To submit a form by pressing Enter key the standard solution is:
<input v-model="name" v-on:keyup.enter="submit" />
But what if a form has many input fields? Is it necessary to add v-on:keyup.enter="submit" to every single one of them, or is there a simpler solution?
In this case, you should wrap the inputs in a form as follows:
<form v-on:submit="submit">
</form>
I have a validation function tied to a form's onsubmit event. When it runs, my <input> objects return empty strings in the value attribute even though I have typed in some text.
For example, the mark up is:
<input type="email" id="email" name="email" required>
the following:
document.getElementById("email").value
returns an empty string "" even if there is some value entered in the form.
I hope the screen shot below captures the situation:
I must be missing something very basic. What could it be?
There is more than one <FORM> in the page (but only one is visible at any one time), and there are more than one instances of <input id="email">. The wrong element with id email was being selected.
Hope this answer might be of use to somebody else too.
I have a country picker in my form like this:
<select class="bfh-countries text-left" name="country" id="country" data-country="DE">
</select>
I can get the value with jQuery like this:
$("#country").val()
but when i try to serialize the form with $("#myform").serializeArray() The value for "country" is an empty string.
How can i fix this?
I ran into this problem and it took me forever to find because there aren't any examples of it. What you really want to do is use data-name="country", which names the hidden variable on the back end as country. For the country picker, you can use the div tag as follows:
<div class="country bfh-selectbox bfh-countries" data-flags="true" data-filter="true" data-name="country" data-country="POSTBACK_VARIABLE_GOES_HERE"></div>
If you do this, you'll find a hidden variable that's added to the page as follows:
<input type="hidden" name="country" value="US">
The value above assumes you selected United States but it is entered as a 2 character code, which could then be entered as data-country above if you need to do server-side validation and display the page again without forcing the user to select the value all over again.
This was seriously a nightmare to find.
I have a link on one page which looks like this:
http://www.domain.com/sample-link#product_id
and on the other page (sample-link), I have this input field:
<input type="text" name="name" value="name" />
So, when I click the link from the first page, I want to open the "sample-link" page, and autofill the name field with the "product_id" text. Any ideas how can I make this?
Thanks in advance.
You'll just have to add a tiny Javascript snippet:
if (document.location.hash)
document.getElementById('testbox').value = decodeURIComponent(document.location.hash.substr(1));
For obvious reasons you'll have to adjust the id of the text box.
It gets a bit more complicated in case you'd like to pass more than one value.
The call to decodeURIComponent() is optional, but required in case you're passing characters like spaces or non-alphanumerical stuff (just to be sure).
im pretty new to jQuery, and i dont know how to do that, and if it can be done without editing manually the plugin.
Assume to have a simply form like that:
<form action="page.php" method="post">
Name: <input type="text" name="Your name" id="contact-name" value="" />
Email: <input type="text" name="Your email" id="contact-email" value="" />
</form>
When you submit it, both in 'standard' way or with ajaxSubmit(), the values of the request take the label of the field name, so in the page.php i'll have:
$_POST['Your name'];
$_POST['Your email'];
Instead i'll like to label the submitted values with the id of the field:
$_POST['contact-name'];
$_POST['contact-email'];
Is there a way to do that with jquery and the ajaxsubmit() plugin?
And, maybe, there is a way to do it even with the normal usage of a form?
p.s: yes, i know, i could set the name and id attributes of the field both as 'contact-name', but how does two attributes that contain the same value be usefull?
According to the HTML spec, the browser should submit the name attribute, which does not need to be unique across elements.
Some server-side languages, such as Rails and PHP, take multiple elements with certain identical names and serialize them into data structures. For instance:
<input type="text" name="address[]" />
<input type="text" name="address[]" />
If the user types in 1 Infinite Loop in the first box and Suite 45 in the second box, PHP and Rails will show ["1 Infinite Loop", "Suite 45"] as the contents of the address parameter.
This is all related to the name attribute. On the other hand, the id attribute is designed to uniquely represent an element on the page. It can be referenced using CSS using #myId and in raw JavaScript using document.getElementById. Because it is unique, looking it up in JavaScript is very fast. In practice, you would use jQuery or another library, which would hide these details from you.
It is reasonably common for people to use the same attribute value for id and name, but the only one you need to care about for form submission is name. The jQuery Form Plugin emulates browser behavior extremely closely, so the same would apply to ajaxSubmit.
It's the way forms work in HTML.
Besides, Id's won't work for checkboxes and radio buttons, because you'll probably have several controls with the same name (but a different value), while an HTML element's id attribute has to be unique in your document.
If you really wanted, you could create a preprocessor javascript function that sets every form element's name to the id value, but that wouldn't be very smart IMHO.
var name = $("#contact-name").val();
var email = $("#contact-email").val();
$.post("page.php", { contact-name: name, contact-email: email } );
This will let you post the form with custom attributes.
