i have a form and would like to check two fields.
if field 1 containes the letter 'c' and the other field contains
'undefined', then an error should apprear ina box on the screen.
can anyone point me a piece of code ?
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!
I have a form that I am trying to loop through the elements of and come up with a total, when the form is submitted. The goal is to alert users that they have not entered a minimum or maximum number of choices before letting the form submit. The fields in question might be checkboxes in some cases (with a value of 1) or textboxes in others with user-submitted values. Here is a stripped down example...The html
<form class="phpws-form" id="elections_vote" action="index.php" method="post">
...
<input type="text" name="Candidate_Vote[2]" id="Candidate_Vote[2]" size="3" value="" />
<input type="text" name="Candidate_Vote[3]" id="Candidate_Vote[3]" size="3" value="" />[code]....
...problem is, is that total is always 0. I know I'm missing something, and I suspect that 'inputs' is not what I want it to be,
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 am having some trouble trying to fix my math equation to calculate the total rent by aquiring values from my form fields. Converting the date fields to days and finding the number of days via two date fields is mainly where I am having trouble. Also, I am trying to have a window pop up before submission but the onclick event does not seem to function properly.Below is the math equation I have come up with:
//calculate days from date field
function calcTotal(date1, date2) {
//assign variables

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.
I am trying to assign values to a bunch of form fields. However, I don't want to loop through EVERY field in the form, just a specific subset of fields. The fields I am trying to change are all named similarly myField1, myField2, myField3.So, my thought is that I would like to use a for loop and loop through the appropriate fields by simply incrementing a variable and appending it to the end of the string "myField" in order to change the appropriate field.How can I evaluate "myField + iterator" into a useable reference to change the value of said field?
View 6 Replies View RelatedI'm working on an ordering form which calculates the total order price using Javascript. I have a checkbox which I want to use to toggle the display of various items, and also reset the value of an item depending on whether or not it is checked.
Further details
I have a checkbox for the colour "Black" which, when checked, hides a SELECT, a bit of text, and "Quantity" field. It also resets the value of the "Quantity" field to zero.
When the "Black" checkbox is unchecked, the three items (SELECT, text and Quantity) are revealed again, and the Quantity field for "Black" is reset to zero and hidden.
The reason is that users can only either EITHER a black item or select from a list of colours. Black items are a different price to all others.
How the form works
When the user enters a quantity into a text field for each item, the price of that item is added to the total at the bottom of the form. When the form is submitted (with PHP validation), it emails the order to a salesperson. The price of each item (for emailing the order) is set using hidden form fields with defined values, while the order total is calculated using the id of each quantity field (e.g. "item_31_85.00").
What I need to know
I want to achieve the following when the "Black" checkbox is clicked:
Toggle the display of three items (SELECT field, text (in a DIV) and an INPUT)
Reset the value of the INPUT field (and reset a different INPUT when the checkbox is clicked again)
My current code
The code I'm currently using in the PHP form is below (truncated for readability):
Code:
<input type="checkbox" name="black" onclick="togglecontent('colour_box','colour_price','color_quantity','quantity_reset')" /> Black
[Code].....
Currently I can hide the SELECT and accompanying text when I check the "Black" checkbox, but it won't reset the INPUT value nor hide it. I've not yet attempted to do unhide and hide the Black text and input since I can't get this part working yet.
I designed a form having ten fields, will it be possible to have a jquery function that will make all the values in the form field to be displayed in a separate div outside the form by click of a button or a link?
View 3 Replies View RelatedI have a contact info form with about 16 fields. I need to hide a subset of fields for address when the end user either (1) tabs out of the subset group, (2) clicks anywhere outside the subset field group.
I do not want to hide the fields when the end-user is tabbing within the subset of address fields, yet the focusout handler is triggered when it shouldn't be.

I have a input field (text field) in my html page. User should give input as a string like following 12 345 678,0 If user gives input in format 12345678,0 and leves the input field how can I format the value 12345678,0 into format 12 345 678,0?
Are there any Javascript that can handle this with Regular Expressions?
There are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?

I have been looking for the past 2 days for a script that I can add and delete table rows.
I have found a lot but so far all of them add an input field but I desperatly need a textarea or ideally a section of input fields.

Have you come across to a similar script.
I would appreciate any contributions.
What I am trying to do is a page where the user will add their employees details so we can order business cards for them. So I have fileds such as, Name, Tel Num, Email, Cell etc.
I have this order form where the customers can change the quantity by intput in a text field.I would like to have the text field changed with select fields, but doing so in the form, the script is not doing anymore.Can anyone have a look and tell me what to change in the scritp to accept select fields in place of the text fields.

If a user enters a value into the textbox, I want him to be able to move on only if it's a number, otherwise have text come up next to the textbox saying that he should enter a number.
I have another problem (Im not very handy with javascript).I want to check if a value entered into a form is a whole number. This means it cannot contain a decimal.I wanted to use isNumeric() but realised that allows for decimals.Is there a way I can make sure a value is simply a whole number (0-9)

View 1 Replies View RelatedIs there way to make it to where if someone clicks one check box the rest get checked without knowing the names of the other form names? Meaning if I load a form with a dynamic number of entries, maybe it will show 8 check boxes or perhaps 6 and I wont know the name of the form fields. So is there a way if they click one main check box the rest get checked?
