Clear All Optgroups And Options From A Select List
Aug 4, 2006
I have a multiple select list that is created dynamically based on a previous selection on an asp page. The first thing I do is to clear the curent option list by
document.form1.itemcross.length = 0;
The only problem is that it leaves the optgroups. How do I also get rid of the optgroups?
I have two select lists, the first one has three options in it, What I need to have happen is once a option is selected in the first drop down, the second drop down will be populated with the remaining two options.
how to clear value from ajax selected value, the code i use from thread daved83 about AJAX dropdown list. i have modified a little for that code, the code is like below

How to clear a list of contents in a combobox in javascript.I mean i want to clear the contents of the combobox and want to add new contents in the same combobox.Ex:I had 2 entries in a combobox as 'test1, test2'.I want to clear the data and want to add new entries as 'asd, asds, asdssd'.
I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost.When I select the first option nothing appears in the second option.
While appending the option-elements to the targetselect the original option-elements disappear (exactly at step of line 13). This is unwanted behaviour.
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 select dropdown with several options. The user selects an option and fills out the following few fields. If the user then changes his mind and changes the option in the dropdown, I want all the fields - or just the ones already filled out - to be cleared.
Note: reset() of the form is not an option as there are other things going on (hide/display of fields based on the dropdown option selected).
I have 2 lists and function to clean them function del_sel(option){ if (option == "1"){ document.forms[0].list1.innerHTML = ''; }if (option == "2"){ document.forms[0].list2.innerHTML = ''; }}
How to make this function shorter & without options? Something like that: function del_sel(option){ document.forms[0].option.innerHTML = ''; }
The problem is that this code returns mistake: function del_sel(option){ document.forms[0].option.innerHTML = ''; } ... <input type='button' value='Delete onclick='del_sel(form.list1);>
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 = "";
The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.
Code: //creates the Project dropdown list while ($proj = mysql_fetch_array($project)){ $id_proj = $proj['projid']; $name_proj = htmlspecialchars($proj['projectName']);
[Code]....
I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.
The user must bem select options in this 4 files in order, for example, he must bem select first "First Choice" next "Second Choice"... The options not be same.
I've been playing around with the following code for days already and still in the dark tunnel. Can someone tell me what's wrong with the way I've coded it?
var cell1 = row.insertCell(0); var selOpt = document.createElement('input'); selOpt.setAttribute('type', 'select'); selOpt.option = document.forms[0].Country.option; selOpt.setAttribute('name', 'AnotherCtry'); cell1.appendChild(selOpt);
<edit>What I'm trying to do is to copy the options of the Country to another select which I've allowed the users to 'add' to the current row.</edit>
I have a select and list of options. I have onkeypress event on the select input. As the user types I am trying to match the entered key strokes to the entries in the options and setting the selected value to the first match.
The problem I am facing is this: My options have 10000,0000, 10001, 1111,0001. Say I type 10, with less than one sec delay I consider them as one unit. So I try to find whether there are any entries in the options which starts with 10 and setting the value. But brower is considering the last entered key stroke , in this example 0 and setting the 0000 which is the first match.
Is there any way that I can stop the browser from doing that or any idea?
I've searched the web and every tutorial I can find says the same thing, and I am doing what they say, but it's inexplicably not working. Basically, I'm using a nested object to populate a select box using the new Option() method. Unfortunately, when I include the new Option line, it breaks the loop and does not add anything.
I have 8 pages that are very similar. The only difference is the select options with different group of names on each page. I am using a global script.Is there a way to have a central point with array of names that would write or function in the select option depending on the page.Example below
I have a page that displays a list of people playing in a tournament. I need to be able to generate a Leaderboard based on which players are manually selected by the admin. Next to each person there is a drop-down list. An admin can go in and select a "slot" that a player should be in on the leader board from 1 to 8, or leave it blank if none. What I need to figure out how to do is the following, when a change event happens on a drop-down list, and say the value 5 is selected, I need to check to make sure that 5 is not already selected in one of the other players drop-down lists, in other words, that the 5th leaderboard slot is not already full. if it is, display an error message and make them change that one first. how to do that with jQuery? I'm thinking it will have something to do with the each() function, but not sure exactly how the logic should work.
I'm making a <select></select> with lots of <option></option>. It contains all possible options. Because of the length of the list, I also have an <input type="text">.
This is what I wish to do:
onKeyDown I want all options that don't contain (or begin with, it doesn't matter which one) the typed letters to be removed from the <select>.
My problem is that I don't know of any code to find words and identify letters.
Is it possible to reorder the options in a form select box with jQuery, either by drag and drop or by up and down arrows/controls?I have a form select field that users use to choose an item to edit. I'd like users to also be able to reorder items in the select box to change their display order.In the end, I'll likely send order changes to the server via AJAX.
i need to remove some options from a <select> but i need to get it by name
so i have <select name="imageList"> <option>test1</option> <option>test2</option> <option>test3</option> <option>test4</option> <option>test5</option> <option>test6</option>
i know i need to use the .removeOption("test4"); to remove it but i dont know what to use so it selects the imageList <select>
I currently have a form that the checkboxes are automatically populated. There is over 1000 checkboxes in total, 48 of these checkboxes are designed as main topics, when the checkbox for one of these 48 are ticked, it checks all sub catergory checkboxes as well as populates a <select><option> multiple list with its value. When unchecking one of the 48, it unchecks all its sub categories and removes them from the <select><option> multiple list.
The problem I am having is, when i select one of the 48, which populates the multiple list option and checks all sub categories... i go to uncheck one in the sub categories, which successfully unchecks the main category (as it indicates they are not all selected). It also successfully removes the sub category from the multiple select option list and its main category (which became unchecked).
When I go back to check the main category which makes all the sub categories checked... it re-populates the <select><option> multiple list with the values creating duplicates. I need a proper way of when I check a box, it scans the multiple <select><option> list to see if it already exists, then adds it again if it is not there. I have tried the following jquery:
but it seems the length always comes out 0 (zero). I need a fast and efficient way of doing this there is over a 1000 checkboxes that can be checked and need to populate this list.
