'm trying to develop a code for my sister, i would like to use javascript
to finish off the following task:
1. I want to be able to select marks from 0 to 30, from 5 drop down boxes.
2. and as marks are selected, it should upgrade the total.
3. and then show me the total marks when finished.
i've got up to creating the drop down boxes, now it's just adding the values once selected.
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.
I am trying to add values of selected options in select boxes that update on any change...
I don't know why this is not working [code]...
I have two basic select lists and I want to automatically submit the values from the first list once they select from the second list using onchange. how to get the multiple values from the first select.
So basically I want them to select a state or states from the first list and in the second list they can choose from some data parameters to query within those zip codes. So once they select data parameter(s)... the onchange should kick in and pass both the zip code selections and data parameters to the getData function.
Trying something like:
PHP Code:
<select name="state" multiple size="5" >
<? while($row=mysql_fetch_array($result)) { ?>
<option value="<?=urlencode($row[0])?>"><?=$row[0]?></option>
<? } ?>
[Code].....
By using state.value I get ONE of the select items and not multiple. And I've tried state[] and variations of state[].value or state.value[]... no luck.
The onchange=getData is a function that puts together a URL to get data from another page. So I really need to pass something like state[]=1&state[]=2
Therefore it seems like the state select needs it's own onchange to run a local function that formats this URL string??? then how do I get that value?
I have it working as two completely seperate form elements but I really want to make these two selects one form/step that they have to complete.
