I have a form and I need to validate a field against three rules:
1) The field need to be between 6 and 12 characters
2) It can only have letters, numbers, and the underscore
3) It cannot contain a space or other special characters
I want the validate to happen in real-time. I have the first rule working great. Here is the code for that:
I am completely new to javascript and am basically able to copy/paste code with some minor editing. What I am looking for is a way to have a 5 digit alphanumeric number generated inside a form field to be sent through php(mail).
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
I'm kind of confused about how to use regular expressions. I'm trying to have the user input a string or something and i have to validate it. The example im suppose to do has numbers only and must have 9 digits.
I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.
is there a function that get the name of the first input field of the current form ?
in my example below I want create an array of form field name and in the onsubmit assign all element's name to create a simple iteration to test if some elements in my array, that must be required, are null:
something like function verify(array of string)and in onsubmit something like return onsubmit(field1,field2,field3....) Code:
I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
It should allow 1 or two digits for the day of the month, then a separating character (" ", "/" or "-"), then 1 or two digits for the month, then 2 or 4 digits for the year.
Unfortunately it will accept anything above 2 digits for the year, which I understand why is happening but don't know how to fix!
I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

I am trying to make some dynamic effect to a HTML page using JQuery.<br/> 1.<br/> When the user clicks a Radio field, the field will be highlighted.<br/> 2.<br/> When the user clicks the Radio 'Man', <br/>a Input text box will be provided immeditely just below it.
Here is my simple HTML page, but I don't know how to do with the JQuery part:
So I have to ask some stupid questions and make sure that there is not something wrong in this simple syntax. I am trying to get input field attributes type and tagname by field ID. Heres the code..
Code JavaScript: var type = $('#' + input_id).attr('type'); var tag = $('#' + input_id).attr('tagName');
When I look in firebug I see there is the correct ID in input_id variable and that the input field with that id exists. But for tag and type variables I just get 'undefined' for reason unknown.. syntax is correct or?
I'm trying to replicate a feature found in hotmail, facebook, etc. When you type or select a recipient from an auto-suggest box for your message/email that recipient's name is put into the "To" field box and is encased (usually a blue rounded corner box) with a X to the far right. If the "X" is clicked the recipient is removed.
How can do you put the selected recipient into the encasing and insert it in the "To" field box? If there are multiple recipients how are they differentiated? For example, if there were a ";" between the recipients the semi-colon would separate the values.
here when i click the test button it will create a new test button inside div tag.But after that if i clicked new generated test button document.getElementById("test" ).onclick = function() is not working.how can i add functions to new dynamically created fields?
I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.
I'm trying to debug my expression that matches an alphanumeric with any number of dashes (including none), except at the ends and obviously disallowing two or more consecutive dashes.
im trying to set a textbox to only accept alphanumeric characters but it needs to accept a space in between each entry because it is a textbox all i can get it to do now is only allow numbers to be entered using the following code:
