This should be really simple but I can't get it to work, how do I disable and add a class to an input? Let's say I've got an input field with id = name, this is how far I got,
$("input#name").attr("disabled");
What am I doing wrong here? Any help would be greatly appreciated, thanks in advance!
You need to give .attr() a second parameter (the value to set, otherwise it gets the value), true in this case ("disabled" works too, but a boolean is desirable for a few reasons here):
$("input#name").attr("disabled", true).addClass('myClass');
.addClass() then adds that class to the element.

I'm already excluding one input, and it adds the success class (which I don't mind)
$('form').parsley({ excluded: '[data-parsley-sum-total="all"]' });
but there are a number of other inputs that have no validations on them, and I don't want the 'parsley-success' class added on submit. If I add them to the list of excluded inputs, it still shows the 'parsley-success' class after submission. I'm just removing them manually right now on submit, but is there an option to not give them the class in the first place?
Using parsley 2.0.7
Thanks in advance for any help.
Edit:
In case this helps, my inputs I'd like to have the validation show up on are all in a single div like so:
<form id="f">
<input>
<input>
<div id="d">
<input>
<input>
</div>
I'd like to do something like $('#d').parsley() but that obviously doesn't work.
Also, besides using parsley excluded like I mentioned above, using data-parsley-group="" doesn't work for me either, both just exclude from validations, but don't solve the parsley-success problem for me.
Interesting point, it should be easier.
It's not too hard to get what you want though. You can listen for parsley:field:validate event, and toggle a class "no-constraint" depending on if it has constraints or not. A simple tweak to your CSS file will give the result you want.
How to set the value of a check-box to checked dynamically using dojo? In dojo toolkit site I saw it was written to use key value pair for setting the checkboxWidget but am unsure about the approach. Can someone please suggest?
Here is my approach but it doesnt work .How can I fix this?:
checkboxWidget.set("","checked");
If you use set to assign a value to a property, the first parameter is the property name followed by the value.
checkboxWidget.set("checked", checkedValue);
Am I under the wrong impression that jquery or JS can retrieve the values of radio buttons in a form? The reason i ask is because in my code the script i use to check for all fields in a form, does not seem to recognise the value in id="contact2" in the form, which is a radio group. I have posted my code at jsfiddle.net and would appreciate some feedback as to how I can correct this. Many thanks
Fiddle: http://jsfiddle.net/xGrb9/
You need to do it like this:
$('input:radio[name=bar]:checked').val();
Because of how radio buttons are checked/unchecked and their values are stored. (from the jQuery docs). You also need to make sure that the radio buttons have different IDs, which is a classic gotcha.
Finally, when testing if a radio button has not been selected at all, make sure to test against undefined and not an empty string for compatibility across browsers.
EDIT: looked at your code, and you need to do two things:
1. Change IDs of the buttons, to something like "contact2a" and "contact2b" so they are unique.
2. Change your var customer2 = line to var contact2=$("input[name=contact2]:checked").val();
Change this line:
var contact2=$("#contact2").val();
to:
var contact2=$('input[name="contact2"]:checked').val();
You need the checked because otherwise it finds both inputs.
Also, technically, all IDs should be unique, ie, not used on 2 elements on the page.
You should be able to use .val()
See this: http://api.jquery.com/val/
Both of your radio buttons have the same ID. That doesn't work in HTML. You'll have to refer to the buttons separately and select the one that is checked.
You can simply call
$("[name=contact2]:checked").val()
I have a form which has many elements (e.g. textarea, input, select), after users have entered some data the states of these elements should change.
For example, an input[type="radio"] element will have the attribute checked="checked" if a user has checked it. The value attribute of an input[type="text"] element will contain the text entered by user.
The problem is that the html string returned by $('#form1').html() does not contain these data.
Feel free to take a look at this example:
http://jsfiddle.net/cmNmu/
You can see that no matter what your inputs are, the html returned is still the same (having no attribute data).
Is there any easy way to collect the html including their states?
Thanks in advance.
use below code getting the value of input type text via jQuery
alert($("input:text").val())
Maybe you could use the 'onblur' event handler to set the value of the element when you leave it
You should get the value using :
$('#form1').find(':input').val();
$('#form1').find(':radio[name=gender]:checked').val();
if you have multiple input then you can filter them bu their name or class or even id. Then you will need to select input using .find(':input[name=input_field_name]'). My Suggestion is : use name property instead of other property if you want to use form.
People usually use $('#form1').serialize() to get the values. If html() doesn't return both the source and data, I don't think that there is something you can other than manually constructing the full html by looking at the data.

By using the jQuery formhtml plugin written by gnarf:
jQuery html() in Firefox (uses .innerHTML) ignores DOM changes
The changes in the input elements can be reflected in the html string returned by formhtml().
Thank you very much everyone.
I need to access to a value in a checkbox, the atribute value has content, so i need to place the id somewhere else i created a label, but i have not access to that value
alert(check[i].label); // doesnt work
where else can i place a value in checkbox.
Please dont write that i can do this
<input type='checkbox' id='bla' name='mybla' vlaue='myvalue'> Hy
Where can i place some other values ?
I tryed with this
<input type='checkbox' id='bla' name='mybla' vlaue='myvalue' label='myothervalue'> Hy
first i get all checkbox ect... and in the for loop i did this
alert(check[i].label); // doesnt work
How can i do that?
It is indeed possible to store the extra data as a custom attribute on the <input> element. When you want to read the value, you can do it like this:
alert(check[i].getAttribute('label'));
Since you have tagged the question jQuery, here's the trendy version:
alert($(check[1]).attr('label'));
See these discussions if you are woried about using custom HTML attributes.
When I am being tempted to do this, I prefer to use a related hidden element to store the "other value". It feels cleaner to me, and I also don't have to wade through the validation warnings that otherwise could come at me.
Is that something you can use here?
