I am looking for a little help validating a forms input. On the form are key
items which I do not wish to be zero length.
I have wrote the following function:
<script language=javascript>
function ValidateLength(oid, min, max)
{
var txt = document.getElementById(oid);
var length = txt.value.length;
if(length == 0)
{
alert("You must enter your reference, Company Name and Contact Name");
}
}
</script>
However their are still a few issues I would like to work out.
I all it with my forms sumbit event with the following:
However that will only check the length of the item txtRef, how can I check
more textbox values? Also how can I stop the form posting if the alert is raised?
I have the code for the form, it asks for the quantity of certain items to purchase and displays them. The next exercise I needed the Quantity to test for Numbers only. I need it to give an alert if there is a NaN entry and stop the program otherwise it continues on with the calculations.
PHP Code:
<script type="text/javascript"> var SalesItems = new Array (); SalesItems ["Webcam"] = "50.00";
This code will not work no matter what I do. function comparePassword(){ pass1 = document.getElementByName('password'); pass2 = document.getElementByName('cpassword'); if(pass1.value != pass2.value){ document.getElementById('matchpass').innerHTML = "Passwords do not match!"; }} <!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 TransitionalEN" "[URL]"> <html><head> <title>Game Makers United - Uniting game makers with the help they need</title> <script language="Javascript" src="javascript.js" type="text/javascript"></script> </head><body>
All it's supposed to do is check whether or not "password" and "cpassword" match, if they don't it's supposed to put "Passwords do not match!" in the span "matchpass". I can't see anything wrong with the code and javascript is enabled in my brower. GetElementByName does not exist, so I switched it to getElementById and it works perfectly.
It doesn't appear to be possible to validate multiple forms on a pages that only has a single <form> tag, using the JQuery Validation Plugin offered by Jörn Zaefferer. The reason I need to do this is because my pages are created with ASP.NET whose architecture generally calls for a single page-wide <form> tag. In my designs, I'd like to submit my data using a custom ajax call to a web-method, and link it to a click event on a button.
Below is an example: <! DOCTYPE html PUBLIC "-//W3C//DTDXHTML1.0Transitional//EN" "[URL]" > < html xmlns = "[URL]" > .....
I'm not sure that I fully understand the documentation for the Validation plugin, but it doesn't seem like this is possible, as the plugin seems to need a <form> for each form.
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.
I am validating a page (image attached) to make sure that total hours entered do not exceed the allocated amount, which is stored in the database. I have already validated to make sure that they enter a number and that it is not greater than 8.
var returncode = true var inputs = document.getElementsByTagName("INPUT") for(var x=0; x<inputs.length; x++) {
I want to check that only letters were entered in a field.formElements[i].value.search(/^[^a-zA-Z]+$/) != -1Will the above line be true if characters other than letters are found?
I'm working on a site where the name attribute of an input will not be known beforehand. I'd like to be able to modify or extend the validate plugin to set the rules and messages based off of the id of an input instead of using the name.
I have a selection list that users can choose one value from about 300 different values. I wish to add some cross value vaidations to ensure some extra data gets entered should the user choose one of 50 of these values. Now I know I can write a JS validation individully fo each of the 50 as follows:
if theForm.field1.value=="25" && theorm.field2.value =="" { alert("Enter field2 value"); }
Then repeat this alidation 50 times.
My question - is there a way to shorten the code to someting like this:
var fieldx = "1, 2, 3, 4, 5"; etc with all 50 values defined here, then something like:
if theForm.field1.value==fieldx && theForm.field2.value =="" { alert("Enter field2 value"); }
I'm working on a page that has an iframe that loads a page with a file input on it. What I need to do is validate that file input to make sure that it isn't empty.
I am having 2 input fields. Both will have only the integer values. Its a minimum and maximum values. The condition is The minimum value of the 2nd input field should be greater than 1st input field. and 1st input field value should be minimum than 2nd input field. For that I tried with
I'm trying to fill out a form on this site using JavaScript: [URL]
However, the fields do not have input IDs; they only have span IDs. I've tried using the span IDs, but it doesnsn't work. Here is the code I'm trying to use:
document.getElementById('fn'). value='" FName "';
Where FName is the value I want filled into the field. Could someone please tell me how to use JavaScript to fill in the fields of this form (and check those pesky check boxes)?
I'm trying to write some javascript code that will give a user one of two messages (Correct or incorrect) base on whether they answer a question correctly. I have 2 issues that I was hoping someone could help me with:
1) My "incorrect" and "correct" messages all appear on the page load. Is there anyway to start without them being there?
2) More troubling: No matter what I put into the input boxes, the "incorrect" message pops up. Basically I need to better understand how to grab the actual input value (it's commented down below so I think that this should be a quick fix!)
Code: function showAnswer(blurred,response) { var form = blurred.form; var rbs = form[blurred.name];
The tricky part is that I want the availability of certain fields to depend on the user's answer to the <select> element that comes first. If they answer "First" then questions 1, 2, 3 and 4 should be disabled. If they answer "Second" then questions 3 and 4 should be disabled and if they answer "Third" none of the questions should be disabled.
I am using a validating form plug in for jquery and I have a question about it. Let this function will be an ex.:
[Code]....
'e' is the name attribute of one form element, but can I choose more elements using jquery (CSS) rules like this: input[name*=e] or how can I do something similar?
I should imagine others here have experienced it. The user completes your form, and they unintentionally input their email address incorrectly. Then when you reply to their form, you then get the mailer daemon returning your email! Now, there's a couple of ways that some websites try to solve this problem - some ask the user to input their email address twice, some show the forms results on the next page, so that the user has a last chance to check, before completing the submission. Are there any other ways of trying to ensure that, as much as possible, that the user inputs the correct email address?
I'd like to be able to submit hiddenform with the firstnames array equal to ['Joe', 'Bob', 'Pat']. But I seem to be getting an awful lot of ['', '', ''] no matter how I go about it.
I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:
I want to make few forms but 1 submit button. I want to do 1 page , 5 forms , 1 submit button so when i click on the submit button it will send the 5 forms as 1 form.
The problem is when i will calculate if quantitiy/buyquantitiy is an integer. The reason is that some products can only be seld as 4 items, and if you press 3 wou should get a message that says "Sorry a quantity of 3 are not aviable because there are 4 items in package". Can transfer 2 varibales into the function? Or have anyone any suggestion how to solve this.
I am a newbie to javascript. I have an asp text box which I want to validate for the number of characters entered i.e. I dont want user to enter more than 280 characters in the text box.
I have a form generated from a Perl script. The number of check boxes on the form is unknown until the time the form is generated. The names of the check boxes are created from some values in the database, based upon other user input.......<crazy, I know>
The user must choose at least one check box.
So, how can I write a javascript routine that will perform checking on an unknown number of check boxes.
