Clear Dependent Select Input If Parent Changed To Blank?
Mar 3, 2011
I have an ajax dependent drop down set up for location fields and am having trouble figuring out how to clear the dependent selects if the parent select is changed to blank.I set up a function to clearFields:
<script>
function clearFields() {
document.getElementById('cb_state').value = "";
I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:
I need to have two different DDL's where when I choose VAL = Dep1 on ARRAY1, I should see on the 2nd DDL only elements with parent corresponding to Dep1 ( PARENT =10).
I have a two level dependent select function, when level 1 changed, level 2 will change content with level 1, level 2 only change when level 1 "changed", if I use javascript to change the level1 value, level 2 won't change,for exaplme:
$('#level1').val(3);
the level 1 select will change to the option which value is 3, but it won't trigger the change event, therefore level 2 does not change anything, how to change level 1 by and trigger change event.
creating --Dynamic dependent cascading select using Ajax.It should not use asp .net, I need to add the code in a text field to generate this kind of cascading customized field.eg. initially we need to populate a select list from database. Then, on selecting an option the next select list needs to get populated with corresponding values, then again on selecting..the third list needs to get populated --this should happen dynamically(with no page refresh).
I have to create two dropdownlists that are dependent In my first select tag there are 4 selections ,,, year,quarter,month and week. and in second select it should automatically populate..If user select year from first select in second select values should be 1 to 365.. if quarter values in second select(dropdown) should be 1 to 4. if month 1 to 12 and if week is selected 1 to 7.
I am having 2 input fields. Both will have only the integer values. Its a minimum and maximum values. The condition is The minimum value of the 2nd input field should be greater than 1st input field. and 1st input field value should be minimum than 2nd input field. For that I tried with
I have a form where users need to be able to change a particular value in a <select> but need to confirm that this is what they want to do under certain circumstances. I have the script firing up ok and prompting the user, but I'm darned if I can figure out how to undo the change if required.
What I want to do is something like document.form.object.value=document.form.object.oldvalue but I have no idea what the correct properties are.....
So, how do you roll-back the selection in a <select>?
How can I trigger a jquery event for when a user changes the option that is selected in a select statement? I need to update a variable with the new selected item when this happens.

I've noticed that the change event isn't fired on a text input when it's value is changed by JavaScript. It fires just fine when I type in the input and then lose focus. Example:
After a user successfully logs in, I'm hidng the login div, and displaying the 'loggedin' div. However, if someone clicks on logout, the username and password fields still have the login credentials in them. So, I need to clear those text boxes, along with the 'remember me' checkbox.
Here is my code:
I've tried single quotes, double quotes and other variations. Nothing is working.
However, that 'alert' does show the value in the username box.
Here is the code for the login, and loggedin divs and forms:
Just a noobish question here, is it ok to assign the same id, name, and class to each form object as long as they are unique per form object?
I.E. - id="signout" name="signout" class="signout"
I have one document that resides in an iFrame, and it contains anywhere from 1 to 4 forms, depending. There is a dynamic content area that will display between zero and three forms, each named uniquely, associated with files that exist in a database. Regardless of the number of forms associated with a file, at the bottom of the document is one last form named NewDoc - this last form is used for uploading a new file into the database, or replacing a file.With one exception, this is working flawlessly.The user is supposed to choose a file for upload, use a SELECT input to say what document type it is, then click on the submit button.
What is actually happening, however, has me confuzzed. When the submit button is clicked the first time, the value of the input="file" element becomes blank and nothing happens. If a file is chosen, again, and the submit button clicked, it uploads with no problem and the database does what it's supposed to. But if I refresh the document and try, again, same thing - the file disappears from the form element and the form does not submit.First, the forms (all three, just in case):
I would like to clear a search input field on focusout(), without extra button for reset or something similar. I filter list when users type something in search field but when they click outside the form, search filed should be cleared.
It seems using the JQuery .val() function for FILE inputs doesn't work correctly in IE. That is, I can't change the value (file name). I'm trying to clear it, using .val(''). This works in Firefox but not IE.
How do I change the background colour of an input box in a form as soon as the value is changed? Also the background should revert back to it's original colour if the user decides that they do not want to make any changes and hence retype back the orginial value.
I do not want the background to change after the user has moved to the next form field but as soon as the value has been changed.
So before I used jQuery I had this approach to set select field as not selected. So the question is what would be the equivalent way to do it in jQuery? Code JavaScript: if (tag == 'select'){ this.selectedIndex = -1; }
I have a long form in a tabbed interface, where I want to count the non blank fields on each tab (the form fields are text and checkbox inputs and multi & single select fields). The counting function is as follows:
// Input argument is a tab object function countFieldsOnTab(obj){ var counttext = obj.find('input:text[value!=""]').length;
[Code].....
The counts of text, checkbox and multi-select fields works, but the single select count doesn't return what I want. The default option in single selects is a default where the value is blank "<option value="">-- make a selection -- </option>. These will be found as selected options.
How do I count only those options have have a non-blank selection?
