Check If A Form Field Contains The Words Jpg And Png
Aug 4, 2007
I have an image validation script that im working on. This is what i have so far...
function validate_form ( )
valid = true;
if ( document.editavatar.avatar.value == "" )
alert ( "Please Enter an Image Url!" );
valid = false;
How can i add to that so that it checks if the avatar field has the words png, jpg, gif and bmp, and if it doesnt, valid will be false. So in other words, if it does contain png, jpg etc it will return valid.
I want to validate a form. In the form is a text field named 'extra' where the user inputs a number. The number is what I want to validate.
However, the 'extra' field is dynamic and does not always appear in the form.
If it appears, there may be only 1 occurrence of it which means it's then not an array but there may also be multiple occurrences of it.
I have a script that validates (and work as it should) if the 'extra' field occurs multiple times and is thereby an array, but I can't figure out how to validate the 'extra' if there is only 1 and to not throw an error if it's not there at all. Code:
Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html>
I'm having users fill out a form where there are multiple rows of data.
Some of the rows can have duplicate data for some fields.
So say on line 1) i have first name, last name as an input fields and some other fields as well, c, d, e, etc.
When the user gets to line 2) if they want to have the same first name and last name as line 2, can I have them check a box and it will automatically populate these fields with the info they just typed in line 1? I can't figure out how to do this.
i know i should have 2 fields for a first and last name in my form but i dont - or has - a java script valadation rule to only allow a one letter character (letter in between spaces such as a middle initial) in a text field if at least 2 words are also included (2 words of at least 2 or more characters)
so if the user input ' John H ' an error prompt would display until one more word is added/at least 2 words are found
right now im using the below coding to allow at least 2 words in the text field but would like to see if its possible to enhance it so it will only block a one letter word if there are less than 2 other words in the form - right now if any words is added with less than 2 characters it will display an error... if anyone knows of a better form of code that needs a minimum of 2 words added and still allows single characters such as middle initials to in a validation script i get lost on validation process'
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
i have an if structure checking to see of the fields have been filled in. On the text fields though there is no value so how can i check to see if nothing there which would mean aint been filled in. i tried
This code works great, it will populate the second box. But I would like it to check if what was entered is a number if it isn't then an alert box shows stating they need to enter a number between 1 - 100, else it populates the second box.
I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?
I have a form that is basically a table from my database.I have checkboxes on the left and only those checked get updated on submit.I�m trying to make an function that is called with an onChange event that will check the box if any of the fields in that row are altered. The id of the checkbox is checkeds[i] where �i� is the row number.The function is firing, but the box isn�t getting checked.
Running into a stupid issue and I am sure it is just something I am missing. I have a hidden field in my page with the default value of HELLO. I am trying to make a change based on the default value, but I obviously am doing something wrong because it won't display my hidden field value. [code]...
The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
