I have a web page with 3 forms on it. Not nested, just one after the other (they are almost identical, just one hidden variable that's different). A user will only fill in one form, and I'd like to validate/etc all the forms with only one JS script.
So how, when a user clicks the submit button of form#1, do I make my js script only deal with the fields in form1? I gather it has something to do with $(this).parents , but I am not sure what to do with it.
My validation script (which I used elsewhere, with only a single form) looks something like so:
$(document).ready(function(){
$("#submit").click(function(){
$(".error").hide();
var hasError = false;
var nameVal = $("#name").val();
if(nameVal == '') {
$("#name").after('Please enter your name.');
hasError = true;
}
if(hasError == false) {blah blah do all the processing stuff}
So do I need to replace things like $("#name").val() with $(this).parents('form').name.val() ? Or is there a better way to go about this?
Thanks!
i used the following method & it worked fine for me
$('#mybutton').click(function(){
clearForm($('#mybutton').closest("form"));
});
$('#mybutton').closest("form")
did the trick for me.
I found this answer when searching for how to find the form of an input element. I wanted to add a note because there is now a better way than using:
var form = $(this).parents('form:first');
I'm not sure when it was added to jQuery but the closest() method does exactly what's needed more cleanly than using parents(). With closest the code can be changed to this:
var form = $(this).closest('form');
It traverses up and finds the first element which matches what you are looking for and stops there, so there's no need to specify :first.
Eileen: No, it is not var nameVal = form.inputname.val();
. It should be either...
in jQuery:
// you can use IDs (easier)
var nameVal = $(form).find('#id').val();
// or use the [name=Fieldname] to search for the field
var nameVal = $(form).find('[name=Fieldname]').val();
Or in JavaScript:
var nameVal = this.form.FieldName.value;
Or a combination:
var nameVal = $(this.form.FieldName).val();
With jQuery, you could even loop through all of the inputs in the form:
$(form).find('input, select, textarea').each(function(){
var name = this.name;
// OR
var name = $(this).attr('name');
var value = this.value;
// OR
var value = $(this).val();
....
});
To get the form that the submit is inside why not just
this.form
Easiest & quickest path to the result.
