Send A Form Value - A 15 Digit Number - To An External URL

Jul 6, 2009

I am trying to send a form value (a 15 digit number) to an external URL, so that the URL populates with the form value and opens in a new window when the user hits submit on the form.

The external URL that the form links to is in this format:[url]

Is there a piece of JS I can use that will populate the ORDERNUMBER field with the 15 digit form value when the user hits submit?

Generates A Random Number Between 1-1000 And Then Allows The User To Make Guesses In A Text Box

Apr 15, 2010

I'm having to write a program that generates a random number between 1-1000 and then allows the user to make guesses in a text box, answering to high or to low, until the correct answer is entered. I had the program working fine with using strictly prompts and alerts but when I tried to create a form I started having trouble.

JQuery :: Can Validate And Update Entered Value Before Doing Search?

May 14, 2009

When typing data into the autocomplete-field the list of matches is updated at every key pressed.Is it possible in any way to check and correct the data before doing the match. Or could you alter the way the match is done.The perfect example is when you have lots of users entering decimal values into a filed. Some people uses comma and some decimal-point. So you would like to permit both "2.23" and 2,23" to be matched against 2.23 in the list.[code]

Splitting Then Adding A Number Entered Into A Form?

Aug 7, 2010

I am making a form using HTML and java where you enter a number and it uses an equation then spits out another number. My problem is I want to split the number you put into the form and add it up. Example You enter"457829"Press "convert"And the first step I want it to do is"4+5+7+8+2+9=sumA"Then"sumA/8"So far I can only do the sumA/8 if I manually add up the numbers then place the sum in the form, here's the code:

Code:
{
var a = parsefloat(form.NumA.value, 10);

JQuery :: Validate Optional Fields Only When Data Is Entered?

Oct 13, 2010

I'm using jQuery validation on a form and I can't get it to only validate optional fields if the user enters something (should recognize the difference between this and the default value of the field, for text input fields). I know this is built in (I think) but I must be doing something wrong.

For example, phone number is optional but I want it to validate if the user enters something. Code for the phone in the JS file is:

jQuery.validator.addMethod("phone", function(phone_number, element) {
phone_number = phone_number.replace(/s+/g, "");
return this.optional(element) || phone_number.length > 9 &&
phone_number.match(/^(1-?)?(([2-9]d{2})|[2-9]d{2})-?[2-9]d{2}-?d{4}$/);

[Code]....

When I just put "phone" as the class it validates the field even if it is not edited by the user at all. For the required fields I put "required" as the class to validate them but I just read in another post that this is not necessary with the plugin...? I guess I am not sure whether the field should be define as optional by a class or in the JS file, and if it's the latter, how to do that.

Remove HTML Tagging From User Entered Data?

Dec 7, 2011

I have a website where people can create posts similar to FB(I hate that example but it's widely known) -- how do I strip HTML tagging out of the post before I put it in my db? (I'm using AJAX atm).The obvious crossed my mind with replacing "<" and/or ">" but I want those chars to be available when posting -- is there a way to do this or a way to print the data to my page as text even if it has those tags?

Dynamically Add Textbox For User Entry And Saving Data Entered?

May 5, 2009

I have an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.

Preserve User-entered Quote Marks In Form Fields?

Apr 10, 2010

I have a JavaScript application that needs to preserve double quote marks and apostrophes (" and ') that are entered into form fields by the user. The form data is passed through several screens using hidden fields.

Right now, apostrophes work because I have the input fields coded as value="". I have not found a way for JavaScript to retrieve the field's value if double quotes are entered by the user. If I change the parameter to value='' (single quotes) then the apostrophes probably won't work.

Is there a straightforward way for JavaScript to retrieve the field value containing quotes, so that I can manipulate it into a different string that can be easily passed between HTML pages?
